Abstract:
This paper proposes a web-based application which combines social tagging, enhanced visual representation of a document and the alignment to an open-ended social ontology. More precisely we introduce on the one hand an approach for automatic extraction of document related keywords for indexing and representing document content as an alternative to social tagging. On the other hand a proposal for automatic classification within a social ontology based on the German Wikipedia category taxonomy is proposed. This paper has two main goals: to describe the method of automatic tagging of digital documents and to provide an overview of the algorithmic patterns of lexical chaining that can be applied for topic tracking and –labelling of digital documents.
