English abstract:
Crowdsourcing systems of the future (e.g., social compute Units -- SCUs,collective adaptive systems) promise to support processing of richer and more complex tasks, such as software development. This presupposes deploying ad-hoc assembled teams of human and machine services that actively collaborate and communicate among each other, exchanging different artifacts and jointly processing them. Major challenges in such environments include team formation and adaptation, task splitting and aggregation, and runtime management of data flow and dependencies, collaboration patterns and coordination mechanisms. These challenges can be somewhat alleviated by delegating the responsibility and the know-how needed for these duties to the participating crowd members, while indirectly controlling and stimulating them through appropriate incentive mechanisms.

In this paper we present a novel, artifact-centric approach for modeling and deploying incentives in rich crowdsourcing environments. Artifact's lifecycle model is augmented with incentive mechanisms to create encapsulated units that can be offered to the crowd for processing. The incentive mechanisms are adaptive and constantly advertised to the crowd to drive the processing in the envisioned direction and tackle the aforementioned challenges. They are designed to promote teamwork, and to support time and data-dependencies.
