Embodiment 1

[0044] Embodiment 1: as Figure 1-2 As shown, a Thai sentence segmentation method based on maximum entropy classification model and Thai grammar rule correction, the specific steps of the method are as follows:

[0045] Step1. Collect and preprocess the Thai sentence segmentation corpus to construct a Thai text corpus; perform Thai word segmentation and part-of-speech tagging on the Thai text corpus, and construct a structured Thai text corpus required for Thai sentence segmentation research;

[0046] Step1.1. Use web crawler technology to collect Thai texts of Thai news and e-books from the Internet, and perform preprocessing operations on the obtained Thai texts to filter, deduplicate and denoise, thereby constructing a Thai text corpus;

[0047] Step1.2. Use the Thai word segmentation tool and Thai part-of-speech tagging tool to perform Thai word segmentation and part-of-speech tagging on the Thai text corpus, and perform manual proofreading to build a structured Thai text ...

Abstract

The invention relates to a maximum entropy classification model and Thai grammar rule correction-based Thai sentence segmentation method, and belongs to the technical field of natural language processing. The method achieves a very good classification effect for classification of space characters in a Thai language, and achieves a good promotion effect for research work of Thai sentence segmentation and Thai sentence boundary identification; the method achieves a very good sentence segmentation effect for Thai sentence segmentation research, and provides powerful support for research work of machine translation, named entity identification, sentence similarity calculation, a large corpus library quick construction technology, information extraction, information retrieval and the like.

Description

technical field [0001] The invention relates to a Thai sentence segmentation method based on a maximum entropy classification model and Thai grammar rule correction, belonging to the technical field of natural language processing. Background technique [0002] Thai sentence segmentation is the basis of Thai natural language processing research work. Most of the research results of natural language processing require the input or output of the language to be sentences rather than entire paragraphs, for example, research on machine translation, named entity recognition, sentence similarity calculation, and rapid construction of large corpus technologies. Sentence segmentation research in natural language processing research can be divided into two aspects, one is to identify sentence-end boundaries in languages ​​that lack sentence-end marks or weak sentence-end marks, such as Uyghur, Tibetan and Thai, etc.; the other One aspect is to disambiguate the sentence-end boundary re...
