Abstract: A system and method is provided for capturing provenance from heterogeneous distributed communication systems. A point of coordination is monitored for messages that are input to and output from applications. Each message is identified and linked and each message is linked to the application that such message is input to or output from. Numerous sequences of such interactions can be linked together to form a provenance graph.

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.
