. . . . . . . . "The authors stated that they focused on DBpedia \"as a representative data set for the broader Web of Data\"; I largely disagree with that for the following reasons: (1) not all LD sources are produced by following a transformation/mapping process like DBpedia one, and the types of errors that happen in a specific LD source heavily depend both on the intrinsic quality of the source and on the possible translation process to RDF; (2) DBpedia is very general in coverage of topics, while LD sources (and their possible quality issues) can be very specific to a given domain; as a consequence, the capability of an experts' or workers' crowd to identify and assess LD quality issues is highly influenced by the domain/coverage of the source. Therefore, I'd recommend to soften the claims of generality of the presented results and to clearly state that they are \"proved\" only on DBpedia. I'm sure the authors can speculate to what extent those results can be considered general, but at the present moment I believe they cannot affirm that they fully addressed the research questions as they are introduced." .
