: [Arabic, Morphology, Finite State] This paper describes a finite-state morphological analyzer of written Modern Standard Arabic words that is available for testing on the Internet at http://www.xrce.xerox.com/research/mltt/arabic. The system consists of the analyzer proper, running on a network server, and Java applets that run on the user's machine and render words in standard Arabic orthography both for input and output. An overview of the system is provided, including the history, finite-state technology, dictionary coverage and status. 1 Introduction In 1996, the Xerox Research Centre Europe produced a large morphological analyzer for Modern Standard Arabic, henceforth Arabic (Beesley, 1996). In 1997, the rules were rewritten to more reliably support generation, and a Java user interface was added to allow users to interact with the system via the Internet in standard Arabic orthography. The analyzer-generator is based on dictionaries from an earlier project at ALPNET (Beesley,...
