I can only plead what I hope is a unique set of circumstances including, inter alia, parenthood, client work, and an unusually demanding semester of teaching, all of which kept me from writing. Or, rather, kept me from re-reading. I've always known that there's a difference between what I post here and what I post on Many-to-Many [http://corante.com/many/] or Tagsonomy [http://www.tagsonomy.com/] weblogs (a group weblog on tagging and folksonomy), but never knew what the difference was. Now I know. The stuff I post here is not just something I've written, but something I've read and re-read a dozen times. It's an argument I think will be useful beyond a 72 hour time horizon. And the re-reading time is what went missing this spring. There's value in each way of working -- writing quick vs. writing slow -- and this list is for the slow writing. This post is different in another way -- because it's taken from two slide-heavy talks I gave this spring on categorization and tagging, the only way to send it in email would be HTML email, and if I were going to do that, I could just give you the link. Which is what I'm going to do. I include the intro below, so you can see what the piece is about, but the full text and pictures are on the Web. And thanks, as always, for reading. -clay * Essay ============================================================= Ontology is Overrated -- Categories, Links, and Tags http://shirky.com/writings/ontology_overrated.html Intro: Today I want to talk about categorization, and I want to convince you that a lot of what we think we know about categorization is wrong. In particular, I want to convince you that many of the ways we're attempting to apply categorization to the electronic world are actually a bad fit, because we've adopted habits of mind that are left over from earlier strategies. I also want to convince you that what we're seeing when we see the Web is actually a radical break with previous categorization strategies, rather than an extension of them. The second part of the talk is more speculative, because it is often the case that old systems get broken before people know what's going to take their place. (Anyone watching the music industry can see this at work today.) That's what I think is happening with categorization. What I think is coming instead are much more organic ways of organizing information than our current categorization schemes allow, based on two units -- the link, which can point to anything, and the tag, which is a way of attaching labels to links. The strategy of tagging -- free-form labeling, without regard to categorical constraints -- seems like a recipe for disaster, but as the Web has shown us, you can extract a surprising amount of value from big messy data sets.
