Abstract
Using a pay-as-you-go strategy, we allow for a community of users to validate mappings obtained by an automatic ontology matching system using consensus for each mapping. The ultimate objectives are effectiveness—improving the quality of the obtained alignment (set of mappings) measured in terms of F-measure as a function of the number of user interactions—and robustness—making the system as much as possible impervious to user validation errors. Our strategy consisting of two major steps: candidate mapping selection, which ranks mappings based on their perceived quality, so as to present first to the users those mappings with lowest quality, and feedback propagation, which seeks to validate or invalidate those mappings that are perceived to be “similar ” to the mappings already presented to the users. The purpose of these two strategies is twofold: achieve greater improvements earlier and minimize overall user interaction. There are three important features of our approach. The first is that we use a dynamic ranking mechanism to adapt to the new conditions after each user interaction, the second is that we may need to present each mapping for validation more than once—revalidation—because of possible user errors, and the third is that we propagate a user’s input on a mapping immediately without first achieving consensus for that mapping. We study extensively the effectiveness and robustness of our approach as several of these parameters change, namely the error and revalidation rates, as a function of the number of iterations, to provide conclusive guidelines for the design and implementation of multi-user feedback ontology matching systems. 1.
