Abstract
A system is described for discovering query intent based on search queries and concept networks. The system may construct frequency vectors from log data corresponding to a submitted query and at least one related query submitted to one or more search engines. The system may also construct a query intent vector based on the frequency vectors. The query intent vector may include frequency scores that represent the intent of the query.
Claims20
A method of discovering the intent of a query comprising executing instructions stored on a memory that cause a computer processor to:
- analyze log data stored on a memory relating to a first query submitted by a user to one or more search engines;
- identify a plurality of related queries that are suggested to the user, where the identified related queries are related to the first query;
- analyze log data stored on the memory relating to the related queries;
- construct a first frequency vector for the first query and a related frequency vector for each of the related queries based on the analyzing;
- determine a query intent vector comprising an array of entries, each entry corresponding to a search engine of a set of search engines, wherein the intent of the query is derived from the query intent vector;
- compare each entry of the query intent vector to a threshold;
- for each entry of the query intent vector that exceeds the threshold, identify the search engine of the set of search engines that corresponds to that entry;
- and
- provide search results to the user based on a search of first query on the identified search engines.

A product for discovering the intent of a query comprising:
- a memory;
- and
- instructions stored on the memory that, when executed, cause a computer processor to:
- analyze log data stored on the memory relating to a user query submitted by a user to one or more search engines;
- identify a plurality of related queries that are suggested to the user, where the identified related queries are related to the first query;
- analyze log data stored on the memory relating to the related queries;
- construct a first frequency vector for the user query and a related frequency vector for each of the related queries based on the analyzing;
- determine a query intent vector comprising an array of entries, each entry corresponding to a search engine of a set of search engines, wherein the intent of the user query is derived from the query intent vector;
- compare each entry of the query intent vector to a threshold;
- for each entry of the query intent vector that exceeds the threshold, identify the search engine of the set of search engines that corresponds to that entry;
- and
- provide search results to the user based on a search of first query on the identified search engines.

A system for discovering the intent of a query comprising:
- a processor;
- and
- a memory coupled to the processor, the memory comprising:
- query log data;
- instructions stored on the memory that, when executed, cause the processor to:
- analyze query log data relating to a user query submitted by a user to one or more search engines;
- identify at least one related query that is suggested to the user;
- analyze query log data relating to the at least one related query;
- construct a first frequency vector for the user query and a second frequency vector for the at least one related query based on the analyzing;
- determine a query intent vector based on an aggregate of a weighted first frequency vector and a weighted second frequency vector, wherein the query intent vector comprises an array of scores, each score being associated with a search engine of a set of search engines, and wherein the intent of the user query is derived from the query intent vector;
- compare each entry of the query intent vector to a threshold;
- for each entry of the query intent vector that exceeds the threshold, identify the search engine of the set of search engines that corresponds to that entry;
- and
- provide search results to the user based on a search of first query on the identified search engines.
