  sub:paragraph c4o:hasContent "A similar study is discussed in [28] for ontology alignment. McCann and colleagues studied mo- tivators and incentives in ontology alignment. They investigated a combination of volunteer and paid user involvement to validate automatically generated alignments formulated as natural-language questions. While this proposal shares many commonalities with the CrowdMap [33] approach, the evaluation of their solution is based on a much more constrained experiment that did not rely on a real-world labor market- place and associated work force." ;
