. . . . "While looking at the language-tagged strings in “English” (in RDF @en), Figure 6b shows that the experts perform very well when discerning whether a given value is an English text or not. The crowd was less successful in the following two situations: (i) the value corresponded to a number and the remaining data was specified in English, e.g., (St. Louis School Hong Kong, founded, 1864); and (ii) the value was a text without special characters, but in a different language than English, for example German (Woellersdorf-Stein abrueckl, Art, Marktgemeinde). The performance of both crowdsourcing approaches for the remaining datatypes were similar or not relevant due the low number of triples processed." . . . . "2019-09-20T18:05:11+01:00"^^ . .
