The PARADOCS Project
PARADOCS is a Prolog implementation of a reasoning system for a subset of TAL, that views Planning And Reasoning As DeductiOn with ConstraintS. It supports prediction from a fully instantiated set of actions, planning from the empty set of actions, and anything in between.
PARADOCS can be used to reason about a subset of TAL narratives that can be encoded using Horn clauses that are in close correspondence with the first-order TAL axioms. Temporal relations are managed by a general temporal constraint network implemented by a set of constraint handling rules (CHR), resulting in a plan structure that is more expressive than that of partial-order plans.
PARADOCS has been succeeded by the Logical Agents architecture.
