Learning the impact and behavior of syntactic structure: A case study in semantic textual similarity
We present a case study on the role of syntactic structures towards resolving the SemanticTextual Similarity (STS) task. Although various approaches have been proposed, the research of using syntactic information to determine the semantic similarityis a relatively under-researched area. At the level of syntactic structure, it is notclear how significant the syntactic structure contributes to the overall accuracy ofthe task. In this paper, we analyze the impact of syntactic structure towards theoverall performance and its behavior in different score ranges of the STS semantic scale.
