Question Answering with Subgraph Embeddings

Empirical Methods in Natural Language Processing

By: Antoine Bordes, Jason Weston, Sumit Chopra

Abstract

This paper presents a system which learns to answer questions on a broad range of topics from a knowledge base using few handcrafted features. Our model learns low-dimensional embeddings of words and knowledge base constituents; these representations are used to score natural language questions against candidate answers. Training our system using pairs of questions and structured representations of their answers, and pairs of question paraphrases, yields competitive results on a recent benchmark of the literature.
