I am trying to understand the stategy or idea for building a large map of related / common keywords or tags. Use as an example; If you go to "Python" and type, you will get all the tags that have that word, but there can not be any tags that can be related closely (WSGI, Google's app engine, flying, e.t.c).
In line with my question, how can you create a spatial map that can be asked by searching to find nearby tags / keywords, depending on their weight, can be ordered? But then how to store the tag, a potentially large number of tag weighs tag foo and still makes the system responsive?
I have already seen this Google Take-Talk by David Weinberger which is a great technical thing that has started thinking about me.
Check clustering concepts from O'Reilly.
