CFO: Conditional Focused Neural Question Answering with Large-scale Knowledge Bases

Understand

How can we enable computers to automatically answer questions like "Who created the character Harry Potter"? Carefully built knowledge bases provide rich sources of facts.

• However, it remains a challenge to answer factoid questions raised in natural language due to numerous expressions of one question.
• In particular, we focus on the most common questions --- ones that can be answered with a single fact in the knowledge base.
• We propose CFO, a Conditional Focused neural-network-based approach to answering factoid questions with knowledge bases.
