Abstract

The invention relates to an illegal online commodity detection method, comprising the following steps: step (1) of taking information of a page on which to-be-detected commodities exist through a web crawler; step (2) of finding a least-depth node comprising a plurality of information blocks with similar structure in a webpage as a critical node through analyzing a DOM (document object model) tree structure of an electronic commerce website on which to-be-detected commodities exist, forming an associated information point to extract and establishing a template, and extracting commodity attribute information data from webpage information acquired by the crawler; step (3) of establishing a semantic dictionary, performing word segmentation to the extracted commodity attribute information through a method based on character matching; step (4) of manually establishing an illegal semantic library, recognizing and judging words in the illegal semantic library and content words field related to the commodity attribute information processed through word segmentation according to a function Illegal List, and judging an illegal class of the illegal online commodity according to a function return result. The method provided by the invention is characterized by simple calculation and good timeliness, and is suitable for changeful page modes.
