中文摘要：

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．

英文摘要：

According to that the traditional keyword based information query cannot satisfy the users＇ needs, a new approach for semantic query is proposed. Semantic substitution rules and ranking strategy 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.
