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 present invention relates to the technical field of natural language processing, and particularly to a punctuation mark processing based Chinese syntax analysis method and apparatus. The method comprises: studying Chinese punctuation marks and syntax and formal features of clauses, and hierarchically layering the Chinese punctuation marks and the syntax and the formal features of the clauses; according to the features, preparing a resolution rule table; according to hierarchical level relationships of the punctuation marks and the clauses, transforming an original input sentence into a series of tags, and generating a tag table; and according to hierarchies and levels of the tags in the tag table, performing syntax analysis and subtree splicing, and calling a resolution rule in the analysis and splicing process. Compared with a one-pass analysis method without consideration into the punctuation marks and an analysis method of decomposing a long sentence by using the punctuation marks, the method makes the hierarchies of the syntactic analysis more distinct, and makes full use of grammatical and semantic information of the punctuation marks, so that efficiency and accuracy of syntactic analysis are improved, and the problem of nestedly using the punctuation marks can be very simply, conveniently and distinctly solved, without exhausting all punctuation mark combination usages.

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...
