Tools and methods for semi-automatic schema matching
First Claim
1. A schema matching tool for establishing correspondences between data elements on disparate schemata, comprising:
- means for inputting at least one source schema and at least one target schema;
means for generating a set of match scores representing potential correspondences between elements in the source schemata and elements in the target schemata;
means for combining the set of match scores to yield a confidence value for each of the potential correspondences; and
means for displaying each confidence value.

Abstract
Tools and methods for schema matching that generate schema graphs, populate match matrices and display the schema graphs and the match matrices. These tools and methods characterize potential matches between disparate schemata in terms of both a strength of evidence indicating the potential match and an amount of evidence indicating the potential match. A number of match voters generate a set of match scores for each potential match, and these match scores are combined by a vote merger to form a single confidence value for each potential match. A number of filters display the confidence value for each potential match as a link on a graphical user interface. Machine-learning techniques may be employed to adaptively determine confidence values based on previously established matches.
