Abstract

We describe the background and motivation for a logic-based framework, based on the theory of “Knowing-Aboutness”, and its specific application to Question-Answering. We present the salient features of our system, and outline the benefits of our framework in terms of a more integrated architecture that is more easily evaluated. Favourable results are presented in the TREC 2004 Question-Answering evaluation.
