本体论在公安案情理解中的研究与应用
发布时间：2018-11-27 14:16
【摘要】： 本体(Ontology)的概念起源于哲学领域，20世纪90年代以来，人们将本体的概念引入人工智能、知识工程和检索领域，从而使本体概念的内涵也随之发生了变化，在这些领域中，本体研究是关于知识概念表示和知识组织体系方面的研究。本体通常是指一套有关某一学科或某一领域的术语词表，以及术语之间关系的规范和说明。近年来，关于本体的研究与应用呈现出加速度发展的趋势，基础理论更为完善，应用领域更为广泛，技术产品更为成熟．与国外涌现的研究项目和研究成果相比，国内关于本体的研究尚存在较大差距，国内关于本体应用的研究尚处于起步阶段，尚未见到有关国内构建具有推理功能的学科或领域本体系统的报导。 本课题以公安执法领域中描述案情的中文文本为研究对象，探讨采用自然语言理解中的文本分类方法，实现根据文本的内容来判别文本类别，，给出相应的法律建议。首先在对语义检索部分，我们提出了最短匹配算法，针对检索的结果采用了一种基于本体的语义信息检索模型，避免了传统向量空问模型在语义处理方面的缺陷。根据不同关键字之间的组合利用本体的推理机制，采用Jena开发包作为起推理工具。利用不同关键字之间的语义关联等方面来充分考虑，得到与每个涉案人员相关一些的相关法律条款。并初步构建了一个公安法律文本自动分类系统。
[Abstract]:The concept of ontology (Ontology) originated in the field of philosophy. Since 1990s, people have introduced the concept of ontology into the fields of artificial intelligence, knowledge engineering and retrieval. Ontology research is about knowledge concept representation and knowledge organization system. Noumenon usually refers to a set of glossary of terms relating to a discipline or field, as well as the specification and explanation of the relationship between terms. In recent years, the research and application of ontology show the trend of acceleration development, the basic theory is more perfect, the application field is wider, the technology product is more mature. There is still a big gap in the research of ontology in China, and the research on ontology application is still in its infancy. There is no report on the construction of ontology system with reasoning function in China. Taking the Chinese text describing the case in the field of public security law enforcement as the research object, this paper discusses the method of text classification in natural language understanding, realizes the classification of the text according to the content of the text, and gives the corresponding legal advice. In the part of semantic retrieval, we propose the shortest matching algorithm, and adopt an ontology based semantic information retrieval model to avoid the defects of the traditional vector space query model in semantic processing. According to the combination of different keywords, using the reasoning mechanism of ontology, the Jena development kit is used as the reasoning tool. By taking full account of the semantic correlation between different keywords, we can get some relevant legal provisions related to each person involved in the case. And has constructed a public security law text automatic classification system preliminarily.
