To support the development of data-driven approaches to natural language processing (NLP), human language technologies, automatic content extraction (topic extraction and/or grammar extraction), cross-lingual information retrieval, information detection, and other forms of linguistic research on Modern Standard Arabic in general, the LDC was sponsored to develop an Arabic Treebank of 1,000,000 words. This corpus is a re-release of part one of that project, with the addition in Version 3.0 of improved morphological/part-of-speech annotation (including full vocalization and case endings).
The project targets the description of a written Modern Standard Arabic corpus from the Agence France Presse (AFP) newswire archives for July-November 2000 (files dated 20000/7/15 to 2000/11/15). This corpus includes 734 stories representing 145,386 words (166,068 tokens after clitic segmentation in the Treebank; the number of Arabic tokens is 123,796). For this work, annotators must be native speakers of Arabic, and they must understand enough linguistics to check morphosyntactic analysis and build syntactic structures.
