【摘要】 在信息爆炸的时代,如何快、好、准地找出自己所需的信息非常关键。研究目前的校园网搜索系统,我们不难发现,由于检索提问式过于自由简单及单纯的字符匹配无法提供基于概念的智能搜索等原因,其在使用上存在如下两个关键弊端:查准率和查全率得不到保证;无法搜索提供网页上的隐藏信息。本研究从以本体论构建信息知识库的概念出发,将高校所有信息元进行标准化、层次化、关系化的描述,通过本体构造软件及构造语言初步建立教育信息本体知识库,并搭造高校语义搜索系统构架,为校园网语义搜索系统的完美实现打下了基础。在整个搜索系统中,信息库的信息元是搜索的本体,而信息元之间的逻辑关系则是进一步优化搜索的依据。相对综合性搜索而言,高校信息内容比较集中,信息元之间的关系也较为明确。基于本体管理的高校搜索系统将高校内所有的信息元及它们之间的逻辑关系用机器语言的形式完整的表述出来,再与搜索引擎连接,甚至是一种智能化的连接,这无疑将推动搜索的完整性和便捷性进入一个新的高度。更多还原

【Abstract】 In the time of information explosion, how to find the information witch we need quickly, high quality and accurately is very pivotal. Through the search of the university search engine which is in used, we can easily to find two pivotal disadvantages. One is that the veracity and the extension can not be insured. The other one is that we can not find the pocket information in the web. The reason of them is too easy question methods of the search engine and character matching only.The search begins from the concept of ontology. It described all the information of university in the methods of standardization, arrangement and connection. It set up the university information ontology with the help of the ontology construction software and ontology construction language. It set up the truss of the university web search engine system. It does the basic work to prepare for the perfect realization of the university web search engine.In the search engine system, the information date of the information store is ontology, and the logic relation between the information data is the reason to perfect the search engine. Compared with the traditional search engine, the content of the university information has more focus, and the relationship between the information data is also more clear. The university search engine described completely all the information data and the logic relation between them, and then ,it was combined with the search engine, even a wisdom connection. It would sure to push the university search engine up to a higher level.更多还原
