The synonymy problem (why a taxonomy is needed)
The same polymer is recorded under an abbreviation, a full chemical name and one or more trade names, as independent free-text strings. A keyword search for one misses the others. Witnesses:
| polymer | strings that co-refer (with counts) |
|---|---|
| polypropylene | PP (941) + polypropylene (940) |
| polystyrene | PS (843) + polystyrene (838) |
| polyethylene | PE (790) + polyethylene (831) + polythene (767) |
| phenol formaldehyde | PF (516) + phenol formaldehyde (517) + bakelite - generic term (490) |
| acrylic (PMMA) | PMMA (355) + polymethyl methacrylate (352) + acrylic (352) + Perspex - trade name (14) |
| polyamide | PA (428) + polyamide (431) + nylon (426) |
Trade-name strings account for 497 material assertions across 151 distinct brand tags (Perspex, Bakelite, Lycra, Neoprene, Teflon, …), each of which resolves to a generic polymer in the taxonomy.
Free-text cross-references (the latent graph)
323 descriptions contain an inline reference to another object's accession number ("AIBDC 007661.2 is the same box but a different colourway"). These are relationships trapped in prose; build_graph.py resolves them into typed object-to-object edges.
