Explains hierarchical relations and the all-and-some test

K-451 · Knowledge knobit · Activity: Build the conceptual model and taxonomies · Competence: Data modelling

Generic, instance and whole-part relations, and the test that a child is always a kind of its parent (ANSI/NISO Z39.19).

Can AI do this?

AI does this well Most of the tested AI models master this. 10 of 10 models master it.

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: Generic, instance and whole-part relations, and the test that a child is always a kind of its parent (ANSI/NISO Z39.19)

How it is assessed: Classifies sample links and applies the all-and-some test to them
