An Ontology for Human-Machine Computation Workflow Specification

Lately, a focus has been given to the re-usability of workflow definitions and to flexible and re-usable workflow components, culminating with approaches that harness the benefits of the enriched semantics provided by ontologies. Following this trend and the needs of multiple application domains, such as micro-task crowdsourcing and ambient assisted living, of incorporating cooperation between the efforts of human and machine entities, this paper proposes an ontology and process for the definition, instantiation and execution of semantically enriched workflows.
