Knowledge Management in Web 2.0

Knowledge Management in Web 2.0 (Seminar)


Any issues regarding the organization of the seminar should be discussed with Johannes Hoffart. I will be available for you every thursday from 15:00-15:30 for your questions in my office, B117. I would be thankful if you send an eMail in advance if you are planning to come, so that I know if we need additional time.

Questions and discussions can also be posted to our forum.


The presentations of our introductory course:

Presentation and Report

An example of structure and content of your report is given in this LaTeX template (the appropriate fonts for this template can be found at the page for the LaTeX TUD-Design). You are free to adjust this template to your specific topic, and to add additonal information where you think appropriate. We would appreciate if the report and presentation slides were written in English, but the presentation itself should be held in German. A powerpoint template for the talk is also available.

After your presentation, please send us your slides!

A digitial version of the report is required, alongside a printout of the final version.

A variety of collaborative forms of knowledge has emerged in the Web 2.0. Wikis are a good example, as they are used in various areas, for example, as encyclopedias (Wikipedia, Knol, Citizendium), as dictionaries (Wiktionary), as collections of quotations (Wikiquote) or of animal and plant species (Wikispecies). Other examples are question / answer portals such as Yahoo! Answers and WikiAnswers, social bookmarking services such as del.ic.ious, user rating portals such as Rate it all!, online social networks like Facebook or studiVZ, pictures portals like Flickr, video portals such as YouTube and many more. The seminar, however, also focuses on collections of facts such as Freebase or DBpedia, which derive from collaborative knowledge management and already belong to the Web 3.0.

The properties of the systems will be analysed and evaluated in terms of their potential uses in the students' major field of interest (such as computer science, social sciences, etc). Other Web 2.0 knowledge management systems may be studied.

A unique feature of this seminar is that it is interdisciplinary. Mixed student teams will be set up to work on a theme, e.g. computer science + psychology + economics. In addition, the students will acquire key skills, such as basics of scientific work and presentation skills in interdisciplinary contexts.
