Active Learning for Building a Corpus of Questions for Parsing

Jordi Atserias, Giuseppe Attardi, Maria Simi, Hugo Zaragoza


Abstract
This paper describes how we built a dependency Treebank for questions. The questions for the Treebank were drawn from questions from the TREC 10 QA task and from Yahoo! Answers. Among the uses for the corpus is to train a dependency parser achieving good accuracy on parsing questions without hurting its overall accuracy. We also explore active learning techniques to determine the suitable size for a corpus of questions in order to achieve adequate accuracy while minimizing the annotation efforts.
