What is meant by knowledge representation?

Knowledge-representation is a field of artificial intelligence that focuses on designing computer representations that capture information about the world that can be used to solve complex problems. There is no more powerful formalism than that used by mathematicians to define general propositions about the world.

.

Similarly, you may ask, how is knowledge represented?

In logic, knowledge is represented by propositions and is processed through reasoning by the application of various laws of logic, including an appropriate rule of inference. Fuzzy logic uses the fuzzy set theory and approximate reasoning to deal with imprecision and ambiguity in decision making.

Furthermore, why is knowledge representation important? It is responsible for representing information about the real world so that a computer can understand and can utilize this knowledge to solve the complex real world problems such as diagnosis a medical condition or communicating with humans in natural language.

Besides, what are the types of knowledge representation?

There are 5 main types of knowledge representation in Artificial Intelligence. Procedural Knowledge – Gives information/ knowledge about how to achieve something. Declarative Knowledge – Its about statements that describe a particular object and its attributes , including some behavior in relation with it.

What do you mean by knowledge acquisition?

Knowledge acquisition is the process of extracting, structuring and organizing knowledge from one source, usually human experts, so it can be used in software such as an ES. This is often the major obstacle in building an ES.

There are numerous theories of how knowledge is represented and organized in the mind, including rule-based production models, distributed networks, and propositional models. A semantic network is a method of representing knowledge as a system of connections between concepts in memory.
