Resource and Agreement Management in Dynamic Crowdcomputing Environments

Abstract—Open Web-based and social platforms dramatically influence models of work. Today, there is an increasing interest in outsourcing tasks to crowdsourcing environments that guarantee professional processing. The challenge is to gain the customer’s confidence by organizing the crowd’s mixture of capabilities and structure to become reliable. This work outlines the requirements for a reliable management in crowdcomputing environments. For that purpose, distinguished crowd members act as responsible points of reference. These members mediate the crowd’s workforce, settle agreements, organize activities, schedule tasks, and monitor behavior. At the center of this work we provide a hard/soft constraints scheduling algorithm that integrates existing agreement models for service-oriented systems with crowdcomputing environments. We outline an architecture that monitors the capabilities of crowd members, triggers agreement violations, and deploys counteractions to compensate se...
