Abstract

The invention discloses a Chinese word segmentation method and device. The method comprises the steps of receiving first target text information sent by a user; carrying out data mapping on the firsttarget text information through a first classifier to obtain corresponding first target category information; and performing preset inquiry operation according to the first target category informationand returning an inquiry result to the user. In a mode that the first target text information sent by the user is subjected to the data mapping through the first classifier, the corresponding first target category information is obtained, so that the purpose of performing preset inquiry operation according to the first target category information is achieved, the technical effect of improving theword segmentation accuracy is achieved, and the problem of low accuracy of Chinese word segmentation in related technologies is solved.

Description

technical field [0001] This application relates to the field of search engines, in particular, to a Chinese word segmentation method and device. Background technique [0002] Search engines are based on a structure called an inverted index. The inverted index is a structure of <key, value>, and the key value in this structure directly affects the accuracy, recall rate, and speed of the entire search engine. Let's take a look at what happens if we don't use Chinese word segmentation. [0003] Assuming that Chinese word segmentation is not used, a single Chinese character index can be used. For example, for Daguan, the word 'Da' is first indexed, and then the word 'Guan' is indexed. Similarly, for an article, first index all Chinese characters separately and record their positions. In the search process, first find all the documents of the word 'Da', then find all the documents of the word 'Guan', and then do the cross 'AND' operation, that is, only the documents con...
