Automatic feature engineering for Italian question answering systems
Antonio Emmanuele Uva, Alessandro Moschitti · 2015
Abstract. In this paper, we propose automatic feature engineering for Italian QA systems. Our approach only requires a shallow syntactic rep-resentation of the questions and the answer passages. We apply Support Vector Machines using tree kernels to such trees for automatically gener-ating relational syntactic patters, which significantly improve on BM25 retrieval models.
