Expert system for earthquake prediction（ESEP）（2）－Knowledge representation and evidence combination

This paper deals with knowledge representation of ESEP (Expert System for Earthqauke Prediction). Attending the characteristics of the knowledge in earthquake prediction domain, production representation and procedural representation are connected in the knowledge repesentation model of ESEP named ESEP/K, and three new ways of evidence conbination are proposed for production rules besides 'AND' and 'OR'.

Knowledge Representation Methods in Expert System for Earthquake Prediction ESEP 3.0

Knowledge representation is a key to the building of expert systems. The performance of knowledge representation methods directly affects the intelligence level and the problem-solving ability of the system. There are various kinds of knowledge representation methods in ESEP3.0. In this paper, the authors introduce the knowledge representation methods, such as structure knowledge, seismological and precursory forecast knowledge, machine learning knowledge, synthetic prediction knowledge, knowledge to validate and verify certainty factors of anomalous evidence and support knowledge, etc. and propose a model for validation of certainty factors of anomalous evidence. The knowledge representation methods represent all kinds of earthquake prediction knowledge well.

地震预报专家系统(二)——知识表示和证据组合

研究了地震预报专家系统 ESEP 的知识表示.ESEP 的知识表示模型为 ESEP/K,它从地震预报领域知识的特殊性着眼,结合了产生式表示和过程表示两种知识表示方法,在产生式规则中,除常用的证据组合方式“AND”和“OR”外,我们还设计了三种新的证据组合方式.

资源型城市主导产业选择方法研究*——以新疆巴州为例

主导产业对区域经济发展有着巨大的带动作用,结合区域具体情况构建主导产业选择方法论,对区域经济政策的制定具有极其重要的参考价值。本文结合资源型城市情况,从产业运行效率、产业发展规模、产业能耗污染3个维度,综合运用数据包络分析、层次分析法等构建了ESEP资源型城市主导产业选择方法,为资源型城市主导产业选择提供了新的方法和视角,并以新疆巴州为例进行了实证研究,为巴州产业政策的制定提供了导向和依据。
