METHOD AND SYSTEM FOR IDENTIFYING RELATED SEARCH TERMS IN THE INTERNET SEARCH SYSTEM

摘要

The present invention relates to a method and system for extracting correlated search queries, and more particularly, to a number of user identifiers to which each search query is input and a pair of search queries including the search query. The present invention relates to a method and a system for extracting an association search query that can measure the number and use the same to determine association between search queries.;In accordance with another aspect of the present invention, there is provided a method of extracting an associated search query, the method including: maintaining a database including a user identifier and a record relating to a search query received from a terminal of a user associated with the user identifier (the record is generated at predetermined time intervals; And counting the number of user identifiers received by the first search query per time interval with reference to the database to generate first user identifier number information, per the time interval with reference to the database. Generating second user identifier number information by counting the number of user identifiers at which the first search query and the second search query have been received, using conditional information using the first user identifier number information and the second user identifier number information Generating conditional probability information, and On the basis of the conditional probability information it is characterized in that the first one comprising the step of determining whether the search query and associated cross the second search query.;According to the present invention, by efficiently collecting and analyzing the data related to the search query received from the user to automatically determine whether or not the association between the search query to quickly extract the correct associated search query to provide a higher quality service to the user An associated search query extraction method and system are provided.;Search query, association, conditional probability information, correlation information, association index information
