Explains the published frameworks of data quality dimensions
Strong and Wang (intrinsic, contextual, representational and accessibility dimensions), Redman, English, and the DAMA UK core dimensions (completeness, uniqueness, timeliness, validity, accuracy, consistency); dimensions are measured objectively or by the judgement of data consumers.
Can AI do this?
People still lead Few or none of the tested AI models showed they master this. 0 of 4 models in the current benchmark master it.
| Model | Tier | Probability of mastery | Status |
|---|---|---|---|
| gemini-4-argon | Flagship | 44% | Not shown |
| gemini-3.5-flash-lite | Low cost | 44% | Not shown |
| gpt-6-luna | Low cost | 44% | Not shown |
| claude-haiku-5-5 | Low cost | 44% | Not shown |
Mastered means a probability of at least 90% that the model has this knobit, estimated from its graded answers. “Not shown” means the answers do not settle it either way. How the models are tested.
What it looks like in practice
Expected result: Strong and Wang (intrinsic, contextual, representational and accessibility dimensions), Redman, English, and the DAMA UK core dimensions (completeness, uniqueness, timeliness, validity, accuracy, consistency); dimensions are measured objectively or by the judgement of data consumers.
