Abstract

The invention discloses a commodity attribute extraction method and a commodity attribute extraction system. The method comprises the steps: obtaining an original comment corpus; performing word segmentation and part-of-speech tagging on the original comment corpus; constructing a commodity attribute extraction template according to the word segmentation and part-of-speech tagging results and syntax mode characteristics; the commodity attribute extraction template is used for extracting commodity attributes in the original comment corpus on the basis of the commodity attribute extraction template and storing the extracted commodity attributes into a transaction file, and the commodity attributes comprise nouns, nouns phrases and verb phrases; scanning the transaction file by adopting an association rule to obtain a candidate commodity attribute set I0; filtering the candidate commodity attribute set I0 by adopting a filtering rule to obtain a candidate commodity attribute set I4; and clustering the candidate commodity attribute set I4 to obtain a final commodity attribute set I5. According to the invention, scientificity, integrity and convenience of commodity attribute extractioncan be realized.

Description
