Abstract— Student Portal Management System. The paper describes the Knowledge Management System (KMS) about military universities (MilUNI), mostly in the NATO environment, but it also includes all European countries. The goal of the MilUNI is to support the cooperation among universities in education, research, and the staff and students exchange. The KMS is based on the Topic Maps theory using the AToM (Aion Topic Maps engine) software. Special attention is paid to the ontology design, Knowledge Base (KB) development, and application processing when using the KMS. The KMS includes the KB with interface for administrator, < Final Year Projects > architect, and editor and the Knowledge Portal for user access. The search procedures in the KMS are mentioned. The paper concludes with suggestions for the further development of the system.
