Conceptual graph

Concept graph or term graphs, abbreviated Kg (English conceptual graph, CG) are developed by John F. Sowa logical language system for the semantic description of accrued knowledge domains.

In addition to the usual representation of relationships between individual units as graphs exist more textual representations, a serialization similar to N3 and a CG interchange format CGIF.

They are based on the Existential Graphs of Charles Sanders Peirce and the semantic networks of artificial intelligence.

Graphs

CGs can be represented as bipartite graphs. Boxes stand for concepts, ovals for relations. To the statement: The cat is sitting on the mattress express the following graph can be used: [ Cat ] → ( sitzt_auf ) → [ mattress ] However, this graph can also be interpreted as: A (x - arbitrary ) cat sitting on a ( x - arbitrary) mattress
