In the following we briefly describe contest- based and microtask crowdsourcing, the two crowdsourcing methods studied in this work. http://purl.org/np/RAVX3cU1N5c1pqv0QWCvOGPxBt57xDKF1nxeitXwjbcOw#paragraph http://www.w3.org/1999/02/22-rdf-syntax-ns#type http://purl.org/spar/doco/Paragraph http://purl.org/np/RAVX3cU1N5c1pqv0QWCvOGPxBt57xDKF1nxeitXwjbcOw#provenance http://purl.org/np/RAVX3cU1N5c1pqv0QWCvOGPxBt57xDKF1nxeitXwjbcOw#assertion http://www.w3.org/ns/prov#hadPrimarySource http://dx.doi.org/10.3233/SW-160239 http://purl.org/np/RAVX3cU1N5c1pqv0QWCvOGPxBt57xDKF1nxeitXwjbcOw#assertion http://www.w3.org/ns/prov#wasAttributedTo https://orcid.org/0000-0003-0530-4305 http://purl.org/np/RAVX3cU1N5c1pqv0QWCvOGPxBt57xDKF1nxeitXwjbcOw#pubinfo http://purl.org/np/RAVX3cU1N5c1pqv0QWCvOGPxBt57xDKF1nxeitXwjbcOw http://purl.org/dc/terms/created 2019-11-07T12:47:11+01:00 http://purl.org/np/RAVX3cU1N5c1pqv0QWCvOGPxBt57xDKF1nxeitXwjbcOw http://purl.org/pav/createdBy https://orcid.org/0000-0002-7114-6459
