How this triple was built (1 step)

Every LLM step that produced this triple, in pipeline order — named-entity classification, the disambiguation choices (the exact options shown, with the pick highlighted), and the generated description. The batch + timestamp of each is in the Provenance table below.

CD Concept disambiguation gpt-5-mini-2025-08-07
Target class: polymerization catalyst
Context triple: [Ziegler–Natta catalysts, instanceOf, polymerization catalyst]
  • A. acid-catalyzed reaction
    An acid-catalyzed reaction is a chemical process in which an acid donates protons or stabilizes intermediates to increase the rate of reaction without being consumed.
  • B. alkylidene complex
    An alkylidene complex is a coordination compound in which a metal center is double-bonded to a carbon atom that is also bonded to an alkyl group, forming a metal–carbon double bond (M=CR₂).
  • C. carbene complex
    A carbene complex is a coordination compound in which a metal center is bonded to a divalent carbon atom (a carbene), often stabilizing otherwise highly reactive carbene species and enabling diverse organometallic reactions.
  • D. polymer brand
    A polymer brand is a named line of polymer-based materials or products, distinguished by specific performance characteristics, formulations, and market positioning under a particular manufacturer or trademark.
  • E. high-performance polymer material
    A high-performance polymer material is an advanced synthetic polymer engineered to exhibit exceptional mechanical, thermal, chemical, and/or environmental resistance properties for demanding applications beyond those of conventional plastics.
  • F. None of above. chosen

Provenance (1 batch)

The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
