abstract = {NaturalOWL is an open-source natural language generation engine written in Java. It produces descriptions of individuals (e.g., items for sale, museum exhibits) and classes (e.g., types of exhibits) in English and Greek from OWL DL ontologies. The ontologies must have been annotated in RDF with linguistic and user modeling resources. We demonstrate a plug-in for Protégé that can be used to produce these resources and to generate texts by invoking NaturalOWL. We also demonstrate how NaturalOWL can be used by robotic avatars in Second Life to describe the exhibits of virtual museums. NaturalOWL demonstrates the benefits of Natural Language Generation (NLG) on the Semantic Web. Organizations that need to publish information about objects, such as exhibits or products, can publish OWL ontologies instead of texts. NLG engines, embedded in browsers or Web servers, can then render the ontologies in multiple natural languages, whereas computer programs may access the ontologies directly.

abstract = {We present the dialogue system of a robot that has been developed to serve as a museum guide. The robot interacts with human visitors in natural language, receiving instructions and providing information about the exhibits. Moreover, being mobile, it physically approaches the exhibits it provides information about. Although the robotic platform contains many modules, including navigation, speech recognition and synthesis, our focus in this paper is the dialogue system, which supports the sessions between humans and the robot, as well as the natural language generation engine, which generates the text to be spoken. Both modules are closely intertwined and depend on an ontology represented in OWL. The robot supports dialogues in both English and Greek.

abstract = {Metadata interoperability is an active research area, especially for cultural heritage collections, which consist of heterogeneous objects described by a variety of metadata schemas. In this paper we propose an ontology-based metadata interoperability approach, which exploits, in an optimal way, the semantics of metadata schemas. In particular, we propose the use of CIDOC/CRM ontology as a mediating schema and present a methodology for mapping DC Type Vocabulary to CIDOC/CRM, demonstrating a real-world effort for ontology-based metadata integration.},
