SPARQA: Skeleton-based Semantic Parsing for Complex Questions over Knowledge Bases

Understand

Semantic parsing transforms a natural language question into a formal query over a knowledge base.

• Many existing methods rely on syntactic parsing like dependencies.
• However, the accuracy of producing such expressive formalisms is not satisfying on long complex questions.
• In this paper, we propose a novel skeleton grammar to represent the high-level structure of a complex question.
