Abstract

In this paper, we present and analyze the results of the application of a text summarization system – GistSumm – to the task of monolingual question answering at CLEF 2006 for Portuguese texts. We hypothesized that topic-oriented summarization techniques could be able to produce more accurate answers. However, our results showed that there is a big gap to be overcome for summarization to be directly applied to question-answering tasks.
