"Search Space" of commonsense knowledge.

The reservoir of the commonsense related to most said knowledge (BTW : all knowledge in the world is said BY someone, and TO someone) is the 'speaker' and the 'listener'. Or in broader words - the 'source' of the knowledge and the 'destination' of the knowledge.

 

Consider this written outside a temple - Please remove your shoes before entering the temple.

Now, like every piece of knowledge, this too is "incomplete" and has connected bits to it, whose answer lies in commonsense. For example, who is 'your'? Remove shoes from where? 'the temple' means which temple? etc. The answers to most of these questions will lie in the "space" of the source and the destination of the data/knowledge. First question's answer - the reader's shoes. Hence, destination. Second - From the listener's (/ destination's) legs. Third - the temple to which this sign board is attached to OR the temple from which this instruction is coming from. So this is the source. 

 

This would easen the process of getting to the answer of the commonsense questions to a given piece of knowledge by narrowing the "search space (which is the 'source' and 'destination')".

 

Take another small example - Suppose a textbook says - let us delve into a further chapter. Who is 'us'? Answer to this question is the source plus the destination. (Source coming from the book - the author. And the destination being the reader). Chapter "further" to what? Answer - current chapter. This is in the "source space".
