Context-awareness in the vision of Ubiquitous Computing implies more than just the integration of sensor data into applications. It promises vast benefits from automated sharing and combining of knowledge about current situations. We emphasize the necessity of quality of context (QoC) to enable and improve the automatic rating and processing of context information. We derive requirements for handling and modelling of QoC by analyzing the context provisioning process and show that existing integrations of QoC into context models are not adequate. And we concretize our understanding of QoC by distinguishing between information-inherent QoC and application-dependent considerations.
