Embodiment Construction

[0019] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. In the interest of clarity and conciseness, not all features of an actual implementation are described in this specification. It should be appreciated, however, that in developing any such practical implementation, many implementation-specific decisions must be made in order to achieve the developer's specific goals, such as compliance with those constraints associated with the syntax analysis method, and the Restrictions may vary from implementation to implementation. Moreover, it should also be understood that development work, while potentially complex and time-consuming, would at least be a routine undertaking for those skilled in the art having the benefit of this disclosure.

[0020] Here, it should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only the device structure and / or processing steps clos...

Abstract

The invention relates to the technical field of natural language processing, in particular to a Chinese syntax analysis method and device based on punctuation processing. The method includes: researching Chinese punctuation marks and the syntactic and formal features of clauses, and classifying them; according to the features, compiling a digestion rule table; according to the hierarchical relationship between punctuation marks and clauses, converting the original input sentence into A series of tags to generate a tag table; according to the level and level of the tag in the tag table, perform syntax analysis and subtree splicing, and call the resolution rule during the analysis and splicing process. Compared with the one-pass analysis method that does not consider punctuation marks and the analysis method that uses punctuation marks to decompose long sentences, this method makes the level of syntactic analysis clearer, makes full use of the grammatical and semantic information of punctuation marks, and improves the efficiency of syntactic analysis and accuracy, and can solve the problem of nested use of punctuation marks very easily and clearly, without exhausting all combinations of punctuation marks.

Description

technical field [0001] The invention relates to the technical field of natural language processing, in particular to a Chinese syntax analysis method and device based on punctuation processing. Background technique [0002] Syntactic analysis is one of the core technologies of natural language processing and the basis for in-depth understanding of language, while natural language understanding is the basis of many language processing technologies such as machine translation, information extraction, and semantic retrieval. Therefore, syntactic analysis is an indispensable core and basic technology for Chinese information processing. [0003] Punctuation marks are an important part of written Chinese, and most of the existing automatic syntax analysis systems ignore their role. The paper "Hierarchical Chinese Long Sentence Syntax Analysis Method Introducing Punctuation Processing" (Li Xing, Zong Chengqing, Chinese Journal of Information, Volume 20, Issue 4) pointed out that i...
