=== What is commonsense? ===

The ambition behind commonsense computing covers all of the meanings that the vernacular connotation of "commonsense" implies.  Useful definitions will invariably exclude key components.   With this in mind, here are some approximate definitions, each from different ''perspectives'':
* ''Communication:'' Between two people, commonsense is the knowledge one person believes both people share.
* ''Goals:'' Commonsense is the world-knowledge used to build plans to solve problems, spanning semantic, procedural and episodic knowledge.
* ''Debugging'':  Commonsense reasoning requires identifying problems in problem-solving and knowledge, and reacting in the right way to maximize the learning from a single failure.
* ''Perception'': Commonsense is the learned reactions used to categorize and construct mental representations from multi-modal sensory streams.
* ''Mental Realms'': Commonsense is organized into context specific sparsely connected mental realms.  We must not only learn the connections between ways of thinking but also the disconnections between ways of thinking.
