In the context of Information Retrieval, Arabic stemming algorithms have become a most research area of
information retrieval. Many researchers have developed algorithms to solve the problem of stemming.
Each researcher proposed his own methodology and measurements to test the performance and compute
the accuracy of his algorithm. Thus, nobody can make accurate comparisons between these algorithms.
Many generic conflation techniques and stemming algorithms are theoretically analyzed in this paper.
Then, the main Arabic language characteristics that are necessary to be mentioned before discussing
Arabic stemmers are summarized. The evaluation of the algorithms in this paper shows that Arabic
stemming algorithm is still one of the most information retrieval challenges. This paper aims to compare
the most of the commonly used light stemmers in terms of affixes lists, algorithms, main ideas, and
information retrieval performance. The results show that the light10 stemmer outperformed the other
stemmers. Finally, recommendations for future research regarding the development of a standard Arabic
stemmer were presented.
