ACL-02 Workshop on Speech-to-Speech Translation: Algorithms and Systems July 11 2002 University of Pennsylvania, Philadelphia A workshop held as part of the Association for Computational Linguistics 40th anniversary meeting ACL-02 (http://www.acl02.org) Hosted by The Computer and Information Science Department and the Institute for Research in Cognitive Science University of Pennsylvania, Philadelphia July 7-12 2002 CALL FOR PAPERS DESCRIPTION: Facilitation of speech communication across language barriers is a critical problem to solve for a global economy to thrive. Robust systems for speech-to-speech translation (S2S) are clearly necessary to move us towards achieving this goal. However, construction of such systems is clearly extremely complex, involving research in Automatic Speech Recognition(ASR), Text-to-Speech (TTS), Machine Translation (MT), Natural Language Understanding (NLU) and Generation (NLG). Although substantial progress in each of these components individually has been made over the last two decades, simply integrating individual ASR, NLU, MT, NLG, and TTS components to produce S2S systems is not sufficient to produce acceptable results. For example, conventional text-based MT systems have not been designed to cope with the imperfect syntax and transcription errors which characterize automatically transcribed conversational speech. Traditional speech recognizers (ASR component) and speech synthesizers (TTS component) have not been designed to recognize or synthesize speakers' emotional expressions which convey meanings and play an important role in the communications between human beings. Therefore, speech-to-speech translation raises a whole new set of algorithmic challenges over and above those associated with the individual underlying technologies themselves. We would like to bring together various researchers in the field together to present the current state-of-the-art on speech-to-speech translation and discuss the challenges involved in building a functioning high performance system. We hope to hear about different approaches to the S2S realization and exchange ideas about the advantages and disadvantages of various approaches. The workshop will specifically focus on natural language processing problems which are unique and critical to producing robust speech-to-speech translation systems and components. We solicit submissions to the workshop in the following areas, however any other topic related to the speech-to-speech translation is also acceptable: Machine Translation: - Algorithms for machine translation applicable to S2S - Algorithms and systems for application specific and limited domain machine translation - Rule-based MT, statistical MT, template-based MT, interlingua-b ased MT Speech recognition and TTS: - Enhancing the performance of ASR in S2S using natural language processing techniques - TTS modules with highly naturalness and emotional expressions - Robust speech recognition algorithms for S2S - Challenges for extracting and conveying stress, prosody and emo tions in speech across languages NLP: - Natural language processing algorithms for S2S - Natural language generation from meaning representations Language: - Challenges for speech-to-speech translation across languages du e to language characteristics, and suggestion of solutions - Challenges for conveying stress, prosody and emotions in speech across languages System architecture and software integration - Component architecture and design of modular S2S systems - Portability of S2S systems to different languages and domains - Implementation issues for robust and limited resource S2S systems Multilingual Data Collection and System Evaluation: - Evaluation metrics of spoken language translation quality - Language resources and knowledge acquisition SUBMISSIONS: We invite paper submissions from all researchers in the area of S2S translation, natural language processing, linguistics, and all related topics. All submissions will be reviewed by an international program committee. If sufficiently many high-quality papers are submitted, we will consider publishing selected papers in an edited volume. Submissions should follow the two-column format of ACL proceedings and should not exceed eight (8) pages, including references. We recommend the use of ACL LaTeX style files or Microsoft Word Style files available at: http://www.cs.ualberta.ca/~lindek/acl02/style/. Deadline for paper submissions is March 15, 2002.

EFFECTIVE TOOLS AND METHODOLOGIES FOR TEACHING NLP AND CL An ACL 2002 Workshop July 7, 2002 (the day before the main conference) Philadelphia, PA, USA http://www.eecs.umich.edu/~radev/TeachingNLP Co-chairs: Chris Brew, Ohio State University Dragomir Radev, University of Michigan INTRODUCTION Natural Language Processing (and Computational Linguistics) courses have been enjoying a large interest in the last few years. More and more universities are offering both introductory and advanced classes. Over the years, faculty from different departments have been developing their classes by introducing and refining new lectures, software, and projects. Some of the main challenges in teaching NLP are: 1. Teaching to a diverse audience, consisting of a mix of students in Linguistics, Computer Science, Information Science, and Bioinformatics; both undergraduate and graduate; and with a wide range of proficiency in linguistics, computer theory, or programming. 2. Selecting an appropriate focus for a course, e.g., theory vs. applications, symbolic vs. empirical, text-only vs. text+speech, etc. 3. Finding an appropriate place of an NLP/CL course within a larger curriculum, e.g., in Artificial Intelligence, Computational Linguistics, Cognitive Science, or Language Engineering. 4. Finding the right links to related areas, such as Theoretical Linguistics, Information Retrieval, Speech Science, Cognitive Science, Artificial Intelligence, or Genetic/Molecular Biology. 5. Choosing appropriate assignments to provide the right mix of theoretical, programming and data analysis exercises. 6. Designing software for educational purposes and developing tutorials on existing software. This ACL workshop on Effective Tools and Methodologies for Teaching NLP/CL will address these challenges. The workshop will bring together college faculty with experience in teaching such courses as well as future teachers (e.g., current graduate students). CALL FOR PAPERS We will be soliciting short papers (4-6 pages) on the following topics: 1. Effective course lectures 2. Innovative assignments and projects 3. Educational software 4. Web resources 5. Curriculum issues (e.g., developing an effective multi-course CL program) 6. Teaching NLP in different departments: Computer Science, Linguistics, Information Science, etc. 7. Connecting teaching and research 8. Seminar-style courses 9. Choice of programming languages (and programming requirements in general) 10. Teaching NLP in languages other than English 11. Evaluation issues (outcomes assessment, educational measurement, etc.) In addition to these papers, the organizers will be collecting pointers to educational resources on the Web, including course notes, assignments, tutorials, software, and demos. The workshop will feature a panel discussing longer-term activities such as a mailing list for instructors, an archive of educational materials, etc. Submissions should be formatted according to the ACL style guide (http://www.cs.ualberta.ca/~lindek/acl02/style) and must be in either PS, PDF, or DOC format. These should be sent electronically to radevMail to author|Respond to list|Read more issues|LINGUIST home page|Top of issueumich.edu by the deadline shown below. Hard copies will be accepted only if the authors explicitly make such arrangements the co-chairs at least one week prior to the official submission date. In that case, the hard copies will still have to arrive by the submission date. We will assemble printed proceedings, however the ultimate goal of this workshop would be laying the groundwork for further professional collaboration in teaching NLP/CL, creating an ACL SIG, and building a clearinghouse for educational materials. IMPORTANT DATES Papers due: March 29, 2002 Acceptance or rejection notification: April 22, 2002 Camera-ready versions due: May 17, 2002 Workshop: July 07, 2002 REGISTRATION Registration fees are $50 for regular participants and $0 (free) for up to 10 lower income participants (e.g., graduate students and/or participants from Eastern Europe, Africa, and other disadvantaged areas of the world). Candidates for registration fee waivers should indicate their interest to the program co-chairs by April 22. Authors of accepted papers will have priority, then authors of rejected papers, then all others. PROGRAM COMMITTEE Chris Brew (co-chair), Ohio State University, cbrew
