Researchers have developed SeedER, a new retrieval framework designed to efficiently navigate and extract information from knowledge graphs. SeedER addresses the challenges of rapid ego-graph expansion and the limitations of dense embedding methods for complex queries. The framework uses a two-stage process: first, it identifies core nodes with lightweight retrieval, and then it employs a learned policy to selectively expand these nodes, controlling costs while improving recall for knowledge-intensive reasoning systems.
