Because of the Chinese syntax and semantic complexity, Chinese text-matching is very difficult. Therefore, designing an efficient and accurate non-structural text-matching system based on Chinese has a wide range of practical significance. 由于中文语法和语意的复杂性,使得中文的文本匹配变得异常困难,因此设计一个基于中文的高效、准确的非结构文本匹配系统具有广泛的现实意义。
Because of the deficiency of traditional information retrieval technology, the paper introduces the ontology technology, utilizes ontology to describe the domain knowledge and analysis user query at the same time, to achieve the semantic level query rather then text-matching based search. 针对传统信息查询技术的不足,本文引入本体技术,通过本体来描述打印机领域知识,同时对用户查询请求进行语义分析,实现语义层次上的而非传统的文本匹配的信息查询。
