A lot of the conversation thats going on now aboutcategorization starts at a second step -- since categorization is agood way to organize the world, we should. Not because thats what they thought was true about the world, but because they dont have the staff to reshelve all the books. It forces categorizers to guess what their users are thinking, and to make predictions about the future.
Woe betide the person who utters sentence b when what they mean is sentence a. Were early in the use of tags, so we dont yet have large, long-lived data sets to look at, but they are being built up quickly, and were just figuring out how to extract novel value from whole collections of tags. The graph at the upper right, by contrast, shows the tags for a page detailing how to embed standing searches in gmail.
Therefore, i can use predicate logic to come up with recommendations -- users run software, software runs on operating systems, osx is a type of operating system -- and then say here mr. So if you mistakenly thinkthat books and literature are entertainment, well put a little flag upso we can set you right, but to see those links, you have to go towhere they are. They said, get out ofhere with that crazy talk.
In environments where theres no authority and no force thatcan be applied to the user, its very difficult to support the voodoo styleof organization. This looks relatively simple with the applemacosx example, but when we start to expand to other groups of related words, like movies, film, and cinema,the case for the thesaurus becomes much less clear. These are the act of organizing a collection of entities, whether things or concepts, into related groups.
Instead of having massive categorizations and then specialty categorization, were going to have a spectrum between them, based on the size and make-up of various tagging groups. The essence of a book isnt the ideas it contains. As the web expanded, the yahoo list grew into a hierarchy with categories.
Minnesota! Forget it, were notgoing to optimize for one-offs like that. But they either had no way of reflecting that debate or they decided not to expose it to the users. You will not find it, even though, as an organizing principle for a large group of people, that word matters enormously. Theamount of people infrastructure thats hidden in a working system like dsm iv is a big part of what makes this sort of categorization work. But in a world where enough points of view are likely to provide some commonality, the aggregate signal loss falls with scale in tagging systems, while it grows with scale in systems with single points of view.
The solution to this sort of signal loss is growth. So if you mistakenly thinkthat books and literature are entertainment, well put a little flag upso we can set you right, but to see those links, you have to go towhere they are. A professional cataloguer would look at this tag in horror -- this is context-dependent and temporary. People have been freaking out about the virtuality of data for decades, and youd think wed have internalized the obvious truth there is no shelf. The other essential value of market logic is that individual differences dont have to be homogenized.
Its tempting to think that the classification schemes that libraries have optimized for in the past can be extended in an uncomplicated way into the digital world. Towhich one can only respond -- whats real? Yahoo is saying we understandbetter than you how the world is organized, because we are trained professionals. The web is mainly notable for two things -- the way it ignored most of the theories of hypertext and rich metadata, and how much better it works than any of the proposed alternatives. First published november 5, 2004 on the networks, economics, and culturemailing list. But the first step is to ask thecritical question is categorization a good idea? We can see, fromthe yahoo versus google example, that there are a number of caseswhere you get significant value out of categorizing.
Tags are important mainly for what they leave out. We are moving away from binary categorization -- books either are or are not entertainment -- and into this probabilistic world, where n of users think books are entertainment. The written versionis a heavily edited concatenation of those two talks. Market logic allows many distinct points of view to co-exist, because it allows individuals to preserve their point of view, even in the face of general disagreement. The chart shows a great variability in tagging strategies among the various users. In a world where publishing is expensive, the act of publishing is also a statement of quality -- the filter comes before the publication. Now we have this ontologically managed list of whats out there. Its for people who are keeping track of their urls for themselves, but who are willing to share globally a view of what theyre doing, creating an aggregate view of all users bookmarks, as well as a personal view for each user. The sense of ontology there is something like an explicit specification of a conceptualization. Once a link has been tagged more than once, though, users can view or ignore the odd tags as it suits them, and the decision about which tags to use comes after the links have been tagged, not before.23 Jan 2017 ...
