Abstract

The Wolverhampton Web Library (WWLib) is a WWW search engine that provides access to UK based information. The experimental version developed in 1995, was a success but highlighted the need for a much higher degree of automation. An interesting feature of the experimental WWLib was that it organised information according to DDC. Discusses the advantages of classification and describes the automatic classifier that is being developed in Java as part of the new, fully automated WWLib

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

Am 29. und 30. Oktober 2009 fand in der Königlichen Bibliothek in Den Haag das zweite internationale UDC-Seminar zum Thema "Classification at a Crossroad" statt. Organisiert wurde diese Konferenz - wie auch die erste Konferenz dieser Art im Jahr 2007 - vom UDC-Konsortium (UDCC). Im Mittelpunkt der diesjährigen Veranstaltung stand die Erschließung des World Wide Web unter besserer Nutzung von Klassifikationen (im Besonderen natürlich der UDC), einschließlich benutzerfreundlicher Repräsentationen von Informationen und Wissen. Standards, neue Technologien und Dienste, semantische Suche und der multilinguale Zugriff spielten ebenfalls eine Rolle. 135 Teilnehmer aus 35 Ländern waren dazu nach Den Haag gekommen. Das Programm umfasste mit 22 Vorträgen aus 14 verschiedenen Ländern eine breite Palette, wobei Großbritannien mit fünf Beiträgen am stärksten vertreten war. Die Tagesschwerpunkte wurden an beiden Konferenztagen durch die Eröffnungsvorträge gesetzt, die dann in insgesamt sechs thematischen Sitzungen weiter vertieft wurden.

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

The paper examines the potentiality of the Universal Decimal Classification as a means for retrieving subjects from the World Wide Web. The analytico-synthetic basis of the scheme provides the facility to link concepts at the input or search stage and to isolate concepts via the notation so as to retrieve the separate parts of a compound subject individually if required. Its notation permits hierarchical searching and overrides the shortcomings of natural language. Recent revisions have been constructed with this purpose in mind, the most recent being for Management. The use of the classification embedded in metadata, as in the GERHARD system or as a basis for subject trees is discussed. Its application as a gazetteer is another Web application to which it is put. The range of up to date editions in many languages and the availability of a Web-based version make its use as a switching language increasingly valuable.

Abstract

The explosion of the use of the Internet by the genral public, particularly via the WWW, has given rise to the proliferation of semiprofessional attempts to give some subject based access to Internet resources via hierarchical guides (hotlists) on Web search engines such as Yahoo and Magellan. Examines the structure and principles of various hierachical lists, and compares them, when possible, to broad LCC and DDC schemes, and to LCSH. Explores the approaches taken by non librarians in their efforts to organize and provide access to materials on the Internet. Focuses on the dichotomy between the hierarchical 'browse' and the analytical 'search' approaches to finding materials, as exemplified by these various attempts to organize the Internet

Abstract

Die intellektuelle Erschließung des Internet befindet sich in einer Krise. Yahoo und andere Dienste können mit dem Wachstum des Web nicht mithalten. GERHARD ist derzeit weltweit der einzige Such- und Navigationsdienst, der die mit einem Roboter gesammelten Internetressourcen mit computerlinguistischen und statistischen Verfahren auch automatisch vollständig klassifiziert. Weit über eine Million HTML-Dokumente von wissenschaftlich relevanten Servern in Deutschland können wie bei anderen Suchmaschinen in der Datenbank gesucht, aber auch über die Navigation in der dreisprachigen Universalen Dezimalklassifikation (ETH-Bibliothek Zürich) recherchiert werden

Abstract

This article gives a cheerfully brief and undetailed account of how to make a faceted classification system, then describes information retrieval and searching on the web. It concludes by saying that facets would be excellent in helping users search and browse the web, but offers no real clues as to how this can be done.

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

"Online retrieval" conjures up a very different mental image now than in 1991, the year this article was written, and the year Tim Berners-Lee first revealed the new hypertext system he called the World Wide Web. Gödert shows that truncation and Boolean logic, combined with notation from a faceted classification system, will be a powerful way of searching for information. It undoubtedly is, but no system built now would require a user searching for material on "nervous systems of bone fish" to enter "Fdd$ and Leaa$". This is worth reading for someone interested in seeing how searching and facets can go together, but the web has made this article quite out of date.

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 presents a study conducted at the University of Colorado at Boulder (CU-Boulder) to assess the extent to which its catalogers were using Classification Web (Class Web), the subscription-based, online cataloging documentation resource provided by the Library of Congress. In addition, this paper will explore assumptions made by management regarding CU-Boulder catalogers' use of the product, possible reasons for the lower-than-expected use, and recommendations for promoting a more efficient and cost-effective use of Class Web at other institutions similar to CU-Boulder.

Abstract

This is a report on how Doyle and others made a faceted classification scheme for content management systems and made it browsable on the web (see CMS Review in Example Web Sites, below). They discuss why they did it, how, their use of OPML and XFML, how they did research to find terms and categories, and they also include their taxonomy. It is interesting to see facets used in a business environment.

Abstract

A fascinating, broad-ranging article about classification, knowledge, and how they relate. Hierarchies, trees, paradigms (a two-dimensional classification that can look something like a spreadsheet), and facets are covered, with descriptions of how they work and how they can be used for knowledge discovery and creation. Kwasnick outlines how to make a faceted classification: choose facets, develop facets, analyze entities using the facets, and make a citation order. Facets are useful for many reasons: they do not require complete knowledge of the entire body of material; they are hospitable, flexible, and expressive; they do not require a rigid background theory; they can mix theoretical structures and models; and they allow users to view things from many perspectives. Facets do have faults: it can be hard to pick the right ones; it is hard to show relations between them; and it is difficult to visualize them. The coverage of the other methods is equally thorough and there is much to consider for anyone putting a classification on the web.

Abstract

Two library classification system interfaces have been implemented for navigating and searching large collections of document and book records. One interface allows the user to browse book records organized by the DDC hierarchy. A Book Shelf display reflects the facet position in the classification hierarchy during browsing, and it dynamically updates to reflect search hits and attribute selections. The other interface provides access to records describing computer science documents classified by the ACM Computing Reviews (CR) system. The CR classification system is a type of faceted classification in which documents can appear at several points in the hierarchy. These two interfaces demonstrate that classification structure can be effectively utilized for organizing digital libraries and, potentiall, collections of Internet-wide information services

Abstract

This paper presents the results of a survey examining the extent to which working catalogers use Classification Web, the Library of Congress' online resource for subject heading and classification documentation. An earlier survey analyzed Class Web's usefulness on an institutional level. This broader survey expands on that analysis and provides information on such questions as: what types of institutions subscribe to Class Web; what are the reasons for using Class Web when performing original or copy cataloging; and what other resources do catalogers use for classification/subject heading analysis?
