WordNet and Other Lexical Resources: Applications, Extensions and Customizations NAACL 2001 Workshop Carnegie Mellon University, Pittsburgh 3 and 4 June, 2001 http://www.seas.smu.edu/~moldovan/mwnw/ 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). NAACL style file NAACL bibliography style file Latex sample file Microsoft Word Template file Submission procedure Electronic submission only. For U.S. papers please send the pdf or postscript file of your paper to: moldovan@seas.smu.edu. Please submit papers from other countries to w.peters@dcs.shef.ac.uk. Because review is blind, no author information is included as part of the paper. A separate identification page must be sent by email including title, all authors, theme area, keywords, word count, and an abstract of no more than 5 lines. Late submissions will not be accepted. Notification of receipt will be e-mailed to the first author shortly after receipt.
