Abstract

This paper discusses the participation of the University of Alicante in the Answer Validation Exercise (AVE) track. First, the proposed system uses a set of regular expressions in order to join the question and the answer into a declarative sentence, and afterwards applies several lexical-semantic inferences to attempt to detect whether the meaning of this sentence can be inferred by the meaning of the supporting text. Throughout the paper, we describe a basic system configuration and how it is enriched by the addition of semantic constraints. Moreover, we want to apply special emphasis to the language-independent capabilities of some system components. As a result, we were able to apply our techniques over both Spanish and English corpora achieving the first and second position in the AVE ranking.
