【摘要】 内容分析法是一种对文献内容进行系统地、客观地、定量地描述的研究方法,并且在社会科学研究中得到了广泛的使用。它作为一种定量与定性相结合的研究方法,在不同的领域中具有不同的应用功效。它可以得到内容的本质,查明某个专题多年来的客观事实和发展趋势,描绘学术发展的轨迹,阐述学术发展的历程,发现作者的风格,反映个人或团体的态度、兴趣,获取政治、军事、经济情报等一系列隐含在内容中的潜在信息。但是,随着信息的激增,以及语义网的发展,人们对内容分析有了新的要求,要求对内容在语义层次上进行分析,也就是迫切要求内容分析法在新的需求环境下获得新的拓展。本体(Ontology)是共享概念模型的明确形式化规范说明。它关注概念之间的内在的语义联系,是语义检索的基础。 本文首先研究了内容分析法的基本理论、应用与局限性,在对本体的基本原理进行阐述的基础上,提出了将内容分析法与本体进行有效结合的新的研究思路,然后探索了基于Ontology的内容分析法的操作流程和应用价值,提出了基于Ontology的内容分析系统的基本架构与层次。最后,根据本文提出的一套新的操作程序,根据内容分析的实例,开发了一个基于Ontology的内容分析模拟系统并实现了部分功能。更多还原

【Abstract】 The method of content analysis is a research technique that can give a systematic, objective and quantitative description to literature content, and it has been widely used in social science researches. As a research method that combined quantitative and qualitative techniques, it has different effects in different fields. Using this method, people can get the essence of the content, find the objective fact and development trend of any special topic, describe the development track of science, illustrate the development course of science, discover the style of author, reflect the attitudes and interests of individuals and communities, and acquire the a series of underlying information such as political, military, economic intelligence and so on. However, with the blast of the information and the development of the semantic web, people make a new request to content analysis, which is analysis on the semantic level. So, under the new requirement, the method of content analysis is urgently called for development. Ontology is a formal specification of a shared conceptualization. It cares about the internal relations between concepts, which is the base of semantic retrieval.This paper studies the basic theories and the applications of the method of content analysis, and discusses its limitations. By investigating the principle of ontology, the method of content analysis and ontology are integrated into a new research technique. Then probes into the operation and the value of application of the method of content analysis based on ontology, and puts forward the basic framework and hierarchy of this new method. At last, according to the operation flow, a simulative system for content analysis based on ontology is built associating with the instance of content analysis.更多还原
