Erkan Tin, Varol Akman : Bilkent University : {tin,akman}@bilkent.edu.tr Computational Situation Theory preprints/Logic Situation theory has been developed over the last decade and various versions of the theory have been applied to a number of linguistic issues. However, not much work has been done in regard to its computational aspects. In this paper, a medium (called BABY-SIT) which uses situation-theoretic constructs as its computational foundation is proposed. The features of this experimental environment are compared to those of the existing approaches towards `computational situation theory.' N.B.
