Tree structure

A hierarchical branching structure with single-parent nodes, which Alexander rejected for urban design.

Neighborhood — ranked by edge-count

paper

concept

Semilattice
associated_with
A non-hierarchical network structure where elements have multiple connections, proposed by Alexander for organizing complexity in cities.
semi-lattice diagram
extends
Alexander’s diagram where child nodes can belong to multiple parents, representing overlapping sets and complex urban structure, in contrast to tree.

cosine ≥ 0.65 · no typed edge

Entities in the same semantic neighborhood but without a typed relation to this one — candidates for new edges or unrecognized duplicates.
