The synchronization of the business processes and business vocabulary allows to increase the effectiveness in the business process management, eliminate the inconsistencies in the models and enables users to represent real world processes adequately. The proposed method allows synchronizing Business Process Model and Notation process models and Semantic Business Vocabulary and Rules business vocabulary in an automatic manner. The extraction of the elements of the business vocabulary is based on the Stanford POS Tagger method which is adapted to the peculiarity of the business process models. The paper represents the main principles of the synchronization method and the results of its evaluation performing the practical experiment. The defined quality criteria (inner compatibility of business process model, automated extraction of business vocabulary, completeness of obtained business vocabulary, validity of obtained business vocabulary and adequacy to domain) reveal the main advantages of the proposed method.
