Abstract

The application provides an object statement based dependency syntax analysis method and apparatus and a server. The method comprises: obtaining a target word sequence of a to-be-analyzed target statement; by taking first two target words in the target word sequence as current target words, judging whether the current target words are backbone words or not, if so, determining a dependency relationship between the two target words by adopting a preset action prediction backbone model, and if one or two of the two target words are not the backbone words, determining the dependency relationship between the two target words by adopting a preset action prediction complete model; and obtaining next two to-be-processed target words as the current target words by reference to a statement forming sequence of the target word sequence and the determined dependency relationship, and performing the step of judging whether the current target words are all the backbone words or not until all target words in the target word sequence are all analyzed. According to embodiments of the application, the influence of incorrect cascading on accuracy can be greatly reduced, so that the accuracy of dependency syntax analysis results is improved.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a method, device and server for dependency syntax analysis of target sentences. Background technique [0002] Today, with the Internet becoming more and more developed, using computers for language recognition and processing is already a very mature technology. Syntactic analysis is a research content of computational linguistics (Computational Linguistics). It establishes a formalized mathematical model, designs an effective algorithm, uses a computer to analyze and process sentences, and converts them from a word sequence form to a syntax tree form to capture sentences. Internal structure and collocation relationship between words. In the field of Natural Language Processing (NLP, Natural Language Processing), two mainstream syntax systems are mainly analyzed, namely Phrase-structure Grammar and Dependency Grammar. [0003] Dependency syntax was proposed by ...
