"Millions of Games"- example of structured tagging

Search Engine Watch,a web site dedicated to the search engine industry, has had very little good to say about folksonomy-type tagging. In folksonomy tagging users annotate pages, images and other web content with descriptive keywords without the aid of controlled vocabulary. For their view on this controversy see "Tagging Not Likely The Killer Solution For Search"

Recently, Search Engine Watch cited an example of a site called Millions of Games, a search tool for finding games on the Internet. Unlike other user-tagged sites, the developers of this site provide controlled vocabulary categories to assist users assign unambiguous category tags.

Search Engine Watch comments: "Rather than allowing users to tag anything with any words they fancy, [we think] adding structure, defining a mutually agreeable taxonomy and relying less on idiosyncratic language seems like a very promising approach. Millions of Games is an example of a good start to a more useful form of structured tagging. See "Where Tagging Works: Searching for a Good Game"
