基于知识的心电图自动诊断系统的设计

介绍了基于知识的心电图自动诊断系统的系统构成及设计过程中采用的关键技术.模拟了现实世界心电专家根据心电图进行诊断的思维方式,揉进了可能性理论和模糊理论的概念,同时又避免了复杂的推理过程.其心电图病理数据库由知识库和规则库两部分组成,采用数据库形式存储.推理诊断系统采用数据驱动的正向推理结合基于CF模型的不精确推理.推理诊断系统与知识库和规则库的实际存储内容没有必然联系,所以适用于诊断型的专家系统.

Knowledge-based ECG Automatic Diagnosis System

This paper presents the structure of a knowledge-based ECG automaticdiagnosis system and the key technologies applied in the system. Using database technology to store, the ECG knowledge-database is constituted of ECG knowledgeand a set of rules .The inference engine of the system simulates the real diagnosis of the experts and combines the forward reasoning with inexact reasoning. At the same time, complicated reasoning is avoided. Because the inference engine is independent of what is stored in the ECG knowledge-database, the system is suitable for expert system.
