Abstract
How can intertextual relations be formalized and annotated? What would be a coherent category system of intertextuality and which formalization is suitable to make it computable while not losing its expressiveness. Against the backdrop of the most influential classical theories of intertextuality, the article does not aim for an automatic detection of intertextual relations like many other digital humanities approaches did before, but suggests a formal and expandable model of the core of intertextuality with the means of description logic, i.e. it models relations and types of entities being related by them in a machine readable RDF format. The utilization of this theory-driven model is demonstrated by several examples of intertextual relations as discussed in literary studies.
