Abstract

The invention relates to the field of e-commerce, and discloses a method of intention entity recognition based on a user query log. The method comprises steps: an original log is analyzed and extracted, and a session query set, a common click query set and a common query commodity set are formed; through processing, mutual disjoint subsets (I, Q) are obtained, a bipartite graph is built through a click relation, and word clustering is carried out; according to a word clustering result, segment processing is carried out on each query word, and multiple segments are obtained; and weight calculation is carried out on the segments, weight scores of the segments are further obtained, and a segment with the highest score serves as the corresponding entity of the query word. Through analyzing the original log, the query word is subjected to word clustering and weight analysis, intention entity recognition is realized, a context and a semantic context are blended, the query accuracy is improved, better intention recognition effects are achieved, and the online calculation overhead is saved.

Description

technical field [0001] The present invention relates to the field of electronic commerce, in particular to a method for identifying intent entities based on user search logs. Background technique [0002] In the era of the prevalence of the Internet, people's shopping methods have gradually changed from shopping in physical stores to purchasing on e-commerce websites. This change in mode not only provides people with greater choice space, but also provides people with a more convenient shopping experience. . At present, because different users are affected by factors such as education, culture, and region, the query words entered may vary greatly when expressing the same product. Therefore, it is necessary to perform intent entity recognition on the query words. [0003] In the existing intentional entity recognition model, the machine learning method is used to manually mark the learning samples, train the entity recognition model, mark the query words, and then get the co...
