Knowledge Base

In expert systems, the knowledge base is a critical component that stores and organizes information, rules, and facts required for intelligent decision-making.

Methods and Techniques

• Rule-Based Knowledge Representation - Represents knowledge in the form of "if-then" rules, where conditions trigger specific actions or conclusions.

• Frame-Based Knowledge Representation - Structures knowledge using frames, which are data structures that organize information about objects, entities, or concepts within a domain.

• Semantic Networks - Depicts knowledge using interconnected nodes and links to represent relationships and hierarchies between different concepts in the domain.

• Ontologies - Formalizes the relationships and concepts in a domain using a structured framework, often employing standard ontology languages such as OWL or RDF.

• Knowledge Acquisition - The process of gathering, organizing, and entering information into the knowledge base, often involving collaboration with domain experts.

• Knowledge Refinement and Maintenance - Ongoing processes to update, correct, or expand the knowledge base based on new information, changing conditions, or improvements in expertise.
