Abstract: Ontology is a collection of terms describing a field, which has been widely used in digital
humanities research. However, there are few public released ontologies that can be obtained and used,
which seriously affects the sharing and interaction between digital humanities resources. The paper aims
to provide an online ontology retrieval, interaction and reuse platform for digital humanities research by
constructing an ontology service center. First of all, the paper expounds the design ideas and technical
implementation path of the ontology data storage structure from the perspective of data storage. Secondly,
it discusses the deep-level application of ontology in three parts: serialization conversion, visual
presentation and interface calling of ontology. Finally, the paper detailed the application prospects of
ontology service from the perspectives of ontology publishing and image resource semantic annotation
in digital humanities research. Of course, the ontology service center needs the participation and
maintenance of more scholars. Only by effectively publishing and efficiently using ontology resources
can we build a good ontology application ecosystem.
