School of Everything subjects are a folksonomy. There is no imposed structure or hierarchy - we take whatever we are given!
Instead of an imposed structure, we look for similarities in the way subjects are used around the site. Whenever a teacher tells which subjects they teach, we assume that there is some connection between the terms they provide us. We locate similarities using simple normalised co-occurrence analysis.
URLs in the subjects area of the site are constructed as follows:
http://schoolofeverything.com/subject/tai-chi/london/teaching
- tai-chi can be replaced with any subject in the vocabulary
- london can be replaced with any location alias (http://www.schoolofeverything.com/sitemap/location) or 'all'
- teaching is the default content type returned; learning, lessons and scrapbook are also possible
Results displayed at these locations include similar subjects for our more popular subjects. The other subjects can be seen in the 'Also showing' text at the bottom of the page.
Content Markup
More and more content on School of Everything will be using RDFa markup. Currently our subjects described in an inline SKOS RDFa graph on each page.
