SeedER: Seed-and-Expand Retrieval from Knowledge Graphs
A retrieval framework for knowledge graphs that leverages structure through iterative expansion.
The authors introduce SeedER, a retrieval framework for knowledge graphs that explicitly uses graph structure to improve efficiency and effectiveness.,SeedER first seeds a compact set of core nodes using lightweight dense and entity-based retrieval, then selectively expands this set via a learned policy.,This design enables efficient discovery of query-relevant nodes while controlling expansion cost.
