【摘要】：学术期刊传播最新科技信息、促进学术交流,是科学技术工作的一个重要组成部分,既是科技工作者学术生命的一种体现,也是科学技术发展的历史记载。目前,随着信息资源的不断增多,期刊全文数据库已经成为获取文献信息的重要途径,同时,又存在期刊论文的检索如何与新技术接轨,提高查全、查准率,改善检索便利程度等的问题。本文从“语义检索”和“可视化”的角度,提出了一种基于本体的期刊论文语义检索和可视化导航的方案,将语义检索和可视化技术紧密结合,应用到期刊论文的检索中。绪论部分首先对本文的研究背景做了一个概要介绍,然后论述了本文的研究目的和意义,进而对语义检索和可视化问题的研究和应用现状进行了文献调研,最后介绍了本文的研究方法、技术路线和章节内容。第二章主要介绍了语义检索的理论、本体的概念、本体构建工具Protege、本体的分类以及基于本体的语义检索的关键技术,同时也从信息可视化的含义、方法及显示技术三个方面对信息可视化进行了较详细的介绍。第三章从用户需求的角度出发,以南京农业大学、南京航空航天大学、南京理工大学图书馆参考咨询人员以及在参考咨询部门实习的图书情报专业研究生为调查对象,开展系统需求调查,并根据调查分析结果指导系统的设计。第四章通过第三章对期刊论文语义检索与可视化导航系统需求的调查,以用户需求为导向,概要介绍了系统需求,设计原则,分析了用户操作流程、系统的功能、体系结构及数据库表结构的设计。第五章综合应用Protege构建了数字参考咨询领域的本体,利用开源工具包Jena进行语义查询推理；基于JAVA编程语言,结合语义检索与可视化技术构建了一个数字参考咨询领域期刊论文语义检索和可视化导航平台,并对该系统的开发思路和关键技术进行详尽的说明,最后将系统的结果依次展示。第六章介绍了系统测评指标的选择以及具体的测评情况分析。第七章对总体工作做了总结,指出本文开发的期刊论文语义检索与可视化导航系统存在的不足,并探讨了进一步的研究方向。
[Abstract]:The dissemination of the latest scientific and technological information and the promotion of academic exchange in academic journals are an important part of scientific and technological work. They are not only an embodiment of the scientific and technological workers' academic life, but also a historical record of the development of science and technology.At present, with the increasing of information resources, the periodical full-text database has become an important way to obtain literature information.The problem of improving retrieval facilities, etc.In this paper, from the point of view of "semantic retrieval" and "visualization", a method of ontology based semantic retrieval and visual navigation for periodical papers is proposed. The semantic retrieval and visualization technology are closely combined and applied to the retrieval of journal papers.In the introduction part, a brief introduction is made to the research background of this paper, and then the purpose and significance of this paper are discussed, and then the research and application of semantic retrieval and visualization are investigated.Finally, this paper introduces the research method, technical route and chapter content.The second chapter mainly introduces the theory of semantic retrieval, the concept of ontology, the ontology construction tool Protege, the classification of ontology and the key technology of ontology based semantic retrieval. At the same time, it also introduces the meaning of information visualization.The method and display technology of information visualization are introduced in detail.The third chapter, from the point of view of users' needs, takes Nanjing Agricultural University, Nanjing University of Aeronautics and Astronautics, Nanjing University of Science and Technology as reference consultant and library and information major graduate students in reference department as the objects of investigation.Carry out systematic requirement investigation and guide the design of the system according to the result of investigation and analysis.In the fourth chapter, through the investigation of the requirement of the semantic retrieval and visual navigation system of the periodical papers, the author introduces the system demand, the design principle, the user operation flow and the function of the system, taking the user demand as the direction.Design of architecture and database table structure.The fifth chapter synthetically uses Protege to construct the ontology of the digital reference service domain, uses the open source toolkit Jena to carry on the semantic query reasoning, based on the JAVA programming language,Combined with semantic retrieval and visualization technology, a platform for semantic retrieval and visual navigation of journal papers in the field of digital reference and consulting is constructed, and the development ideas and key technologies of the system are explained in detail.Finally, the results of the system are displayed in turn.The sixth chapter introduces the system evaluation index selection and specific evaluation analysis.The seventh chapter summarizes the overall work, points out the shortcomings of the semantic retrieval and visualization navigation system developed in this paper, and discusses the further research direction.
