【摘要】 Web2.0时代,随着互联网技术的飞速发展,网络资源资源呈几何式增长,信息量暴增的同时也导致用户在网络上获取资源的难度增大,基于关键词的信息查询技术和信息组织方式已不能满足用户需要。在此情况下,作为一种新的信息组织方式,没有语言限制、可以由用户自由添加的大众分类法应运而生,受到广大用户的青睐。但标签也存在着结构扁平没有等级层次,容易导致歧义等问题,为解决这此问题,面向计算机的语义检索和本体就被研究者提出,希望能够建立本体模型对知识进行描述,同时使知识能够被计算机理解和处理,从而实现资源在互联网的共享与交互。本体(Ontology)是一种框架,能在语义和知识层次上对具体应用领域概念模型进行描述,对解决应用领域知识的共享与交互有重要作用。但当前的本体研究和构建多是基于某个具体的应用领域,在本体构建方面并没有一个统一的标准,一个领域的本体构建方法被用于另一个领域,构建出来的本体应用性可能会较差,不能使本体集成的优势得到充分发挥。因此,本体构建方法研究和本体实际应用研究就具有很重要的意义。本文在已有本体构建方法的基础上,在信息检索领域结合用户对《白鹿原》的实际需求,采用了一种改进的本体构建方法,即将七步法与用户实际需求相结合的方法。在此方法指导下,以用户语义检索为应用需求,构建了《白鹿原》著作本体并进行应用的实例验证,从而实现用户对《白鹿原》相关知识的快速查询。更多还原

【Abstract】 With the rapid development of Internet technology and exponential growth of the network resources during the Web2.0era, it became more difficult for user to access the resources on the network. With the base of keyword information search and information organization approaches had failed to meet users’ needs. In this case, the Folksonomy has come into being by the majority of users of all ages as a new information organization with no language restrictions and can be added freely. At the same time, the Tag still has the problems as structure flat or with no grade level, in order to solve this problem, the computer-oriented semantic retrieval and ontology were easily supposed by researchers, hope to establish ontology model to describe knowledge, while the knowledge computer can be understood and processed in order to achieve resource sharing and interaction on the Internet.Ontology is the semantics and the level of knowledge on issues related to the conceptual model specific applications described framework has an important role to solve the application domain knowledge sharing and interaction. But the current ontology of research and construction are mostly based on the specific application areas, and there is no single standard in ontology construction, one ontology construction method was used in another area, the ontology’s application may be structured poorly, or the ontology integration advantages couldn’t run fully. Therefore, the Ontology Construction Methods and body practical application research has a very important significance.Based on the existing ontology construction method, and combined with the actual needs of users of the "White Deer Plant", this article used the method of combining the forthcoming seven-step method and the actual needs of users. In this method, under the guidance of the user semantic retrieval application requirements, the article build the framework of the "White Deer Plant" writings and application verified in order to achieve fast knowledge query of the "White Deer Plant".更多还原
