Types of Knowledge in Artificial Intelligence

The types of knowledge include
  • Procedural knowledge
  • Declarative knowledge
  • Heuristic knowledge
Procedural Knowledge :-
  • Procedural knowledge is compiled or processed form of information.
  • Procedural knowledge is related to the performance of some task.
  • For example, sequence of steps to solve a problem is procedural knowledge.
  • In some legal systems, such procedural knowledge has been considered the intellectual property of a company, and can be transferred when that company is purchased.
  • One advantage of procedural knowledge is that it can involve more senses, such as hands-on experience, practice at solving problems, understanding of the limitations of a specific solution, etc.
Declarative Knowledge
  • Declarative knowledge is passive knowledge in the form of statements of facts about the world.
  • The type of knowledge that is, by its very nature, expressed in declarative sentences or indicative propositions.
  • For example, mark statement of a student is declarative knowledge.
Heuristic Knowledge
  • Heuristics knowledge are rules of thumb or tricks.
  • Heuristic knowledge is used to make judgments and also to simplify solution of problems.
  • It is acquired through experience. An expert uses his knowledge that he has gathered due to his experience and learning.
  • experience-based techniques for problem solving,learning and discovery that give a solution which is not guaranteed to be optimal. 
  • Where the exhaustive search is impractical, heuristic methods are used to speed up the process of finding a satisfactory solution via mental shortcuts to ease the cognitive load of making a decision.
  • Examples of this method include using a rule of thumb, an educated guess, an intuitive judgment, stereotyping, or common sense.
