A Universal Question-Answering Platform for Knowledge Graphs
Summary: Universal QA for knowledge graphs via a neural sequence-to-sequence that converts questions into a KG-agnostic abstract representation. A just-in-time linker maps that representation to SPARQL over any KG using public APIs and RDF indices, with no pre-processing, achieving strong results on unseen KGs.
