The invention provides a semantics-based registration information security officer authentication capability evaluation method and system and relates to the field of information security. The method comprises the steps of establishing an information security knowledge system ontology library, establishing a knowledge association recommendation, establishing a knowledge association path recommendation based on the ontology library, a knowledge point association path between knowledge classes and an association path between knowledge bodies, conducting evaluation on students, giving a general statistical analysis semantics-based analysis result and forming an electronic report. The system comprises an authentication management module, an authentication examination module, a capability assessment management module and a system management module. According to the method and system, semantic association between evaluated knowledge points is considered in all the steps from knowledge system establishment to evaluation result analysis, so that the mechanical properties, caused by automatic processing, of evaluation are reduced, evaluation efficiency and quality are improved, the reasonability of a final evaluation result is guaranteed, and then the purpose of capability evaluation is better achieved.
