The Ontology registry system is developed to collect, manage, and compare ontological informa-tion for integrating global observation data. Data sharing and data service such as support of metadata deign, structudng of data contents, support of text mining are applied for better use of data as data interop-erability. Semantic network dictionary and gazetteers are constructed as a trans-disciplinary dictionary. On-tological information is added to the system by digitalizing text based dictionaries, developing "knowledge writing tool" for experts, and extracting semantic relations from authodtative documents with natural lan-guage processing technique. The system is developed to collect lexicographic ontology and geographic ontology.
