Discovery of Service HyperLinks with User Feedbacks for Situational Data Mashup

Discovery of loose data linkages between data services can help on-demand Web data integration in accordance with situation changes. However, we met the uncertainty challenge when discovering such data linkages with current automatic matchers. To handle the uncertainty problem, this paper develops a synthesized matching algorithm to combine the matching results from multiple automatic matchers with user feedbacks. It also proposes a service hyperlink model to encapsulate such data linkages for further reuse. Experiments show our approach can effectively improve the correctness of discovered data linkages.
