From: Susan Emilie Manus Subject: Call for Papers: ISMIR 2003 - Int'l conference on music ISMIR 2003 - 4th International Conference on Music Information Retrieval http://ismir2003.ismir.net/ October 26-30, 2003 Library of Congress, Washington, D.C., USA and Johns Hopkins University, Baltimore, Maryland, USA Call for Papers, Posters, Tutorials, Panels and Exhibits ========================================================= The annual ISMIR Conference is the first established international forum for those involved in work on accessing digital musical materials. It reflects the tremendous growth of music-related data available either locally or remotely through networks and the consequent need to search this content and retrieve music and musical information efficiently and effectively. This area presents vast challenges for those who need to organize and structure musical data, provide tools to search and retrieve, and use these tools efficiently. Music representation needs to be multi-dimensional and time-dependent; audio data is voluminous, requiring particular care in storage and transmission while preserving quality; the need for descriptive information about what is musically significant addresses a large spectrum of internal and external characteristics, from acoustic to musicological and cultural features; intellectual property rights issues (about what can be made available to whom and how) are complex, involve a variety of individuals and organizations, and vary from country to country. All of these concerns are of interest to education, academia, entertainment and industry. This conference thus aims at providing a place for the exchange of news, issues and results, by bringing together researchers and developers, educators and librarians, students and professional users, working in fields that contribute significantly to this multidisciplinary domain, to present original theoretical or practical work in peer-reviewed contributions (papers, posters). It will also serve as a discussion forum (panels), provide introductory and in-depth information in specific domains (tutorials), and show current products (exhibits). Detailed information about the conference and its organization is available on its Web site (http://ismir2003.ismir.net/). Domains and Topics of Interest ============================== ISMIR 2003 solicits original contributions in the following domains, as they apply to music information retrieval(this is a non-exclusive list): * Algorithms and methods for classification, clustering, probabilistic modelling, association analysis * Artificial intelligence and Machine Learning * Databases and data mining * Human-Computer Interaction (HCI) and systems design * Intellectual property rights issues * Knowledge representation, discovery and acquisition * Music perception and cognition * Music representation and formal models of music * Soft computing (neural networks, fuzzy systems, evolutionary computation) Typical topics of interest, inasmuch as they relate to music information retrieval, are: * Automatic summarization, citing, excerpting, downgrading, transformation (including associated intellectual property issues) * Business models and experience * Formal models of music and their digital representations * Intellectual property rights issues (nationally and internationally), digital rights management, identification and traceability * Music digital libraries and archives, content management systems and frameworks for music * Music indexing and metadata (authoring and generation) * Music recognition (printed, audio) * Music representation, coding, language modelling * Music similarity metrics (perceptual criteria such as pitch, rhythm, timbre; musical criteria such as form, genre, etc.) * Musical styles and genres * Query languages for music IR (expressiveness, complexity) * Real-time applications of automated music identification and recognition, such as score following, automatic accompaniment * Routing and filtering for music and music queries * Semantic Web and musical digital objects: intelligent agents, ontologies, topic maps, metadata, indexation, markup languages * Socio-cultural aspects * Standards (RDF, XML, INDECS, MPEG, Dublin Core, *MARC, Z39.50...) and other metadata or protocols for music information handling and retrieval (CDDB, ...) * Systems issues (performance, compression, scalability, databases, architecture, distributed search, multi-agent systems, mobile applications) * User interfaces and usability * Validation (user needs and expectations, evaluation of music IR systems, building test collections, experimental design and metrics) General information on the conference is available on its Web site (http://ismir2003.ismir.net/) and will be regularly posted in the music-ir mailing list (information on subscription available on the conference site).

From: Juan Manuel Fernández-Luna Subject: Call for Papers: Special Issue of IP&M: Bayesian Networks and IR ------------------------------------------------------------------ Special Issue of IP&M: Bayesian Networks and Information Retrieval ------------------------------------------------------------------ --------------- Call for Papers --------------- Special Issue of Information Processing and Management on BAYESIAN NETWORKS AND INFORMATION RETRIEVAL DEADLINE FOR SUBMISSION JULY 1, 2003 Since the very first studies about the application of Belief Networks to Information Retrieval, a great number of researchers have been developing successful retrieval models based on these graphical models until nowadays, as well as solutions to specific problems found in this field. Taking into account that these tools show a high performance in problems in which uncertainty is a very important feature, Information Retrieval is presented as a very attractive test bed because it is strongly pervaded by this property, presenting very interesting challenges that classical solutions have not solved at all. This Special Issue of Information Processing and Management aims at presenting a landmark set of research papers which show the best research in the field on different aspects of the application of Belief Networks to Information Retrieval, not only focused to the classical retrieval, but also dealing with solutions to current subfields as Structured Documents, Cross-Language Information Retrieval or new technologies as MPEG-7, among others, where an intensive research is being carried out. Suggested topics include, but are not limited to: * Information Retrieval Models applied to classical document collections. * Information Retrieval Models for structured document collections based on SGML, XML, etc. * Cross-language retrieval. * Document classification, clustering and filtering. * Web retrieval. * Applications to hypertext. * Indexing and summarization. * Multimedia information access, as video, audio, image retrieval, also applied to new technologies as MPEG-7 videos.

Advances in information visualization point to new possibilities for developing enhanced interfaces for improving retrieval, manipulation, and management of data stored in digital libraries. The IVIRA workshop will cover both theoretical and experimental research on the development, usage, and evaluation of effective interfaces to digital libraries. Of particular interest is research that exploits visualization to support improved browsing, retrieval, analysis, and understanding of domains represented in digital libraries. Interfaces for the following types of resources are of special interest to this workshop: - Textual documents (literature databases) - Statistical data - Multimedia or mixed-media data - Geo-spatial data - Genomics and proteomics data - Time-variant or dynamic data Papers are invited from researchers and practitioners with expertise and interest in information visualization, user interfaces for DLs, search/retrieval, human-computer interaction, interface design methodologies, and evaluation. Submission Selection You are invited to submit a position paper by May 5th, 2003. All submitted papers will be peer-reviewed. No late submissions will be accepted. IVIRA will accept electronic submissions in PDF format only. Papers should be no longer than 2-6 pages and conform to the format specified in the template (see http://www.ils.unc.edu/jcdl2002/cfp.doc). Please submit your paper as an attachment to: jm@indiana.edu.
