Apologies for multiple postings] See you at Hilton Austin hotel on November 1st .. EMNLP 2016 Second Workshop on Computational Approaches to Linguistic Code Switching Hilton Austin hotel, Austin, Texas, USA November 1st, 2016 http://care4lang1.seas.gwu.edu/cs2/call.html Background
Code-switching (CS) is the phenomenon by which multilingual speakers switch back and forth between their common languages in written or spoken communication. CS is typically present on the inter sentential, intra sentential (mixing of words from multiple languages in the same utterance) and even morphological (mixing of morphemes) levels. CS presents serious challenges for language technologies, including parsing, Machine Translation (MT), automatic speech recognition (ASR), information retrieval (IR) and extraction (IE), and semantic processing. Traditional techniques trained for one language quickly break down when there is input mixed in from another. Even for problems that are considered solved, such as language identification, or part of speech tagging, performance will degrade at a rate proportional to the amount and level of mixed-language present. CS is pervasive in informal text communications such as news groups, tweets, blogs, and other social media of multilingual communities. Such genres are increasingly being studied as rich sources of social, commercial and political information. Apart from the informal genre challenge associated with such data within a single language processing scenario, the CS phenomenon adds another significant layer of complexity to the processing of the data. Efficiently and robustly processing CS data presents a new frontier for our NLP algorithms on all levels. This workshop aims to bring together researchers interested in solving the problem and to increase awareness of the community at large with possible viable solutions to reduce the complexity of the phenomenon. The workshop invites contributions from researchers working in NLP approaches for the analysis and/processing of mixed-language data especially with a focus on intra sentential code switching. Invited Speakers *Monojit Choudhury* <http://research.microsoft.com/en-us/people/monojitc/> *Bio:* Monojit Choudhury is a Researcher at Microsoft Research Lab India. Prior to this, he did his PhD (2007) and B.Tech (2002), both in Computer Science and Engineering, from Indian Institute of Technology Kharagpur. His research interests include NLP for low resource languages, technologies for multilingual communities, and computational approaches to linguistics, sociolinguistics, evolutionary linguistics and cognition. Monojit is very actively involved with the organization of the International Linguistics Olympiad http://www.ioling.org and its Indian national counterpart – the Panini Linguistics Olympiad http://plo-in.org – programs that try to attract the brightest high school kids to linguistics and NLP through challenging yet interesting and thought-provoking puzzles. *Kalika Bali <http://research.microsoft.com/en-us/people/kalikab/>* *Bio:* Kalika Bali is a Researcher at Microsoft Research Lab India. A linguist and an acoustic phonetician by training, she has worked for the last 15 years in the area of Speech and Language Technology, especially for resource poor languages. Her brief stint as a lecturer in the University of the South Pacific, Fiji, has left her with a lasting interest in how technology can be used to enhance and further education and some of her current research lies at the intersection of ICT and Education, for primary school students to Adults learning new skills. The primary focus of her research is on how Natural Language systems can help Human-Computer Interaction, including computer-mediated interaction, in the domain of education and social media.
