Abstract

Proceedings of the llth TREC-conference held in Gaithersburg, Maryland (USA), November 19-22, 2002. Aim of the conference was discussion an retrieval and related information-seeking tasks for large test collection. 93 research groups used different techniques, for information retrieval from the same large database. This procedure makes it possible to compare the results. The tasks are: Cross-language searching, filtering, interactive searching, searching for novelty, question answering, searching for video shots, and Web searching.

Footnote

Rez. in: JASIST 58(2007) no.3, S.457-458 (A.M.A. Ahmad): "The concept of the semantic web has emerged because search engines and text-based searching are no longer adequate, as these approaches involve an extensive information retrieval process. The deployed searching and retrieving descriptors arc naturally subjective and their deployment is often restricted to the specific application domain for which the descriptors were configured. The new era of information technology imposes different kinds of requirements and challenges. Automatic extracted audiovisual features are required, as these features are more objective, domain-independent, and more native to audiovisual content. This book is a useful guide for researchers, experts, students, and practitioners; it is a very valuable reference and can lead them through their exploration and research in multimedia content and the semantic web. The book is well organized, and introduces the concept of the semantic web and multimedia content analysis to the reader through a logical sequence from standards and hypotheses through system examples, presenting relevant tools and methods. But in some chapters readers will need a good technical background to understand some of the details. Readers may attain sufficient knowledge here to start projects or research related to the book's theme; recent results and articles related to the active research area of integrating multimedia with semantic web technologies are included. This book includes full descriptions of approaches to specific problem domains such as content search, indexing, and retrieval. This book will be very useful to researchers in the multimedia content analysis field who wish to explore the benefits of emerging semantic web technologies in applying multimedia content approaches. The first part of the book covers the definition of the two basic terms multimedia content and semantic web. The Moving Picture Experts Group standards MPEG7 and MPEG21 are quoted extensively. In addition, the means of multimedia content description are elaborated upon and schematically drawn. This extensive description is introduced by authors who are actively involved in those standards and have been participating in the work of the International Organization for Standardization (ISO)/MPEG for many years. On the other hand, this results in bias against the ad hoc or nonstandard tools for multimedia description in favor of the standard approaches. This is a general book for multimedia content; more emphasis on the general multimedia description and extraction could be provided.

Abstract

Held for the first time in the United States, the Conference on Conceptions of Library and Information Science (CoLIS4) is the fourth in the series of international conferences that bring together leading researchers from around the world. CoLIS4 provides a forum for critically exploring and analyzing library and information science as a discipline and as a field of research from historical, philosophical, theoretical, and methodological perspectives. The papers in this volume cover a wide variety of topics, presenting the latest research and information on new developments and new approaches to conceptual frameworks and methods in library and information science. Papers range from a re-examination of the core concepts to empirical studies, analyzing such areas as Web searching, information retrieval, informetrics, information behavior, aspects of learning, business intelligence, and information processing mechanisms. As library and information science is closely associated with a variety of other disciplines and its practice employs technologies that are changing rapidly, presenters focus on the old and the new, address theory and practice, and bridge diverse intellectual areas. From challenging existing approaches and proposing new ones to establishing models and reviewing methods-the presenters lead the way to change and further exploration.

Themes and questions threaded throughout the conference papers and panels addressed the uniqueness of LIS as a contemporary "intersection of information, technology, people, and society" (CoLIS Proceedings Preface). Papers by Birger Hjørland and by Sanna Talja, Kimmo Tuominen, and Reijo Savolainen directly addressed the essential nature and metatheory of LIS as a field of inquiry by reviewing its theoretical models and epistemological perspectives, such as the information transfer model and socio-cognitive theory. The cognitive grounding of much LIS research was present in Pertti Vakkari's and Mikko Pennanen's study linking university students' concept formation with their search processes and task performances while preparing research proposals, as well as in Peter Ingwersen's analysis of the cognitive conception of document polyrepresentation (multiple ways of representing documents) applied to information retrieval. A number of papers presented empirically and theoretically derived taxonomies of the fundamental characteristics of information bearers (documents and systems) and information behaviors (both individual and collaborative). These mark a contemporary effort to enumerate and classify the elements that LIS researchers should be examining and with which they should be building systems and generating theory. Nicholas Belkin and Colleen Cool reported on field research with which they are constructing a taxonomy of interactions in information seeking and communication behavior, to be used to inform information system building. Rong Tang presented her taxonomic study of Web searching query patterns and argued for the need to link these to user cognitive operations and search tasks. Linda Cooper explored school children's categorizations and knowledge of information organization in libraries by having them arrange books and topics visually and spatially on "virtual" bookshelves. Kartriina Byström and Preben Hansen proposed a nested typology of the concepts of work tasks, information seeking tasks, and information retrieval tasks as units of analysis for LIS research. Work task and domain analysis figured importantly in several papers, reflecting a increasing application of information context research approaches. In addition to Byström and Hansen's theoretical study of the concepts of tasks in general, the work reported by researchers at Risø National Laboratory, Denmark (Annelise Mark Pejtersen, Bryan Cleal, Morten Hertzum, Hanne Albrechtsen) demonstrated the application of the Cognitive Work Analysis (CWA) framework used to inform the design of a virtual "collaboratory" used by three European film archives. Birger Hjørland asserted that domain analysis, including the study of the interests, goals, values, and consequences of information use and users in specific subject and work domains, is central to the practice of LIS.
LIS research and evaluation methodologies fell under the same scrutiny and systematization, particularly in the presentations employing multiple and mixed methodologies. Jaana Kekäläinen's and Kalervo Järvelin's proposal for a framework of laboratory information retrieval evaluation measures, applied along with analyses of information seeking and work task contexts, employed just such a mix. Marcia Bates pulled together Bradford's Law of Scattering of decreasingly relevant information sources and three information searching techniques (browsing, directed searching, and following links) to pose the question: what are the optimum searching techniques for the different regions of information concentrations? Jesper Schneider and Pia Borlund applied bibliometric methods (document co-citation, bibliographic coupling, and co-word analysis) to augment manual thesaurus construction and maintenance. Fredrik Åström examined document keyword co-occurrence measurement compared to and then combined with bibliometric co-citation analysis to map LIS concept spaces. Ian Ruthven, Mounia Lalmas, and Keith van Rijsbergen compared system-supplied query expansion terms with interactive user query expansion, incorporating both partial relevance assessment feedback (how relevant is a document) and ostensive relevance feedback (measuring when a document is assessed as relevant over time). Scheduled in the midst of the presentations were two stimulating panel and audience discussions. The first panel, chaired by Glynn Harmon, explored the current re-positioning of many library and information science schools by renaming themselves to eliminate the "library" word and emphasize the "information" word (as in "School of Information," "Information School," and schools of "Information Studies"). Panelists Marcia Bates, Harry Bruce, Toni Carbo, Keith Belton, and Andrew Dillon presented the reasons for name changes in their own information programs, which include curricular change and expansion beyond a "stereotypical" library focus, broader contemporary theoretical approaches to information, new clientele and markets for information services and professionals, new media formats and delivery models, and new interdisciplinary student and faculty recruitment from crossover fields. Sometimes criticized for over-broadness and ambiguity-and feared by library practitioners who were trained in more traditional library schools-renaming schools both results from and occasions a renewed examination of the definitions and boundaries of the field as a whole and the educational and research missions of individual schools.

Abstract

Problems of indexing and searching free-text data bases are discussed in detail. The possibilities and limitations of Boolean searching are shown. An experimental system COPSY (Context operator syntax) that was built in order to avoid common errors connected with Boolean search is outlined. This system permits, as input, any natural language search question formulation and yields, as output, documents ranked on the basis of an automatically calculated correspondence between natural language search questions and content-based analysis of documents. COPSY is part of a text processing project at Siemens AG called TINA (Text-Inhalts-Analyse...). Software from TINA is actually being applied and evaluated by the US Department of Commerce for patent searching and indexing.

Abstract

A retrieval experiment was conducted to compare on-line searching using terms opposed to citations. This is the first study in which a single data base was used to retrieve two equivalent sets for each query, one using terms found in the bibliographic record to achieve higher recall, and the other using documents. Reports on the use of a second citation searching strategy. Overall, by using both types of search keys, the total recall is increased.
