Today, FOAF files are only utilized for publishing simple information about persons and their respective community. Our proposal is to extend a user’s FOAF file by an automatically generated user profile. If a general classification of interests (for instance in the form of a taxonomy) is given, these profiles can be represented in an IR-style fashion by histograms expressing the degree of interest in each topic. Our main assumption is that such user profiles can then provide good hints about the users’ expertise.
