Using matrix representations of search engine operations to make inferences about documents in a search engine corpus

摘要

In a computer system including a search engine that receives queries and returns search results comprising zero or more hits from a document index, a method of post-rocessing queries and results comprising collecting search sets, wherein a search set comprises a query and at least some set of the search results provided by the search engine in response to the query from a corpus, storing the plurality of search set in reference symbol storage, identifying an analysis set comprising at least two documents in the corpus to comparatively analyze, retreating from the retrievable storage search sets containing at least one document of the analysis set, thus obtaining a group of one or more search sets, generating an inference between the documents in the analysis set based on which is search sets occur in the group.
