最大相关模糊查询及其应用研究

The Study of Maximum Coherence Inquiry and Application

在文档类模糊查询方面进行了较深入的研究,首次提出并实现了间接相关全衰期和最大相关查询,其原理有别于传统字符串相等比率的模糊查询技术,采用相关性定义及最大相关传递模式,目的在于实现更广泛意义下的模糊查询。在适当定义相关度情形下,不但能够查找出传统模糊查询搜索到的内容,而且可以查找到字面上完全不同但意思相关的条文,最大相关传递模式能够使得词语之间的相关度按一定规则传递,因此更具一般性和实用性。

In this paper, the author deeply studied the fuzzy inquiry in document management, and originally brought forward and realized the total-life and the maximum coherence inquiry. It is completely different from the traditional fuzzy inquiry technique which is based on string comparing ratio, and applies coherence definition and the model of maximum coherence transmission, it aims at the fuzzy inquiry under a broader significance. If the coherence is defined properly, it can search out the clauses which are totally distinct in text but obviously relevant in meaning. The maximum coherence transmission model can make it possible that the coherences between words will pass over under a certain rule, therefore it is more general and practical.
