Primes

• Schema
  • Schank & Abelson 1977 restaurant script formalized the schema concept for AI.

    This sourceLawrence Erlbaum. Foundational AI/cognitive-science account of how narrative-like knowledge structures (scripts, plans, goals) compress disconnected events into coherent causal schemas that drive comprehension and inference.

• Script
  • Where a schema is a generic structured knowledge representation — a slot-and-filler bundle that may or may not be temporally ordered — a script is specifically the temporally and causally ordered schema: this happens, then this, then this, with each step setting up the preconditions for the next, and with each role available to be filled by different actors on different occasions.

    This sourceIntroduces the script as a temporally and causally ordered knowledge structure with roles, props, and default fillers; the restaurant script is its canonical example.

Domain-specific

• Knowledge representation and reasoning
  • Representation expressiveness, inference soundness, completeness and computational tractability trade off, and stored symbols become knowledge only relative to semantics, provenance and intended use.

Verification

Does it exist? Not checked yet. This work's DOI is recorded above but has not been resolved against an external catalogue, so nothing here confirms the work exists.

Does it back the claim? Not recorded. Neither this nor any other of the 3 citations of this work carries a recorded support check.

Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
