Hi all,

A similar system (for Object Coreference): 
http://iws.seu.edu.cn/services/ObjectCoref/


The "Core" coreference is based on owl:sameAs and IFP, and the "Extension" is based on label/local name and ranking strategy.

It provides evidence for coreference (owl:sameAs triples, IFP property values, and in the case of "extension", label/local name as well as similarity).

Best regards,

Yuzhong Qu
