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 topicoriented 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.
