    AHUJA and SATIJA (Relevance of Ranganathan's Classification Theory in the Age of Digital Libraries) note that traditional bibliographic classification systems have been applied in the digital environment with only limited success. They find that the "inherent flexibility of electronic manipulation of documents or their surrogates should allow a more organic approach to allocation of new subjects and appropriate linkages between subject hierarchies." (p. 18). Ahija and Satija also suggest that it is necessary to shift from a "subject" focus to a "need" focus when applying classification theory in the digital environment. They find Ranganathan's framework applicable in the digital environment. Although Ranganathan's focus is "subject oriented and hence emphasise the hierarchical and linear relationships" (p. 26), his framework "can be successfully adopted with certain modifications ... in the digital environment." (p. 26). SHAH and KUMAR (Model for System Unification of Geographical Schedules (Space Isolates)) report an a plan to develop a single schedule for geographical Subdivision that could be used across all classification systems. The authors argue that this is needed in order to facilitate interoperability in the digital environment. SAN SEGUNDO MANUEL (The Representation of Knowledge as a Symbolization of Productive Electronic Information) distills different approaches and definitions of the term "representation" as it relates to representation of knowledge in the library and information science literature and field. SHARADA (Linguistic and Document Classification: Paradigmatic Merger Possibilities) suggests the development of a universal indexing language. The foundation for the universal indexing language is Chomsky's Minimalist Program and Ranganathan's analytico-synthetic classification theory; Acording to the author, based an these approaches, it "should not be a problem" (p. 62) to develop a universal indexing language.
    SELVI (Knowledge Classification of Digital Information Materials with Special Reference to Clustering Technique) finds that it is essential to classify digital material since the amount of material that is becoming available is growing. Selvi suggests using automated classification to "group together those digital information materials or documents that are "most similar" (p. 65). This can be attained by using Cluster analysis methods. PRADHAN and THULASI (A Study of the Use of Classification and Indexing Systems by Web Resource Directories) compare and contrast the classificatory structures of Google, Yahoo, and Looksmart's directories and compare the directories to Dewey Decimal Classification, Library of Congress Classification and Colon Classification's classificatory structures. They find differentes between the directories' and the bibliographic classification systems' classificatory structures and principles. These differentes stem from the fact that bibliographic classification systems are used to "classify academic resources for the research community" (p. 83) and directories "aim to categorize a wider breath of information groups, entertainment, recreation, govt. information, commercial information" (p. 83). NEELAMEGHAN (Hierarchy, Hierarchical Relation and Hierarchical Arrangement) reviews the concept of hierarchy and the formation of hierarchical structures across a variety of domains. NEELAMEGHAN and PRADAD (Digitized Schemes for Subject Classification and Thesauri: Complementary Roles) demonstrate how thesaural relationships (NT, BT, and RT) can be applied to a classification scheme, the Colon Classification in this Gase. NEELAMEGHAN and ASUNDI (Metadata Framework for Describing Embodied Knowledge and Subject Content) propose to use the Generalized Facet Structure framework which is based an Ranganathan's General Theory of Knowledge Classification as a framework for describing the content of documents in a metadata element set for the representation of web documents. CHUDAMANI (Classified Catalogue as a Tool for Subject Based Information Retrieval in both Traditional and Electronic Library Environment) explains why the classified catalogue is superior to the alphabetic cata logue and argues that the same is true in the digital environment.
    PARAMESWARAN (Classification and Indexing: Impact of Classification Theory an PRECIS) reviews the PRECIS system and finds that "it Gould not escape from the impact of the theory of classification" (p. 131). The author further argues that the purpose of classification and subject indexing is the same and that both approaches depends an syntax. This leads to the conclusion that "there is an absolute syntax as the Indian theory of classification points out" (p. 131). SATYAPAL and SANJIVINI SATYAPAL (Classifying Documents According to Postulational Approach: 1. SA TSAN- A Computer Based Learning Package) and SATYAPAL and SANJIVINI SATYAPAL (Classifying Documents According to Postulational Approach: 2. Semi-Automatic Synthesis of CC Numbers) present an application to automate classification using a facet classification system, in this Gase, the Colon Classification system. GAIKAIWARI (An Interactive Application for Faceted Classification Systems) presents an application, called SRR, for managing and using a faceted classification scheme in a digital environment. IYER (Use of Instructional Technology to Support Traditional Classroom Learning: A Case Study) describes a course an "Information and Knowledge Organization" that she teaches at the University at Albany (SUNY). The course is a conceptual course that introduces the student to various aspects of knowledge organization. GOPINATH (Universal Classification: How can it be used?) lists fifteen uses of universal classifications and discusses the entities of a number of disciplines. GOPINATH (Knowledge Classification: The Theory of Classification) briefly reviews the foundations for research in automatic classification, summarizes the history of classification, and places Ranganathan's thought in the history of classification.

    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 WWW. 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 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 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. Search is carried out an index entries derived from the faceted subject heading using 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 headings is too large (running into more than a page) then the user has the option of entering another search term to be searched in combination. The system searches subject headings already retrieved and look 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 under Windows NT environment using ASP and web server is under rigorous testing. The database and indexes management routines need further development.

    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

    Abstract
    The paper gives a short overview of the history of use of UDC in Internet subject gateways (SGs) with an English interface, from 1993 to 2006. There were in total, nine quality controlled SGs that were functional for shorter or longer periods of time. Their typology and functionality is described. Quality SGs have evolved and the role of classification has changed accordingly from supporting subject organization on the interface and automatic categorization of resources, towards supporting a semantic linking, control and vocabulary mapping between different indexing systems in subject hubs and federated SGs. In this period, many SGs ceased to exist and little information remains available regarding their status. SGs currently using UDC, for some part of their resource organization, do not use a UDC subject hierarchy at the interface and its role in resource indexing has become more difficult to observe. Since 2000, UDC has become more prevalent in East European SGs, portals and hubs, which are outside the scope of this research. This paper is an attempt to provide a record on this particular application of UDC and to offer some consideration of the changes in requirements when it comes to the use of library classification in resource discovery.

    1. Introduction Web search engines and digital libraries usually expect the users to use search terms that most accurately represent their information needs. Finding the most appropriate search terms to represent an information need is an age old problem in information retrieval. Keyword or phrase search may produce good search results as long as the search terms or phrase(s) match those used by the authors and have been chosen for indexing by the concerned information retrieval system. Since this does not always happen, a large number of false drops are produced by information retrieval systems. The retrieval results become worse in very large systems that deal with millions of records, such as the Web search engines and digital libraries. Vocabulary control tools are used to improve the performance of text retrieval systems. Thesauri, the most common type of vocabulary control tool used in information retrieval, appeared in the late fifties, designed for use with the emerging post-coordinate indexing systems of that time. They are used to exert terminology control in indexing, and to aid in searching by allowing the searcher to select appropriate search terms. A large volume of literature exists describing the design features, and experiments with the use, of thesauri in various types of information retrieval systems (see for example, Furnas et.al., 1987; Bates, 1986, 1998; Milstead, 1997, and Shiri et al., 2002).

    Abstract
    This is a preprint to be published in the Extensions & Corrections to the UDC. The paper explains the basic functions of browsing and searching that need to be supported in relation to analytico-synthetic classifications such as Universal Decimal Classification (UDC), irrespective of any specific, real-life implementation. UDC is an example of a semi-faceted system that can be used, for instance, for both post-coordinate searching and hierarchical/facet browsing. The advantages of using a classification for IR, however, depend on the strength of the GUI, which should provide a user-friendly interface to classification browsing and searching. The power of this interface is in supporting visualisation that will 'convert' what is potentially a user-unfriendly indexing language based on symbols, to a subject presentation that is easy to understand, search and navigate. A summary of the basic functions of searching and browsing a classification that may be provided on a user-friendly interface is given and examples of classification browsing interfaces are provided.

    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.

    Abstract
    Ab Januar 2006 wird Die Deutsche Bibliothek ein neues Webangebot mit dem Namen Melvil starten, das ein Ergebnis ihres Engagements für die DDC und das Projekt DDC Deutsch ist. Der angebotene Webservice basiert auf der Übersetzung der 22. Ausgabe der DDC, die im Oktober 2005 als Druckausgabe im K. G. Saur Verlag erscheint. Er bietet jedoch darüber hinausgehende Features, die den Klassifizierer bei seiner Arbeit unterstützen und erstmals eine verbale Recherche für Endnutzer über DDCerschlossene Titel ermöglichen. Der Webservice Melvil gliedert sich in drei Anwendungen: - MelvilClass, - MelvilSearch und - MelvilSoap.

    Abstract
    Purpose - This paper aims to provide an overview of principles and procedures involved in creating a faceted classification scheme for use in resource discovery in an online environment. Design/methodology/approach - Facet analysis provides an established rigorous methodology for the conceptual organization of a subject field, and the structuring of an associated classification or controlled vocabulary. This paper explains how that methodology was applied to the humanities in the FATKS project, where the objective was to explore the potential of facet analytical theory for creating a controlled vocabulary for the humanities, and to establish the requirements of a faceted classification appropriate to an online environment. A detailed faceted vocabulary was developed for two areas of the humanities within a broader facet framework for the whole of knowledge. Research issues included how to create a data model which made the faceted structure explicit and machine-readable and provided for its further development and use. Findings - In order to support easy facet combination in indexing, and facet searching and browsing on the interface, faceted classification requires a formalized data structure and an appropriate tool for its management. The conceptual framework of a faceted system proper can be applied satisfactorily to humanities, and fully integrated within a vocabulary management system. Research limitations/implications - The procedures described in this paper are concerned only with the structuring of the classification, and do not extend to indexing, retrieval and application issues. Practical implications - Many stakeholders in the domain of resource discovery consider developing their own classification system and supporting tools. The methods described in this paper may clarify the process of building a faceted classification and may provide some useful ideas with respect to the vocabulary maintenance tool. Originality/value - As far as the authors are aware there is no comparable research in this area.
