How it works
Semantic search. Not keyword matching.
SourceTracer understands the meaning of your query and matches it against the scientific meaning of every article — not just the words.
SourceTracer gives developers and research teams instant semantic access to the entire PubMed corpus — no infrastructure, no indexing, no waiting.
