基于层次知识模型的知识库可视化研究

针对专家系统知识库可视化问题,构建了知识库的层次知识模型,基于径向树实现了层次知识模型的可视化.以基于多级知识单元的知识库为例,研发了知识库可视化系统,通过系统运行的实例验证了该方法能够方便用户快速浏览知识库的层次结构,从而有利于提高知识库的可理解性.该方法对其它知识表示方法的知识库可视化具有借鉴意义.

Research on Visualization of Knowledge Base Based on Level Knowledge Mode

According to the visualization of knowledge base of expert system,the level knowledge model of knowledge base has been constructed and the visualization of hierarchical knowledge model based on radial tree has been realized.Based on the knowledge base of the multilevel knowledge unit,the knowledge base visualization system is developed and the example of system operation shows that this method can help users to quickly browse the hierarchy of knowledge base,which is beneficial to improve the understanding of the knowledge base.This method also has reference value to the knowledge base which is expressed by other knowledge.
