Authorship attribution is the process of assigning an author to an anonymous text based on writing characteristics. Several authorship attribution methods were developed for natural languages, such as English, Chinese and Dutch. However, the number of related works for Arabic is limited. Naïve Bayes classifiers have been widely used for various natural language processing tasks. However, there is generally no mention of the event model used, which can have a considerable impact on the performance of the classifier. To the best of our knowledge, naïve Bayes classifiers have not yet been considered for authorship attribution in Arabic. Therefore, we propose to study their use for this problem, taking into account different event models, namely, simple naïve Bayes (NB), multinomial naïve Bayes (MNB), multi-variant Bernoulli naïve Bayes (MBNB) and multi-variant Poisson naïve Bayes (MPNB). We evaluate these models' performances on a large Arabic dataset extracted from books of 10 different authors and compare them with other existing methods. The experimental results show that MBNB provides the best results and could attribute the author of a text with an accuracy of 97.43%. Comparison results with related methods indicate that MBNB and MNB are appropriate for authorship attribution.
