Apolda: A Practical Tool for Semantic Annotation

In this paper we give an overview of methods to find representations of ontology defined concepts in texts. We distinguish two approaches: lexicon-based methods and approaches using lexicalized ontologies. We focus on the latter method and describe the problems and choices that have to be made if this approach is put to work. Finally we describe an open-source tool that implements the lexicalized ontology approach along with two examples of its applicability in a practical context.
