IntroductionBuckwalter Arabic Morphological Analyzer Version 1.0 was produced by Linguistic Data Consortium (LDC), catalog number LDC2002L49 and ISBN 1-58563-257-0. The Buckwalter Arabic Morphological Analyzer is used for POS-tagging Arabic text. DataThe data consists primarily of three Arabic-English lexicon files: prefixes (299 entries), suffixes (618 entries), and stems (82,158 entries representing 38,600 lemmas). The lexicons are supplemented by three morphological compatibility tables used for controlling prefix-stem combinations (1,648 entries), stem-suffix combinations (1,285 entries), and prefix-suffix combinations (598 entries). The actual code for morphology analysis and POS tagging is contained in a Perl script. The documentation consists of a readme file with a description of the lexicon files, the morphological compatibility tables, the morphology analysis algorithm, a summary of stem morphological categories, and a table with the author's Arabic transliteration system. UpdatesThere has been a case mismatch in the manner by which six files were named in the data, compared with their names in the documentation and the script, which caused the analyzer to crash on case sensitive systems. This problem has been remedied and you can now download the fixed version of the analyzer.Content CopyrightPortions © 2002 QAMUS LLC (www.qamus.org), © 2002 Trustees of the University of Pennsylvania The Linguistic Data Consortium is releasing this software under
