Semantic interoperability is the ability of different information systems and organizations to exchange data and information in a meaningful and efficient way, so that the shared information can be easily understood and used by all parties involved. This requires not only technical compatibility, but also agreement on the meaning and interpretation of the data being exchanged. Semantic interoperability is crucial in fields such as healthcare, information technology, and data sharing, where accurate and consistent data exchange is essential for decision-making and collaboration. Researchers in this area focus on developing standards, protocols, and tools that promote seamless communication and exchange of data across different systems and organizations.
