- Abstract
- Evaluates the performance of 8 major Internet search engines in answering 21 real reference questions and 5 made up subject questions. Reports on the retrieval and relevancy ranking abilities of the search engines. Concludes that the search engines did not produce good results for the reference questions unlike for the subject questions. The best engines are identified by type of questions, with Infoseek best for the subject questions, and OpenText best for refrence questions

- Abstract
- Das gezielte Suchen im Internet findet in erster Linie mit Hilfe der Suchmaschinen statt. Daneben gibt es aber bereits eine Fülle von strukturierten Informationsangeboten, aufbereiteten Listen und Sammelstellen, die als Clearinghouse, Subject Gateway, Subject Tree oder Resource Pages bezeichnet werden. Solche intellektuell erstellten Übersichten geben in der Regel bereits Hinweise zu Inhalt und fachlichem Niveau der Quelle. Da die Art und Weise der Aufbereitung bei den Sammelstellen sehr unterschiedlich funktioniert, ist die Kenntnis ihrer Erschließungskriterien für ein erfolgreiches Retrieval unverzichtbar

- Abstract
- The days of the traditional abstracting and indexing services are waning, as abstracts and bibliographic data become commodities. However, there are tremedous opportunities for those organizations willing to look beyond the status quo to the new possibilities enabled by the latest wave of advanced technologies. Those who own content need to focus on the delivery mechanisms and new markets that technology can provide. Features like automatic extraction of key concepts or names, collaborative filtering to help with trend analysis, and visualization techniques can take information past the retrieval stage and into the management area

- Abstract
- The increasing expansion of the Internet has made resources available to users in sometimes unmanageable abundance. To help users manage this proliferation of information, librarians have begun to add URLs to their home pages. As well, specialized search engines are being used to retrieve information from selected sources in aneffort to return pertinent results. Describes the Harvest system which has been used to develop Index Antiquus, a specialized engine, for the classics and mediaeval studies. Presents a working example of how to search Index Antiquus

- Abstract
- Selten wurde ein Dienst so stark diskutiert wie 'RealNames', da sowohl seine Suchwörter als auch die darauf aufsetzenden Links auf Homepages verkauft werden. Machen wir uns doch nichts vor: Das WWW ist ein kommerzielles Unternehmen, die Dienstleistungen müssen finanziert werden. Und warum soll nicht ein Privatunternehmen mit Inhaltserschließung Gewinne erzielen? RealNames mit seinem 'Internet Keyword System' ist eine interessante Idee, das Retrieval nach Homepages zielgenau durchzuführen. Was bringt RealNames den Nutzern? Wann sollte jemand, der Sites im WWW unterhält, Suchwörter und Links bei RealNames abonnieren (und was kostet das)? Im Oktober 1999 haben wir RealNames genauer angeschaut. Analysiert wurde das gezielte Retrieval nach Homepages bei AltaVista, Fireball und bei RealNames.com

- 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
- Describes a search engine that integrate text and image search. 1 or more Web site can be indexed for both textual and image information, allowing the user to search based on keywords or images or both. Another problem with the current search engines is that they show the results as pages of scrolled lists; this is not very user-friendly. The search engine allows the user to visualise to results in various ways. Explains the indexing and searching techniques of the search engine and highlights several features of the querying interface to make the retrieval process more efficient. Use examples to show the usefulness of the technology
