Problem summary

The user wants to find more data in the same category and/or contribute data in the same category



  • Use when the content on your website is possibly mapped into multiple categories and does not necessarily only fit into one hierarchical category.
  • Use when you want users to contribute data to your website and let them organize their contributed data themselves.


Let the contributers of information on your website add keywords (tags) to the content they submit. These keywords are then transformed into links that leads to tag pages; listing all other contributions for that tag (category).


Tags are relevant keywords associated with or assigned to a piece of information. Tags are often used on social websites, where users can upload their own content. Here, tags are used to let users organize and categorize their own data in the public sphere. In this way, tags can be seen as a bottom-up categorization of data rather than a top-down categorization of data, where the creators of the site define the hierarchy data is submitted to.

    “Tags are relevant keywords associated with or assigned to a piece of information.” The problem is, who chooses when a certain tag ís indeed relevant and when it isn’t. Using the tag “css” for every article that has the word css in it might just result in 300 articles with the same tag attached to it. But if we only take those articles that are specifically about css, we might get a nice small list, containing for css articles, but not the one I was looking for. A Google like search system, based on clicks for example, and a well chosen list of “relevant articles”, maybe supported by “other people who liked this article also liked this and that”, will do the job better. I don’t like tags.
