There are a total of 144,199 words (counting non-Arabic tokens such as numbers and punctuation) in the 501 files - one story per file. New features of annotation include complete vocalization (including case endings), lemma IDs, and more specific POS tags for verbs and particles.</p><br>
<p>The corpus contains 125,698 Arabic-only word tokens (prior to the separation of clitics), of which 124,740 (99.24%) were provided with an acceptable morphological analysis and POS tag by the morphological parser, and 958 (0.76%) were items that the morphological parser failed to analyze correctly.</p><br>
