Online Resource Sharing tools like flickr, delicious or citeulike use tags to categorize their content. A tag consists of a concatenated string arbitrarily chosen by the user. It includes no structure and no semantic information. In the course of time, some users tried ot use separators or case sensitive writing to integrate more information in tags.
The idea of this masterthesis is to enrich tags with semantic information. A prototype should be developed which allows the user to use structured tags in addition to „normal“ tags. Therefore a user has the possibility to organize his content in a better way. To encourage the user to use structured tags, the prototype provides suggestions of structured tags through the tagging-process.
