毕业设计（论文）-基于网络的鱼病诊断知识获取系统设计.doc

摘要
鱼病诊断知识的构成比较复杂,既有定量的数值性知识,又有定性的描述性知识,如何有效地获取和管理这些知识关系到整个专家系统的运行效率和实用价值。本文以知识获取理论为指导,结合鱼病诊断知识的具体特点,从技术角度开发了一个基于网络的鱼病诊断知识获取系统。本系统主要包括鱼病诊断知识库和知识获取界面两部分。本系统通过友好的知识获取界面,以尽量自然的人机交互方式完成鱼病诊断知识由领域专家向知识库内部组织模式的转换与传递。鱼病专家经过简单的培训,就可以自主地通过知识获取系统方便快捷地向知识库中输入诊断知识。由于采用获取实际诊断中的病例建立知识库,诊断知识真实可靠,知识库的实用性强。而且本系统基于网络设计,可以进行实时信息交互,效率高。

Abstract
posing of fish disease diagnosis plex. The knowledge of fish disease diagnosis is not only about figure but also about description. It is significant to acquire and manage the knowledge effectively. And that affect the efficiency and practicality of the Expert System. After analyzing theory of Knowledge Acquisition and fish disease diagnosis, this paper describe a Web-Based Knowledge Acquisition System For Fish Disease Diagnosis. This system consist of two part, a Knowledge Base for fish disease diagnosis and an interface for Knowledge Acquisition of fish disease diagnosis. Through a friendly interface, this system can transform and transfer the knowledge of fish disease diagnosis from the expert on that to the Knowledge Base expediently. After an ordinary training, the expert on fish disease diagnosis can input the knowledge through the interface and the into the Knowledge Base easily and quickly. And the knowledge acquired is very actual and effective. For this Knowledge Acquisition system is Web-Based, expert municate with the Knowledge Base quickly and expediently.
Key Word: Fish Disease Diagnosis, Knowledge Acquisition, Knowledge Base, Web-Based
