Active Knowledge Support for Integrated Operations (AKSIO) is a work process-enabled knowledge management system that supports experience transfer in operations of offshore oilfields. The system provides timely and contextual knowledge for work processes. Experience reports are processed and annotated by experts and linked to various resources and specialist knowledge networks. The system allows retrieval of experience reports through the support of a domain ontology. Core functionality of the system is provided by careful application of Semantic Web technology, including ontology-based annotation and contextual ontology-driven retrieval of content. The purpose of this chapter is to demonstrate how Semantic Web technology is an effective enabler of improved knowledge management processes in corporate environments.
