I just came across an article by Clay Shirky that relates ontology and delicious. I found it a little bit naive, with regard to ontology, but it does present an interesting example of the problems of seeing the world through the lens of General Systems Theory. AOP has found that out, sort of, in a more painful way. See Michael Jacksonbook for an insightful critique of both systems and object oriented modeling paradigms.
Shirky´s observations are on the same path of my quick note. I was amazed that it was the topic of an IEEE Spectrum article (see previous post). Shirky article is a nice way of explanning delicious from the point of view of what is tagging. I am sure we are scratching the possibilities.
I also agree with Shirky in the case of tagging, as more tags you get the better you will be. If this is right, it is yet another evidence that folksonomy, or tagging by the masses is the way to go.
Choosing the tag, tagging, on delicious, I came across an interesting piece by Rashmi on cognitive processes behind tagging. I just glimpsed over it. However from there I found out a very very interesting concept: Game-like Elicitation Methods. I need to look at it more closely.
By the way. I found a nice link for those that like to read more about ontology.
