Papers on the Logic of Context and Contextual Reasoning


 My work on the logic of context tries to bring together the older ideas of Richard Montague
 and David Kaplan with more recent attempts to formalize context in logical AI,
 especially John McCarthy's ideas.

 The basic idea I am trying to develop is that a type-theoretic formalism,
 based on Montague's Intensional Logic but with suitable extensions of the logical
 apparatus, provides a natural and adequate foundation for the logic of context.
