    Abstract
    Conceptual Knowledge Markup Language (CKML), an application of XML, is a new standard being promoted for the specification of online conceptual knowledge (Kent and Shrivastava, 1998). CKML follows the philosophy of Conceptual Knowledge Processing (Wille, 1982), a principled approach to knowledge representation and data analysis, which advocates the development of methodologies and techniques to support people in their rational thinking, judgement and actions. CKML was developed and is being used in the WAVE networked information discovery and retrieval system (Kent and Neuss, 1994) as a standard for the specification of conceptual knowledge

    Abstract
    The knowledge structures that form traditional library classification schemes hold great potential for improving resource description and discovery on the Internet and for organizing electronic document collections. The advantages of assigning subject tokens (classes) to documents from a scheme like the DDC system are well documented

    Abstract
    Creates an open, metadata aware system for distributed, collaborative WWW indexing. The system has 3 main components: a harvester (for collecting information), a database (for making the collection searchable), and a user interface (for making the information available). all components can be distributed across networked computers, thus supporting scalability. The system is metadata aware and thus allows searches on several fields including title, document author and URL. Nordic Web Index (NWI) is an application using this system to create a regional Nordic Web-indexing service. NWI is built using 5 collaborating service points within the Nordic countries. The NWI databases can be used to build additional services

    Abstract
    Argues that classification systems have an important role to play in knowledge organization in the new world electronic order. The natural language approach is not incompatible with the use of a classification system and classification has untapped potential as a multilingual switching language. Librarians must learn to present classification systems in a language understood by a general audience and promote them as general knowledge organization tools

    Abstract
    Organizing and providing access to the resources an the Internet has been a problem area in spite of the availability of sophisticated search engines and other Software tools. There have been several attempts to organize the resources an the World Wide Web. Some of them have tried to use traditional library classification schemes such as the Library of Congress Classification, the Dewey Decimal Classification and others. However there is a need to assign proper subject headings to them and present them in a logical or hierarchical sequence to cater to the need for browsing. This paper attempts to describe an experimental system designed to organize and provide access to web documents using a faceted pre-coordinate indexing system based an the Deep Structure Indexing System (DSIS) derived from POPSI (Postulate based Permuted Subject Indexing) of Bhattacharyya, and the facet analysis and chain indexing system of Ranganathan. A prototype Software System has been designed to create a database of records specifying Web documents according to the Dublin Core and to input a faceted subject heading according to DSIS. Synonymous terms are added to the Standard terms in the heading using appropriate symbols. Once the data are entered along with a description and the URL of the web document, the record is stored in the System. More than one faceted subject heading can be assigned to a record depending an the content of the original document. The System stores the Surrogates and keeps the faceted subject headings separately after establishing a link. The search is carried out an index entries derived from the faceted subject heading using the chain indexing technique. If a single term is Input, the System searches for its presence in the faceted subject headings and displays the subject headings in a sorted sequence reflecting an organizing sequence. If the number of retrieved Keadings is too large (running into more than a page) the user has the option of entering another search term to be searched in combination. The System searches subject headings already retrieved and looks for those containing the second term. The retrieved faceted subject headings can be displayed and browsed. When the relevant subject heading is selected the system displays the records with their URLs. Using the URL, the original document an the web can be accessed. The prototype system developed in a Windows NT environment using ASP and a web server is under rigorous testing. The database and Index management routines need further development.
    An interesting but somewhat confusing article telling how the writers described web pages with Dublin Core metadata, including a faceted classification, and built a system that lets users browse the collection through the facets. They seem to want to cover too much in a short article, and unnecessary space is given over to screen shots showing how Dublin Core metadata was entered. The screen shots of the resulting browsable system are, unfortunately, not as enlightening as one would hope, and there is no discussion of how the system was actually written or the technology behind it. Still, it could be worth reading as an example of such a system and how it is treated in journals.

    Abstract
    This paper aims to explore the changes in the role of classification and the opportunities presented for classification in the twenty-first century, especially in respect to the development of information technology. The issues arose as part of the EC funded MIRACLE project that represents the foundation for a virtual music library to serve visually impaired people. The MIRACLE partners chose the UDC as the common classification for the converging music catalogues. This paper investigates the nature of adaptation required by each participating library and the way in which the classification is used as a searching tool. Further developments in the use of IT-assisted classification are proposed

    Abstract
    Basic skills of classification and subject indexing have been little taught in British library schools since automation was introduced into libraries. However, development of the Internet as a major medium of publication has stretched the capability of search engines to cope with retrieval. Consequently, there has been interest in applying existing systems of knowledge organization to electronic resources. Unfortunately, the classification systems have been adopted without a full understanding of modern classification principles. Analytico-synthetic schemes have been used crudely, as in the case of the Universal Decimal Classification (UDC). The fully faceted Bliss Bibliographical Classification, 2nd edition (BC2) with its potential as a tool for electronic resource retrieval is virtually unknown outside academic libraries
    Content
    A short discussion of using classification systems to organize the web, one of many such. The authors are both involved with BC2 and naturally think it is the best system for organizing information online. They list reasons why faceted classifications are best (e.g. no theoretical limits to specificity or exhaustivity; easier to handle complex subjects; flexible enough to accommodate different user needs) and take a brief look at how BC2 works. They conclude with a discussion of how and why it should be applied to online resources, and a plea for recognition of the importance of classification and subject analysis skills, even when full-text searching is available and databases respond instantly.

    Abstract
    Developments in electronic communication technology have meda online databases a normal part of library collections. To provide users with direct access to Internet resources the Dutch Royal Library has cooperated with several university libraries in the Netherlands to develop the Nederlandse Basisclassificatie Web. Subject specialists select sources, add English summaries and NBW code, and input them to the online database. A Web desk and training workshops have been provided to assist users, and improvements to the system will simplify search procedures

    Abstract
    For generations, libraries have facilitated access to information sources by the development and use of a wide range of appropriate organizational processes. Within a Web-based demonstration prototype, we have applied several established library procedures, principles and practices to enhance access to selected Internet resources in science and technology. In seeking to manage these sources, we have established defined collection, adopted an established library classification scheme as an organizational framework, and sought to stimulate the features and functions of a physical library collection and conventional reference sourcees. This paper describes the key components of this prototype, reviews research which supports its approach, and profiles suggested enhancements which could further facilitate identification, access and use of significant Internet and WWW resources

    Abstract
    Different forms of indexing and search facilities available on the Web are described. Use of facet analysis to structure hypertext concept structures is outlined in relation to work on (1) development of hypertext knowledge bases for designers of learning materials and (2) construction of knowledge based hypertext interfaces. The problem of lack of closeness between page designers and potential users is examined. Facet analysis is suggested as a way of alleviating some difficulties associated with this problem of designing for the unknown user.
    This is a revised version of the earlier article by Ellis and Vasconcelos (1999) (see Not Relevant, below), though that is not indicated, and much of it is identical, word for word. There is a new section covering the work of Elizabeth Duncan, which is useful and informative, but the reader is better advised to go to the originals if available.

    Abstract
    In the present work we discuss opportunities, problems, tools and techniques encountered when interconnecting discipline-specific subject classifications, primarily organized as search devices in bibliographic databases, with general classifications originally devised for book shelving in public libraries. We first state the fundamental distinction between topical (or subject) classifications and object classifications. Then we trace the structural limitations that have constrained subject classifications since their library origins, and the devices that were used to overcome the gap with genuine knowledge representation. After recalling some general notions on structure, dynamics and interferences of subject classifications and of the objects they refer to, we sketch a synthetic overview on discipline-specific classifications in Mathematics, Computing and Physics, on one hand, and on general classifications on the other. In this setting we present The Scientific Classifications Page, which collects groups of Web pages produced by a pool of software tools for developing hypertextual presentations of single or paired subject classifications from sequential source files, as well as facilities for gathering information from KWIC lists of classification descriptions. Further we propose a concept-oriented methodology for interconnecting subject classifications, with the concrete support of a relational analysis of the whole Mathematics Subject Classification through its evolution since 1959. Finally, we recall a very basic method for interconnection provided by coreference in bibliographic records among index elements from different systems, and point out the advantages of establishing the conditions of a more widespread application of such a method. A part of these contents was presented under the title Mathematics Subject Classification and related Classifications in the Digital World at the Eighth International Conference Crimea 2001, "Libraries and Associations in the Transient World: New Technologies and New Forms of Cooperation", Sudak, Ukraine, June 9-17, 2001, in a special session on electronic libraries, electronic publishing and electronic information in science chaired by Bernd Wegner, Editor-in-Chief of Zentralblatt MATH.

    Abstract
    Ia McIlwaine, head of the Classification Research Group and editor of the UDC, noticed that the session's title invited crystal ball gazing, a talent she denied possessing. However, she admitted that she had asked the Classification Research Group to engage in such an exercise with her. The Group found, like the participants at the Allerton Institute were finding, that the contemplation of classification's future provided more questions than answers, but the questions were well worth considering. Her talk focused around a problem which originates in the difference between classifiers' uses and users' uses for classification systems. For users, who speak with the paraphrased self-confidence of Humpty Dumpty, a subject is a subject because they say it is. McIlwaine pointed out that this process of "saying" is at the heart of the users' needs which should be addressed by classification systems. Users use words to approach information systems and their associated classification systems. Classifiers need to recognize that this is the use to which their systems will be put. A body of users external to the classification process will make very different demands upon the system as compared to the users of the classification system who are also the creators of the system. Users desire information grouped for individual usefulness, and the groupings need to be according to words through which users can approach the system.
