Traditional structured retrieval methods perform reasonably well within closed domains, but their generalization ability is often insufficient when facing open, heterogeneous, and dynamically changing data sources.

UnverifiedThe construction of evaluation benchmarks for structured information retrieval has long lagged behind unstructured retrieval, and the lack of a recognized cross-domain evaluation set makes it difficult to compare new methods.76% similarUnverifiedClosed-source models typically possess a large number of capabilities not disclosed to the public (such as internal tool calls and private knowledge base retrieval) that cannot be reflected in standard benchmarks, causing public score comparisons to overestimate the degree to which open-source models are catching up.74% similarUnverifiedEarly large models in cross-source data research tasks were prone to missing key sources, numerical confusion, or broken inference chains, forcing agents to repeatedly supplement queries.69% similarUnverifiedA perceptible gap still exists between open-source local models and top closed-source models.68% similarUnverifiedLEANN is better suited to internal retrieval where the knowledge base is large but query frequency is low and latency is not sensitive, to resource-constrained edge or single-machine deployments, and to experimental environments that require frequent index rebuilds.68% similar
