- 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
- This paper is about search of photos in photo databases of agencies which sell photos over the Internet. The problem is far from the behavior of photo databases managed by librarians and also far from the corpora generally used for research purposes. The descriptions use mainly single words and it is well known that it is not the best way to have a good search. This increases the problem of semantic ambiguity. This problem of semantic ambiguity is crucial for cross-language querying. On the other hand, users are not aware of documentation techniques and use generally very simple queries but want to get precise answers. This paper gives the experience gained in a 3 year use (2006-2008) of a cross-language access to several of the main international commercial photo databases. The languages used were French, English, and German.

- 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

- "Die Betreiber der populärsten Internet-Suchmaschine Google planen nach amerikanischen Presseberichten die Digitalisierung von mehr als 15 Millionen Büchern. Das Unternehmen habe eine Vereinbarung mit renommierten Universitätsbibliotheken geschlossen und wollte das Projekt noch am Dienstag offiziell vorstellen, berichtete die "NewYorkTimes". Beteiligt seien unter anderem die Universitäten von Harvard, Stanford und Oxford. Nach dem Bericht der Zeitung könnte das Projekt mehr als zehn Jahre Arbeit in Anspruch nehmen. Die Digitalisierung koste rund zehn Dollar pro Buch. Insgesamt umfasse die Vereinbarung 15 Millionen Bücher, darunter die ganzen Bestände der Universitäten von Stanford und Michigan sowie ausgewählte Werke aus Harvard und der Bodleian-Bibliothek in Oxford sowie der öffentlichen Bücherei von New York. Werke aus den Sammlungen dieser Hochschulen sollten digitalisiert werden, sodass Internet-Surfer via Google nach ihnen suchen könnten, kündigte Google-Mitbegründer Larry Page an. Über das Programm solle auch nach Titeln gesucht werden können, die nicht zu kaufen seien, sondern allein in Bibliotheksregalen stünden. Das neue Projekt geht über ein bereits vorhandenes Google-Angebot hinaus, mit dem Internet-Nutzer Inhalte aus Neuveröffentlichungen suchen können. Page sagte schon vor der Gründung von Google habe er davon geträumt, die Fülle von Informationen aus Bibliotheken ins Netz zu stellen. Nur Bücher, die nicht mehr durch Copyright geschützt sind, sollen in voller Länge in die virtuelle Bibliothek aufgenommen werden. Aus jüngeren Werken sollen nur Auszüge veröffentlicht werden. Google will die Bücher mit seinen regulären Web-Services zugänglich machen. Die beteiligten Bibliotheken erhalten im Gegenzug eine digitale Datenbasis, die ihre eigenen Werke enthält und die die Universitäten auf ihren eigenen Websites zur Verfügung stellen.

- Abstract
- Die Bewertung von Internet-Dokumenten nach ihrer Qualität wird im Zeitalter verteilten und in großen Mengen vorliegenden Wissens zunehmend an Software delegiert. Dies gilt besonders bei der Suche nach Informationen etwa mit Internet-Suchmaschinen, bei der Qualitätsbewertungssysteme als Filter einsetzbar sind. Die starke Heterogenität der Qua-lität von Internet-Dokumenten lässt hier einen besonderen Mehrwert erwarten. Experimentelle Systeme behandeln verschiedeneAspekte und nutzen unterschiedliche Definitionen von Oualität. Im Einsatz befindliche Systeme greifen zur Zeit auf einzelne und begrenzte Aspekte von Qualität zu. Insbesondere die Analyse der Verlinkungsstruktur des Internets bietet einen Ansatzpunkt für existierende Systeme. Die Komplexität des Qualitätskonzepts und der Dokumente erfordert jedoch auf mehreren Aspekten beruhende Definitionen. Im Projekt AQUAINT (Automatische Qualitätsabschätzung für Internet Ressourcen) werden Oualitätsdefinitionen aus menschlichen Urteilen abgeleitet. Formale Eigenschaften von Internet-Seiten werden automatisch extrahiert. Menschliche Oualitätsurteile unterschiedlichster Art bilden die Grundlage für Verfahren des maschinellen Lernens. So entstehen Klassifikationssysteme, welche die menschlichen Urteile so weit wie möglich simulieren. Diese werden in prototypischen Such- und Filtersystemen integriert.

- Abstract
- Provides a glossary of Internet search terms. Outlines a number of network retrieval tools and directories: Netscape's Internet search page, W3 search engines, Lycos, WebCrawler, InfoSeek, Yahoo, and CERN's Net Directory. Gices an example of how the Internet can be used to answer a reference query and the types of materials that can be retrieved

- 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

- Abstract
- Search engines are defined, and recent developments described, exemplified, and evaluated, especially those concerned with traditional search and retrieval capabilities. Discussion concentrates on two broad issues: (1) collection and indexing methods and (2) retrieval and ranking methods. It is concluded that a wider adoption of field searching, proximity searching, and relevance feedback would improve quality of search results

- Abstract
- Die Datenmenge im WWW, welche in Form von Internet-Seiten über URLs zugänglich ist, wächst derzeit stark an. Um aus dieser Menge effizient eine Liste von URLs zu einem Thema oder Stichwort zu extrahieren, sind leistungsfähige Internet-Suchmaschinen mit einem möglichst umfassenden und aktuellen Datenbestand notwendig. Diese sind jedoch sowohl in ihren Eigenschaften wie Verarbeitungskapazität und Netzanbindung beschränkt als auch durch administrative Hindernisse wie das Robots Exclusion Agreement. Es ist daher notwendig, neuartige Algorithmen zur Sammlung von Internet-Seiten zu verwenden, welche empirisch gewonnenes Wissen über die Seitenstruktur berücksichtigen. Dieser Bericht präsentiert den aktuellen Stand der Optimierung des Datenbeschaffungsteils der bekannten deutschen Suchmaschine www.crawler.de durch die Integration von Mechanismen, welche die Aktualisierungsrate und die Verzeichnistiefe von Internet-Links berücksichtigen
