Current progress and boundaries
Research search, semantic search, and literature question-answering tools are advancing quickly, but coverage, version management, and citation accuracy vary.
Why it remains difficult
Preprints, retractions, duplicate studies, and varying terminology complicate retrieval. Models may present correlation as causation or overlook counterexamples.
Paths worth exploring
Attach the original source, publication status, and search date to every claim. Support inclusion criteria, reasons for exclusion, and a record of researchers? manual revisions.
How to evaluate success
Have researchers in the field sample-check recall, citation support, coverage of important counterexamples, and review freshness, ensuring conclusions trace back to original evidence.
