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.
- Sets that are images of a closure operator; in FCA the extents and intents of formal concepts.
- Dynamic condition: ending a branch or closing a frame.
- A hypothesized intermediate-level linearly-represented feature (e.g., Beijing and China are closely associated) that may correlate with truth in unnegated datasets but anti-correlate in negated ones
- Operators X → X'' on subsets of objects or attributes, satisfying extensivity, monotonicity and idempotence.
- Efficient algorithm for computing all closed sets (intents or extents) in lectic order without storing exponential lists.
- A set property meaning all coordinate patches of its elements remain within the set; proved equivalent to axis-aligned hyperrectangles
- Method used with Andre and Anna: standing on site with eyes closed, abandoning preconceptions, visualizing the most comfortable remembered place
