A Domain Security Ontology Network Constructing and Hardening Technology

In order to solve the problem brought from the enormous policy texts and the complex management in the social insurance field, the article uses ontology as the way of representing and storing the knowledge. The article first constructed the framework of the ontology through manual work to ensure the relative accuracy of the ontology structure. Then it achieved the automatic ontology expansion based on the inclusion relationship of the property sets or the operational object sets. The experiment result indicates that this ontology automatic construction process can help the field experts to construct the social insurance ontology effectively, and it is also a considerable reference for the construction of the ontology in other fields.
