| ## 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. |
