【摘要】 知识表示是专家系统建造中的一个关键环节 ,知识表示方法的好坏直接关系到系统的智能水平和解决问题的能力。在地震预报专家系统ESEP 3 0中有多种知识表示方法 ,本文介绍了该系统的结构知识、地震学和前兆预报知识、机器学习知识、综合预报知识、确定异常证据可信度知识以及支持知识等多种知识表示方法 ,提出了确定异常证据可信度模型。这些知识表示方法可以很好地表示各类地震预报知识更多还原

【Abstract】 Knowledge representation method is a key in building the expert system. The quality of knowledge representation method relate to the intelligent level and the capacity solved problems used the expert system. There are many knowledge representation methods in the expert system for earthquake prediction (ESEP 3.0). The representation method of structure knowledge, prediction knowledge of seismology and precursory, machine study knowledge, comprehensive knowledge, the knowledge to confirm certainty factor of anomaly and support knowledge are introduced. The model to confirm certainty factor of anomaly is proposed too. Those knowledge representation methods can be well represent varied knowledge of earthquake forecasting.更多还原
