One of the areas of applications of Stylometry is authorship attribution to articles of ambiguous authorship. The present paper deals with the classification of articles of unknown authorship to the articles written by contemporary Tamil scholars of the same period, namely Mahakavi Bharathiar (MB), Subramniya Iyer (SI), and T. V. Kalyanasundaranar (TVK). These three popular scholars had written number of articles on India's Freedom Movement during the pre-independence period and published in the magazine called, India. Initially, all the three writers contributed their articles by attributing their names. The oppressive attitude of the then British regime compelled all the three patriots to write articles on the same theme for anonymous publications without mentioning their names. Later, all the three patriots wrote the articles on the same subject for unidentified publications without their names due to the oppressive attitude of the then British rule. In this paper, the assignment of articles of ambiguous authorship to contemporary writers, namely, Mahakavi Bharathiar (MB), Subramaniya Iyer (SI), and T. V. Kalyanasundaranam (TVK), using the applications of Principal Component Analysis (PCA) and Multivariate Discriminant Analysis (MDA) is discussed. Different sets of stylistic parameters of the above mentioned three Tamil scholars are considered in the analysis and the writing styles of these authors are quantified, using morphological and function words. Almost the entire set of articles of ambiguous authorship is attributed to Mahakavi Bharathiar.
