NIIの江口と申します． IRAL2003という国際ワークショップのCFPをご案内いたします． ACL2003と連続して札幌にて開催される予定です． DBS研が協賛団体の一つとなっております．是非ご投稿ください． ____________________________________________________ 江口浩二＠国立情報学研究所 E-mail: eguchi(a)nii.ac.jp ======== CALL FOR PAPERS The Sixth International Workshop on Information Retrieval with Asian Languages - IRAL2003 7 July, 2003 Sapporo Convention Center, Sapporo, JAPAN Sponsored by National Institute of Informatics, Japan In cooperation with: ACM SIGIR Japanese Association for Natural Language Processing(pending) SIG-DBS, Information Processing Society of Japan(pending) SIG-KLP, Korea Information Science Society (pending) SIG-NLP, Information Processing Society of Japan(pending) Singapore Computer Society(pending) URL: http://research.nii.ac.jp/IRAL2003 ABOUT THE WORKSHOP The purpose of the IRAL is to bring together researchers and developers who are interested in exchanging new ideas and presenting results in the field of information retrieval with an emphasis on the issues related to Asian languages and multilingual applications. The first workshop was held in Korea, 1996, and then we had 4 more workshops in Japan, Singapore, Taiwan and Hong Kong. Unfortunately, because of organizing difficulties in the steering committee members of participating Asian countries, we could not hold workshops in 2001 and 2002. In IRAL2000 in Hong Kong, we collocated the workshop just before ACL2000. In the Year 2003, we have ACL2003 in Sapporo, Japan (http://www.ec-inc.co.jp/ACL2003/) and we proposed to have IRAL workshop as one of ACL supported workshops. We regard having our workshop within ACL2003 as a good chance to restart periodical gathering of IR research community. Best papers will be considered for publication in ACM Transactions on Asian Language Information Processing (TALIP), http://www.cintec.cuhk.edu.hk/~talip. TOPICS IRAL2003 welcomes submissions of original papers in the broad field of information storage and retrieval, but topics contributed to Asian languages are encouraged. The technical issues to be addressed include, but are not limited to: IR theory Experimentation: test collection, corpus, evaluation methodology Systems and Implementation issues: integration with network and database system. Natural language processing related issues: Questioning and Answering, summarization, cross-lingual IR, term extraction Information filtering, routing and text classification Application of IR technology Web related issues: web mining, search engine, INSTRUCTIONS FOR SUBMISSION OF PAPERS: Authors of papers are invited to submit original contributions, not exceeding 5000 words in English to the Program Chair of IRAL2003 by e-mail. Details such as electronic submission and style files will be announced on the IRAL2003 home page.

dbjapan, sigmod-j, DLnet-forum各位（重複して受け取られた方はご容赦下さい）名大の吉川です． 3月末に京都で開催されるDASFAA2003への参加をお誘い致します． DASFAAはアジア・オセアニア地区において隔年ごとに開催されてきたデータベースの国際会議です．回を重ねるごとに会議の重要性も増してきており，今回は論文の採択倍率が3倍以上になりました！！アジア・オセアニアにとどまらず，欧米からも最先端の論文が数多く発表されます．データベース分野の最先端情報を得るために，桜が満開（のはず）の京都へ是非お出かけ下さい． DASFAA2003 Program Co-Chair 吉川正俊 -------------------------------------------------------------------------- CALL FOR PARTICIPATION 8th International Conference on Database Systems for Advanced Applications (DASFAA 2003) March 26-28, 2003, Kyoto, Japan http://db-www.aist-nara.ac.jp/dasfaa2003/ Organized by Kyoto University DASFAA Steering Committee Sponsored by Communications Research Laboratory Hitachi, Ltd. Kyoto University Supported by Information Processing Society of Japan (IPSJ), SIGDBS Database Society of Japan (DBSJ) ---------------------- AIMS OF THE CONFERENCE ---------------------- This conference provides an international forum for technical discussion among researchers, developers and users of database systems from academia, business and industry. DASFAA focuses on research in database theory, development of advanced DBMS technologies, and their advanced applications. --------------- INVITED SPEAKER --------------- Professor Jeffrey D. Ullman (Stanford University) "A Survey of New Directions in Database Systems" ------------ REGISTRATION ------------ Visit http://db-www.aist-nara.ac.jp/dasfaa2003/ for information about registration and accommodation. ---------------- CONFERENCE VENUE ---------------- Campus Plaza Kyoto Nishino Touin Dori, Shio Kouji Sagaru, Shimogyo-Ku, Kyoto 600-8216, Japan TEL +81-75-353-9120, FAX +81-75-353-9121 Campus Plaza Kyoto is 200m west of JR Kyoto Station North Entrance. ------------- TRAVEL ADVICE ------------- - From Tokyo to Kyoto Station, it takes about 2 and a half hours by Shinkansen. - From Kansai International Airport, take JR (Japan Railway) Airport Limited Express Train, HARUKA, which runs every 30 minutes. The traveling time to Kyoto JR station is approximately 75 minutes and fare is 3,490 yen (reserved seats), or 2,980 yen (non-reserved seats). Participants from foreign countries can purchase JAPAN RAIL PASS, which is a special discount pass for any trains of JR Group Railways (except the NOZOMI super express). JAPAN RAIL PASS is sold only outside of Japan: Must be purchased before arriving in Japan. For details, check website: http://www.japanrailpass.net/ ---- VISA ---- For entering Japan, you need a valid passport and in some cases a visa. To check whether you need a visa, and how to apply it, visit the homepage of the Ministry of Foreign Affairs (http://www.mofa.go.jp/j_info/visit/visa/index.html) Obtaining a visa may take a long period of time, a few months in some cases. So apply immediately if you need a visa. Ask Japanese Embassies/Consulates or local travel agencies for necessary documents. If you need a letter from the DASFAA2003 General Chair for visa application, please send mail to: dasfaa03(a)is.aist-nara.ac.jp ------------------ CONFERENCE PROGRAM ------------------ March 26 (Wed.) 9:30-10:30 Keynote: A Survey of New Directions in Database Systems Jeffrey D. Ullman (Stanford University) Abstract: As database system research evolves, there are several enduring themes. One, of course, is how we deal with the largest possible amounts of data. A less obvious theme is optimization --- it is an essential ingredient of all modern forms of database system. Because we deal with large volumes of data, we are often forced to process that data in regular ways. But when operations are uniform, there is an opportunity for the use of very-high-level languages, of which SQL is the primary example. However, to make a very-high-level language effective, we need to optimize it well, that is, produce effective query plans from all sorts of queries. In this talk, we shall review the principal directions in which modern database research is going, and in each case talk a bit about the optimization problems. Stream management systems are one very important new area. Another is peer-to-peer database systems. Integration of heterogeneous information, especially in virtual databases, is also a major challenge. XML, XQUERY, and semistructured data in general form yet another research opportunity. 10:50-12:20 Session 1: Spatial Query Processing Similarity Join for Low- and High- Dimensional Data Dmitri V.
