摘要中文分词是中文信息处理的前提,随着计算机及网络技术的发展,中文分词的应用也越来越广泛。目前中文分词算法主要分词三大类:基于词典的分词方法、基于理解的分词方法和基于统计的分词方法。本研究以网络教学系统中的智能答疑子系统为平台,对智能答疑模块中的中文分词技术进行研究分析,并在智能答疑系统中实现了三种基于词典的分词方法:正向最大分词法、逆向最大分词法和最少分词法,完善了原有的答疑系统,提高了答疑的准确率。本文具体描述了这三种分词算法,并给出其在智能答疑系统中的实现方法。64531

Title Intelligent Network Teaching and Learning System—the Design and Development of Intelligent Answering subsystem
Abstract
Chinese word segmentation is the basis of Chinese information processing. With the development of computer and network technology, Chinese word segmentation is becoming more and more widely applied. Chinese word segmentation algorithm is mainly in three categories: dictionary-based method, semantic-based method and statistic-based method. This research is based on the platform of the intelligent answering subsystem in the network teaching system. It analyzes the Chinese word segmentation technology applied in the intelligent answering module, and implements three dictionary-based methods: forward maximum matching method, backward maximum matching method and fewest words matching method in the system. It improves the original question-answering system and the accuracy of the answers to the questions. This paper describes the three segmentation method in detail, and indicates their implementations in the intelligent answering system.
