Definition
The field of AI concerned with how to formally represent information in a way that computers can use to solve complex tasks.
Detailed Explanation
Knowledge representation involves encoding information about the world in a form that computer systems can utilize for complex problem-solving. It includes the use of ontologies, logic rules, frames, and semantic networks to structure information and relationships between concepts in a machine-readable format. This enables systems to perform complex reasoning tasks and make intelligent decisions based on stored knowledge.
Use Cases
Semantic web (improving data interoperability) expert systems (capturing expert knowledge) intelligent search engines (enhancing search results) natural language understanding.
