此文提出一种从数据库自动生成知识库的新方法。该方法根据从数据库

到知识库的优化目标函数, 利用基因遗传算法的优化手段, 直接从数据库中生成

性能较优的知识库。文中论述了该方法的原理与具体实现过程。最后, 以故障诊

断知识库的自动生成为例, 给出了应用示例, 表明了该方法的可行性与有效性。-A text knowledge base from the database automatically generated the new method. It is based on the knowledge base from the database to optimize the objective function, using genetic algorithm optimization tool, directly from the database, the knowledge base to generate a better performance. The paper describes the principle and the method of realization. Finally, the automatic generation of fault diagnosis knowledge base as an example, an application example, demonstrate the feasibility and effectiveness.
