OpenCogPrime:ContextAtom
From OpenCog
Context Atoms
Next, a Context is simply an Atom that is used as the source of a PLN ContextLink, for instance
Context
quantum_computing
Inheritance Ben amateur
or
Context
game_of_fetch
PredictiveAttraction
Evaluation give (ball, teacher)
Satisfaction
The former simply says that Ben is an amateur in the context of quantum computing. The latter is a more pertinent example to the present page: it says that in the context of the game of fetch, giving the ball to the teacher implies satisfaction.
Note: in the implementation of OpenCog, ContextLinks are implicit rather than explicit entities. An atom can contain a CompositeTruthValue which in turn contains a number of VersionHandles. Each VersionHandle associates a Context or a Hypothetical with a TruthValue.
