Implementation of poisoning diagnosis expert system based on decision tree
基于决策树的中毒诊断专家系统实现

In order to judge the poisoning quickly through poisoning diagnosis expert system,after analyzing the failure of previous model of inference,a novel model of inference was put forward with which the expert system applies,and the particular method of implementation was introduced.This system firstly set up a decision tree according to the symptoms doctor known and thinking enough of its diagnostic contribution and diagnostic expense,and then found the result(the cause of poisoning) through repeatedly heuristic deduction.System test shows that it achieves the desired result.
