Semantic Compliance in Complex Enterprise Information Systems. Large organisations have invested heavily to reduce the number of dependent information systems they support. Larger integrated systems should provide increased information reach and better coordination of activities. However there are major problems in practice - integration requires common meaning and context. Information-sharing within cooperating organisations is improved by enforcing compliance of databases with a master model. ....Semantic Compliance in Complex Enterprise Information Systems. Large organisations have invested heavily to reduce the number of dependent information systems they support. Larger integrated systems should provide increased information reach and better coordination of activities. However there are major problems in practice - integration requires common meaning and context. Information-sharing within cooperating organisations is improved by enforcing compliance of databases with a master model. Our research refines, extends and tests an approach for semantic compliance checking based on mathematical category theory. It investigates structures that help detect irregular data. The research uses models from NSW Health. Outcomes include improved processes and software for checking compliance and data anomalies.Read moreRead less
