This paper proposes an innovative framework for knowledge management in service-oriented systems. An important novelty of our framework is that it allows for automatic instance level evolution of the knowledge base and that it integrates conceptual level knowledge base evolution with the overall service-oriented system framework. In the paper, we identify several opportunities that have arisen in the field of knowledge management with the wider acceptance of SOA and its technology stack, and we present a framework that addresses these opportunities. We focus on ontology-based knowledge management systems, which have become one of the most important technologies for implementation of knowledge management systems. The framework reduces the required input for knowledge management by knowledge engineers, increases information completeness in the knowledge base and provides a simple way for storing more up-to-date information in the knowledge base.
