Bidirectional Expansion For Keyword Search on Graph Databases
Summary: Introduces bidirectional keyword search over graph databases, combining backward expansion from keyword matches with forward exploration from candidate roots. A spreading-activation frontier prioritization mitigates high-match and high-degree bottlenecks, substantially outperforming backward-only search. (summarized by gpt-5.6-luna on Jul 24 2026)
