Title CATS: A Tool for Customized Alignment of Text Simplification Corpora
Authors Sanja Štajner, Marc Franco-Salvador, Paolo Rosso and Simone Paolo Ponzetto
Abstract In text simplification (TS), parallel corpora consisting of original sentences and their manually simplified counterparts are very scarce and small in size, which impedes building supervised automated TS systems with sufficient coverage. Furthermore, the existing corpora usually do not distinguish sentence pairs which present full matches (both sentences contain the same information), and those that present only partial matches (the two sentences share the meaning only partially), thus not allowing for building customized automated TS systems which would separately model different simplification transformations. In this paper, we present our freely available, language-independent tool for sentence alignment from parallel/comparable TS resources (document-aligned resources), which additionally offers the possibility for filtering sentences depending on the level of their semantic overlap. We perform in-depth human evaluation of the tool's performance on English and Spanish corpora, and explore its capacities for classification of sentence pairs according to the simplification operation they model.
