Abstract

Dynamisation in Conceptual Graph Theory has been stimulated by mostly two trends: one inspired by computer science notions of actors and agents and the other one by computational semantics; we focus on the later, following John Sowa's parallel between Existential Graphs and Discourse Representation Theory or more generally Dynamic Semantics. CGs are usually interpreted by mean of a translation into FOL or directly but with a similar static impact, by mean of classical set-theoretic extensional semantics. This classical view in which meaning equals truth conditions does not capture contextual information. We propose to adopt the Dynajnic Semantics shift in which the meaning of a graph is chaxacterized by the change of information brought in an information state when it is updated with the graph.
