Hi All, i got confused between the usage of the two properties "instance of " (P31<https://www.wikidata.org/wiki/Property:P31>) and "is a list of" (P360 <https://www.wikidata.org/wiki/Property:P360>) for example we can find that only 2K entities are listed as Person<http://wikidata.org/entity/Q215627> class using P31 property while the rest are mainly P360 and P107 numbers in details: 93979 <http://www.wikidata.org/entity/P107> 2171 <http://www.wikidata.org/entity/P31> 60024 <http://www.wikidata.org/entity/P360> Thanks Regards ------------------------------------------------- Hady El-Sahar Research Assistant Center of Informatics Sciences | Nile University<http://nileuniversity.edu.eg/>
