Abstract

The present invention relates to a computer-implemented method and system for semi-automated schema matching in a data processing environment. Schema data from at least one data source is received and normalised into a domain-level abstraction using a predefined transformation rule. At least one schema matching algorithm analyses syntactic and semantic similarities between schema elements to generate candidate correspondences. A confidence score is computed for each correspondence using a machine learning-based confidence model or a fuzzy Boolean-based confidence model, and a subset of correspondences are presented to a user via an interactive interface for validation. The schema matching model is iteratively updated by propagating semantic context from at least one user-confirmed mapping, refining the model to improve future schema matching predictions. Semantic context derived from user-confirmed mapping is used to identify unmapped schema elements that share a base type with confirmed elements, adjusting confidence scores for those unmapped elements. Validated schema mappings are stored in a repository for later retrieval and use. The system further supports re-evaluating schema correspondence based on updated schema structures, ensuring schema mappings remain consistent as schemas evolve.
