本课题主要研究的是本体在医学常见病中的应用,利用本体的思想创建医学常见病的知识结构并介绍了本课题的研究背景、研究现状、理论基础并给出了系统的设计和实现。首先建立医学常见病本体和医生本体的主要架构,定义相关本体的属性,并描述这些属性和本体之间的联系,然后利用网络爬虫技术把Web上获取的相关疾病知识存入到数据库中。在以上基础上完成常见病管理系统的设计和实现,主要功能包括在线增加、删除、修改、查询医学常见病知识,在线增加,删除,修改,查询医生的相关信息。最后在eclipse开发平台上,利用浏览器和数据库MySQL完成系统的各项功能。 毕业论文关键字:本体; 常见病知识库; 网络爬虫。
Abstract With the consistent development of the Internet, ontology has been continuously studied and developed in all aspects。 The concept of ontology originates from the philosophical field。 Aristotle, the ancient Greek philosopher, defined ontology as the science of "existence"。 1990s to the present, the ontology has been applied to people’s living and learning。
The thesis mainly studies the application of ontology in the medical common diseases, and how to create knowledge base of medical common diseases by using ontology。 This paper introduces the background and status of the research, the theoretical basis, and the design and implementation of the system。 At first, this paper establishes the main framework of medical common disease and doctor ontology, defines the attributes of the related ontology, and describes the relationship between these attributes and ontology。 And then, this paper uses the technology of web crawler to deposit the related disease knowledge acquired from Web into the database。 On the basis of above to complete the design and implementation of the common diseases management system that the main functions including adding, deleting, changing, and checking the medical knowledge of common diseases and the relevant information of the doctor online。 Finally, at the eclipse development platform, using the browser and database MySQL to complete the functions of the system。
Keywords: ontology; common diseases knowledge base; web crawler;
