OntoWiki Kick-off in Leipzig

December 03, 2008 By: Andreas Blumauer Category: Companies & Institutions, Conferences & Events, Linked Data & Open Data, Ontology Engineering, Search Engines, Semantics & Philosophy, Social Software 1 Comment →

Virtuoso+DBpedia+OntoWiki together with several industry relevant uses cases – that´s about the formula of the OntoWiki project, which was launched yesterday in Leipzig.

Sören Auer and his team from AKSW at Uni Leipzig are the coordinators of this EU funded project which supports the development of innovative software products. All industry partners are SMEs which offer services for different fields like E-learning, E-tourism or Business Intelligence. Leipzig and OpenLink Software will work on an integration of OntoWiki & Virtuoso.

The first day of the meeting was, of course, dedicated to socialize and get to know each other. The mixture of the project team turned out to be well chosen – and in the evening we flew at higher game: We had a nice overview over Leipzig standing on the highest building of the town.

On the second day of the meeting Orri Erling, Program Manager at OpenLink Software, came up with an idea which is pretty forward: Why shouldn´t we provide OntoWiki as a Linked Data Browser, e.g. on top of DBpedia etc.? One possible outcome of this project.

Some other use cases which make already use of the existing OntoWiki system were demonstrated: Take a look at Vakantieland (…and start to plan your holidays in the Netherlands) and also at LinkedGeoData where a nice user interface can be tried out.

The Kick-Off Meeting will proceed with two workshops dedicated to semantic technologies and to Application Development with the OntoWiki Framework. Thanks to Sören and his team for the excellent hosting of this event!

Knowledge Management for Project Management: from unstructured to structured information

November 28, 2008 By: Jana Herwig Category: Knowledge Management, Social Software, Tools & Software 1 Comment →

KiWi – Knowledge in a Wiki session, pt. 2: This afternoon, we turned to the Logica use case, which is dedicated to the development and optimization of KiWi as a knowledge management tool specifically tailored to the needs of project management.

Regarding the use case requirements: As Daniel Grolin, a process expert and business architect at Logica (formerly WM Data), pointed out, what is most required at the moment is an application for designing processes, i.e. for designing the ways that people do things. This can be a painful process, in particular if one group of people (consisting of process designers) thinks about the ways that another group of people (e.g. the project managers) are going to do certain things – a collaborative approach should be able to

1) alleviate this challenge
2) generate commitment among the involved parties.

The primary users will be on the one hand the process engineers, and on the other hand the project managers who are the recipients and users of these processes.

In his presentation, Daniel Grolin chose one of four scenarios in which KiWi would ideally be employed: the risk analysis process – which is a vital process for Logica, as the outcomes of this analysis influence the decision whether or not a project will be accepted. From an architectural point of view, KiWi is going to mediate between the process guidance column – which consists of process and workflow features – and the final work product, i.e the result of a process, in this case the report of the risk analysis.

In practice this means that if, for instance, a user has selected the risk analysis process, the Kiwi core system and enabling technologies will provide concepts related to risk analysis, supporting the user in the tagging process. Wiki technology is already being used in the industry, said Daniel, but what is lacking at the moment is the integration of structure, and this is also where he sees the potential of KiWi as a knowledge management tool, and as a means to move easily from unstructured to structured information (by the way, if you are interested in using wikis in the enterprise, I also recommend this article: Wikis for Knowledge Engineering, and in Global Businesses).

Karsten Jahn

Karsten Jahn (Aalborg University) then gave us a preview of a possible user interface (i.e. not of the screen design, but the functionalities) which seeks to address one particular problem: Many companies use many different, sophisticated tools which operate fine on their own, but are not integrated (i.e. there is no communication or exchange of data between them). With KiWi, the aim is to develop a tool that is going to be able to cover all features and processes currently being taken care of by individual tools, to allow for an optimum of data integration.

To conclude, Rolf Sint (Salzburg Research) showed us screens of the current configuration of KiWi for Logica’s needs – the example below is related to the risk analysis process outlined by Daniel Grolin above.

What’s hot in the Semantic Wiki Community?

October 20, 2008 By: Jana Herwig Category: Conferences & Events, Social Software No Comments →

This morning I received an invite from Christoph Lange, Jacobs University Bremen, to attend a Birds-of-a-Feather meeting as an informal side-event/after hour to ISWC (this event label was unknown to me, but “Birds of a feather/ flock together”, so I assume that this must be a meeting of people who share the same interests). There’ll be lightning talks, open discussions and of course plenty of opportunity to network. Here’s a link to a wiki page for the meeting – please put your name on the appropriate list if you’d like to attend or give a lightning talk. The event is scheduled for Sunday October 26th, after the ISWC program.

People unable to attend physically, Christoph wrote, might consider participating in the Semantic Wiki Mini-Series Launch Event via ONTOLOG (= Open, International, Virtual Community of Practice on Ontology, Ontological Engineering and Semantic Technology), to take place online on Thursday, October 23, 2008, 10:30 AM PDT / 1:30 PM EDT / 7:30pm CEST / 17:30 UTC (click here for more details, time zones, registration procedures for first-time participants).

Here are some of the topics that have already been put on the wish-list for the Semantic Wiki Mini-Series (source):

  • usability vs expressivity
  • community building
  • uncovering more implementations
  • HCI: navigation of large, high-dimensional knowledge spaces
  • e-science (especially pharma research & biomedicine)
  • semantic wikis and mashups
  • recommendation and personalization in semantic wikis,
  • knowledge representation (expresivity vs. simplicity)
  • how to make business subject matter experts able to enter, review and validate
    meaningful information without them having to learn new words
  • what dialect of OWL supported
  • integration of semantic resources (Protege / OOR / MW / …)
  • content quality
  • integration of external data
  • a semantic wiki & OOR session
  • experiences with distributed collaboration
  • server-side infrastructure to support semantic wikis
  • survey of semantic wikis for vertical domains (e.g. HCLS)
  • integration with other tools / linking wiki content to other apps

If you ask me, there are more than enough topics not for a mini, but for a grand series of conferences on Semantic Wikis:) For updates, bookmark the homepage of the series.

Which flavour does knowledge have on the web?

October 09, 2008 By: Jana Herwig Category: Knowledge Management, Software Development 4 Comments →

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… (more…)

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

September 24, 2008 By: Jana Herwig Category: Collective Intelligence, Internet & Media No Comments →

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

September 19, 2008 By: Jana Herwig Category: Social Software, Tools & Software No Comments →

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
