. . . . "Table 5 describes the analysis of signal (a) over the 3 frames that are mapped to DBPO properties. For each property and dataset, we computed the amount of available assertions and reported the gain relative to the fact extraction datasets. Although we considered the whole Italian DBpedia KB in these calculations, we observe that it has a generally low coverage with respect to the analysed properties, probably due to missing ontology mappings. For instance, the amount of assertions is always zero if we analyse the use case subset only, as no specific relevant mappings (e.g., Carriera_sportivo 29 to careerStation) currently exist. We view this as a major achievement, since our automatic approach also serves as a substitute for the manual mapping procedure." . . . . "2019-11-10T18:05:11+01:00"^^ . .
