ACM SIGIR '99 Second Call for Participation UC Berkeley, CA, USA August 15-19, 1999 New paper submission deadline: January 12, 1999 http://www.sims.berkeley.edu/conferences/sigir99 The Twenty-Second Annual International ACM-SIGIR Conference on Research and Development in Information Retrieval, will be held on the campus of the University of California at Berkeley, August 15-19, 1999, with accommodation at nearby hotels. SIGIR is the premiere international forum for the presentation of new research results and for the demonstration of new systems and techniques in information retrieval. The conference attracts a broad range of professionals including theoreticians, developers, publishers, researchers, educators, and designers of systems, interfaces, information bases, and related applications. In 1999, in addition to the standard core set of Information Retrieval topics, SIGIR strongly encourages contributions from two major areas: Human Computer Interaction in Information Access and Multi-Media Retrieval. ** Note: the submission deadline for research papers has changed to January 12, 1999. ** To receive SIGIR '99 announcements, send mail to: majordomo@sims.berkeley.edu containing the one line message: subscribe sigir99-announce HCI and IR There is a growing opinion in the Information Retrieval community that a key to improving information access systems is to focus attention on the human-computer interface. Additionally, the World Wide Web is opening up new opportunities for design, dissemination and evaluation of user interfaces for information access. The IR community has much to learn from the HCI community; conversely IR research has for many years investigated user needs and user information seeking behavior, typically in the context of online bibliographic systems. Thus the HCI community can benefit from this experience as well. One goal of SIGIR'99 is to bring these two communities closer together. Thus, human computer interaction in information retrieval will be a major theme for SIGIR'99. Topic relevant to the intersection of HCI and IR include, but are not limited to: Evaluation of human-computer interfaces for information access. Information seeking models and user interfaces for information access. Information structure for navigation and search. These are described in more detail in the HCI and IR supplement. See http://www.sims.berkeley.edu/conferences/sigir99 General IR Authors are encouraged to submit high-quality papers about original research in information systems, and theories, models, and implementations of IR systems. Topics traditionally relevant to SIGIR include but are not limited to: IR Theory including statistical and logical IR models, data fusion. Experimentation, including test collections, evaluation measures, scalability. Systems and Implementation Issues Natural Language Processing for the purposes of IR Filtering, Routing, and Text Classification. Applications, e.g. : task-embedded IR, electronic publishing, digital libraries, text data mining. These are described in more detail at http://www.sims.berkeley.edu/conferences/sigir99 Multi-Media Information Retrieval The Multi-Media Information Retrieval Theme of SIGIR'99 specifically addresses the overlap between multi-media data and information retrieval, and so we discourage contributions that focus purely on algorithms for processing multi-media data without regard for the information retrieval problems being addressed. We also discourage contributions that focus only on the system and software aspects of storing and managing large amounts of these data types. We welcome high-quality papers that describe evaluation experiments, case studies, and theoretical analyses. We especially encourage submissions from researchers not traditionally part of the SIGIR community who are nevertheless doing significant information retrieval work. Topics include but are not limited to: Content-based Indexing Strategies Query Formulation and Query Languages for MMIR Cross-Media and Mixed-Media Retrieval Results Analysis and Presentation for MMIR Test Collection Development and Evaluation for MMIR See Multi-Media IR for more information about relevant topics. These are described in more detail in the Multi-Media and IR supplement. http://www.sims.berkeley.edu/conferences/sigir99
