Non-binary Evaluation for Schema Matching

In this work we extend the commonly used binary evaluation of schema matching to support evaluation methods for non-binary matching results as well. We motivate our work with some new applications of schema matching. Non-binary evaluation is formally defined together with a set of three new, non-binary evaluation measures using a vector-space representation of schema matching outcome. We provide an empirical evaluation to support the usefulness of non-binary evaluation and show its superiority to its binary counterpart.
