The generic memory module stores all of the knowledge used by the DEVISER planner/reasoner. The knowledge is represented symbolically in a frame representation.
The stored knowledge is heterogeneous in that different types are stored. Complete domain knowledge is kept as a precoded structure of all possible actions and inferences in a STRIPS-like format (i.e. pre-condition/post-condition pairs). Another type of generic memory is the episodic memory, which logs of all sensor data, actions, and text input.
All of this knowledge is accessible to DEVISER, but it is completely separate from the lexipedia.
