SIGARAB Mission

Arabic Natural Language Processing (Arabic NLP) is challenging:  Arabic has a complex and rich morphology, a high degree of ambiguity, as well as many dialects that vary quite widely. Arabic is one of the six official languages of the United Nations, the national language of over 400 million people from 23 states, and the liturgical language of 1.8 billion Muslims around the world.  The opportunities that are made possible by working on Arabic NLP cannot be underestimated in their consequence on the Arab world, the Mediterranean region, and the rest of the world.

SIGARAB is the Special Interest Group of the Association for Computational Linguistics for researchers concerned with all aspects of Arabic NLP. 

The activities of SIGARAB include: 

• Exchange and propagation of research results, publications and resources relevant to all subareas of Arabic NLP, and for all Arabic variants (Standard, Classical and Dialectal).

• Coordination between organizations in academia and industry throughout the world performing research in Arabic NLP or using Arabic NLP.

• Sponsoring a number of Arabic NLP events 

  • The Arabic NLP Winter School 2025 (co-located with COLING 2025)

  • The Arabic Natural Language Processing Conference (ArabicNLP)

    • Previously The Arabic Natural Language Processing Workshop (WANLP)

(SIGARAB)

I. Statement of Purpose

Arabic Natural Language Processing (Arabic NLP) is challenging:  Arabic has a complex and rich morphology, a high degree of ambiguity, as well as many dialects that vary quite widely. Arabic is one of the six official languages of the United Nations, the national language of over 400 million people from 23 states, and the liturgical language of 1.8 billion Muslims around the world.  The opportunities that are made possible by working on Arabic NLP cannot be underestimated in their consequence on the Arab world, the Mediterranean region, and the rest of the world.

• To promote coordination between organizations in academia and industry throughout the world performing research in Arabic NLP or using Arabic NLP;

• To provide ACL members with interest in Arabic NLP with a means of exchanging news of recent research developments and other matters of interest in Arabic NLP;

• To sponsor regular, timely and worthwhile meetings and workshops on Arabic NLP.

SIGARAB will operate within the framework of the ACL's general guidelines for SIGs.
