When a worker accepts a microtask or HIT, she is presented with a table that con- tains triples associated to an RDF resource, as shown in Figure 1. For each triple, the worker determines whether the triple is ’incorrect’ with respect to a fixed set of quality issues Q (cf. Section 2): object incorrectly/incompletely extracted, datatype incorrectly extracted or incorrect link, abbreviated as ‘Value’, ‘datatype’, and ‘Link’, respectively. Once the worker has assessed all the triples within a microtask, she proceeds to submit the HIT. Consistently with the Find stage implemented with a contest, the outcome of the microtasks corresponds to a set of triples T judged as ‘incorrect’ by workers and classified according to the detected quality issues in Q. http://purl.org/np/RA7W2U3aq0osk5g-6hExeg9-AzOMnEGra_6pyUNYPEd68#paragraph http://www.w3.org/1999/02/22-rdf-syntax-ns#type http://purl.org/spar/doco/Paragraph http://purl.org/np/RA7W2U3aq0osk5g-6hExeg9-AzOMnEGra_6pyUNYPEd68#provenance http://purl.org/np/RA7W2U3aq0osk5g-6hExeg9-AzOMnEGra_6pyUNYPEd68#assertion http://www.w3.org/ns/prov#hadPrimarySource http://dx.doi.org/10.3233/SW-160239 http://purl.org/np/RA7W2U3aq0osk5g-6hExeg9-AzOMnEGra_6pyUNYPEd68#assertion http://www.w3.org/ns/prov#wasAttributedTo https://orcid.org/0000-0003-0530-4305 http://purl.org/np/RA7W2U3aq0osk5g-6hExeg9-AzOMnEGra_6pyUNYPEd68#pubinfo http://purl.org/np/RA7W2U3aq0osk5g-6hExeg9-AzOMnEGra_6pyUNYPEd68 http://purl.org/dc/terms/created 2019-11-08T18:05:11+01:00 http://purl.org/np/RA7W2U3aq0osk5g-6hExeg9-AzOMnEGra_6pyUNYPEd68 http://purl.org/pav/createdBy https://orcid.org/0000-0002-7114-6459
