摘要:

传统的基于关键词的信息查询方法已经不能满足用户的需要. 为此,提出基于语义逼近的信
息查询方法,探讨了语义替换规则和基于逼近度的查询结果排序策略. 最后基于多代理技术
实现了一个分布式语义查询系统,能执行跨多个本体的语义查询任务. 

关键词: 语义逼近, 语义查询, 本体, 多代理系统

Abstract:

According to that the traditional keyword based information query cannot satisfy
the users’ needs, a new approach for semantic query is proposed. Semantic subst
itution rules and ranking strategy based on semantic approximation degree
also are exploited. Also a distributed semantic query system (DSQ) is developed
to perform the tasks of semantic queries across multiple ontologisms based on a
multiagent system. 

Key words: semantic approximation, semantic query, ontology, multiagent system
