Contextuality and non-extensional identity: the inescapable symbiosis in NLP
In this paper we examine two kernel traits that a KR approach has to share in order to capture traditional structuralist analysis of semantics: non-extensionality and semantic identification/differentiation. We set up the formal requisites for a non-extensional definition of representational entities. The notion of identity is re-evaluated supporting modularity. Its partial forms, seen as particular effects of interpretational strategies, are investigated.
