Knowledge-representation is a formal system for encoding information, facts, and relationships in a structure that can be stored, retrieved, and reasoned about by humans or machines. Its parameters are: (1) a structured format (schemas, ontologies, graphs, logic, or other formalisms), (2) a defined semantics specifying what the structures mean, (3) operations for inference, querying, or transformation. It persists through standardization, implementation in systems, and the conventions of the communities that use it.

Definition
Why it is in scope
Knowledge-representation is a human-made cognitive construct: the concept of encoding, structuring, and storing knowledge in accessible, manipulable forms. It is not the natural act of remembering (that is territory), but the map — the categories, formats, and media (language, writing, diagrams, databases, schemas) that humans built to externalize and share memory. It persists through teaching, writing systems, and formal notation, and it is entirely output by human making.

Knowledge representation formalizes knowledge using logical structures (ontologies, frames, semantic networks). Remove logical formalism and knowledge representation as a discipline ceases to operate.
Relations to this entry
- cmrmp851r0160d1nl3rlfwv3r← INSTANCE_OF
A cognitive map IS a specific kind of knowledge-representation. It is a structured internal representation that organizes information about spatial and conceptual relationships — a particular type of how knowledge is represented. Direction tested: cognitive-map is the specific, knowledge-representation is the general. Law 9.
- cmrus0lww02fxr671ehy9e85l← INSTANCE_OF
semantic-web is a specific approach to structuring web data for machine interpretation — it IS a form of knowledge representation. Direction: semantic-web (epoch ~2001) is newer than knowledge-representation (much older). A competent speaker would call the semantic web 'a form of knowledge representation.'
- cmrmudc7001mtd1nlw6ltsqg7← INSTANCE_OF
concept-mapping IS a specific kind of knowledge-representation — a diagrammatic method (nodes + labeled edges) for representing semantic relationships among concepts. knowledge-representation is the nearest general kind. Law 9: specific→general.
- cmrmemk6p00gidveaasfj9qih← INSTANCE_OF
An ontology is a specific kind of knowledge representation — a formal, explicit specification of concepts within a domain. Per Law 9, a competent speaker would call an ontology 'a type of knowledge representation.'
- cmrmefzfr00eudveaiyr1pcc2← INSTANCE_OF
A schema is a specific kind of knowledge-representation: a structured cognitive framework for organizing and interpreting information. A competent speaker would call a schema 'a form of knowledge representation.' Nearest kind.
- cms8dgq6i00j773fksyy8pltn← DEPENDS_ON
An inference engine applies reasoning rules to a knowledge base — remove structured knowledge representation and it has nothing to reason over. The removal test fails: no knowledge base = no inference. Direction: inference-engine needs knowledge-representation to operate.
- cmrq6p9im08rvd1nl15l5ttd6← SERVES
A concept map is built and maintained for the sake of knowledge representation — it externalizes and structures relationships between concepts visually. Law 8d.
- cmrus0lww02fxr671ehy9e85l← SERVES
Semantic web is built and maintained for the sake of enabling machine-readable knowledge representation and linked data interoperability. The servant points at the master purpose: structured representation for agents and humans. This is a teleological SERVES relation, not operational DEPENDS_ON: removing knowledge representation as a goal does not stop the web operating, but the design intent is for whose sake.
