    This corpus was produced within the NEMLAR project (http://www.nemlar.org). Two other resources, produced within the same project, are also available: NEMLAR Broadcast News Speech Corpus (ELRA-S0219) and the NEMLAR Speech Synthesis Corpus (ELRA-S0220).

    The NEMLAR Written Corpus consists of about 500,000 words of Arabic text from 13 different categories, aiming to achieve a well-balanced corpus that offers a representation of the variety in syntactic, semantic and pragmatic features of modern Arabic language. The different categories are:
    • Political news: 48,000 words
    • Political debate: 30,000 words
    • Islamic text (Preaching and others): 29,000 words
    • Phrases of common words: 8,500 words
    • Text from broadcast news: 5,500 words
    • Business: 20,000 words
    • Arabic literature: 30,000 words
    • General news: 100,000 words
    • Interviews: 56,000 words
    • Scientific press: 50,000 words
    • Sports press: 50,000 words
    • Dictionary entries explanation: 52,000 words
    • Legal domain text: 21,000 words

    The time span of the data included goes from late 1990’s to 2005.

    The corpus is provided in 4 different versions:
    • Raw text
    • Fully vowelized text
    • Text with Arabic lexical analysis
    • Text with Arabic POS-tags

    Diacritics, lexical analysis and POS-tags were generated by RDI’s tool Fassieh©. The accuracy of the automatic analysis is around 95%. To reach about the 99% accuracy rate as defined for this corpus, the linguists used the visual revision mode of Fassieh© where the linguist has to either approve the 1st most likely analysis (most of the time) or select another one manually (in the 4% minority of the cases).

    The database is distributed on 1 ISO 9660 CD-ROM volume. It has been validated by an external partner and a validation report is provided.
