Abstract

The invention relates to a maximum entropy based Vietnamese cross ambiguity elimination method and belongs to the technical field of natural language processing. The method comprises the steps of firstly performing disambiguation modeling on Vietnamese cross ambiguity field corpora in a formed Vietnamese cross ambiguity field library to obtain a Vietnamese maximum entropy cross ambiguity elimination model; and randomly selecting test corpora from the Vietnamese cross ambiguity field corpora and performing disambiguation through the established Vietnamese maximum entropy cross ambiguity elimination model to obtain a disambiguated parameter sequence. The method effectively eliminates the ambiguities of Vietnamese cross ambiguity words and provides powerful support for work such as lexical analysis, syntactic analysis, semantic analysis, information extraction, information retrieval, machine translation and the like; at present, no related Vietnamese cross ambiguity elimination reports are discovered; and the method achieves a very good effect.

Description

technical field [0001] The invention relates to a maximum entropy-based Vietnamese cross-ambiguity disambiguation method, which belongs to the technical field of natural language processing. Background technique [0002] Vietnamese ambiguity disambiguation is the main link in the work of word segmentation and part-of-speech tagging, and it is the basis of other high-level applications and plays an extremely important role. In various Vietnamese information processing software or systems, Vietnamese cross-ambiguity disambiguation is an indispensable work. With the continuous improvement of Internet search technology, disambiguation has attracted more and more attention. The degree of disambiguation of ambiguous fields determines the accuracy of search; at the same time, disambiguation can improve the lexical analysis, syntactic analysis, semantic analysis and Application effects such as machine translation. Ambiguity is divided into intersection ambiguity and combination am...
