Ying WANG, Zhixiong ZHANG, Hui SUN & Feng LEI / A method of semantic representation and 115
organization of the historic knowledge on contemporary China
3, to represent the details of historical events, the ontology defines datatype properties including
label, alternative label, literal description, and object properties including parent event, subevent,
related people, related institution, related event, occurrence time, occurrence place, etc. Thirdly,
we defined property restrictions, for example, the parent event property and subevent property are
inverse and transitive, the label property and nationality property are functional. The details of the
historical ontology can be seen in the paper (Sun & Lei, 2014).
