Extraction of How-to Type Question-Answering Sentences Using Query Sets

  • Conference paper

Part of the Lecture Notes in Computer Science book series (LNAI,volume 7457)

Abstract

In this study, we describe how to extract a sentence which serves as a correct answer for a how-to question about actions to be taken on the Web. The distinguishing feature of this study is the extraction of sentences using a set of queries, after collecting queries considered to be effective for answer extraction. By using a query set, it is possible to extract the answer considered to express the contents of the Web page pertinent to the question. In the results of the experiment, the average recall was 77.3% and the average precision was 62.9%.
