The ontology describing the domain of interest is defined using a set of concepts, their properties, their relations and the associated cardinalities. The approach consists of locating and then annotating concept instances and their semantic relations. The locating step combines existing annotation approaches in order to locate instances in the text. The annotation step exploits a set of metadata and a set of logical rule patterns which are automatically instanciated from the doma...
