System and method for enhancing search relevancy using semantic keys

摘要

A method, computer-usable medium, and a computer system for searching for webpages are disclosed. Embodiments of the present invention provide a convenient and efficient mechanism for filtering results from a keyword search using semantic keys and semantic sub-keys, thereby enabling an increased number of irrelevant results to be filtered from a keyword search. The search query may be parsed to determine the focus of the query, where the focus may be used determine at least one semantic key for the search query. Each semantic key may be associated with at least one semantic sub-key, where the semantic keys and/or the semantic sub-keys may be used to filter the results of the keyword search. As such, broader keyword searches may be performed to include a larger number of relevant results, where the filtering mechanisms of the present invention may then filter an increased number of irrelevant results.

1. A computer-implemented method of processing search results, said method comprising:
determining a semantic sub-key associated with at least one keyword of a search query; accessing said search results generated from a search performed based on said search query, wherein each search result of said search results comprises at least one respective instance of said semantic sub-key; determining a respective frequency of said at least one respective instance of said semantic sub-key in each search result of said search results; and ranking said search results based on said respective frequency of said at least one respective instance of said semantic sub-key, wherein said semantic sub-key is selected from a group consisting of a hyponym and a numerical expression.
