Information retrieval based on semantic patterns of queries
First Claim
1. An information retrieval method, comprising:
- pre-processing a set of historical query information, comprising;
determining a plurality of semantic patterns based on a plurality of queries in the set of historical query information;
establishing correspondence relationships between the plurality of semantic patterns and a plurality of filtering and ranking operations; and
processing a user query, comprising;
receiving the user query;
retrieve a plurality of results in response to the user query;
determining a semantic pattern that corresponds to the user query;
determining a set of filtering and ranking operations that corresponds to the semantic pattern based on the correspondence relationships; and
performing the set of filtering and ranking operations on the plurality of results to generate a set of filtered and ranked results.

Abstract
An information retrieval method includes pre-processing a set of historical query information and processing a user query. Pre-processing a set of historical query information includes determining a plurality of semantic patterns based on a plurality of queries in the set of historical query information; establishing correspondence relationships between the plurality of semantic patterns and a plurality of filtering and ranking operations. Processing a user query comprises receiving the user query; retrieve a plurality of results in response to the user query; determining a semantic pattern that corresponds to the user query; determining a set of filtering and ranking operations that corresponds to the semantic pattern based on the correspondence relationships; and performing the set of filtering and ranking operations on the plurality of results to generate a set of filtered and ranked results.
