The Wikipedia itself allows the categorisation of pages. Each page may belong to at least one category which reflects the topic and classes that are directly related to the subject of the page (Wikipedia, 2009). For example, the article about Student’s t-test belongs to the categories Statistical tests, Statistical methods and Parametric statistics. It is possible to build hierarchies of categories, for example all three categories are part of the category Statistics.
