TLDR
In this paper, a method and apparatus for preventing topic drift in queries in hyperlinked environments uses equivalence components for ranking pages containing information that is relevant to the topic of a user query input to a search engine.Abstract:
A method and apparatus for preventing topic drift in queries in hyperlinked environments uses equivalence components for ranking pages containing information that is relevant to the topic of a user query input to a search engine. The method includes the step of providing a query to a search engine, where the query represents a predetermined topic; retrieving at least one page associated with the query; constructing a graph representing the pages in memory; creating at least one equivalence component representing a subset of the graph; processing each equivalence component; eliminating the equivalence component in accordance with whether it matches the predetermined topic; and ranking the remaining pages.read more

Method for ranking documents in a hyperlinked environment using connectivity and selective content analysis
Krishna Bharat,Monika Henzinger +1 more
TL;DR: In this article, a set of documents are ranked according to their content and their connectivity by using topic distillation, and a relevance weight is correspondingly assigned to each node, and nodes in the second subset having relevance weight less than a predetermined threshold are pruned from the graph.
