Introduction

Teaching machines are you answer questions automatically in a natural language has been a long standing goal in AI. There has been a rise in large scale structured knowledge bases (KBs), such as Freebase (cite), to tackle the problem known as open-domain question answers (or open QA). However, the scale and difficulty for machines to interpret natural language still makes this problem challenging.

open QA techniques can be classified into two main categories:

  • Information retrieval based: retrieve a broad set of answers be first query the API of the KBs then narrow down the answer using heuristics
  • Semantic parsing based:
