实现专家系统需要什么 [英] What is needed to implement an expert sytem

问题描述

我被要求实施一个关于疾病/症状的专家系统。我不知道怎么开始？我应该知道什么才能进步？



如果有人可以帮我提供演示/样本来了解这样的系统应该如何工作和/或实现我将不胜感激任何形式的帮助。我不想偷别人的努力，我只需要知道方式和想法。



我搜索了论坛，但是，没有太多的知道或是一个有用的资源。



我尝试过：



我正在尝试google。我有一些主题，但用处很少

I have been asked to implement an expert system about disease/symptoms. I do not know how to start? what things I should know to be able to progress?.

If someone can help me with a demo/sample to look how such system should work and/or implemented I will be grateful for any sort of help. I do not want to steal someones effort, all I need is to know the way and the thoughts.

I searched the forum, however, there were no too much to know or being a useful resource.

What I have tried:

I am trying to google. I got some topics but with minimal usefulness

推荐答案

首先需要专家系统 - 专家:-)

经典实现医学专家系统是基于规则的，例如发烧=>冷，更多的疾病

然后将规则放入推理系统，然后进行一次（或多次）诊断。

推理系统有一种特殊的语言叫做PROLOG和样品

祝你好运

For an expert system you need first of all - an expert :-)
Classical implementations of medical expert systems are rule based, e.g. fever => cold, more diseases
The rules are then put into an 'inference system' and out comes one (or more) diagnosis.
There is a special language for inference systems called PROLOG and there are samples
Good luck

I spent the first 8 years of my software engineering career (in the 80s) working under Dr John McDermott on XCON (then the world's largest expert system) at DEC's AI Technology Center.  Required reading for being part of his team was this seminal work that I'm happy to say is now freely available from Columbia University.
