Abstract

The invention discloses a keyword classifying method and a keyword classifying device. The keyword classifying method comprises the following steps: dividing a keyword to obtain morphological components of the keyword; extracting a plurality of morphological elements from the morphological components; inquiring a preset class to which each morphological element belongs so as to obtain a plurality of attribution classes; calculating the probability of each attribution class so as to obtain a plurality of attribution probabilities; determining the class represented by the maximum probability in the attribution probabilities as the class of the keyword. Through the keyword classifying method and the keyword classifying device, the problem that in the prior art, the precision for determining the class of the keyword is relatively low is solved, so that the effect of improving the accuracy for determining the class of the keyword is further realized.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a keyword classification method and device. Background technique [0002] Search engine keywords are keywords that users enter when using a search engine. Each keyword represents a need of the user. The classification of massive user keywords helps to analyze the demand distribution of groups. There are two existing search keyword classification methods, one is based on access path, and the other is based on form. [0003] The classification method based on the access path is based on an assumption that the keywords of queries (Query) initiated many times in the search engine are similar. The specific method is to record all the query keywords of the user in a session (Session), record the related words of each keyword and the frequency of co-occurrence in a session, repeat the statistics of related keywords for all sessions, and finally realize clustering. [0004] The...
