- 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
- Describes the shortcomings of search engines for the WWW comparing their current capabilities to those of the first generation CD-ROM products. Some allow phrase searching and most are improving their Boolean searching. Few allow truncation, wild cards or nested logic. They are stateless, losing previous search criteria. Unlike the indexing and classification systems for today's CD-ROMs, those for Web pages are random, unstructured and of variable quality. Considers that at best Web search engines can only offer free text searching. Discusses whether automatic data classification systems such as Infoseek Ultra can overcome the haphazard nature of the Web with neural network technology, and whether Boolean search techniques may be redundant when replaced by technology such as the Euroferret search engine. However, artificial intelligence is rarely successful on huge, varied databases. Relevance ranking and automatic query expansion still use the same simple inverted indexes. Most Web search engines do nothing more than word counting. Further complications arise with foreign languages

- 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
- Eine ganze Anzahl von Bibliotheken in Europa befaßt sich mit der Entwicklung von Internet Subject Gateways - einer Serviceleistung, die den Nutzern helfen soll, qualitativ hochwertige Internetquellen zu finden. Subject Gateways wie SOSIG (The Social Science Information Gateway) sind bereits seit einigen Jahren im Internet verfügbar und stellen eine Alternative zu Internet-Suchmaschinen wie AltaVista und Verzeichnissen wie Yahoo dar. Bezeichnenderweise stützen sich Subject Gateways auf die Fertigkeiten, Verfahrensweisen und Standards der internationalen Bibliothekswelt und wenden diese auf Informationen aus dem Internet an. Dieses Referat will daher betonen, daß Bibliothekare/innen idealerweise eine vorherrschende Rolle im Aufbau von Suchservices für Internetquellen spielen und daß Information Gateways eine Möglichkeit dafür darstellen. Es wird einige der Subject Gateway-Initiativen in Europa umreißen und die Werkzeuge und Technologien beschreiben, die vom Projekt DESIRE entwickelt wurden, um die Entwicklung neuer Gateways in anderen Ländern zu unterstützen. Es wird auch erörtert, wie IMesh, eine Gruppe für Gateways aus der ganzen Welt eine internationale Strategie für Gateways anstrebt und versucht, Standards zur Umsetzung dieses Projekts zu entwickeln

- Abstract
- The purpose of this paper is to determine some of the structural features of the classification schemes used in the directories (guides, channels) of search engines to organise information sources on the Internet. Ten search engines were examined at the main class level and the full hierarchies of a sample of three specific subjects were analysed in four of these engines, namely Excite, Infoseek, Lycos and Yahoo! It was found that there are major differences between the main classes of the search engines and those found in standard library schemes like Dewey, UDC and LCC. There are large gaps in subject coverage at main class level in the search engines and the general tendency is to use a topic-based approach in the formation of classes, rather than a discipline-based approach. The subdivision of the main classes is according to hierarchical tree structures, but a number of anomalies in this regard were identified. Another deviation from library classification theory is that various principles of division are employed to form classes at the same hierarchical level. In an analysis of citation orders many examples were found that conform to the principles followed in library classifications, but a number of inconsistencies in this regard were also noted

- 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
