The tree structure can be reconstructed from its versus relation.

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

• Tree structureconcept0.801
  A hierarchical branching structure with single-parent nodes, which Alexander rejected for urban design.
• Characterize treelike versus-relations! Can this perhaps be done automatically?question0.793
  Central open question in evolutionary tree analysis: find axioms describing versus-relations derived from trees.
• The creation of living structure cannot be done in any other way.claim0.788
• graph vs tree mental structuresconcept0.785
  Proposed difference between ADHD (graph-structured) and neurotypical (tree-structured) mental organization for tanha management.
• The structures where life occurs just cannot be made in any other way.quote0.778
  Categorical assertion about the necessity of the living process.
• The degree of similarities which exist in a structure must correspond exactly to the degree of similarity of the conditions there, and the degrees of differences which exist in a structure must also correspond to the degrees of difference in the conditions there.claim0.778
  The profound principle that underlies all living structure; symmetry as the mathematical trace of necessity.
• A structure is truly generated, and perceived as having life, only when it has unfolded from a nice, beautiful sequence of differentiations.claim0.777
  The most profound claim of the chapter: the niceness of the sequence is directly perceptible in the built form and is the ultimate source of living quality.
• Complex, generated structure cannot be arrived at in any other way.quote0.777
  Concise statement that underscores the necessity of the generated process for real complexity.
