We extract techniques developed in the Concurrent C minor project to build a framework for constructing logics that contain approximation and/or separation. Approximation occurs wh...
The development of Dialog-Based ComputerAssisted Language Learning (DB-CALL) systems requires research on the simulation of language learners. This paper presents a new method for...
