KQA Pro: A Dataset with Explicit Compositional Programs for Complex Question Answering over Knowledge Base. (arXiv:2007.03875v4 [cs.CL] UPDATED)

Complex question answering over knowledge base (Complex KBQA) is challenging
because it requires various compositional reasoning capabilities, such as
multi-hop inference, attribute comparison, set operation. Existing benchmarks
have some shortcomings that limit the development of Complex KBQA: 1) they only
provide QA pairs without explicit reasoning processes; 2) questions are poor in
diversity or scale. To this end, we introduce KQA Pro, a dataset for Complex
KBQA including ~120K diverse natural language questions. We introduce a
compositional and interpretable programming …
