Which flavour does knowledge have on the web?

by , Category: Knowledge Management, Software Development

In recent debates within the KiWi – Knowledge in a Wiki project, the need arose to further refine and find a common understanding of the type of knowledge that is (ideally) managed and processed using (semantic) wikis. One of the proposals evolved around a conceptualization of knowledge put forward by Gabi Reinmann-Rothmeier, also dubbed the “Munich Modell” (Münchner Modell).

In the Munich Modell, knowledge comes in three states of matter: solid (like ice), liquid (like water) and gas (like water vapor).

“Frozen” knowledge is knowledge in its most tangible, manageable form, for instance the type of verified, expert-endorsed information you would find in an encyclopedia like the Encylopedia Britannica.

“Gaseous” knowledge, on the other hand, is knowledge in its least consolidated form: think for instance of the type of heated debate you might have with folks in a pub, which is arguably the least structured, most uncontrollable, but also the most engaging type of knowledge!

And the “liquid” form of knowledge, eventually, is the common knowledge of day-to-day-life. It’s probably fair to say that it becomes obvious mostly when in the process of changing its state of matter: When it is calibrated against “frozen” or informational knowledge or when it is debated, becomes “gaseous” knowledge that informs action. (If you’d like to know more about the Munich model and are able to read German, you might want to download the original article here – PDF, 365 KB).

When talking about knowledge that is managed, used or, respectively, that evolves online, I think it also makes sense to pay some attention to the type of community that is preferred by particular online tools or environments. The particular flavour of knowledge, in this sense, is simultaneously characterized and shaped by the state of matter of knowledge and the form of the community that applies.

N.B. The following is not an immediate translation of the “Munich model”, but rather a reconceptualization which tries to also consider that different community models (and their implementation through IT) also play a role for the whole spectrum of knowledge management on and with the web (e.g. for online communication and interaction, online publishing and documentation and maintenance of web infrastructures).

Web-Flavour 1: The Blogosphere – gas, gas, gas!

Hmm… sniff it! This is the flavour I like best because it is my flavour. On the blogosphere (and twittersphere), knowledge is exchanged, developed further and evolves almost like in a pub debate… Continue reading →

ESWC – Video Lectures about Semantic Wikis

by , Category: Conferences & Events, Semantics & Philosophy, Social Software

Sebastian Schaffert, coordinator of the KiWi project, just pointed readers of his blog to the video of his ESWC-Lecture
“Semantic Wikis – IkeWiki – A Semantic Wiki for Collaborative Knowledge Management”, also discussing knowledge management and why it should not be informed by quality management approach. Also published now is Peter Dolog’s talk about Semantic Wikis in general.

Semantic Wikis – Introduction to semantic wikis

Here is an example of an implementation of IkeWiki, an open source semantic wiki developed mainly by Sebastian Schaffert.

Jury Award for Semantic Wikis in eGovernment, and: Semantic MediaWiki for Wikipedia?

by , Category: Collective Intelligence, Internet & Media

An implementation of Semantic MediaWiki in public administration reiceved a jury award yesterday in the final ceremony of the highly coveted multimedia state award (Staatspreis Multimedia) 2008 in Vienna: Centre for Public Administration KDZ‘s platform for the cooperation of administrations (Plattform Verwaltungskooperation) in Austria, Germany, Italy and Switzerland received praise for its use of open, semantic technologies in their effort to further the collaboration between administrations and administrative staff. Those of you who can read German: read the response from Bernhard Krabina, KDZ, here or contact him here, if you’d like to learn more. The top state award itself went to HPC Dual, a combination of electronic and physical mail delivery.

Also published yesterday was an interview with Matthias Schindler, former member of board of Wikimedia Germany, at the occasion of the publication of a physical Wikipedia, i.e. a one-volume encyclopedia in print (publisher: Wissen Media, a Bertelsmann division). According to the English Wikipedia, “the volume is planned to include abbreviated entries for the 50,000 most commonly used search terms of the prior two years. The book is to be priced at 19.95 euros, with one euro from every sale going to the German chapter of the Wikimedia Foundation.”

The interviewers also asked Schindler for his “encyclopedic Wikipedia dream” – I hope his response will catch on in the Wikimedia chapters worldwide:

I would one day like to see a large edition of Wikipedia (including a German language edition), which makes use of the Semantic MediaWiki extension. The dream in a nutshell, without consideration of the current state of research and development: A wikipedia that can be read not only by humans, but also by computers, a Wikipedia that can offer concrete answers to concrete questions and that creates content individually for users, something that they can make use of; great if Wikipedia played the role of the first, mainstream Semantic Web application. While this is still in the process of coming together, there are enough other things for us to do.

(btw, my translation).

Concrete answers to concrete questions, a personalized Wikipedia – I am not even aiming that high at the moment.

Just consider the absurd amount of lists in Wikipedia, all of which are maintained manually. Take for instance the list of hardcore punk bands, the list of fictional countries (to be distinguished from the list of European fictional countries) or the list of military operations.

How often do you think these need an update? And if a new hardcore punk band is added – will the creators of the new article think about adding it to the list? What about articles which make make a reference to or mention things that are or should be on a particular list?

As a list has the inherent claim of being complete, it shouldn’t be left to humans to create and maintain them – leave that to the machines! Vote Semantic MediaWiki for Wikipedia!

Tag Recommender Evaluation – Anyone Can Particpate

by , Category: Social Software, Tools & Software

The IWIS Group at the Dept. of Computer Science, University of Aalborg, Denmark, have just opened up their evaluation of a tag recommender system they are building; the component is to be part of the wiki-based, semantic knowledge management system KiWi (itself based on IkeWiki). Anyone interested in participating, please send an Email to Fred Durão at fred@cs.aau.dk.

Hi,
We are conducting an evaluation of a tag based recommender system with personalization we have developed here at the IWIS group at Aalborg University (http://iwis.cs.aau.dk) and in the context of KIWI project (http://www.kiwi-project.eu). We would be very grateful if you could help us with this task.

The recommendater system is based on a set of algorithms we are evaluating. Later we are planning to plug it into the KIWI system and develop an appropriate user interface for it. Currently, we are evaluating it based on Delicious data (tags and content). The recommendations will be processed by our recommender system based on the tags you placed in Delicious.

As personalization is a crucial aspect to us, we will give you a generated username and password to log onto the Delicious Web site. Therefore please send an e-mail back to us that you would like to participate. You only have to tag a minimum 10 web sites of your preference. Tag as much as you can!

Afterwards we are going to email you a list of recommendations to web sites that you might be interested. These are computed by our recommender system. We will ask you to mark the recommendations by YES if the sites recommended suits your preference or NO if it does not.

The achieved results will be published to all participants after the end of the analysis.

People interested in participate of this evaluation please send an email to fred@cs.aau.dk.

Best regards,

Fred Durão and Peter Dolog
