Abstract

We determine analytically the modulus of the second eigenvalue for the web hyperlink matrix used by Google for computing PageRank. Specifically, we prove the following statement: "For any matrix A=(cP + (1-c)E)**T, where P is an nxn row-stochasticmatrix, E is a nonnegative nxn rank-one row-stochastic matrix, and 0<=c<=1, the second eigenvalue of A has modulus Betrag (Lambda_sub2)<=c. Furthermore, if P has at least two irreducible closed subsets, the second eigenvalue Lambda_sub2 = c." This statement has implications for the convergence rate of the standard PageRank algorithm as the web scales, for the stability of PageRank to perturbations to the link structure of the web, for the detection of Google spammers, and for the design of algorithms to speed up PageRank.

Abstract

Neben Crosskonkordanzen, qualitativ-deduktiven Methoden und statistischen Verfahren gehört zu den Grundstrategien der Behandlung semantischer Heterogenität auch der Einsatz neuronaler Netze in Transfermodulen zwischen Dokumentenbeständen mit unterschiedlichen Inhaltserschließungssystemen. Sowohl die Frage, welches Netzwerkmodell am erfolgsversprechendsten ist, als auch die Frage, ob neuronale Netze im Kontext integrierter Fachinformationssysteme in der Praxis einen Mehrwert erbringen können, ist bisher in der Forschung kaum behandelt worden. Deshalb wurde diese Thematik in einer Kooperation vom IZ mit der Universität Hildesheim im Rahmen eines Promotionsvorhabens (Mandl, T.) erforscht
