The approach to use only tags for interest determination brings some new questions.
Not only that even tags that won’t get useable data from encyclopedias are maybe good to use in other context, e.g. all the geo-information provided via tag can be used to get data about users locations when providing data.
But what nature can tags be?
- numbers e.g. years
- ratings
- recommenddations for other users beginning with “for:” (delicious)
- reminders like toRead, toDo (and similar noptations 2Read)
- opinions e.g. fun, funny, humor
- geography data starting with “geo:” or “ge:”
- mechanical tags with prefixes like “filetype:”
Is this all? Are there more then this? Does anyone bring it into order? Maybe Metatagging, will do but do you know?
Organising tags matt calls herding tags, nice comparison.
To find more inspriation maybe a look at the microformats opens another window …
WikiPedia is also working on how to get microformats integrated in the mediawiki-software.
very interesting to read for that topic: Danah Boyds report “Position Paper, Tagging, Taxonomy, Flickr, Article, ToRead” and in addition Gene Smith with “Taxonomy of tagging systems”
