Query: Ontology Service Center: a datahub for ontology application   With the growth of data-oriented research in humanities, a large number of
research datasets have been created and published through web services.
However, how to discover, integrate and reuse these distributed heterogeneous
research datasets is a challenging task. Ontology is the soul between series
digital humanities resources, which provides a good way for people to discover
and understand these datasets. With the release of more and more linked open
data and knowledge bases, a large number of ontologies have been produced at
the same time. These ontologies have different publishing formats, consumption
patterns, and interactions ways, which are not conductive to the users
understanding of the datasets and the reuse of the ontologies. The Ontology
Service Center platform consists of Ontology Query Center and Ontology
Validation Center, mainly using linked data and ontology-based technologies.
The Ontology Query Center realizes the functions of ontology publishing,
querying, data interaction and online browsing, while the Ontology Validation
Center can verify the status of using certain ontologies in the linked
datasets. The empirical part of the paper uses the Confucius portrait as an
example of how OSC can be used in the semantic annotation of images. In a word,
the purpose of this paper is to construct the applied ecology of ontology to
promote the development of knowledge graphs and the spread of ontology.
