Abstract

The invention provides a keyword classification method. The method includes the following steps: obtaining keywords to be classified; inquiring whether keywords matched with the keywords to be classified exist in a pre-stored association table, on yes judgment, determining classification related to the keywords in the pre-stored association table as the classification of the keywords to be classified, and on no judgment, conducting the next step; selecting keywords similar to the keywords to be classified from the pre-stored association table; determining the similarity of classifications of the keywords to be classified and the selected keywords; according to the similarity of the classifications of the keywords to be classified and the selected keywords, determining the classification of the keywords to be classified. A keyword classification system for achieving the method is further provided. By means of the keyword classification method and system, keyword classification efficiency can be improved, response speed of the system is increased, and system operating amount is reduced.
