Investigating the Correctness of Attributing the MunajatKhams 'Ashar to Imam Sajjad (PBUH) Based on Stylometry Techniques

Advances in science and technology have made it no longer acceptable to have works with a dubious author. Stylometry is a method that uses statistical analysis to determine the author of a literary work. Author attribution methods rely heavily on writing style; assuming that each person has unique style. Author identification is used in areas such as plagiarism, criminology, and unspecified author identification. Due to the fact that many factors are involved in identifying the author of texts, a method with 100% accuracy has not been presented so far, and researchers are still trying to find a way to minimize computational errors. One of the methods that is claimed to have good accuracy is Yule’s theory. In this article, Yule's theory and four other theories have been combined to compare the vocabulary richness of the Munajat Khams 'Ashar and the prays of Al-Sahifa al-Sajjadiyya. Then, Using descriptive-analytical method and explanation of statistical datas, the correctness of the attribution of Munajat Khams 'Ashar to Imam Sajjad (PBUH) has been investigated. The results show the high accuracy of the calculations and the independence of the output of the theories to the length of the text. Also, due to the slight difference between the vocabulary richness of the Munajat Khams 'Ashar and the prays of Al-Sahifa al-Sajjadiyya, its attribution to Imam Sajjad (PBUH) is confirmed.
