Study on an Expert System As a Software System |

ABSTRACT:

An expert system is a software system - It attempts to reproduce the performance of one ormore human experts, most commonly in a specific problem domain, and is atraditional application and/or subfield of artificial intelligence. A widevariety of methods can be used to simulate the performance of the experthowever common to most or all are 1) the creation of a so-called"knowledge base" which uses some knowledge representation formalismto capture the subject matter experts (SME) knowledge and 2) a process ofgathering that knowledge from the SME and codifying it according to theformalism, which is called knowledge engineering. Expert systems may or may nothave learning components but a third common element is that once the system isdeveloped it is proven by being placed in the same real world problem solvingsituation as the human SME, typically as an aid to human workers or asupplement to some information system.
