Big Data Management Challenges in SUPERSEDE.

The H2020 SUPERSEDE (www.supersede.eu) project aims to support decision-making in the evolution and adaptation of software services and applications by exploiting end-user feedback and runtime data, with the overall goal of improving the end-users quality of experience (QoE). Such QoE is defined as the overall performance of a system from the point of view of users, which must consider both feedback and runtime data gathered. End-user’s feedback is extracted from online forums, app stores, social networks and novel direct feedback channels, which connect software applications and service users to developers. Runtime data is primarily gathered by monitoring environmental sensors, infrastructures and usage logs. Hereafter, we discuss our solutions for the main data management challenges in SUPERSEDE.
