Re: [Sigia-l] tagging versus taxonomy
Answering your questions - I am talking about fundamental teoretical
differences between those two models of classifying thigs and their
consequences in the cognitive process of both classifying and finding
something previously classified. With tags you can specify compound
terms like 'tag1 and tag2 and tag3' while with taxonomy, as I
understand it, you would need a separate name for each of those terms.
In other words taxonomy is a language where you need a word for
everything while tags are words plus some rules about how to combine
I don't remember the exact number of such terms - but a simple
inductive proof that there are more than 2^n might go like this:
1. let's assume the inductive hypothesis for n
2. when we add one more term we can combine it with each of the
previous terms so we have more than 2^n the previous terms plus the
more than 2^n new terms => more than 2^(n+1) terms in total q.e.d
What I would like to stress here is that the difference in
descriptivness is expotential - that's huge.
