Abstract |
In this talk, I will discuss ongoing user modeling research within our
CHIP (Cultural Heritage Information Presentation) project, http://www.chip-project.org/.
The CHIP user model is an overlay of the domain model, which stores user's ratings of
artworks and related topics. Currently we investigate: (i) how to extend the model with
FOAF specifications to express user interest and activities in objects; and (ii) how to
link to user data from social network and other Web 2.0 applications (e.g. user tags),
and use these for recommendations. Using FOAF in this way may help for example to solve
the typical cold-start problem in recommender systems and to offer the interoperability
across different systems or domains. However, to realize such an user model, issues of
storage, linking, representation and inference must be dealt with. In the presentation
I will discuss several applications using FOAF, and present our approach in CHIP. |
