Disclosed are a method and system for performing regression tests in a state-dependent data processing environment where data are processed by means of at least one function having a signature of defined parameters and corresponding values. A regression test is performed using at least one pre-determined set of test data and one pre-recorded function test case corresponding to said signatures and being used to execute said at least one pre-recorded function test case. The proposed mechanism particularly comprises the step of adapting said at least one function test case or said at least one set of test data to any changed signatures caused by a state transition of said data processing system. The mechanism thus provides automated regression tests in such a data processing environment and enables re-execution of a regression test in a changed context of the underlying data processing environment.

Systems, methods and computer-readable media are provided for facilitating patient health care by providing discovery, validation, and quality assurance of nomenclatural linkages between pairs of terms or combinations of terms in databases extant on multiple different health information systems that do not share a set of unified codesets, nomenclatures, or ontologies, or that may in part rely upon unstructured free-text narrative content instead of codes or standardized tags. Embodiments discover semantic structures existing naturally in documents and records, including relationships of synonymy and polysemy between terms arising from disparate processes, and maintained by different information systems. In some embodiments, this process is facilitated by applying Latent Semantic Analysis in concert with decision-tree induction and similarity metrics. In some embodiments, data is re-mined and regression testing is applied to new mappings against an existing mapping base, thereby permitting these embodiments to “learn” ontology mappings as clinical, operational, or financial patterns evolve.
