Claim Text:
1. A computer-implemented method of providing a user-guided multi-schema integration, the method being executed using one or more processors and comprising: receiving a plurality of schemas from computer-readable memory, each schema of the plurality of schemas defining a data structure and comprising a plurality of intermediate elements and a plurality of leaf elements; receiving leaf correspondences from a computer-readable memory, the leaf correspondences matching leaf elements between schemas of the plurality of schemas and being associated with a maximum of a confidence level, processing the plurality of schemas and the leaf correspondences using closed frequent itemset mining (CFIM) to determine intermediate correspondences, the intermediate correspondences matching intermediate elements between schemas of the plurality of schemas and being associated to the confidence level that depends on a position of the intermediate elements in each schema of the plurality of schemas and to define a first plurality of redundancy groups, each redundancy group in the first plurality of redundancy groups comprising a proposed correspondence between intermediate elements of schemas of the plurality of schemas; displaying, using a display device, the first plurality of redundancy groups to a user; receiving user input, the user input comprising one or more actions to one or more redundancy groups in the first plurality of redundancy groups; processing the plurality of schemas and the leaf correspondences to hide at least one of the plurality of schemas based on the one or more actions to define a second plurality of redundancy groups; and displaying, using a display device, the second plurality of redundancy groups to the user.
