Diego Mollá, Menno M. van Zaanen, Luiz Augusto Sangoi Pizzato · 2004
AnswerFinder combines lexical, syntactic, and semantic information in various stages of the question answering process. The candidate sentences are preselected on the basis of (i) the presence of named entity types compatible with the expected answer type, and (ii) a score combination of the overlap of words, grammatical relations, and flat logical forms. The candidate answers, in turn, are extracted from (i) the set of compatible named entities and (ii) the output of a logical-form pattern matching algorithm. 1
