摘　　要：本文首先分析基于关键词的搜索的困难(查询串的表达不忠和表达差异等),说明基于语义的搜索的必要性。接着,尝试通过对"意义"和"意义相同"的某种可操作的限制,来发展一种基于语义的扩充式关键词搜索方式:通过同义表达形式来抓住查询串的"意义",并生成更多的检索串进行并发搜索。最后,规划怎样对汉语有关的同义表达进行全面深入的研究,并总结出若干识别查询串的同义形式的启发式规则。This paper firstly shows the necessity of meaning-based search by analyzing the constraints of keyword-based search, i.e., query strings are unfaithful to query intention and multiply divergent expressions are used to express a query intention. Then through setting some technical restrictions on ＂meaning＂ and ＂same meaning＂, it proposes a meaning-driven and generalized keyword-based search approach： constructing synonymous expressions to capture the meaning of a given query string and generate multiply query strings for simultaneous search. Finally, it illustrates how to investigate the Chinese synonymous expressions comprehensively, and extract some heuristic rules for recognizing the synonymous forms of a given query string.
