Semantic Annotation from Social Data.

Abstract. Folksonomies can be viewed as large sources of informal se-mantics. Folksonomy tags can be interpreted as concepts that can be extracted from the social data and used as a basis for creating semantic structures. In the folksonomy the connection between these concepts and the tagged resources are explicit. However, to effectively use the extracted conceptual structures it is important to be able to find connections be-tween the concepts and not only the already tagged documents, but also new documents that have not previously been seen. Thus, we present in this paper an automatic approach for annotating documents with con-cepts extracted from social data. This is based on representing each tag’s semantics with a tag signature. The tag signature is then used to generate the annotations of documents. We present an evaluation of the approach which shows promising results towards automatic annotation of textual documents. 1
