| 摘 要： | 传统的语料检索的不足主要为：（1）无法模糊匹配检索；（2）存在跨行词问题，无法保证查全率；（3）难以对检索结果缩检和扩检．为了克服这些不足，该文提出了基于RoughSet批处理汉语语料的词句．根据RoughSet和汉语语料的特征，给出了模糊检索算法（AMTRT）．通过与单汉字索引检索算法比较验证了AMTRT的有效性．AMTRT在实现各种模糊匹配，节省空间开销且不降低精确匹配查准率基础上，将词句的查全率提高近50％．

| Abstract: | The main deficiency of the traditional methods in Chinese corpuses retrieval are as follows: 1) Can't solve fuzzy-match retrieval;2) Can't guarantee to find the phrase that consists of words in two lines;3) It is difficult to compress or extend retrieval based on the retrieval result.To solve the problem,this paper makes following contributions: 1) Propose words of batch disposal of Chinese corpuses system based on Rough Set;2) Propose the retrieval algorithm of Ambiguous Multi-retrieval in Text Base on Rough Set Technique(AMTRT);3) The results show that the AMTRT method increases the rate of thorough inquiry by 50% without reducing the rate of accurate inquiry as against the traditional methods. |
