The lexicons are supplemented by three morphological compatibility tables used for controlling prefix-stem combinations (2,435 entries), stem-suffix combinations (1,612 entries), and prefix-suffix combinations (1,138 entries). The actual code for morphology analysis and POS tagging is contained in a Perl script (AraMorph.pl). Sample input (infile.txt) and corresponding output file (outfile.xml) are provided. The documentation consists of a readme file with a description of the three lexicon files, the three morphological compatibility tables, the morphology analysis algorithm, and a table with the authors Arabic transliteration system.
