Providing a tag recommendation service in your Web 2.0 application helps to organise all kind of content in a more effective way.

Especially inside companies tags can be a valuable additional resource for a better knowledge management or more efficient search services. Throughout organisations most often controlled vocabularies (product taxonomies, skills databases, technology lists etc.) exist which can be used for a tag-recommender.

TagRecommender BETA is realised through a mash-up of text analysis and the use of a domain ontology. Therefore it´s a prototype showing how tag recommenders can work efficiently in defined areas like each company usually covers.
