Semantic lexical matching is a prominent subtask within text understanding applica- tions. Yet, it is rarely evaluated in a di- rect manner. This paper proposes a def- inition for lexical reference which cap- tures the common goals of lexical match- ing. Based on this definition we created and analyzed a test dataset that was uti- lized to directly evaluate, compare and im- prove lexical matching models. We sug- gest that such decomposition of the global semantic matching task is critical in order to fully understand and improve individual components.
