Full Title: ELRA Workshop on Evaluation Date: 27-May-2008 - 27-May-2008 Location: Marrakech, Morocco Contact Person: Victoria Arranz Meeting Email: arranz elda.org Web Site: http://www.lrec-conf.org/lrec2008/Workshops.html Linguistic Field(s): Computational Linguistics Call Deadline: 28-Jan-2008 Meeting Description ELRA Workshop on Evaluation Looking into the Future of Evaluation: when automatic metrics meet task-based and performance-based approaches To be held in conjunction with the 6th International Language Resources and Evaluation Conference (LREC 2008) 27 May 2008, Palais des Congrès Mansour Eddahbi, Marrakech Background Automatic methods to evaluate system performance play an important role in the development of a language technology system. They speed up research and development by allowing fast feedback, and the idea is also to make results comparable while aiming to match human evaluation in terms of output evaluation. However, after several years of study and exploitation of such metrics we still face problems like the following ones: - they only evaluate part of what should be evaluated - they produce measurements that are hard to understand/explain, and/or hard to relate to the concept of quality - they fail to match human evaluation - they require resources that are expensive to create etc. Therefore, an effort to integrate knowledge from a multitude of evaluation activities and methodologies should help us solve some of these immediate problems and avoid creating new metrics that reproduce such problems. Looking at MT as a sample case, problems to be immediately pointed out are twofold: reference translations and distance measurement. The former are difficult and expensive to produce, they do not cover the usually wide spectrum of translation possibilities and what is even more discouraging, worse results are obtained when reference translations are of higher quality (more spontaneous and natural, and thus, sometimes more lexically and syntactically distant from the source text). Regarding the latter, the measurement of the distance between the source text and the output text is carried out by means of automatic metrics that do not match human intuition as well as claimed. Furthermore, different metrics perform differently, which has already led researchers to study metric/approach combinations which integrate automatic methods into a deeper linguistically oriented evaluation. Hopefully, this should help soften the unfair treatment received by some rule-based systems, clearly punished by certain system-approach sensitive metrics. On the other hand, there is the key issue of ''what needs to be measured'', so as to draw the conclusion that ''something is of good quality'', or probably rather ''something is useful for a particular purpose''. In this regard, works like those done within the FEMTI framework have shown that aspects such as usability, reliability, efficiency, portability, etc. should also be considered. However, the measuring of such quality characteristics cannot always be automated, and there may be many other aspects that could be usefully measured. This workshop follows the evolution of a series of workshops where methodological problems, not only for MT but for evaluation in general, have been approached. Along the lines of these discussions and aiming to go one step further, the current workshop, while taking into account the advantages of automatic methods and the shortcomings of current methods, should focus on task-based and performance-based approaches for evaluation of natural language applications, with key questions such as: - How can it be determined how useful a given system is for a given task? - How can focusing on such issues and combining these approaches with our already acquired experience on automatic evaluation help us develop new metrics and methodologies which do not feature the shortcomings of current automatic metrics? - Should we work on hybrid methodologies of automatic and human evaluation for certain technologies and not for others? - Can we already envisage the integration of these approaches? - Can we already plan for some immediate collaborations/experiments? - What would it mean for the FEMTI framework to be extended to other HLT applications, such as summarization, IE, or QA? Which new aspects would it need to cover? We solicit papers that address these questions and other related issues relevant to the workshop. Workshop Programme and Audience Addressed This full-day workshop is intended for researchers and developers on different evaluation technologies, with experience on the various issues concerned in the call, and interested in defining a methodology to move forward. The workshop feature invited talks, submitted papers, and will conclude with a discussion on future developments and collaboration.

Full Title: Proyecto de la Diáspora Latinoamericana Short Title: ALFAL Date: 18-Aug-2008 - 21-Aug-2008 Location: Montevideo, Montevideo, Uruguay Contact Person: Rocio Raña Risso Meeting Email: diasporalatina nyc.rr.com Web Site: http://www.mundoalfal.org Linguistic Field(s): General Linguistics; Language Acquisition; Psycholinguistics; Sociolinguistics Subject Language(s): Portuguese (por) Spanish (spa) Call Deadline: 31-Jan-2008 Meeting Description The Research Group on Linguistic Issues Involving the Latin American Dispora is a 'Proyecto de Investigación' meeting with the XV International Conference of the Latin American Association of Linguistics and Philology (ALFAL) in Montevideo, Uruguay from August 18 to 21. Second Call for Papers Abstracts of between 200 and 250 words are invited for 20 minute presentations on linguistic research in sociolinguistics, psycholinguistics, or applied linguistics (or combination) involving the Latin American Diaspora, defined as peoples of Latin American heritage living outside their country of origin (e.g., in North America, Europe, or other Latin American countries). Such communities are of interest because of the situations of dialect and language contact they entail and the social, educational, and linguistic issues involved in their adaptation to new matrix societies. The abstract must be written in Spanish or Portuguese, the official languages of the conference. Presentations at the conference must also be delivered in Spanish or Portuguese. There is also the possibility of publishing a paper in either of these languages in the conference proceedings. To submit your abstract: send an e-mail to diasporalatina nyc.rr.com with your name, affiliation, and the abstract in the body of the e-mail and as an attachment. Please see the conference website for more information: http://www.mundoalfal.org New Extended Deadline: 31-Jan-2008 Notice of acceptance: 15/03/08 Coordinators Michael Newman Associate Professor of Linguistics michael.newman qc.cuny.edu, 718-997-2871 Department of Linguistics and Communication Disorders Queens College, CUNY; Flushing, NY 11367 Eva M.
