: We describe the use of an LCS-based semantics for question-answering exercises in foreign language training. We start by reviewing the LCS model and show how this representation can be used to support a question answering lesson as well as a limited domain discourse. An authoring tool for entering the relevant semantic knowledge is also described. 1 Introduction The chapters in this book result from a workshop which presented a number of stateof -the-art projects in Intelligent Computer Aided Language Learning (ICALL). At that workshop, several different speakers stated that the study of syntactic processing was at a mature enough state that it could be reliably used as a basis for tutoring systems. Semantic knowledge, however, was deemed to be less well understood and not reliable for use outside of extremely limited domains such as graphics microworlds or "adventure game" level discourse. Further, authoring of semantic knowledge was dismissed as not currently available. It is our ...
