Challenge of maintaining coherent persona or content over longer generated texts
Neighborhood — ranked by edge-count

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.
- Ability to maintain structural consistency over extended sequences
- Ability to maintain organized behavior over extended scales; shown limited in flat autoregressive models, enabled in hierarchical/biological systems.
- The extent to which an LM's beliefs respect logical entailment: if it believes A and A→B, it should also believe B.
- Overall human-LLM judge agreement rate for coherency is 91.7% across 120 pairwise judgmentsfinding0.744Validates the LLM-as-a-Judge evaluation protocol for coherency scoring
- Transformer-based models like GPT-4, LaMDA, PaLM; assessed for GWT indicators.
- The core phenomenon studied: the ability of LLMs to evaluate and revise their own reasoning.
- Do LLMs have a unified representation of truth that spans structurally and topically diverse data?question0.739Central research question driving dataset design and experimental approach
- Core cross-modal empirical result: larger and better language models align better with vision models
