Nursing language plays an important role in describing and defining nursing phenomena and nursing actions. There are numerous vocabularies describing nursing diagnoses, interventions, and outcomes in nursing domain. However, lack of a standardized, unified nursing language is considered as a problem for further development of the discipline of nursing. With this background this study was conducted to construct a semantic network based on cross mapping of existing nursing terminologies. specifically NANDA taxonomy I, Omaha system, HHCC. and NIC. which arc recognized as standard terminology by the American Nurses Association. The nursing semantic network was proposed with the cross mapping results based on the UMLS semantic network.
