What is logic based representation?

What is logic based representation?

Logical Representation Logical representation means drawing a conclusion based on various conditions. This representation lays down some important communication rules. It consists of precisely defined syntax and semantics which supports the sound inference.

What are the various knowledge representation schemes?

There are four types of Knowledge representation : Relational, Inheritable, Inferential, and Declarative/Procedural.

What is logic based knowledge?

Logical knowledge is, roughly speaking, knowledge about logic—such as knowledge that a certain principle of inference necessarily preserves truth, or that every proposition of a certain form must be true—and so is not the same thing as knowledge that is gained by using logic, i.e. inferential knowledge.

What are the 3 ways to represent knowledge?

Knowledge (K) can be formally represented by three tuples, K = (C, I, A).

  • C is a set of classes represented by class objects.
  • I is a set of instances represented by instance objects.
  • A is a set of attributes possessed by the classes and instances.

What is first order logic in AI?

First-order logic is another way of knowledge representation in artificial intelligence. It is an extension to propositional logic. FOL is sufficiently expressive to represent the natural language statements in a concise way. First-order logic is also known as Predicate logic or First-order predicate logic.

What is the knowledge representation in AI?

Knowledge representation and reasoning (KRR, KR&R, KR²) is the field of artificial intelligence (AI) dedicated to representing information about the world in a form that a computer system can use to solve complex tasks such as diagnosing a medical condition or having a dialog in a natural language.

How is knowledge related to logic?

“Logical knowledge” can be understood in two ways: as knowledge of the laws of logic and as knowledge derived by means of deductive reasoning. To begin with, we must specify what is a law of logic—not an entirely straightforward task. There are three, not all mutually exclusive, conceptions of logic laws.

What is knowledge representation write the names of different types of knowledge representation?

Procedural Knowledge – This is responsible for knowing how to do something and includes rules, strategies, procedures, etc. Meta Knowledge – Meta Knowledge defines knowledge about other types of Knowledge. Heuristic Knowledge – This represents some expert knowledge in the field or subject.

What are the two main entities dealt in knowledge representation?

In the complete cycle, the main components are knowledge representation and Reasoning. These two components are involved in showing the intelligence in machine-like humans.

Which is an alternative of predicate logic for knowledge representation?

Semantic networks are alternative of predicate logic for knowledge representation. In Semantic networks, we can represent our knowledge in the form of graphical networks. This network consists of nodes representing objects and arcs which describe the relationship between those objects.

Why do we need a good knowledge representation scheme?

A good knowledge representation scheme should be able to provide an explanation of its inference and allow justifications of its reasoning. The chain of reasoning should be explicit. 7. Efficiency: The scheme should not only support inference of new knowledge from old but must do so efficiently in order for new knowledge to be used.

What are the four types of knowledge representation?

Knowledge Representation Schemes There are four types of Knowledge representation : Relational, Inheritable, Inferential, and Declarative/Procedural.

How are syntaxes and semantics used in knowledge representation?

Syntaxes are the rules which decide how we can construct legal sentences in the logic. It determines which symbol we can use in knowledge representation. How to write those symbols. Semantics are the rules by which we can interpret the sentence in the logic. Semantic also involves assigning a meaning to each sentence.
