The problems in a Question Answering system in the academic domain

Abstract

In this paper we present BRUPIA, a Question Answering (QA) system in a restricted domain: the web academic environment at the University of Alicante. This system is the transformation of an open domain QA system, AliQAn. This paper focuses on explaining how an open domain system can be transformed into another one that can successfully work on a web restricted domain. We analyze the problems of carrying out this task and we also develop the necessary resources for the new system like the corpora, the questions and the set of patterns in the new domain. Finally, a new strategic approach for the improvements in the use of the terminology in web domain is proposed. The measure of evaluation is the Mean Reciprocal Rank and the final result is 32,5%.
