. . . . "First, we observe a lack of ontology property usage in 4 out of 7 classes, probably due to missing mappings between Wikipedia template attributes and DBPO. On the other hand, the ontology properties have a more homogenous distribution compared to the raw ones: this serves as an expected proof of concept, since the main purpose of DBPO and the ontology mappings is to merge heterogenous and multilingual Wikipedia template attributes into a unique representation. In average, most raw properties are concentrated below coverage and frequency threshold values of 0.8 and 4 respectively: this means that roughly 80% of them have a significantly low usage, further highlighted by the log scale. While ontology properties are better distributed, most still do not reach a high coverage/frequency tradeoff, except for SoccerPlayer, which benefits from both rich data (cf. Section 3) and mappings. 28" . . . . "2019-11-10T18:05:11+01:00"^^ . .
