An OWL-based extensible transcoding system for mobile multi-devices

Due to the rapid Internet development, an answer to the challenging question of how to automatically convert heterogeneous information into the desired XML format that can be accepted by a designated device is urgently requested. In this paper, we propose an OWL-based extensible transcoding system (OETS) which is based on an extensible transcoding policy infrastructure, with a hierarchical structure of ontologies, and can automatically render an HTML document in mobile devices. In order to create common knowledge of OETS, we develop two top level ontologies: procedural sensor/effector ontology (PSEO) and markup file taxonomy ontology (MFTO). PSEO combines with situated logic to support sensor/effector procedures attached to an ontology class, while MFTO supports the markup file and structural components classification. Developers can exploit the extensible transcoding capability of OETS to satisfy various layout-specific structures of HTML pages by providing dedicated domain ontologies.
