cosine ≥ 0.65 · no typed edgeEntities in the same semantic neighborhood but without a typed relation to this one — candidates for new edges or unrecognized duplicates.
- Alexander’s diagram where child nodes can belong to multiple parents, representing overlapping sets and complex urban structure, in contrast to tree.
- Fundamental structure: a set with a reflexive, antisymmetric, transitive relation.
- Alexander's position in 'A City Is Not a Tree' that hierarchical tree structures sever urban life while semilattices enable overlapping, living systems.
- A construction paradigm in which each operation naturally generates the next, producing unique adaptation without complex drawings.
- APL pattern requiring a focus approximately in the middle of a square, demonstrating roughness by allowing the position to meet other important criteria rather than being perfectly centered
- Hippocampal neural coding phenomenon reproduced by active inference.
