Visualizing for different purposes

In my previous blogpost, ‘Information visualization, not only an academic practice?,’ I finished with the statement that there are many other authors (besides Manuel Lima) that talk about artistic ways of information visualization and the distinctions these cultural practices have from traditional (conventional academic) information visualization.

For example the Assistant Professor of Computer Science, Robert Kosara, of the University of North Carolina at Charlotte, wrote the article ‘Visualization criticism – the missing link between information visualization and art.’ In this he introduces the notions of pragmatic and artistic visualization to delineate between two very different approaches within the general field of visualization (Figure 1). The pragmatic approach is mostly practiced by computer scientists, is a technical, analysis-oriented process which visualizes data to generate new insight and amplify cognition (like scientific or information visualization) – while the artistic approach works with the sublime, an aesthetic criteria that means as much as, that which is “enigmatic and captivating at the same time (2007).” Artistic visualizations are usually used to communicate a concern, to let someone contemplate and reflect on something. But although pragmatic and artistic visualizations are intrinsically different, Kosara proposes the idea of visualization criticism, as a way to create a unifying set of aspects/criteria to discuss and evaluate these diverging types of visualizations. A critique does have its guidelines though and must abide to the following: have a neutral voice, state the facts, not being self-promotional and have the ‘clear goal’ of helping, by pointing out alternative approaches or researches. With this we might come to a deeper understanding of the field of visualization in general and bridge existing gaps between those different cultural practices within it.

Kosara - Pragmatic - Artistic

Figure 1: Robert Kosara’s schematic representation of the spectrum from pragmatic to artistic visualization, where the first focuses primarily on utilitarian products the second is more focused on sublime artifacts.

Pousman et. al. also talk about artistic visualizations or more specifically about artistic information visualization but places it under the proposed umbrella term casual information visualization together with ambient and social information visualization. They argue that the traditional definition of information visualization (from Card et. al., 1999)  is very broad encompassing projects that are related to, but traditionally not (conventional academic) information visualization systems. And define casual information visualization as “the use of computer mediated tools to depict personally meaningful information in visual ways that support everyday users in both everyday work and non-work situations (2007).”

This definition gives a solid foundation to make a clear distinction between projects to which we generally refer as information visualization, which Pousman et. al. define as “center” or “core” information visualization systems and those that lie at the “margins” or “edges,” (for which they give the examples of ambient, social and artistic information visualization). To exemplify this, Pousman et. al. argue that a lot of (conventional academic) information visualization systems are used as task-specific tools by ‘expert’ user-groups, who have knowledge and experience in analyzing problems in a certain field or domain; these tools enable them to explore and analyze data, generate, refine and test hypotheses which in the end lead to new insights. This is done frequently, with focused phases or episodes of use of an information visualization system; Pousman et. al. therefore “call this usage pattern of [information visualization] ‘episodic’ characterized by its duration, intensity, and goal-orientation (2007).”

Another major difference with casual information visualization systems, is that they support multiple types of insight. Insight can be intentional but it can also be a by product of e.g. going about your daily business, Pousman et. al. therefore argue that “the relationship between information and insight is more complicated than a simple linear relation (2007).” The insights that are gained by interacting for example with an (conventional academic) information visualization system could be large or small, depending on the knowledge a user has of that particular field. Pousman et. al. propose a set of different types of insight to define where casual information visualization systems generally focus on, namely awareness, social and reflective insights. Pousman et. al. do “note that the types of insight are not mutually exclusive, so a particular insight might have components of both analytic insight and social insight (2007).”

Awareness insight comes from maintaining awareness of a data-stream, which gives a sense of the fluctuations or shifting patterns in the data, without the need for some crystalized conclusion (Pousman et. al. 2007). Social insight is about social-networks, situations and life. It “is the sense of understanding of a social group and one’s place in it (Pousman et. al., 2007),” which is mostly contingent and thus subject to constant revision and reinterpretation.

“Reflective insight is insight about oneself, the world, and one’s place in it” – it is usually reached by providing a basis for reflection to contemplate “one’s personal and idiosyncratic thoughts (Pousman et. al., 2007).” Reflection is a common tool in artistic visualizations in general and is usually gained by means of defamiliarization which is a term Pousman et. al. lend from Bell et. al. to describe the way the normal or mundane is made strange, described as if seen through eyes from another planet. Through the mechanism of defamiliarization we might be able to “actively reflect on, rather than passively propagate, the existing politics and culture of home life [1] (Bell et. al., 2005).” Although, creating distance or new perspectives might be confusing, “the system’s confusion might lead to interest, reflection, and conversation amongst (Pousman et. al., 2007)” the observing users. Pouseman et. al. therefore conclude that “defamiliarization [...] makes the visualization stronger, even as it changes the notion of what it means for a system to provide insight (2007).”

Traditional or conventional academic, information visualization systems “maintain a functionalist perspective, in that they are designed to be helpful for a particular set of analytic tasks (Pouseman et. al., 2007).“ In contrast to this, artistic information visualizations or “data-driven artworks,” that work with either defamiliarization or the sublime (or both), differ according to Pouseman et. al. because they “may challenge some of our notions of visualization and computer-mediated understanding, our notions of what constitutes data, and may even question our ideas about the infrastructure of computer systems (2007).” Instead of being ‘helpful’ or useful for analysis, artistic information visualization (like other forms of art) is generally used for reflection on e.g. oneself, society, culture or philosophy but also on other issues, concepts or even objects, such as “computer networks, algorithms, and data itself (Pouseman et. al., 2007).”

Information visualization, not only an academic practice?

The definition by Card et. al. of information visualization as “the use of computer-supported, interactive, visual representations of abstract data to amplify cognition (1999),” is the basis of many authors. From this definition we can extract that this field needs a rather complex gathering of skills or good management of interdisciplinary teams to come to a meaningful product. If we take a deeper look – information visualization combines knowledge from the computer, information and cognitive sciences, in addition to knowledge from the fields of human-computer-interaction and graphical/visual design. Information visualization is still a relatively new phenomenon, since the ability for computers to work with high-end visual representations has only been developed in the last two or three decades.

Donald Norman’s illustration of the represented and representing worlds (1993, Ch. 3, p. 50)

Figure 1: Donald Norman’s illustration of the represented and representing worlds (1993, Ch. 3, p. 50). The represented world is shown in the top, e.g. the mountain, people and tree. While the representing world is shown below, in the form of a piece of paper with an abstract simplification of the represented world, namely the seven people and the tree.

Still, some of the knowledge used in information visualization, has a very longstanding history, it works e.g. with the tradition of conveying meaning through abstract representations. As Donald Norman argues in the chapter ‘The power of representation,’ of his book ‘Things That Make Us Smart,’ representations enabled us to do complicated tasks externally (Figure 1) – it is external cognition that makes us smart and he therefore argues that “the power of the unaided mind is highly overrated.” But Norman also writes that “the critical property of the representations supported by cognitive artifacts is that they are themselves artificial objects that can be perceived and studied (1993),” thus always leaving room for discussion and improvement. Card et. al. also feel that it is fundamental to gain understanding of the important role the external world has on our reasoning and thought; they have therefore defined cognition in their own work as “the acquisition or use of knowledge,” in combination with the term ‘external cognition’ as the “use of the external world to accomplish cognition (1999).” Card et. al. therefore agree with Norman, that “the use of the external world and especially the use of cognitive artifacts or physical inventions to enhance cognition, is all around us (1999).” They build further on his work and argue that defining these important concepts, gives a manner to “express the way in which internal and external representations and processing weave together in thought (Card et. al., 1999).”

From this short description of information visualization, one could already draw that information visualization is a field which is influenced by several scientific and academic fields. But there are more parties involved in the popularization of information visualization, as the research scientists at IBM’s Visual Communication Lab, Fernanda Viégas and Martin Wattenberg (1) write in their article ‘Tag clouds and the case for vernacular visualization.’ “It’s a time when the mainstream media is embracing sophisticated techniques born in university research labs—a time when you can open The New York Times and see complex treemaps and network diagrams. But just as exciting is the fact that some new visualizations, ones that get people talking and thinking about data in a new way, are emerging from outside the academy as well (2008).” According to them this phenomenon is happening so often that they felt it would be worth coining a term for visualization techniques which have found their origins outside the academic research communities – lending from the design world (2), they decided to call it vernacular visualization and explained it further by a case study of “one ubiquitous type of streetwise visualization: tag clouds (Viégas and Wattenberg, 2008)” (Figure 2) – which are truly ‘vernacular’, because they did not come from the visualization community or other scientific/academic fields and even break some (theoretical) ‘golden’ design rules (3). Still the popularity of tag clouds suggests that they just work well in practice as tools for collective text analysis of e.g. the contents of a blog or political speech – despite possible theoretical critiques.

The Master of Fine Arts and founder of VisualComplexity.com, Manuel Lima, praises the article of Viégas and Wattenberg for the way “they observed how the last couple of years have witnessed the tipping point of a field that used to be locked away in its academic vault, far from the public eye. The recent outburst of interest for information visualization caused a huge number of people to join in, particularly from the design and art community (2009),” resulting in the development of a multiplicity of projects. It is in the light of these developments that Lima decided to write his ‘Information Visualization Manifesto‘ – so that the “goals of information visualization” can be reemphasized and we might be able to make a “clear departure from other parallel, yet distinct practices” – which he feels is necessary because, “with more agents [e.g. non-academic designers and artists] in a system [such as in the field of information visualization,] you also have a stronger propensity for things to go wrong (2009).” Wrong, in the sense that for example a project is labeled as ‘data/information visualization,’ while it is clearly closer related to the artistic world. The big problem with this is that it confuses potential new information visualization students, with wrong expectations of the field, as Lima explains in response to a comment of Andrew Vande Moere of Infosthetics.com.

Lima mentions in his manifesto, that it is not that he wants to come over as “harshly censorial” towards projects that are related to conventional academic information visualization projects but e.g. “over-glorify aesthetics over functionality (2009).” This is because they are, in Lima’s vision, just part of the “continuous growth and maturity” within the field of information visualization – one of the many steps towards the “long progression for discovery” – in which “we are still trying to understand how we can find new things with the rising amounts of data at our disposal (2009).” However, it is still important that we make clear categorizations in the ever growing divergence of projects – Lima therefore ads to Viégas and Wattenberg observations of the emergence of vernacular visualizations, by arguing that we should also make a clear distinction between visualizing purely for aesthetic reasons, which he calls Information Art – or visualizing for the amplification of human cognition, which is the traditional goal (see Card et. al., 1999) of information visualization (2009). “Even though a clear divide is necessary, it doesn’t mean that information visualization and information art cannot coexist” – Lima even argues they should, “since they can learn a lot from each other and cross-pollinate ideas, methods and techniques [–] however, it’s important to bear in mind that the context, audience and goals of each resulting project are intrinsically distinct (2009).”

Besides Lima, there are many other authors (e.g. Kosara 2007, Pouseman et. al. 2007) which make a distinction between information visualization systems that amplify cognition and provide new insights, in contrast to visualization systems that are created for artistic reasons, such as the sublime. I personally believe (like Lima and other authors) that there is room for different cultural practices/subfields to coexists and learn from each other in the general field of visualization. To shut works out that are more focused on beauty then cognition would be a waste, by trying to analyze the work we can learn more about aesthetics and the pleasing and contemplative effects it has on the mind (although this might be bound to the personal preferences per person). Through analyzation there might be a possibility of detecting e.g. aesthetics methods or guidelines which could be applied to more general data visualization projects. Applying such aesthetics could possibly encourage discovery and exploration of new insights through ‘beautiful’ or aesthetic information visualization even further.

On a related note, I would also like to point out that Margarida Fonseca (a fellow student of mine) has also written a blog-post about information visualization and its popularization of lately. It is called ‘Information visualization, going public,’ in which she points towards a lot of interesting developments of the field in 2010. If you are interested in information visualization and want to know more about it, her post is a good starting point in which she also mentions some the longer historic aspects of the field. There have been more postings on the MoM weblog in the past about information visualization and on top of that, there will also be more postings from myself and my fellow information visualization students, (so stay tuned for more).

The vigilance of the Wikipedians

In the last couple of weeks I got some responses to my post concerning the revisitation of my Wikipedia article about Richard A. Rogers – in which I told that I was stupefied by the speed with which I was blamed for ‘self-promotion’ and ‘bias’ and about the fact that the original article was removed immediately after creation – these developments didn’t do any good to my mood or opinion of Wikipedia. In class there was a lot of discussion about the so-called ‘democracy’ of the encyclopaedia, which in our opinion was near to zero, after experiencing the fate of our well-made articles. Boldly I decided to copy-paste my PDF version of the article in a new article page to be able to show what I did for the assignment that week – fully expecting it to be deleted again within minutes – but strangely this time the article survived, for weeks even, so I was completely baffled. In the comments it was suggested that I had to clean-up the grammatical and formatting errors for the article to survive – but this was already the ‘second’ version in which I didn’t care about the format any more – my Dutch grammar, as my English, might not be perfect but still in my opinion it was ‘okay’. Of course I did use a translator for some specific words, but I would never use an automatic translation software for the entire page and just copy it, as was suggested.

A little later I received an email from Richard Rogers himself, responding to the article made about him, in which he asked what my plans were with the article. I responded that I wanted to keep the article, although I was growing tired of the Wikipedia after seeing my own article – and most of my fellow master classmates – rejected so soon. I really began to feel annoyed after going to all the trouble of creating the article in the first place but still I decided that I would like the article to be kept, since I took the effort creating it and I really felt the article was an addition to the encyclopaedia. My main argument for this was that Rogers is teaching in the Netherlands for quite some time now – he is mentioned frequently in the Wikipedia (on pages such as Media studies and New Media) – but he himself didn’t have a Dutch Wikipedia article. Luckily this made some sense to the Wikipedians who where interested and discussing deletion, so this time the second version of the article was going to stay, at least for a little while.

I registered at Wikipedia (under the name Xan82) and became an Wikipedian, this has the extra advantage of creating a discussion page for topics related to you and very soon I got some messages about the article of Richard Rogers. There were some tips concerning the discussion of deletion for the article – on which I was encouraged to participate and defend my views on why it should be preserved – but mostly there where tips on the protocols of Wikipedia itself which I’m expected to follow if I want to keep participating; you can read through these remarks at my discussion page. It is true that I’m still learning but I prefer to do that as I’m going, since there is no way of getting trough all the rules for content and formatting, remembering them, or let alone know how to use them! Eventually I did do some extra work on the article; I cleaned-up the formatting (again) and made some revisions, especially grammatical, to improve the overall quality of the article. And since I had asked Rogers, in my reply to his email, for comments/additions on the article and a recent picture to add – on which I got a quick response with lots of improvements for the article – I decided to make those additions too.

In retrospective our attempts to make an addition to the well-known online-encyclopaedia maybe started of a little to naive, for the Wikipedia is already nearing its tenth year of existence (the Dutch version was introduced a few months after the English version) and therefore has core-groups at its communities, which decide ‘what goes’ in their environment. These groups are relatively small but hold the daily reign over the encyclopaedia – and so it should be, as Shirky argues in his presentation ‘A Group Is Its Own Worst Enemy’ – although it is frowned upon to be a ‘vigilante’ in our society, in a lawless space as Wikipedia it is necessary for participants to take the ‘law’ into their own hands. “.. Rules of Order are necessary. Constitutions are necessary. [..] Group structure defends the group from the action of its own members [1].”

If we would have read Rogers oration ‘The End of the Virtual’ before we started editing – we might have picked-up on the existence of the Wikipedians ‘vigilance’, which means: ‘the action or state of keeping careful watch for possible danger or difficulties’ – as he writes that although “.. the editors are unpaid, [they are] committed and highly vigilant. The vigilance of the crowd, as it is termed, is something of a mythical feature of a quality-producing Web, until one considers how vigilance is performed [2].” A fairly strong point of the encyclopaedia, for without ‘vigilance’ how would for example vandals be kept at bay indeed? It is by the grace of the new technologies that this is even possible, or as Rogers and colleagues have termed, because of “networked content [3]” which “refers to content held together by human authors and nonhuman tenders, including bots and alert software which revert edits or notify Wikipedians of changes made [2].”

This is of course an explanation of the speed with which we attracted reactions from the Wikipedians; “Indeed, when looking at the statistics available on Wikipedia on the number of edits per Wikipedian user, it is remarkable to note that the bots are by far the top editors. The contention, which is being researched in the digital methods program, is that the bots and the alert software are significant agents of vigilance, maintaining the quality of Wikipedia [2].” We will probably get further acquainted with these ‘quality control mechanisms’ and other methods in our course by Rogers after the school-break, but I do feel that the hands-on experience so far has taught us a lot and can give further insights during the classes. Because after the reading of these theoretical backgrounds, I now might have an better understanding of what has been going on – but I still feel the immediate deletion of my article was a bit harsh – I really tried to make an good addition to the encyclopaedia and with some help from other Wikipedians I’m sure the vote for deletion would have been gone within a few weeks. Still it seems that you can’t count on ‘help’; you should try to do a job completely or not at all and if you really need help with something, ask for it! That has seemed to work for me so far..

Aphoristic message (overload?) by a CMC world

Communication is as old as humans (or humanoids) itself, from a grunt, a shout to a simple gesture – we have always had the ability to convey messages to others around us – whether we’re correctly understood is a whole other matter. ‘Aphorisms’ (the ability to make short, powerful and easy to remember messages) “have been around for thousands of years. Predating the written word, they allowed regular folk to carry around accumulated wisdom in their heads. As Erasmus put it, ‘An idea launched like a javelin in proverbial form strikes with sharper point on the hearer’s mind and leaves implanted barbs for meditation [1].’” Aphorism became an literary ‘art’ form, it became a specialism to craft a message that was short but still conveyed enough meaning to stimulate someone to a realization or even action.

Hippocrates

Hippocrates (engraving by Peter Paul Rubens, 1638)

The term ‘aphorism’ itself was first introduced in Ancient Greek in the work ‘Aphorisms of Hippocrates‘ and has been applied since then to other sententious statements in science, philosophy and literature. Examples of well-known aphorists include names as Confucius, Einstein, McLuhan, Voltaire, Tolstoy and the Dutch Erasmus of Rotterdam who was the first to ‘publish’ a collection of aphorisms under the name ‘Adagia’ around 1500. But as we came out of the 18th century, mass-illiteracy slowly but surely became something of the past in western-europe, and ‘short’ message writing became mainstream. First with the invention of the telegram – which became very popular during the 19th century – and gained serious competition, in 1876 with the introduction of the telephone, by Alexander Graham Bell. Eventually the telegram lost its position and even became absolute with the coming of the text message or SMS (Short Message Service/Silent Messaging Service) in the 1990s.

Still aphoristic messaging was never abandoned, it was merely in obscurity until it was ‘rediscovered’ by the public at large with the coming of mobile technology – or to use a well-known aphorism from Marshall McLuhan; ‘The content of any medium is an older medium’ [2] – even “Samuel Johnson said that eventually we would all write ‘aphoristically’. Consider how we often write today: email, text messaging, blogs, emoticons. These require little to no preparation and, all too often for the grammarians among us, usually eschew the finer points of grammar, including spelling, punctuation, and sentence structure [1].” More and more forms of communication have been introduced – with these developments people had the possibility to choose the medium appropriate for their message – for example, short ones with an SMS (although, today we can send multiple pages in a single SMS) and longer ones through email. With the coming of the online-application Twitter it was decided, that (somewhat like text messages) there had to be a maximum amount of characters (140 to be precise) that a person could use, forcing them to be short and preferably aphoristic.

The problem with this trend of dispersing the communication channels is that there are so many of them, how do we keep track of them all? Or maybe even more interesting, do we keep track of them all or just a few? Which channels are preferred by the public in general? Danah Boyd describes why she sometimes feels like a ‘bitch’ on her blog: “The problem with Web2.0 technologies is that each one wants to replace the INBOX (or at least be an additional channel). For example, there are private messages and comments on social network sites, direct messages and @replies on Twitter. [..] For me, it’s too much. Too much I tell you. And we haven’t even gotten to voicemail, text messages. Let alone all that’s coming [3].” As her metaphor might already imply, she puts the computer mediated communication (CMC) of email first, although I do suspect that if you have her number and giver her a call she might just be able pick-up. But the point she’s trying to make is that she suffers from ‘information-overload’ and that she has to make choices based on her personal preferences, as all of us have to do from the complex multiplicity of communication channels. “And there are huge issues here – should someone be flexible to others’ preferences or demand that others work around them? And here’s where I feel like a bitch. I’m asking people to work around me. Because I can’t cope with the alternative. And that makes me feel guilty and selfish. And I don’t know what to do about this [3].”

Personally, I somewhat feel the same as Danah Boyd, computers where supposed to make life easier but in certain instances, as with CMC it seems as if communicating is only more chaotic and dispersed. I’m not a very big fan for example of twitter, I do have an account and check every now and then but feel its a bit unnecessary and invasive. Besides that, I’m not very short in general (as you might have noticed), I have a lot of trouble making my messages short and to the point. Still, I do see how this skill could be useful, so maybe I should try to ‘tweet’ more and learn to be ‘aphoristic’.

My Wikipedia-page revisited…

Last week all of the Master students where assigned to start a ‘new’ Wikipedia article, which we all did but with which most of us had a lot of troubles. Most articles where deleted within minutes after creation, others where submitted to be deleted for various reasons. My own article about ‘Richard A. Rogers’, one of our Professors, was also deleted very fast – reason? – the article was biased and self-promoting according to the ‘WikiAdmin’ who deleted it.. The fact that the same page already existed in the English Wikipedia (@http://en.wikipedia.org/wiki/Richard_A._Rogers) and has about the same content doesn’t seem to matter!

Of course I was a little pissed at these developments, you try your best to make an honest contribution and get shot down for apparently no good reason. So when I was presenting my work for class that week I thought it would be fun to mess a little with the system, I opened the page again and put the article back, only this time I didn’t care about the mark-up.. and voilà – the contribution was allowed to live on! While I expected it to be deleted again real soon, it is still up there. Go and see for your self @: http://nl.wikipedia.org/wiki/Richard_a._rogers. But I still don’t understand it, maybe someone else could explain the logic behind this?

Social Networking Sites (SNS); are we helping in the shrinking of our own privacy?

Social Networking Sites (SNS) are commonly known to just about everyone nowadays or so it seems, who doesn’t at least own a FaceBook, MySpace, LinkedIn, Hyves, Ning account or combinations of these and many, many others! But do you know who has access to them? What’s exactly on them? Are you sure their isn’t some hidden fact which you’d rather not share with the world?

Privacy has become increasingly lower with the arrival of SNS but people seem to be more then ever willing to ignore that fact and have the idea that its better to be ‘open’. “If you’ve got nothing to hide… it shouldn’t matter” seems the common approach to the subject but the real issue is “In which situation or context shouldn’t your privacy matter”. Data-mining is an increasingly growing field and with more data on a certain person it can be easier to make a completer picture of someone, adding data found from network A to those found in your Electronic Patient Dossier (EPD) B to make conclusion C, which still might be completely wrong but is based on ‘facts’. This picture is used by companies to target specific messages and governments try to predict if you will be a ‘threat’ to them, the public or some other entity. To this end the Telecommunication centres have the obligation to retain certain data for at least six months up to an period of 2 years.. “for the purpose of the investigation, detection and prosecution of serious crime, as defined by each Member State in its national law [1].”

It is no secret that certain civilians are fed up with the way they are treated and some even try to make an example, by trying to get their ‘rights’ back, such as with FaceBook who allegedly violated the privacy of users by sharing information with ‘befriended’ third-parties. “.. the suit, filed in the Superior Court for California in Orange County, says. ‘Users may be unaware that data they submit … may be extracted and then shared, stored, licensed or downloaded by other persons or third parties they have not expressly authorized,’ the suit reads.” Your writings and photo’s are protected by law – so sharing without explicit permission from the owner infringes their rights and is therefore illegal – and this will be the basis for the lawsuit. Furthermore the suit describes how FaceBook has been slowly evolving from an regular SNS towards a huge data-mining empire which collects, analyses and redistributes content without permission. But of course FaceBook “.. said that it sees no merit to the suit and plans to fight it.”

The Dutch Internet provider XS4ALL made a movie about the subject called ‘Privacy Matters‘, which can be viewed below (with English subtitles, which can be turned on by the ‘captions’ (CC) option in the lower right corner of the screen) and started the Dutch website, privacymatters.nl. Watch the movie, its really interesting, looks nice and is only about 10 minutes long. It is from a ‘private’ corporation but I really do feel they handle the topic fairly and make some good points about the situation nowadays…

Wikipedia assignment: Is ‘WikiTrust’ the next step towards a more reliable online-encyclopaedia?

Once again the online-encyclopaedia Wikipedia is in the spotlight of attention; after years of various forms of praise, critique and academic studies – in which several different and overlapping aspects of Wikipedia have been discussed – the encyclopaedia has decided once again it wants to increase its authority on the internet. This should be achieved (somewhere this fall [1]) by enhancing Wikipedia’s reliability through the use of coloured text; this technique, called WikiTrust, is a project of professor Luca de Alfaro [2] from the University of California, Santa Cruz, which “is part of ongoing work [..] on reputation systems, online collaboration, and information trust.” The name ‘WikiTrust‘ can be a little misleading though, since it has no way of telling how trustworthy texts really are. “‘It can only measure user agreement,’ said de Alfaro. ‘That’s what it does [2].’”

Cross example of a colorized Wikipedia article

Fig. 1: Cross' example of colorized text.

The idea – of using coloured text in Wikipedia’s articles to increase reliability – isn’t exactly ‘new’; Tom Cross “.. a B.S. in Computer Engineering from the Georgia Institute of Technology”, wrote in 2006 the article ‘Puppy smoothies: Improving the reliability of open, collaborative wikis‘, which was published on the online, open, peer-reviewed journal First Monday. Herein he argues that the text in Wikipedia’s article’s should be coloured on its venerability – or grounded on the time that text has been in an article [Fig. 1] – his “.. proposal relies on the philosophy that bad information is less likely to survive a collaborative editing process over large numbers of edits (Cross, 2006).” This should raise the confidence that users have in Wikipedia, because they are provided with a visual tool which shows how venerable a particular piece of text is and with this users should be able to appraise the worth of an article. Cross’ thoughts had been mentioned again by Virgil Griffith, “a graduate student at the California Institute of Technology“, who programmed the WikiScanner in 2007 to increase the reliability of Wikipedia’s more ‘controversial’ topics. In his original WikiScanner FAQ, Griffith wrote: “Overall–especially for non-controversial topics–Wikipedia seems to work [..] As for other approaches, I think colored text is a promising direction for combating disinformation in wikipedia (2008).”

Now (in 2009) the basis of Cross’ brainchild, will have a test-run in the form of WikiTrust [Fig.2], which is essentially an extension of MediaWiki – the ‘Content Management System’ which is the ‘engine’ of Wikipedia and many others – “that implements an author reputation system, and a text trust system, for wikis. WikiTrust adds to a wiki a check text tab that enables any visitor to check the author, origin, and reliability of wiki text. Thus, visitors can easily spot spam, surreptitious changes, and information tampering [3].” WikiTrust works real-time, meaning that edits are analysed as users are typing (suddenly beginning to feel a little paranoid while writing this…) and by doing so it calculates the reputation of the author, trust of the text and its origin. According to the Wiki it should have the following functionalities:

  • Fig. 2: WikiTrust coloured text example

    Fig. 2: WikiTrust coloured text example.

    Text author: The author of every word in a text will be computed by an algorithm which should be able to resist “cut-and-pase, delete-and-reinsert, and most type of attacks ([WikiTrust developers even] claim, all attacks — try your hand at it and let [them] know!).” By clicking on a “check text tab, when the mouse pointer hovers over a word, [the original] author of the word [3]” should be shown by a small pop-up in the screen.

  • Text origin: By keeping track of the authors, WikiTrust is also (supposed to be) able to keep track of the revision of every word – when it was inserted or introduced and more importantly, by whom – this allows for examination of all edits (again, in the check text tab) and gives access to information on the author of the edit.
  • Text trust: Trust of parts of text will be calculated through the ‘reputation’ of the original author and all other users who have made revisions to it, the ‘trust outcome’ will then be displayed (again, in the check text tab) “via text background colors [..]: the background is white for high-trust text, and shades of orange that are the stronger, the lower the text trust [3].”
  • Author reputation: The reputation of the author will be calculated from the evolution of the content – “authors who provide lasting contributions gain reputation, while authors whose contributions are reverted in short order lose reputation” – in doing so, the hopes are that the system of reputation will provide “an incentive towards constructive behaviour [3].”

“The goal of the WikiTrust project is to facilitate online content creation and sharing. WikiTrust flags recent content changes that need scrutiny, and offers the text-tracking tools to investigate the context in which such changes were made. WikiTrust strives to benefit wiki authors, editors, and visitors [3].” The question of course remains… will these developments enhance Wikipedia’s reliability? In my opinion they will, for the reliability and credibility has already been proven to be moderate to high (Chesney, 2006). And in “.. an expert-led investigation carried out by Nature — the first to use peer review to compare Wikipedia and [the famous English encyclopaedia Britannica] coverage of science (Giles, 2005) –” the experts ruled that Wikipedia’s articles came close to Britannica’s in terms of accuracy. Of course, technical extensions like WikiTrust, will not automatically solve every issue within Wikpedia but every improvement will get us one step closer towards a better version. It seems to me that the academic community is still very ‘charmed’ by the Wikipedia – in several researches its been mentioned that is a great background reading to several topics – but it still remains questionable to use it as an authoritative source.

Book report on: ‘Ourspace – Resisting the corporate control of culture’ by Christine Harold

ourspaceThis book really hit an personal snare with me, because I have been trying to avoid most commercial expressions by any medium for years now. I really regard it as an invasion of my privacy – I didn’t ask to be battered with consumerism for all my life – but it seems that’s just how everyday day life has to work, or so you start to think after a while… Everything and everyone is a potential sell-out or ‘moral’ betrayer in this mostly monetizing world and so you start to feel you can do nothing about it.. And ‘zapping’ away immediately as the commercials come on, installing AdBlock Plus as a Firefox extension, ignoring hand-outs on the street, etc. don’t seem all that constructive as a silent protest after you’ve read a few pages of Harold’s book.

In the introduction Harold defines the difference between ‘our-space’ – which is the space of everyone – and ‘their-space’ the space of corporations and government. She describes how modern day ‘anti-heroes’ have fought for the reclamation of our ‘shared space’ all-around us, which are invaded daily – by mediums like, billboards, commercials, banners and even in the skies with air-balloons and plain flyers. However the tactics of  detournement used by the French Situationists International (like Guy-Ernest Debord) have changed since the 1960’s – the basic principals remain the same – turn the message around, jam their signals, make pranks, and most of all, expose the ‘hidden’ truths behind campaigns. As an example Harold describes how the sponsor for the American tobacco companies, Camel Joe, was used – in several remixes of the original versions – to show where a regular smoking habit leads too… Or the changing of digital voice boxes from Barbie dolls as a critical response to the fashion industries.

Clearly, these kinds of movements have roots in the leftist way of anti utopian-thinking – traditional ‘pointing out’ of misshapes in society to the larger public – by using the cultural means the corporations and governments themselves created and supported, to completely different ends, distributing their ‘remixed’ messages through the mainstream mediums. But even though these methods seem appealing, for Harold it holds no real threat to global capitalism. These kind of tactics eventually lead to new ‘brands’ with their own agenda, like her example of Adbusters, which has become so mainstream that they function as a buisness-model for other companies. They themselves have embraced these  kind of ‘guerilla’ tactics as marketing tools to make theirs brands seem cool, radical or even completely of charts to sell even more and more.

A real or even ‘true revolutionary’ alternative to all modern day consumerism can by found in the Creative Commons, copyleft or all-round open source communities – for they are exploring a new route to intellectual property rights – which encourages innovation and participation in creative processes. It is no mystery that Lawrence Lessig has made great contributions, by legal and philosophical means, to our modern day internet culture – and it is therefore no surprise that Harold advocates and promotes his work in this beautifully and wittily written book – which was made with much attention, details and great concrete examples to put things in perspective.

Christine Harold (Ph.D., Penn State, 2002) recently joined the faculty in the Department of Communication at the University of Washington, Seattle. Previously at the University of Georgia, she teaches courses in rhetorical theory and criticism, popular culture, and social movements. Her research focuses on the relationship between commercial culture, rhetoric, and the possibilities for political engagement within contemporary capitalism. Her first book, OurSpace: Resisting the Corporate Control of Culture (2007, University of Minnesota Press) examines culture jamming as a response to corporate power. It advocates an “open content” ethic as one way to promote a robust public culture. Source: http://faculty.washington.edu/charold/info.html

Wikipedia; de controversialiteit van een ‘open’ applicatie (Afstudeer Scriptie – HvA)

Wiki-controversie-CoverIk ben nog niet zolang geleden afgestudeerd in de richting ‘Interactieve Media’ van de Hogeschool van Amsterdam, ik heb ervoor gekozen om dit doel te bereiken d.m.v. een scriptie. Hierin heb ik mij hoofdzakelijk gericht op de Online-Encyclopedie Wikipedia en de ‘controversialiteit’ omtrent deze open applicatie; hierbij was mijn hoofdvraag: Vanuit welke zienswijzen is Wikipedia een controversiële applicatie? Ik heb hieronder mijn abstract, inleiding en hoofdstuk indeling gepost, zodat je een generale indicatie kan krijgen van de onderwerpen en schrijfwijze, maar uiteraard heb ik ook een versie online staan om te downloaden!

Abstract
Wikipedia is vaak in het nieuws wegens het controversiële karakter van de informatie die het bevat – toch blijkt dit volgens onderzoek eerder uitzondering dan regel te zijn – en de democratisering van kennis lijkt zich met behulp van ‘collectieve intelligentie’ (CI) gestaag voor te zetten. Lévy beweerd dat deze ontwikkelingen slechts het begin zijn en is bezig met het ontwikkelen van IEML voor de volgende stap richting ‘totale CI’. Maar verschillende auteurs vallen de initiatieven van de online open-encyclopedie aan – het zou door tekort aan expertise ‘onzin’ bevatten, helemaal niet neutraal geschreven artikelen hebben – en (vooral ‘CI’ zou) ons leiden naar een nieuw soort communisme. Toch zijn er ook veel voorstanders van Wikipedia die beargumenteren dat de betrouwbaarheid al vrij hoog ligt en groeiende is – er wordt meer gebruik gemaakt van wetenschappelijke bronnen – maar het is momenteel nog ‘dubieus’ om het als autoritaire bron te gebruiken. Mogelijkerwijs zou Wikipedia in de toekomst – eventueel met de implementatie van een aantal suggesties om de betrouwbaarheid nog hoger te maken – een beduidende rol kunnen gaan spelen in de disseminatie van wetenschappelijke kennis.

Inleiding
De online-encyclopedie Wikipedia heeft de afgelopen jaren in het middelpunt van de aandacht gestaan van verschillende artikelen en onderzoeken. De openheid, waardoor iedereen ten alle tijden aanpassingen aan een artikel kan maken, zorgt overduidelijk voor de nodige controversies tijdens het creatie-proces van de encyclopedie. Zo wilde VVD-Kamerlid Patricia Remak bijvoorbeeld, dat Wikipedia een stuk over haar veroordeling door het Gerechtshof, wegens het onterecht vangen van wachtgeld, uit haar artikel zou verwijderen. Een groep psychologen is ‘woedend’ omdat de antwoorden voor de ‘Rorschachtest’ in de artikelen is opgenomen – ze vinden het te vergelijken met examenvragen die zijn vrijgegeven voordat de ‘toets’ plaatsneemt. En de BBC News rapporteerde dat o.a. de CIA en het Vaticaan met behulp van de WikiScanner zijn ‘betrapt’ op ongewenste aanpassingen in de Wikipedia. “However, an expert-led investigation carried out by Nature — the first to use peer review to compare Wikipedia and Britannica’s coverage of science — suggests that such high-profile examples are the exception rather than the rule (Giles, 2005).”

Daarnaast is de openheid juist één van de bewezen theoretische hoofdregel van het hedendaagse Web 2.0; zoals Flew omschrijft: “Build applications that harness network effects to get better the more people use them … [or] harnessing ‘collective intelligence’ (2008: p.17)”. Dit laatste begrip staat bijvoorbeeld voor Jenkins centraal in de verklaring van Wikipedia’s succes (Flew, 2008: p.64). Door zich op Web 2.0 principes te baseren heeft Wikipedia het voor elkaar gekregen om één “of the fastest growing websites of the 2000s (Flew, 2008: p.17)” te worden. Het wordt dan ook meer en meer gebruikt en zelfs door third-party’s ingebed, zoals Google Maps waar het als extra informatie voor een object op de kaart zorgt en Google News dat experimenteert met Wikipedia op zijn homepagina. Maar Lévy beargumenteerd dat dit slechts het begin van CI is en dat we nog een lange weg hebben te gaan voordat we een volwaardige ‘kennisruimte’ hebben – waarmee we een ‘Cosmopedia’ kunnen creëren – een op-/naslagwerk met alle informatie en kennis ooit gecreëerd.

Maar niet iedereen bejubeld deze ontwikkelingen, Lanier waarschuwt dat o.a. Wikipedia ons (met de hype-term ‘Collectieve Intelligentie’) naar een nieuw soort ‘digitaal communisme’ aan het leiden is en wijst op de consequenties hiervan. Oud-eindredacteur van de encyclopedie Britannica, Robert McHenry schrijft: ” ’Wikipedia’s goal is to create a free encyclopedia — indeed, the largest encyclopedia in history, both in terms of breadth and depth and also to become a reliable resource.’ Note the adjectives, and the order in which they appear: free, largest (breadth), largest (depth) ‘and also’ reliable (2004).” Maar naar zijn idee kan de betrouwbaarheid van de open-encyclopedie helemaal niet worden gegarandeerd, vooral omdat er géén experts tijdens het creatie-proces aan te pas komen. McHenry beargumenteerd hierdoor dat: “the process allows Wikipedia to approach the truth asymptotically. The basis for the assertion that this is advantageous vis-à-vis the traditional method of editing an encyclopedia remains, however, unclear (2004).” In zijn opinie zou het onderzoek van Nature een bron van schaamte moeten zijn voor degene die het verzonnen en gepubliceerd hebben (McHenry, 2006). Karen Schneider kan Wikipedia ook niet vertrouwen door het tekort aan experts, daarnaast betwijfeld ze het democratische proces en de gewenste neutraliteit, ze schrijft: “.. the only truly neutral point of view is the point of view that is not clobbered into place by the loudest, most persistent voices, the hegemonic, patriarchal model of days of yore (2005).”

Er is dus vanuit verschillende hoeken hevige kritiek op Wikipedia geuit – Griffith beargumenteerd dat een groot gedeelte van Wikipedia’s controversialiteit te danken is aan de inherente technische tekortkomingen van het internet – we zouden de betrouwbaarheid op andere manieren moeten proberen te waarborgen. Toch is het géén ‘bevuild badwater’ zoals Vantyghem formuleert – het is nuttig voor zeer veel verschillende doeleinden – maar voor zekerheid moet er terug gegrepen worden naar ‘originele bronnen’. Nielsen verteld dat het gestructureerd gebruik van citaten stijgt in Wikipedia – en Chesney publiceerde in First Monday zijn empirische onderzoek naar de geloofwaardigheid van Wikipedia – de experts bevonden de onderzochte artikelen geloofwaardiger dan de te cynisch ingestelde non-experts (2006). Toch beargumenteerd Shirky dat de discussies omtrent Wikipedia voorlopig nog niet gesloten zullen worden (2008) – mijn interesse was hiermee gewekt waardoor ik besloot  om verder op onderzoek te gaan – ik zal proberen aan de hand van verschillende auteurs een antwoord te formuleren op de onderzoeksvraag:

Vanuit welke zienswijzen is Wikipedia een controversiële applicatie?
