【摘要】 本论文是对作者毕业课题研究的一次全面论述和介绍，论文首先介绍了课题的研究背景以及论文的结构。Internet已经成为当今和未来人们获取所需资源和信息交流的主要场所，随之而来的就是网页资料呈几何级数爆炸性增长，但是由于网页的无结构性、超链接的自由无序、以及网页内容的海量性、多样性和动态变化，人们要搜索到真正想要的信息不太容易。为了让网页发挥更大的潜能，万维网之父Berners-Lee于2000年在XML2000的会议上正式提出了语义网(Semantic Web)，而本体位于由文档描述到推理论证的层次，因此本体是实现语义网的关键层。本论文系统介绍了本体和语义网的理论和相关技术。在该理论的指导下，运用相关技术构建了旅游领域的本体。在领域本体的构建过程中，采用了本体描述语言OWL作为编写语言，使用protégé3.1构建目标领域的领域本体。本论文重点研究了基于本体语义网的检索，通过Jena设计了旅游领域的简单的检索模型。本论文的研究意义在与将本体的概念引入到实际的应用层面，并结合检索研究，尝试了将这一新概念应用到实践中的效果。更多还原

【Abstract】 This thesis is a full description on author’s research subject. Firstly, the thesis introduces the research background and the structure. Internet has become the main way to get the resource and information exchange in the coming future, with the webpage are increasing explosive, users has to search the needed information in so vast information ocean, which be look like seeking a needle in ocean, this difficult problem has been resolved fitly by search engine technology, but because of no structure of web page, no order of surpassing linking, and great capacity and diversity and development change of web page, the users would be not so search for the necessary. For web page brings bigger latent energy, Berners-Lee, father of World Wide Web, has brought forward a semantic net on the convention in Y2K in XML2000 formally, the ontology are located in the arrangement of ideas description that from document to reasoning demonstration, so the ontology is the key of realizing the semantic web.This thesis has introduced the theory and, relevance technology of ontology and semantic web, guided by that theory, then structured the travel domain ontology apply the relevance. In the process of structured, adopt OWL of the ontology description language was adopted to be writing language and the protégé3.1 of construct tool.It is important to study the semantic web retrieval based on ontology, and designed a simple retrieval model of the domain of travel by Jena.The research significance of this thesis is to introduce the concept of ontology to real application, together with the retrieval, and realize a mini-system based on ontology.更多还原
