Methods and apparatus for using a modified index to provide search results in response to an ambiguous search query (4 de marzo 2003)
A system allows a user to submit an ambiguous search query and to receive potentially disambiguated search results. In one implementation, a search engine’s conventional alphanumeric index is translated into a second index that is ambiguated in the same manner as which the user’s input is ambiguated. The user’s ambiguous search query is compared to this ambiguated index, and the corresponding documents are provided to the user as search results.
Ranking search results by reranking the results based on local inter-connectivity (25 de febrero 2003)
A search engine for searching a corpus improves the relevancy of the results by refining a standard relevancy score based on the interconnectivity of the initially returned set of documents. The search engine obtains an initial set of relevant documents by matching a user’s search terms to an index of a corpus. A re-ranking component in the search engine then refines the initially returned document rankings so that documents that are frequently cited in the initial set of relevant documents are preferred over documents that are less frequently cited within the initial set.
