The properties of property alignment

Abstract

Abstract. The performance of alignment systems on property matching lags significantly behind that on class and instance matching. This work seeks to understand the reasons for this and consider possible avenues for improvement. The paper contains an in-depth exploration of the per-formance of current alignment systems on the only commonly accepted alignment benchmark that involves matches between properties. A sec-ond benchmark involving properties is also proposed. Finally, an entirely string-based approach targeted towards aligning properties is presented and evaluated using both benchmarks. 1
