arXiv paper proposes federated approach to knowledge graph question answering
A new arXiv preprint examines knowledge graph question answering in settings where no single organization holds the entire graph. The authors describe a scenario in which parties share entity identifiers but own disjoint sets of relations, so federated methods are needed to reason across them. The paper presents design lessons from a working system and an interactive prototype.
