- derivation operatorsassociated_withMappings A' = {m | ∀g∈A: gIm} and B' = {g | ∀m∈B: gIm} that form the basis of concept formation.
- Concept Latticeassociated_withCentral algebraic structure in FCA that orders formal concepts and preserves information from formal contexts.
- implicationassociated_withImplication A → B holds in a formal context iff every object that has all attributes in A also has all in B.

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.
- A pair (A, B) where A is an extent of objects and B is an intent of attributes, satisfying closure conditions.
- Finite number of previous tokens used by autoregressive models to predict the next token; defines interaction range
- Ganter's assertion that concept lattice transformation does not lose information from the original formal context.
- Feature that activates across all tokens within a specific context (e.g., DNA sequences, base64 strings)
- A morphological quality typical of living structure, combining informality with an underlying formal order.
