摘　　要：介绍一种基于本体的非结构化信息访问机制,为现有系统应用中的非结构化信息提取提供统一的语义级解决方案。该方案克服了目前基于关键词检索方法所引起的信息冗余和信息不足,提供更为合理且更符合人们思维的查询方法与结果,从而有效地提高系统性能及其实际应用价值。介绍了该信息访问机制的整体框架,并重点介绍了信息访问语言FL-Plus、推理引擎及优化算法的实现。This paper introduces an XML information retrieval and optimizing mechanism based on the ontology. The mechanism provides an uniform semantic level scheme for unstructured information query in the application systems which are in existence, and it overcomes the insufficiency of information overloading and missing caused by the keyword-based retrieval, so it conforms to the custom of human thought more closely, and the results become more rational and useful. This mechanism can promote the capability of application systems and improve them application value. It first introduces the general framework of the mechanism, and then the information retrieval language FL-Plus, search engine and optimization algorithm.
