ABSTRACT
Objective To analyze the use of the semantic type of the top-level ontology of military medicine in order to find problems with the semantic type framework and make it more scientific and comprehensive.Methods Using data driven method, the frequency with which the semantic type of the top-level ontology of military medicine was used in military medical core concepts was statistically analyzed.Results By ranking the use frequency of the semantic types, the semantic types which had higher or lower frequency, and those that had never been used were analyzed.Conclusion The established semantic type framework of the top-level ontology of military medicine is basically consistent with the expression of military medical knowledge and can be constantly updated and improved with the development of military medicine.
ABSTRACT
Objective To explore a construction method of semantic relations of the top-level ontology of military medicine in order to construct the top-level ontology semantic network.Methods The military medical corpus was selected,and the relationships between the concepts were extracted using text analysis.On the basis of inheriting the semantic relations of UMLS,the special semantic relations of military medicine were added.Results A method of establishing the semantic relations of the top-level ontology of military medicine was proposed,the applicability of which was verified by example of the branch of military medical equipment.Conclusion The proposed method is effective and feasible,which can provide important support to the establishment of top-level semantic networks of military medicine.
ABSTRACT
Objective To explore the construction method of semantic types of military medical ontology and to establish a framework for the semantic types of the top-level ontology of military medicine in order to lay the foundation for the construction of military medical ontology and provide support for knowledge organization, knowledge disclosure and knowledge service of military medical information resources.Methods Using the method of document measurement, the core concept set of military medicine was constructed.On the basis of the framework of the top-level semantic types of Unified Medical Language System(UMLS), the semantic type framework was completed by the combination of bottom-up and top-down modes, using semantic analysis and expert consultation.Results By classifying the same kind of knowledge points of military medicine into one semantic type, the hierarchical structure of the semantic type framework of the top-level ontology of military medicine was obtained.Conclusion The proposed method is effective and practical for the construction of the semantic types of military medical ontology.The established semantic type framework of the top-level ontology of military medicine could reconstruct military medical knowledge and provide the basic framework for the establishment of the semantic relationships of the top-level ontology of military medicine.
