ilc.pi.cnr.it>*************** EXTENDED DEADLINE **************** - --- NEW DEADLINE: APRIL 23rd ----- - --- Please check new dates below! ----- SEMANTIC KNOWLEDGE ACQUISITION AND CATEGORISATION Workshop at ESSLLI XIII (Helsinki) Helsinki, August 13th - 17th 2001 http://www.ilc.pi.cnr.it/~esslli - ------------------------------------------------------------- Endorsed by SIGSEM, the ACL Special Interest Group on computational semantics - ------------------------------------------------------------- The sheer amount of knowledge necessary to shed light on the way word meanings mutually relate in context or distribute in lexico-semantic classes appears to exceed the limits of human conscious awareness and descriptive capability. Particularly at this level of linguistic analysis, then, we seem to be in need of automatic ways of filtering, structuring and classifying semantic evidence through inspection of a large number of word uses in context. Totally or partially unsupervised inductive methods of knowledge acquisition from corpus data are credited with being able to provide such ways. Yet, it remains to be seen how acquired information can best be represented in current formal models for knowledge representation, for it to be made available to mainstream NLP applications. There are reasons to believe that this integration will require much more than a simple extension of off-the-shelf machine learning technology. At the same time, any major breakthrough in this area is bound to have significant repercussions on the way word meanings and lexico-semantic classes in general are formally represented and used for applications. With these purposes in mind, the workshop intends to focus on the issue of interaction between techniques for inducing semantic information from corpus data and formal methods of linguistic knowledge representation. In particular, we encourage in-depth analysis of underlying assumptions of the proposed techniques and methods and discussion of possible relevant connections with cognitive, linguistic,logical and philosophical issues. TOPICS OF INTEREST Possible themes for contributions are: - development of 'data-driven' semantic type systems - dynamic update and tuning of formal ontologies with text data - 'hybrid models' of knowledge extraction, whereby machine learning methods are integrated with formal structures of knowledge representation - creation of dynamic lexical knowledge-bases - formal representation and structuring of the flow of information extracted from texts. WORKSHOP ORGANISATION The workshop will be held on five subsequent days, August 13th-17th 2001. It will take place during the ESSLLI-Summer School in Helsinki, and will be open to all members of the LLI-community, computational linguistics and cognitive science as well. Each session will consist of two talks plus discussion (30mins + 15mins each). The workshop language will be English. - -------------------------------------------------------------------------- GUIDELINES FOR SUBMISSIONS The organizers welcome contributions from different fields of computational linguistics, logic and cognitive science. 1. Submissions will consist of full papers reporting on original, unpublished works. Papers should not exceed 5000 words (including references), must contain a 5-10 lines abstract, and must be submitted in postscript format 2. The reviewing of papers will be blind. Hence the paper should not include the authors' names and affiliations. Furthermore, self-references that reveal the author's identity should be avoided. 3. Identification information will be put in a separate file consisting of: Title of the paper: Author(s): Affiliation(s): E-mail(s): Abstract: 4. Submitted papers and identification information must be sent to the following address by APRIL 23rd 2001: esslli2001Mail to author|Respond to list|Read more issues|LINGUIST home page|Top of issue
kub.nl>- ------------------------------------------------------------------------- C a l l f o r P a p e r s IWPT 2001 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 7th International Workshop on Parsing Technologies ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Sponsored by ACL/SIGPARSE 17-19 October, 2001 Beijing, China http://www.icl.pku.edu.cn/iwpt2001.html ~~~~ The Institute of Computational Linguistics, Peking University, Beijing, China, will host the 7th International Workshop on Parsing Technologies (IWPT'01) from 17 to 19 October, 2001. IWPT'01 continues the tradition of biennial workshops on parsing technology organised by SIGPARSE, the Special Interest Group on Parsing of the Association for Computational Linguistics (ACL). This workshop series was initiated by Masaru Tomita in 1989. The first workshop, in Pittsburgh and Hidden Valley, was followed by workshops in Cancun (Mexico) in 1991; Tilburg (Netherlands) and Durbuy (Belgium) in 1993; Prague and Karlovy Vary (Czech Republic) in 1995; Boston/Cambridge (Massachusetts) in 1997; and Trento (Italy) in 2000. Topics of interest for IWPT'01 - ------------------------------ Topics of interest for IWPT'01 include, but are not limited to: theoretical and practical studies of parsing algorithms for natural language sentences, texts, fragments, dialogues, ill-formed sentences, speech input, multi-dimensional (pictorial) languages, multimedia (web) documents, and parsing issues arising or viewed in a multimodal context. Both grammar-based and statistical approaches are welcome. Submitting Papers - --------------- Two types of submissions are invited: - full papers, to be presented as such during the workshop and to be published in the workshop proceedings (maximally 12 pages); - short papers, to be presented at the workshop in the form of a poster plus a summary oral presentation in a short-paper session; two-page summaries are published in the workshop proceedings. Prospective authors are invited to send submissions to the IWPT'01 programme chairman Giorgio Satta. Papers must be in the format given at the IWPT'01 home pages (see below). Full papers should not exceed 12 pages; short papers should not exceed 1500 words. Submission is electronically, in postscript form. Only in case electronic submission is impossible, four (4) hard copies of the paper should be sent.
