结合粗糙集与模糊集理论,提出一种信息检索的新方法。该方法首先对已知文本信息按关键词进行模糊聚类;然后利用粗糙集理论求出各关键词的重要性程度;最后根据最大相似度原则对文本信息进行检索,若结果集中文本数量较大,则按文本与已知文本的相似度从高到低进行排序,先返回相似度较高的相关文档。

Combining rough set and fuzzy settheory, a new method of information retrieval is put forward. Firstly, the text information is classified according to the key words based on fuzzy set theory. Then, the information is retrieved according to the maximum similarity degree principle. If the retrieval results are in larger quantities, the retrieval texts are ranked according to the similarity degree from high to low, and output the text information with higher similarity degree. At the same time, the authors adopt the comprehensive weighted similarity measure to reflect the different users of the ...
