Ghostwriter Verification of Yasunari Kawabata’s Novel Hananikki

Abstract

　It has long been argued that Yasunari Kawabata uses ghostwriters. Hananikki, one of his girls’ novel was suspected to be written by his discipline Tsuneko Nagazato. In this paper, we provide acomputational stylistics based solution for the ghostwriter suspicion of Hananikki. Character and symbol bigrams，part of speech (POS) tag bigrams and phrase patterns are used as stylometric features.Adaptive boosting (AdaBoost)，High-Dimensional discriminant analysis (HDDA)，Logistic model tree(LMT)，Support vector machine (SVM) and Random forest (RF) are used as classifiers. The result reveals that Hananikki is collaboratively written by Yasunari Kawabata and Tsuneko Nakazato.
