介绍了一个综合知识发现与知识求精系统一XFKDRS.它由分类规则、关联规则、序贯模式、相似模式、聚类模式组成知识发现模块.知识求精首先在领域知识可视化的基础上,集成了基于遗传知识树、知识型人工神经网络和基于解释学习的求精方法.最后将新知识转换成雄风专家系统工具XF6.2的知识表达形式,添加到其知识库中,完成专家系统的自动知识获取.
This paper introduces a comprehensive knowledge discovery and knowledge refinement system-XFKDRS, which consists of classification rules, association rules, sequential patterns, similar patterns and clustering patterns.Knowledge refinement is first based on the visualization of domain knowledge, Based on genetic knowledge tree, knowledge-based artificial neural network and interpretation-based refinement method.Finally, the new knowledge is transformed into the knowledge expression form of XF6.2, which is added to its knowledge base to complete the expert system’s automatic Knowledge acquisition.
