A knowledge based approach to Information Extraction for semantic interoperability in the archaeology domain
The article presents a method for automatic semantic indexing of archaeological grey literature reports using empirical (rule based) Information Extraction techniques in combination with domain specific knowledge organization systems. The semantic annotation system (OPTIMA) performs the tasks of Named Entity Recognition, Relation Extraction, Negation Detection, and Word Sense Disambiguation using hand crafted rules and terminological resources for associating contextual abstractions with classes of the standard ontology CIDOC Conceptual Reference Model (CRM) for cultural heritage and its archaeological extension, CRM EH.
