public final class Glosser_ar_en
extends AbstractAnalyzer

An english glosser for the arabic language. This glosser uses Tim Buckwalter's algorithm (available at LDC Catalog) to identify the morphological category of arabic tokens and then return their glosses. The meaningful morphological categories are still to be determined but the current list gives good results.
