数据库汉语查询语言的分词研究与实现

The Study and Realization of Word Segmentation of Database Chinese Query Language

在综合考虑数据库查询这一特殊性的基础上，根据查询语句中词汇对数据查询不同贡献程度分级建立分词词典；然后提出了分步－－正向单扫描的分词方法（ＤＳＷＳ），并对该分词方法的时间复杂度进行了分析。

We think over the specials of data retrieving,and build word segmentation dictionaries based on the lexicons of data retrieve;Then we propose the Different step--Single scan Word Segmentation(DSWS),and analyze the time complexity of the segmentation algorithm.It is useful of this word segmentation based on language environment in disambiguation and word segmentation efficiency.
