Web Mining Methods for the Detection of Authoritative Sources

Web Mining Methods for the Detection of Authoritative Sources

The innovative portion of this doctoral thesis deals with the definitions, explanations and testing of modifications of the standard PageRank formula adapted for bibliographic networks. The new versions of PageRank take into account not only the citation but also the co-authorship graph. We verify the viability of the new algorithms by applying them to the data from the DBLP digital library and by comparing the resulting ranks of the winners of the ACM SIGMOD E. F. Codd Innovations Award. The rankings based on both the citation and co-authorship information turn out to be better than the standard PageRank ranking. In another part of the disseration, we present a methodology and two case studies for finding authoritative researchers by analyzing academic Web sites.
