dc.fi.udc.es>- -------------------------------------------------------------------- TAPD2000 2nd Workshop on 'Tabulation in Parsing and Deduction' - -------------------------------------------------------------------- September 2000 Vigo, Spain Sponsored by University of Vigo WEB page: http://coleweb.dc.fi.udc.es/tapd2000/ Following TAPD'98 in Paris (France) next TAPD event will be held in Vigo (Spain), in September, 2000. MOTIVATIONS: Tabulation techniques are becoming a common way to deal with highly redundant computations occurring, for instance, in Natural Language Processing, Logic Programming, Deductive Databases, or Abstract Interpretation, and related to phenomena such as ambiguity, non-determinism or domain ordering. Different approaches, including for example Chart Parsing, Magic-Set rewriting, Memoization, and Dynamic Programming, have been proposed whose key idea is to keep traces of computations to achieve computation sharing and loop detection. In addition, tabulation also offers more flexibility to investigate new parsing or proof strategies and to represent ambiguity by shared structures (Shared Proof or Parse Forest). The first objective of this workshop is to compare and discuss these different approaches. The second objective is to present tabulation and tabular systems to potential users in different application areas. One major area of application is Natural Language Processing, where tabulation has been known for a long time (CKY, Earley, chart parsing). However, sophisticated tabulation techniques are required for the more and more complex grammatical formalisms now used in NLP (unification, constraints, structural complexity). Contributions in other areas, such as picture parsing, genome analysis, or complete deduction techniques, are also encouraged. TOPICS (not exclusive): -- Tabulation Techniques: Chart Parsing, Tabling, Memoization, Dynamic Programming, Magic Set, Generic Fix-Point Algorithms -- Applications: Parsing, Generation, Logic Programming, Deductive Databases, Abstract Interpretation, Deduction in Knowledge Bases, Theorem Proving -- Static Analysis: Improving tabular evaluation -- Parsing or resolution strategies. -- Efficiency issues: Dealing with large tables (structure sharing, term indexing), Execution models, Exploiting the domain ordering (subsumption). -- Shared structures (parse or proof forest): Formal analysis, representation and processing. WORKSHOP FORMAT: The workshop will be a 3-day event that provides a forum for individual presentations of the accepted contributions as well as group discussions. SUBMISSION PROCEDURE: Authors are invited to submit before April 28 a 4-page position paper or abstract concerning a theoretical contribution or a system to be presented. Due to tight time constraints, submission and reviewing will be handled exclusively electronically (LaTeX, PostScript, dvi or ascii format). Submission should include the title, authors' names, affiliations, addresses, and e-mail. The submissions must be sent to David S.

dc.fi.udc.es>- -------------------------------------------------------------------- SEPLN 2000 XVI Conference of the Spanish Society for Natural Language Processing - -------------------------------------------------------------------- September 2000 Vigo, Spain Sponsored by Universidade de Vigo WEB Page: http://coleweb.dc.fi.udc.es/sepln2000/ Following SEPLN'99 in Lleida (Spain), the next SEPLN event will be held in Vigo (Spain), in September, 2000. MOTIVATIONS The motivation for this Conference is to provide researchers in the field of Natural Language Processing a chance to present their recent work, to share their experimental results, and to discuss a range of problems which must be treated. Moreover, for researchers not directly involved within the field of natural language processing, presentations shall offer the opportunity to realize the active state of the art research, together with present applications and possibilities offered by this field. Thus, an important objective of this Conference is to promote the exchange of ideas and opinions for future basic research directions and to compare these ideas with the actual needs of the society. AREAS OF INTEREST 1. Linguistic, mathematic and psicolinguistic models of languages. 2. Corpus linguistics 3. Information extraction and retrieval 4. Formalisms and grammars for morphological and syntactical analysis 5. Computational lexicography 6. Monolingual and multilingual textual generation 7. Automatic translation 8. Speech synthesis and recognition 9. Semantics, pragmatics and discourse PROJECTS AND DEMOS The organizers encourage participants to give oral presentations of projects and demos. Depending on the estimated number of oral presentations, some session may be reserved to this purpose. For oral presentation of projects to be accepted, the following information must be included: - Project title - Funding institution - Participant groups in the project - Name, affiliation, e-mail and phone number of the director of the project. - Abstract (2 pages maximum). - If a demonstration is to be performed, further information must be included, as indicated below. For demonstrations to be accepted, the following information is mandatory: - Name, affiliation, e-mail and phone number of the authors. - Abstract (2 pages maximum). - Time estimation for the whole presentation. This information must be received by June 4, 2000. CONFERENCE FORMAT The workshop will be a 3-day event that provides a forum for individual presentations of the accepted contributions as well as project an demos presentations and group discussions. SUBMISSION PROCEDURE Authors are invited to submit a paper, before April 14, concerning a theoretical contribution or a system to be presented. Submission and paper reviews shall be handled exclusively electronically (PostScript or PDF format). Submission should include the title, authors' names, affiliations, addresses, and e-mail. The submissions must adhere to certain rules: - They must include an abstract (150 word maximum). - The proposed area of interest must be included. - Maximum length is 3500 words, abstract included. - Accepted papers must follow format rules that will be given in the conference web page (http://coleweb.dc.fi.udc.es/sepln2000/).
