基于辞典的相似匹配

Similarity Measurement Based on Thesaurus

在开发基于知识系统过程中,经常要进行字符型特征的相似匹配,使用基于关键词的匹配方法会出现匹配不全或匹配错误的现象.针对这一问题,以材料特征对飞机装配工艺知识的影响为对象,研究字符的概念相似匹配,提出一种基于辞典的知识相似匹配.研究辞典的构建,给出知识匹配辞典的模型,并基于辞典模型,设计了知识的相似匹配算法.

During the course of developing knowledge based systems, the similarity measurement of char data type feature is often employed, and using the measurement based on keywords, the omittance and inaccuracy of measurement is occurred. To resolve this problem, taking the material feature＇s effect on similarity measurement of aircraft assembly process planning knowledge as an example, the conceptual similarity measurement of character is researched and a kind of similarity measurement based on thesaurus is proposed. The configuration of thesaurus is researched and a model of measurement thesaurus is given. The similarity measurement algorithm based on thesaurus is developed.
