Abstract

This paper describes briefly the application of Conceptual Graphs (CG) in a tutoring environment for teaching English terminology and emphasises on knowledge acquisition results in the domain of finances. There are two important requirements imposed on the conceptual representation --- firstly, it should be clear and intuitive enough to be shown to the learner with pedagogic purposes and should allow for simple graphical visualisation and secondly, it should be sofisticated enough to serve as an input to a Natural Language Understanding (NLU) component, allowing analysis of the learners' answers. The possibilities to use one and the same knowledge base for both purposes are investigated and the paper shows that in a practically situated task-dependent paradigm, most ontological choices - granularity of concept types, conceptual relations, explicit and implicit concept hierarchy, are influenced by the task requirements
