Workshop on Web 3.0: Semantic Web and Web 2.0

After lunch, it is now for the second set of workshops, the first one is the Workshop on Web 3.0 Semantic Web and Web 2.0. Web 1.0 was just simply linking content, Web 2.0 is user-generated and involved a social change. But computers do not understand data. So Web 3.0 will be driven by technological changes and linking data is the power of Web 3.0. In Web 1.0, there is a producer and consumer, Web 2.0 there are a linkage of people which can be producers or consumers. There is a nice video on Web 2.0 that was shown.

The first paper in the workshop is on UbisEditor 3.0. It is about combining user modeling and ubiquitous computing with Web 3.0. UbisEditor 3.0 has ontologies that are used to drive the user modeling, there is collaborative ontology editing and user-created personalized ontology view. They visualize ontologies using Ajax-based trees.

The second paper in the workshop is on annotation system that uses dialogues in the user-generated content process. From the dialogues, natural language processing is used to extract the semantics and to verify the semantics, we can ask questions. But then asking the questions, is that too much burden on the user?

The third paper in the workshop is evaluating collaborative filtering algorithms for recommending articles in CiteULike, where they use classic collaborative filtering algorithms to find similar tags and users for recommendations. They then did a user study to see if the user found the tag relevant for the resource (in this case the cited article).

The next presentation in the workshop is on Working the Crowd: Design Principles and Early Lessons from the Social-Semantic Web. The InPhO project involves extracting semantics from the text and then presenting it to users, to rate its relevance over another term.
