Knowledge Based System 

KBSKnowledge Based System is a computer system that contains a database of knowledge and programmes for processing that knowledge in order to solve problems and aid decision making. KBSs were developed from research into artificial intelligence when it was discovered that using rules of thumb allowed programmes to solve problems which were otherwise difficult to solve by standard computer techniques. As with all disciplines there are a number of key definitions relating to KBSs:
  • knowledge is information that can be used in a decision process;
  • meta-knowledge is knowledge on the knowledge, for example how important the knowledge is;
  • a domain is a particular field of knowledge, for example ultrasonic testing of steels;
  • PSM is a problem solving method.
The figure shows the basic construction of a KBS.
