摘要
中文分词算法是中文自然语言理解的基础,文章运用C#语言实现了正向、逆向、最长词、最短词的分词算法,通过大量样本实例分析,对不同算法进行了比较,介绍了分词算法在新词发现、歧义发现中的应用,重点阐述了关系型数据库、文本文件等不同数据结构的数据词典对中文分词算法速度的影响,创新性地引入一种非常规的数据词典索引表,大大提升了分词算法的速度。
Chinese word segmentation algorithm is the basis of Chinese natural language understanding.This paper uses C# language to realize the forward,reverse,longest and shortest word segmentation algorithms.Through the analysis of a large number of sample examples,this paper compares different algorithms,introduces the application of word segmentation algorithm in new word discovery and ambiguity discovery,and focuses on the impact of data dictionaries with different data structures such as relational databases and text files on the speed of Chinese word segmentation algorithm,an unconventional data dictionary index table is innovatively introduced,which greatly improves the speed of word segmentation algorithm.
