Answering the Hard Questions

摘要

We present an end-to-end system for open-domain non-factoid question-answering. To accomplish this we leverage the information on the ever-growing World Wide Web, and the capabilities of commercial search engines to find the relevant information. Our QA system is composed of three components: (i) query formulation module (QFM) (ii) candidate answer generation module (CAGM) and (iii) answer selection module (ASM). A thorough empirical evaluation using two datasets demonstrates that the proposed approach is highly competitive.
