Motivation and Aims

 

This Workshop intends to add value to the issues addressed during the main conference (Human Language Technologies (HLT) & Natural Language Processing (NLP)) and enhance the work carried out at different places to process Arabic language(s) and more generally Semitic languages and other local and foreign languages spoken in the region.

 

It should bring together people who are actively involved in Arabic Written and Spoken language processing in a mono- or cross/multilingual context, and give them an opportunity to update the community through reports on completed and ongoing work as well as on the availability of LRs, evaluation protocols and campaigns, products and core technologies (in particular open source ones). This should enable the participants to develop a common view on where we stand with respect to these particular set of languages and to foster the discussion of the future of this research area.  Particular attention will be paid to activities involving technologies such as Machine Translation, Cross-Lingual Information Retrieval/extraction, Summarization, Speech to text transcriptions, etc., and languages such as Arabic varieties, Amazigh, Amharic, Hebrew, Maltese, and other local languages. Evaluation methodologies and resources for evaluation of HLT are also a main focus.

 

It is clear from the various projects that Arabic has become a major language for HLT. During this workshop we will emphasize the need to focus on specific issues that would help citizens living in Arabic countries to have access to information and technologies in their mother tongues and therefore discuss requirements to customize existing technologies for pairs of languages e.g. English to Arabic, Amazigh, etc. A particular stress will be put on tools, technologies, resources that tackle colloquial Arabic and other local languages such as Amazigh.

 

We expect to identify problems of common interest, and possible mechanisms to move towards solutions, such as sharing of resources, tools, standards, sharing and dissemination of information and expertise, adoption of current best practices, setting up joint projects and technology transfer mechanisms, etc.

 

By bringing together players in the Arabic NLP field, we would like to follow activities discussed at similar workshops (e.g. LREC2002) but also at the NEMLAR conference on Arabic Language (2004, Cairo Egypt), the workshop on Arabic NLP (Fez, April, 2007, http://www.dsic.upv.es/~prosso/workshopAECI_ArabicNLP.pdf) as well as work carried out in projects such as NET-DC, NEMLAR (www.nemlar.org) or the LDC project on the "Less Commonly Taught Languages".  The objective is also to introduce activities that will be launched shortly within the MEDAR project (the follow-up of NEMLAR project under FP7 of the European Commission). Among the crucial issues that require particular attention is the construction/update of a broadly supported Roadmap for these languages in relationship with Multilinguality and Evaluation of HLTs.

 

Topics of Interest

 

The submissions should address some of the LREC issues that are specific and of paramount importance to the Arabic resources and evaluation; some of these issues are:

 

·        Issues in the design, the acquisition, creation, management, access, distribution, use of Language Resources (Standard Arabic, Colloquial Arabic, other Semitic languages, Amazigh, Coptic, Maltese, English/French spoken locally, etc.)

·        Impact on LR collections/processing and NLP of the crucial issues related to "code switching" between different dialects and languages

·        Specific issues related to the above-mentioned languages such as role of morphology, named entities, corpus alignment, etc.)

·        Multilinguality issues including relationship between Colloquial and Standard Arabic

·        Exploitation of LR in different types of applications 

·        Industrial LR requirements and community's response;

·        Benchmarking of systems and products; resources for benchmarking and evaluation for written and spoken language processing;

·        Focus on some key technologies such as MT (all approaches e.g. Statistical, Example-Based, etc.), Information Retrieval, Speech Recognition, Spoken Documents Retrieval, CLIR, Question-Answering, Summarization,

·        Local, regional, and international activities and projects;

·        Needs, possibilities, forms, initiatives of/for regional and international cooperation.

 

Format of the Workshop

 

It will be a full-day workshop. The workshop is not intended to be a mini-conference, but as a real workshop aiming at concrete results that should clarify the situation of Arabic with respect to Language Resources and Evaluation. Sessions will include introductory speeches, invited talks, a small number of refereed presentations, etc.
