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 search sessions in which each search query is input and a pair of search queries including the search query. The present invention relates to a related search query extraction method and system that can measure the number of search sessions and determine whether the search sessions are related to each other.;In accordance with another aspect of the present invention, there is provided a method for extracting an associated search query, the method including: maintaining a database including a search session and a record relating to a search query received from a user terminal during the search session (the record is generated at predetermined time intervals; Recorded in the database), generating a total number of search sessions by counting the total number of search sessions set per time interval with reference to the database, and referring to the database, a first search query per time interval Counting the number of search sessions received to generate first search session number information, and counting the number of search sessions for which a second search query was received per time interval with reference to the database for a second search session. Generating number information, referring to the database for each time interval; Generating third search session number information by counting the number of search sessions in which the first search query and the second search query have been received, using the first search session number information and the third search session number information Generating conditional probability information, and performing correlation using the total search session number information, the first search session number information, the second search session number information, and the third search session number information. ) Generating information, and determining whether the first search query and the second search query are related to each other based on the conditional probability information and the correlation information.;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.
