cs.rutgers.edu>________________________________________________________________ WordNet and Other Lexical Resources: Applications, Extensions and Customizations * Please note merger and extended deadline! * NAACL 2001 Workshop Carnegie Mellon University, Pittsburgh 3 and 4 June, 2001 Sponsored by the Association for Computational Linguistics Special Interest Group on the Lexicon. Previously announced as two different workshops: - WordNet: Extensions and NLP Applications - Customizing Lexical Resources Lexical resources have become important basic tools within NLP and related fields. The range of resources available to the researcher is diverse and vast - from simple word lists to complex MRDs and thesauruses. The resources contain a whole range of different types of explicit linguistic information presented in different formats and at various levels of granularity. Also, much information is left implicit in the description, e.g. the definition of lexical entries generally contains genus, encyclopaedic and usage information. The majority of resources used by NLP researchers were not intended for computational uses. For instance, MRDs are a by-product of the dictionary publishing industry, and WordNet was an experiment in modelling the mental lexicon. In particular, WordNet has become a valuable resource in the human language technology and artificial intelligence. Due to its vast coverage of English words, WordNet provides with general lexico-semantic information on which open-domain text processing is based. Furthermore, the development of WordNets in several other languages extends this capability to trans-lingual applications, enabling text mining across languages. For example, in Europe, WordNet has been used as the starting point for the development of a multilingual database for several European languages (the EuroWordNet project). Other resources such as the Longman Dictionary of Contemporary English and Roget's Thesaurus have also been used for various NLP tasks. The topic of this workshop is the exploitation of existing resources for particular computational tasks such as Word Sense Disambiguation, Generation, Information Retrieval, Information Extraction, Question Answering and Summarization. We invite paper submissions that include but are not limited to the following topics: - Resource usage in NLP and AI - Resource extension in order to reflect the lexical coverage within a particular domain; - Resource augmentation by e.g. adding extra word senses, enriching the information associated with the existing entries. For instance, recently, several extensions of the WordNet lexical database have been initiated, in the United States and abroad, with the goal of providing the NLP community with additional knowledge that models pragmatic information not always present in the texts but required by document processing; - Improvement of the consistency or quality of resources by e.g. homogenizing lexical descriptions, making implicit lexical knowledge explicit and clustering word senses; - Merging resources, i.e. combining the information in more than one resource e.g. by producing a mapping between their senses. For instance, WordNet has been incorporated in several other linguistic and general knowledge bases (e.g. FrameNet and CYC); - Corpus-based acquisition of knowledge; - Mining common sense knowledge from resources; - Multilingual WordNets and applications; Paper submission Submissions must use the NAACL latex style or Microsoft Word style. Paper submissions should consist of a full paper (6 pages or less).

cs.rutgers.edu>_______________________________________________________________ * Note deadline extension! * NAACL 2001 Workshop on Adaptation in Dialogue Systems Webpage: www.cs.utah.edu/~cindi/AdaptDial.html Overview The purpose of this workshop is to bring together researchers investigating the application of learning and adaptation to dialogue systems, both speech and text based. Methods for learning and adaptation show promise for enhancing the robustness, flexibility, and overall accuracy of dialogue systems. While researchers in many parts of computational linguistics who use these methods have begun to form communities, the burgeoning set of activities within dialogue has remained relatively disparate. We are interested in adaptation that includes learning procedures as well as decision making methods aimed at dynamically reconfiguring dialogue behavior based on the context. We would also like to explore techniques that allow a dialogue system to learn with experience or from data sets gathered from empirical studies. Researchers looking at methods to automatically improve different modules of dialogue systems, or the system as a whole, have not had many opportunities to come together to share their work. We thus welcome submissions from researchers supplementing the traditional development of dialogue systems with techniques from machine learning, statistical NLP, and decision theory. Call For Papers We solicit papers from a number of research areas, including: - Use of machine learning techniques at all levels of dialogue, from speech recognition to generation; from dialogue strategy to user modeling - Adapting to the user as a dialogue progresses - Dialogue as decision making under uncertainty - User and user group modeling - Use of corpora in developing components of dialogue systems, including issues in annotation - Evaluation of adaptive dialogue systems - Comparison of different techniques in applying adaptive techniques to dialogue We also hope to include a session for the demonstration of working systems, as time permits. The demonstration sessions will be open to anyone who wishes to bring their adaptive conversational systems for demonstration to other members of the workshop. Presenters are asked to submit a paper that is specifically directed at a demonstration of their current systems. Important Dates (2001): Paper submission deadline: Feb 19 Notification of acceptance for papers: Mar 16 Camera ready papers due: Mar 30 Workshop date: Jun 4 Paper Submission Electronic submission strongly preferred. We will be setting up an email alias in the next several days for paper submission. Please check with the web page for developments. Submissions must use the NAACL latex style or Microsoft Word style. Paper submissions should consist of a full paper (6 pages or less). The templates are available at the workshop web site.
