Abstract:

The polar region is currently a focus of worldwide attention and an area of active research. The rapid
growth of multidisciplinary polar science data has led to the need for effective management of these data and
for the provision of intelligent data services. To overcome problems such as incomplete and/or inaccurate
data retrievals in a data sharing platform based on key words and subjects, this paper proposes a polar science
data ontology library based on spatial relations. First, the method of construction of polar science data
ontology is discussed in terms of spatial relations by studying the semantic concepts, attributes, and relations
of polar science data. This is undertaken in conjunction with the formal representation model of spatial relations
in ontology construction, based on the metadatabase of the Chinese National Arctic and Antarctic Data
Center, and the concept of ontology. Then, a general framework of polar ontology is designed with consideration
of spatial relations. Finally, a polar science data ontology library is built using ontology construction
tools.

Key words: polar science data, spatial relations, ontology, protégé
