| Research Abstract |
Social networks play important roles in the Semantic Web: knowledge management, information retrieval, ubiquitous computing, and so on. We studied social network extraction among researchers from the Web. Our system called POLYPHONET employs several advanced techniques to extract relations of persons, detect groups of persons, and obtain keywords for a person. Search engines are used to measure co-occurrence of information and obtain Web documents. We develop several new algorithms for social networking mining such as those to classify relations into categories, to make extraction scalable, and to obtain and utilize person-to-word relations. POLYPHONET has been used at several academic conferences, each with more than 500 participants.
