The volume of Arabic posts on many social networks has increased significantly, providing a rich source for analysis. As a result, Arabic Natural Language Processing intervenes to exploit this source and extract invisible but valuable insights. This paper presents a review of recent studies on techniques used in the Arabic Natural Language Processing field to come up with the faced challenges and the new trends. The articles selected for the review are primarily studies on Arabic Natural Language Processing techniques, as we collected and analysed a set of journal papers published in this field between 2018 and 2022. Based on the analysis, we extracted the various ANLP steps and investigated the techniques used in each step. The article also outlines the current trends in the several phases and steps of the Arabic Natural Language Processing process. As a result, it gives an insight into the current state of research.
