# Buckwalter Arabic Morphological Analyzer Version 1.0

### Introduction

This file contains documentation on the Buckwalter Arabic Morphological Analyzer Version 1.0, 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.

### Data

The data consists primarily of three Arabic-English lexicon files: prefixes (299 entries), suffixes (618 entries), and stems (82158 entries representing 38600 lemmas). The lexicons are supplemented by three morphological compatibility tables used for controlling prefix-stem combinations (1648 entries), stem-suffix combinations (1285 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. For more detailed information about the data, please see the original documentation file readme.txt.
