EXPERT SYSTEM

An expert system is software that attempts to provide an answer to a problem, or clarify uncertainties where normally one or more human experts would need to be consulted. Expert systems are most common in a specific problem domain, and is a traditional application and/or subfield of artificial intelligence. A wide variety of methods can be used to simulate the performance of the expert however common to most or all are 1) the creation of a so-called "knowledgebase" which uses some knowledge representation formalism to capture the Subject Matter Expert's (SME) knowledge and 2) a process of gathering that knowledge from the SME and codifying it according to the formalism, which is called knowledge engineering. Expert systems may or may not have learning components but a third common element is that once the system is developed it is proven by being placed in the same real world problem solving situation as the human SME, typically as an aid to human workers or a supplement to some information system.

As a premiere application of computing and artificial intelligence, the topic of expert systems has many points of contact with general systems theory, operations research, business process reengineering and various topics in applied mathematics and management science.


4 Rule-based Expert Systems
A rule-based expert system is an expert system (see intro) which works as a production system in which rules encode expert knowledge.
Most expert systems are rule-based. Alternatives are
frame-based - knowledge is associated with the objects of interest and reasoning consists of confirming expectations for slot values. Such systems often include rules too.
model-based, where the entire system models the real world, and this deep knowledge is used to e.g. diagnose equipment malfunctions, by comparing model predicted outcomes with actual observed outcomes
case-based - previous examples (cases) of the task and its solution are stored. To solve a new problem the closest matching case is retrieved, and its solution or an adaptation of it is proposed as the solution to the new problem.

3. Buka program prolog kemudian pilih File-Consult. Buka file yang tadi dengan format .pl
4. Kemudian untuk mencari all mammal kita ketik animal(mammal,MAMMAL,_,_). Lalu tekan
enter. Kemudian akan muncul binatang mammal pertama, lalu tekan ; sampai muncul no.
5. Kemudian memunculkan hewan mammal yang juga carnivore ketik
animal(mammal,X,carnivore,_). Sehingga muncul binatang pertama, lalu tekan ; sampai
no.
6. Untuk memunculkan hewan mammal yang mempunyai strip belang kita ketik
animal(mammal,Y,_,stripes). Lalu akan muncul binatang pertama, lalu tekan ; sampai no.
7. Yang terakhir kita memunculkan hewan reptil yang juga termasuk mane, maka kita ketik
animal(reptile,Z,_,mane). lalu tekan enter. Karena tidak ada maka akan muncul no.

"TUTORIAL"

1. ketik di notepad:
