Re: "In Defense of Ambiguity"

Hi Alan:
Basically all I wanted to say is that in human communication, we clarify 
and refine the meaning associated to words in the course of 
communication, while the current SW infrastructure requires us to define 
the meaning of a conceptual element identified by a URI beforehand. 
Quite clearly, there can be multiple similar elements with different 
URIs. But we cannot currently negotiate the meaning of this very URI.

My main concern is that reducing query answering to querying a static 
representation may be too simple an approach, same as matchmaking for 
needed products is not a simple query, but often a complex communication 
process. For example, we learn of the option space by seeing the results 
to our initial queries and then typically refine our usage of the 
vocabulary.

"..Language is a living organism that adapts to the development and the 
trends of society as a whole."[1]
