KBQA: Learning Question Answering over QA Corpora and Knowledge Bases
Summary: KBQA: a template-based NL-to-query system over QA corpora and knowledge bases. Learned 27M templates for 2782 intents; 57× expansion of RDF predicates boosts KB coverage; supports binary factoid and multi-hop questions, achieving SOTA on QALD. (summarized by gpt-5-nano on Feb 09 2026)
