Not a troll, exactly. It is a rehearsal. The TAG has to work the http range issue. The book I referenced a week or so ago gave me some ideas about this, particularly that some of the problems of these definitions may be treatable given a different logic (ie, quantum vs boolean logic). It is precisely that there are multiple spaces and this introduces ambiguity to terms and elements. Why do we care? Query on "Michael Jackson" and "suit". For this example, say you get back a lot of articles about his legal woes and descriptions of his warddrobe. That is an example of an ambiguous term. It exists simultaneously in different semantic spaces. As the book points out, search engines can use combinations of positive and negative terms to determine which space is 'meant'. It is a geometric approach to the problem. The notions of information spaces suggest that a geometric space is a realistic approach. Remember, the reader is blind to the writer. My math stinks, so I come to the smart people with this idea. len From: Bob Foster [mailto:bob@o...] Wow, talk about trolling! ;-} How about we back up to: why do we care? It's those damn namespaces. Suppose there were no namespaces. Suppose instead of namespaces, there were only globally unique names. Because it's simpler to use an authority than to pretend we can calculate a globally unique name, suppose we use inverted domain names. That is, for a registered domain "x.y", its globally unique names are constructed with the prefix "y.x". Then we might have "com.intergraph.bullard.len" as a globally unique name. End of story. No namespaces. Nobody ever asks if "com.intergraph" is a "resource", whatever that is, because it's patently obvious it isn't. We don't need namespaces and never did. Imagine how many person-hours would have been saved if we didn't have them. ;-} Bob Foster Bullard, Claude L (Len) wrote: > That's the critical observation for this and many other > threads that rely on ontological commitment to sustain > communications. > > Would anyone care to compare that to URIs as a unit of > information: > > 1.
