Ontology-based Knowledge in Interactive Maintenance Guide

This paper describes 4M, a language technology research project where a dialogue system is applied on a mobile platform in a maintenance job scenario. The human-machine interface uses speech synthesis and recognition, assisted with a hypertext display. We describe a modular agent architecture, composed of independent program components which are implemented by or communicate using ontology programming techniques. Domain content and lingware are developed and shared using standard Web ontology formats and ontology-aware offline tools. A contribution of the project is the attention paid to standardization to help provide the system with new content and to migrate it to new domains, languages and purposes
