Abstract

Described herein are systems and methods for determining how to automatically answer questions like 'Where did Harry Potter go to school?' Carefully built knowledge graphs provide rich sources of facts. However, it still remains a challenge to answer factual questions in natural language due to the tremendous variety of ways a question can be raised. Presented herein are embodiments of systems and methods for human inspired simple question answering (HISQA), a deep-neural-network-based methodology for automatic question answering using a knowledge graph. Inspired by human's natural actions in this task, embodiments first find the correct entity via entity linking, and then seek a proper relation to answer the question—both achieved by deep gated recurrent networks and neural embedding mechanism.
