F.: Bridging Ontologies and Folksonomies to leverage knowledge sharing on the social web: a brief survey

Social tagging systems have recently became very pop-ular as a means to classify large sets of resources shared among on-line communities over the social Web. However, the folksonomies resulting from the use of these systems re-vealed limitations: tags are ambiguous and their spelling may vary, and folksonomies are difficult to exploit in or-der to retrieve or exchange information. This article com-pares the recent attempts to overcome these limitations and to support the use of folksonomies with formal languages and ontologies from the Semantic Web.
