METHOD FOR CONSTRUCTING QUERY INDEX DATABASE, METHOD FOR RECOMMENDING QUERY BY USING THE QUERY INDEX DATABASE

摘要

PURPOSE: A method for constructing a query index database, a method for recommending a query by using the query index database are provided to classify a click document based on a query and click log of a user, thereby classifying and indexing a query language by a concern subject. CONSTITUTION: A representative query language and iso-form query language are selected by normalizing query log data(S403). The data with a clicked document and the query language corresponding to a click log data uses one of machine study-based classification among a naive Bayesian model, a SVM(Support Vector Machine) and a neural network and is classified by a relevant subject(S405). The representative query language and iso-form query language are indexed and saved with information about the relevant subject. Query language which frequency is the highest among query language log data having same URL(Uniform Resource Locator) is selected as the representative query language.
