Research Collaboration ML Matching API

A Python and FastAPI matching service case study used by Fusio(n) for researcher-to-researcher matching, combining transformer embeddings, structured profile categories, bidirectional scoring, caching, and accelerated inference.

PythonFastAPIPyTorchTransformersSPECTER2
  • Implemented a companion ML matching service that Fusio(n) can call for collaborator ranking and workgroup formation instead of keeping all matching logic inside Laravel.
  • Implemented multiple matching paths: legacy SciBERT matching, SPECTER2 technical matching, fast structured category matching, and all-MiniLM-L6-v2 broad matching.
