【摘要】 被誉为下一代万维网发展蓝图的语义Web，期望为Web资源引入语义描述而被机器理解的设想，使利用本体提高网络智能化水平的研究很快成为计算机领域的发展前沿和关注热点。本文提出的语义Web环境下的领域本体研究，构想把语义Web理论研究与信息化建设相联系，实现为用户提供高等教育资讯智能化服务研究与试验的初期目标。这种把语义Web理论作为具体领域应用的研究方向，具有重要的理论价值和应用价值。文中主要分析了语义Web发展背景与体系结构；对基于XML语法的本体描述语言的发展进行探讨；对语义Web环境下的RDF(S)和OWL等本体描述语言进行研究，并在此基础上讨论了本体建设的方法论研究和本体建模处置原则；对描述逻辑基础与推理原理进行分析；提出了高校资讯信息系统的整体设计思路与考研资讯领域本体模型实现方案，对考研资讯领域本体创建试验、确认评价与语义信息抽取设计进行了系统研究分析讨论。本文将语义Web引入高等教育咨询领域，是教育信息化建设中技术创新的有益尝试。它从考研资讯信息服务系统整体设计方案要求出发，在初步实现领域本体的语义描述与模型创建的研究过程中，将为机器可理解的语义信息咨询智能化提供理论依据和试验模型经验。文中描述的领域本体建立与语义信息抽取设计虽然还不尽完善，但作为以后进化的基础因子，它已经初步构建出考研资讯领域核心本体的模型框架；其中的一些实例已可以为考研咨询者提供部分高校的主要资讯数据。在领域本体原型构建中遵循简单实用、不断进化的原型迭代方法建设策略，为有效降低领域本体建设过程对领域专家依赖度的可行性作出探索性的体验；通过对汉语分词及语义实体信息抽取技术设计的应用分析讨论，为进一步在语义Web环境下展开对领域本体应用研究的实践提供了试验性设计与技术路线本土化的参考思路。通过对语义Web研究成果与应用前景的深入分析描述，用多角度展现了国内外业界在语义Web领域的前沿发展和研究动态，对于语义Web及本体核心技术理论及应用的研究分析，将给初次接触语义Web技术的学习者提供较为系统的知识描述和学习基础，有利于在不同领域对语义Web技术应用的推广。语义Web环境下的领域本体技术在考研资讯咨询服务智能化应用的新颖性，其现实意义已超出课题研究的本身；尽管它只是一个规模不大的试验参考模型，但却包含了语义Web技术应用的基本原理和发展趋势。本文研究，深化了语义Web环境下的领域本体描述、建模与应用的理论和方法，对于在不同资讯领域实现咨询智能化服务的研究有所示例，具有一定的理论与实践意义。更多还原

【Abstract】 Semantic Web, reputed as blueprint of next generation World Wide Web development, is expected to introduce semantic description for Web resources, thus it could be understood by the machine. This tentative plan makes the research on Enhancing network intellectualization level by use of ontology quickly attract much attention and become the development frontier of the computer field.The paper presents research on Domain Ontology under Semantic Web environment, conceives the idea of associating the Semantic Web theory study with information construction, achieves initial target of providing users with research and test on intelligent serves in higher education information .Research of applying semantic Web theory into specific areas has important theoretical and practical value.The paper has mainly analyzed the semantic Web development background and the system structure; discussed the development of ontology description language based on the XML grammar; on the basis of researching in ontology description languages under semantic Web environment such as RDF(S) and OWL, we also discussed ontology construction methodology and ontology modeling disposal principle; analyzed description logic basis and reasoning principle; proposed overall design idea of the university information consulting system and realization plan of the graduate entrance examination consulting domain ontology model, and made systematical research and discussion on creating tests, confirming evaluation and design of semantic information extraction.The paper applies the semantic Web into higher education consulting field, it is really a useful attempt of technology innovation in educational information construction. It starts from overall design requirements of graduate entrance examination consulting information service system. In the process of initially realizing semantic description and model construction of domain ontology, it can provide the machinery understandable semantic intelligent information consulting with Theoretical basis and experimental model experience.The establishment of domain ontology and semantic information extraction design, while not perfect, but as a basic factor for the future evolution, it has initially built up model framework for the core ontology of the graduate entrance examination consulting domain; what’s more, some instances has been able to provide main consulting data of a few universities for the graduate entrance examination inquiries.In the construction of the domain ontology prototype, we followed iterative strategy of simple, practical and constant evolution, explored feasibility of effectively reducing dependence on the domain ontology experts; provided experimental design and referent idea of technical localization for practice in further applied research on domain ontology under semantic web environment through experience of technical design on Chinese word segmentation and semantic entity information extraction.The paper has displayed semantic Web research and development trends in both domestic and foreign industries from various angles, through deep analysis and description of research results and application future of semantic Web. Research and analysis in core technical theory and application of semantic Web and ontology will provide the primary learners with more systematic knowledge description and learning base. It is conducive to promote the use of semantic Web technology in different areas.The practical significance of intelligent application of domain ontology technology under semantic Web circumstance into graduate entrance examination information advisory services is beyond the research itself for its novelty; although it is just a small reference model, it contains the basic principles and trends of semantic Web technology.The paper has studied and deepened theory and methods of domain ontology description, modeling and application under semantic Web circumstance, it has theoretical and practical significance in research of intelligent advisory services in different IT fields.更多还原
