The process of writing a résumé is a task where the notion of background knowledge plays an important role. In a résumé there is a lot of interrelated and implicit information. The use of domain ontologies and semantic technologies may provide a valuable help to make evident these interrelations and to make explicit the implicit knowledge. We present a system to automatically produce a semantically annotated résumé exploiting domain knowledge modeled with respect to a domain ontology. Here, semantic technologies and domain ontologies have been used both to help the user during the writing process and to explicitly represent domain knowledge in the final CV.
