    Abstract
    International efforts to provide authority control include the work of IFLA, the AUTHOR Project funded by the European Commission, and related work conducted under the auspices of the ICA/CDS. IFLA developed the guidelines Form and Structure of Corporate Headings, documented the formulation of names along the lines of national origin in its publication Names of Persons, and published Guidelines for Authority and Reference Entries. Attention has shifted from a single authority record for each entity that would be shared internationally through the exchange of records to linking parallel authority records for the same entity. The access control of the future will account for difference in cataloging rules, transliteration standards, and cultural differences within the same language as well as for the need for different languages and scripts and will enable users to display the script and form of a heading that they expect. Project AUTHOR is a shared set of resource national authority files that used selections from the authority files of France, the United Kingdom, Spain, Portugal, and Belgium. The prototype tested an adaptation of Z39.50 server software for authority records and displays for user interface. An international standard for authority control records has been developed for corporate bodies, persons, and families. Through joint meetings efforts have been synchronized to develop authority control at the international level.

    Abstract
    What is the difference between Piaget's constructivism and Papert's "constructionism"? Beyond the mere play on the words, I think the distinction holds, and that integrating both views can enrich our understanding of how people learn and grow. Piaget's constructivism offers a window into what children are interested in, and able to achieve, at different stages of their development. The theory describes how children's ways of doing and thinking evolve over time, and under which circumstance children are more likely to let go of-or hold onto- their currently held views. Piaget suggests that children have very good reasons not to abandon their worldviews just because someone else, be it an expert, tells them they're wrong. Papert's constructionism, in contrast, focuses more on the art of learning, or 'learning to learn', and on the significance of making things in learning. Papert is interested in how learners engage in a conversation with [their own or other people's] artifacts, and how these conversations boost self-directed learning, and ultimately facilitate the construction of new knowledge. He stresses the importance of tools, media, and context in human development. Integrating both perspectives illuminates the processes by which individuals come to make sense of their experience, gradually optimizing their interactions with the world.

    Abstract
    Document representations for text classification are typically based on the classical Bag-Of-Words paradigm. This approach comes with deficiencies that motivate the integration of features on a higher semantic level than single words. In this paper we propose an enhancement of the classical document representation through concepts extracted from background knowledge. Boosting is used for actual classification. Experimental evaluations on two well known text corpora support our approach through consistent improvement of the results.

    Abstract
    Authority control is necessary for meeting the catalog's objectives of enabling users to find the works of an author and to collocate all works of a person or corporate body. This article looks at the current state of authority control as compared to the visions of the 1979 LITA (Library Information and Technology Association) Institutes and the 1984 Authority Control Interest Group. It explores a new view of IFLA's Universal Bibliographic Control (UBC) and a future vision of a virtual international authority file as a building block for the Semantic Web and reinforces the importance of authority control to improve the precision of searches of large databases or the Internet.

    Abstract
    The conceptual model known as "FRBR" (Functional Requirements for Bibliographic Records) reminds us of the basic elements in describing materials in the bibliographic universe, the inter-relationships, and the fundamental user tasks that we are trying to address when we create library catalogs. This model provides a new perspective on cataloging that should influence the design of future systems, cataloging codes, and cataloging practices. This paper explores current activities to utilize the FRBR model within cataloging principles, cataloging codes, and cataloging systems, and offers questions, visions, and suggests some next steps.

    Abstract
    The advantages of unique identifiers for the entities described in authority records are outweighed by the costs to manage an international system for assigning and maintaining such unique identifiers. Today's and tomorrow's systems perhaps can do without unique identifiers, but the attraction of unique identifiers still persists. This paper provides a personal recommendation to use the existing machine-generated record control numbers from our authority records as an interim measure until we see what future systems need.

    Abstract
    Purpose - The purpose of this paper is to summarize the varied structural characteristics which may be present in retrieval languages. Design/methodology/approach - The languages serve varied purposes in information systems, and a number of these are identified. The relations between structure and function are discussed and suggestions made as to the most suitable structures needed for various purposes. Findings - A quantitative approach has been developed: a simple measure is the number of separate terms in a retrieval language, but this has to be related to the scope of its subject field. Some ratio of terms to items in the field seems a more suitable measure of the average specificity of the terms. Other aspects can be quantified - for example, the average number of links in hierarchical chains, or the average number of cross-references in a thesaurus. Originality/value - All the approaches to the analysis of retrieval language reported in this paper are of continuing value. Some practical studies of computer information systems undertaken by Aslib Research Department have suggested a further approach.

    Abstract
    Contributions of DRTC to informetric studies and research are discussed. A report on recent work - a quantitative country-wise analysis of software literature based on the data from two bibliographic databases i.e. COMPENDEX and INSPEC is presented. The number of countries involved in R & D activities in software in the most productive group is increasing. The research contribution on software is decreasing in developed countries as compared to that in developing and less developed countries. India 's contribution is only 1.1% and it has remained constant over the period of 12 years 1989-2001. The number of countries involved in R&D activities in software has been increasing in the 1990s. It is also noted that higher the budget for higher education, higher the number of publications; and that higher the number of publications, higher the export as well as the domestic consumption of software.

    Abstract
    The focus of this paper is to investigate the possibility of predicting several user and message attributes in text-based, real-time, online messaging services. For this purpose, a large collection of chat messages is examined. The applicability of various supervised classification techniques for extracting information from the chat messages is evaluated. Two competing models are used for defining the chat mining problem. A term-based approach is used to investigate the user and message attributes in the context of vocabulary use while a style-based approach is used to examine the chat messages according to the variations in the authors' writing styles. Among 100 authors, the identity of an author is correctly predicted with 99.7% accuracy. Moreover, the reverse problem is exploited, and the effect of author attributes on computer-mediated communications is discussed.

    Abstract
    Explores the opportunities for libraries to contribute to the proposed global "Semantic Web." Library name and subject authority files, including work that IFLA has done related to a new view of "Universal Bibliographic Control" in the Internet environment and the work underway in the U.S. and Europe, are making a reality of the virtual international authority file on the Web. The bibliographic and authority records created according to AACR2 reflect standards for metadata that libraries have provided for years. New opportunities for using these records in the digital world are described (interoperability), including mapping with Dublin Core metadata. AACR2 recently updated Chapter 9 on Electronic Resources. That process and highlights of the changes are described, including Library of Congress' rule interpretations.
