    Abstract
    Library of Congress Subject Headings (LCSH), a system originally designed as a tool for subject access to the Library's own collection in the late nineteenth century, has become, in the course of the last century, the main subject retrieval tool in library catalogs throughout the United States and in many other countries. It is one of the largest non-specialized controlled vocabularies in the world. As LCSH enters a new century, it faces an information environment that has undergone vast changes from what had prevailed when LCSH began, or, indeed, from its state in the early days of the online age. In order to continue its mission and to be useful in spheres outside library catalogs as well, LCSH must adapt to the multifarious environment. One possible approach is to adopt a series of scalable and flexible syntax and application rules to meet the needs of different user communities

    Abstract
    Library of Congress Subject Headings (LSCH), which celebrated its 100th birthday in 1998, is the largest cataloging and indexing language in the world for the indication of the topics and formats of books and similar publications. It consists of a controlled list of main headings, many with subdivisions, with a rich system of cross references. It is supported by the U.S. government, and undergoes systematic revision. In recent decades its managers have begun to confront challenges such as biased terminology, complicated syntax (how terms are put together to form headings), and effective displays in electronic media. Many suggestions have been made for its improvement, including moving to a fully faceted system.

    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
    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 discusses two inter-related themes: the retrieval potential of faceted thesauri and XML representations of fundamental facets. Initial findings are discussed from the ongoing 'FACET' project, in collaboration with the National Museum of Science and Industry. The work discussed seeks to take advantage of the structure afforded by faceted systems for multi-term queries and flexible matching, focusing in this paper an the Art and Architecture Thesaurus. A multi-term matching function yields ranked results with partial matches via semantic term expansion, based an a measure of distance over the semantic index space formed by thesaurus relationships. Our intention is to drive the system from general representations and a common query structure and interface. To this end, we are developing an XML representation based an work by the Classification Research Group an fundamental facets or categories. The XML representation maps categories to particular thesauri and hierarchies. The system interface, which is configured by the mapping, incorporates a thesaurus browser with navigation history together with a term search facility and drag and drop query builder.

    Abstract
    This article deals with the meaningful processing of information in relation to two systems of Information processing: pre-coordination and post-coordination. The different approaches are discussed, with emphasis an the need for a controlled vocabulary in information retrieval. Assigned indexing, which employs a controlled vocabulary, is described in detail. Types of indexing language can be divided into two broad groups - those using pre-coordinated terms and those depending an post-coordination. They represent two different basic approaches in processing and Information retrieval. The historical development of these two approaches is described, as well as the two tools that apply to these approaches: thesauri and subject headings.

    Abstract
    The paper looks at ways in which traditional classification and indexing tools have dealt with the relationships between constituent terms; variations in these are examined and compared with the methods used in machine searching, particularly of the Internet and World Wide Web. Apparent correspondences with features of index languages are identified, and further methods of applying classification and indexing theory to machine retrieval are proposed. There are various ways in which indexing and retrieval systems, both conventional and electronic, deal with the problem of searching for documents on a subject basis, and various approaches to the analysis and processing of a query. There appear to be three basic models; the taxonomic or structural system, in which the user is offered a map of the `universe of knowledge'; the language based system, which offers a vocabulary of the subject and a grammar for dealing with compound statements; and the mathematical model using the language of symbolic logic or the algebra of set theory

    Abstract
    The Subject Analysis Committee Subcommittee on FAST of the Association for Library Collections & Technical Services (ALCTS) was established in the fall of 2004 to explore issues related to the implementation of the Faceted Application of Subject Terminology (FAST) subject heading schema. FAST is being developed at the Online Computer Library Center (OCLC) and is derived from the Library of Congress Subject Headings (LCSH) with a simplified syntax. This paper is based on comments by the Subject Analysis Committee Subcommittee on FAST, which reviewed a sample of 5,000 bibliographic records with both LCSH and FAST headings. It provides the library community with some understanding of FAST, a new system of subject cataloging and metadata.

    Abstract
    After a fundamental examination of the phenomenon of time, this paper presents the history, authority, and structure of period subdivisions and chronological terms in the three subject heading languages LCSH (Library of Congress Subject Headings), RAMEAU (Répertoire d'Autorité Matière Encyclopédique et Alphabétique Unifié), and RSWK (Regeln für den Schlagwortkatalog). Their usefulness in online searching is demonstrated using the online catalogs of the Library of Congress, the Bibliothèque nationale de France, and the Deutsche Bibliothek and is compared to the search options in selected digital encyclopedias (Encyclopaedia Britannica, Encarta, Brockhaus-Enzyklopädie). The author develops a model for common time retrieval across all three online catalogs, outlines the conditions for that model (time period code, chronological code, and chronology authority file), and proposes a search interface.
