   abstract = "In this thesis, we attempt to use a machine-learning algorithm,
                PNrule, along with simple lexical and syntactic measures to detect
                paraphrases in cases where their existence is rare. We choose PNrule
                because it was specifically developed for classification in instances
                where the target class is rare compared to other classes within the
                data. We test our system both on a dataset we develop based on movie
                reviews, and on the PASCAL RTE dataset; we obtain poor results on the
                former, and moderately good results on the latter. We examine why
                this is the case, and suggest improvements for future research.",
