Build Fast and Accurate Lemmatization for Arabic
In this paper we describe the complexity of building a lemmatizer for Arabic which has a rich and complex morphology, and show some differences between lemmatization and surface stemming, i.e. removing prefixes and suffixes from words. We discuss the need for a fast and accurate lammatization to enhance Arabic Information Retrieval results. We also introduce a new dataset that can be used to test lemmatization accuracy, and an efficient lemmatization algorithm that outperforms state-of-the-art Arabic lemmatization in terms of accuracy and speed. We share the dataset and the code for research purposes.
