Abstract

The invention relates to the technical field of computers and discloses a product key word extraction method and device. The method is implemented by steps: extracting features of a target tile of a to-be-extracted product key word; inputting the features into a preset module in a preset feature combination manner to acquire a state function corresponding to the feature combination and a weight related to the state function; adopting a preset algorithm for operation according to the state function and the weight related to the state function, and extracting the product key word of the target tile according to an operation result. Therefore, automatic product key word extraction can be realized, product key words of hundreds of millions of commodities can be extracted accurately in a standard and objective manner, product key word extraction manpower and time cost can be saved, and accuracy and comprehensiveness of the product key words can be improved while the recognition recall rateis increased.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for extracting central product words. Background technique [0002] With the rapid development of e-commerce, online shopping has provided great convenience for people's life and work. When a user performs a product search query, the search engine often provides the user with the product most relevant to the search keyword according to the input search keyword. Composition analysis of product titles is the core problem of solving search relevance, and has a wide range of applications in many fields such as personalization and recommendation. Different from general documents, commodity titles in the field of e-commerce are usually piled up with several words, which undoubtedly increases the technical difficulty in accurately identifying commodity components. [0003] An important link in the analysis of commodity title components is the identification of ce...
