Abstract

The present application discloses a method for constructing natural language word segmentation. The method includes: obtaining Ngram word segmentation of natural language, and discontinuously combining the Ngram word segmentation according to the sequence of positions to obtain the combined word segmentation. It can be seen that on the basis of the original Ngram word segmentation, the obtained Ngram word segmentation is combined according to the order of the position sequence. Through this method, the expressive ability of natural language is increased, and the classification accuracy of natural language is improved. Moreover, in this solution, the window size is further set for the combined word segmentation, so as to avoid generating too many combined word segmentation feature quantities, and improve the classification speed of natural language. Correspondingly, the present invention also discloses a natural language word segmentation construction system, a natural language classification method and system, which also have the above beneficial effects.

Description

technical field [0001] The invention relates to the field of natural language processing, in particular to a natural language word segmentation method and system, and a natural language classification method and system. Background technique [0002] With the development of science and technology, the Internet has become an important means for people to acquire knowledge. Among them, technologies such as information retrieval, text classification and man-machine dialogue have penetrated into all aspects of people's lives, and people have to use natural language processing more or less (Natural Language Processing, NLP) research results to obtain or mine all kinds of knowledge and information on the Internet, therefore, natural language processing has become one of the most popular subjects in this century. [0003] In natural language processing, a word is the smallest meaningful language component that can move independently, while Chinese uses a word as the basic writing un...
