- Abstract
- After a short outline of problems, possibilities and difficulties of systematic information retrieval on the Internet and a description of efforts for development in this area, a specification of the terminology for this report is required. Although the process of retrieval is generally seen as an iterative process of browsing and information retrieval and several important services on the net have taken this fact into consideration, the emphasis of this report lays on the general retrieval tools for the whole of Internet. In order to be able to evaluate the differences, possibilities and restrictions of the different services it is necessary to begin with organizing the existing varieties in a typological/ taxonomical survey. The possibilities and weaknesses will be briefly compared and described for the most important services in the categories robot-based WWW-catalogues of different types, list- or form-based catalogues and simultaneous or collected search services respectively. It will however for different reasons not be possible to rank them in order of "best" services. Still more important are the weaknesses and problems common for all attempts of indexing the Internet. The problems of the quality of the input, the technical performance and the general problem of indexing virtual hypertext are shown to be at least as difficult as the different aspects of harvesting, indexing and information retrieval. Some of the attempts made in the area of further development of retrieval services will be mentioned in relation to descriptions of the contents of documents and standardization efforts. Internet harvesting and indexing technology and retrieval software is thoroughly reviewed. Details about all services and software are listed in analytical forms in Annex 1-3.

- Abstract
- Knowledge Organization Systems can comprise thesauri and other controlled lists of keywords, ontologies, classification systems, clustering approaches, taxonomies, gazetteers, dictionaries, lexical databases, concept maps/spaces, semantic road maps, etc. These schemas enable knowledge structuring and management, knowledge-based data processing and systematic access to knowledge structures in individual collections and digital libraries. Used as interactive information services on the Internet they have an increased potential to support the description, discovery and retrieval of heterogeneous information resources and to contribute to an overall resource discovery infrastructure

- Enthält die Bemerkung: "The problems of indexing and categorization of information in principle lie within the purview of library and information science communities, but to date theirs has been a curiously low profile in the electronic realm, while various amateur brute-force indexing schemes are running dangerously amok. It would be remarkable if centuries of ostensibly relevant experience will find little applicability in the network context"

Allerdings wird hier und da bereits mit Bezugnahme auf das sogenannte Semantic Web von einer dritten und mancherorts von einer vierten Generation des Web gesprochen. Der Vortrag hinterfragt kritisch, welche Konzepte sich hinter diesen Bezeichnungen verbergen und geht der Frage nach, welche Herausforderungen eine Übernahme dieser Konzepte für die Bibliothekswelt mit sich bringen würde.

- Abstract
- "Zweimal täglich googeln" empfiehlt Mathias Bröckers in seinem Buch "Verschwörungen, Verschwörungstheorien und die Geheimnisse des 11.9.". Der Band gilt den gutbürgerlichen Medien von FAZ bis Spiegel als Musterbeispiel krankhafter Verschwörungstheorie. Dabei wollte der Autor - nach eigenem Bekunden - keine Verschwörungstheorie zum 11. September vorlegen, sondern lediglich auf Widersprüche und Fragwürdigkeiten in den amtlichen Darstellungen und Erklärungen der US-Regierung zu jenem Terroranschlag hinweisen. Unabhängig davon, wie ernst diese Einlassungen des Autors zu nehmen sind, ist der "Fall Bröckers" für die Erforschung von Verschwörungstheorien unter zwei Aspekten interessant: Erstens geht der Band auf ein [[extern] ] konspirologisches Tagebuch zurück, das der Autor zwischen dem 13. September 2001 und dem 22. März 2002 für das Online-Magazin Telepolis verfasst hat; zweitens behauptet Bröckers in der Einleitung zum Buch, dass er für seine Arbeit ausschließlich über das Netz zugängliche Quellen genutzt habe. Hierbei hätte ihm Google unverzichtbare Dienste geleistet: Um an die Informationen in diesem Buch zu kommen, musste ich weder über besondere Beziehungen verfügen, noch mich mit Schlapphüten und Turbanträgern zu klandestinen Treffen verabreden - alle Quellen liegen offen. Sie zu finden, leistete mir die Internet-Suchmaschine Google unschätzbare Dienste. Mathias Bröckers

- Abstract
- Purpose: To provide a critical review of Bergman's 2001 study on the Deep Web. In addition, we bring a new concept into the discussion, the Academic Invisible Web (AIW). We define the Academic Invisible Web as consisting of all databases and collections relevant to academia but not searchable by the general-purpose internet search engines. Indexing this part of the Invisible Web is central to scien-tific search engines. We provide an overview of approaches followed thus far. Design/methodology/approach: Discussion of measures and calculations, estima-tion based on informetric laws. Literature review on approaches for uncovering information from the Invisible Web. Findings: Bergman's size estimate of the Invisible Web is highly questionable. We demonstrate some major errors in the conceptual design of the Bergman paper. A new (raw) size estimate is given. Research limitations/implications: The precision of our estimate is limited due to a small sample size and lack of reliable data. Practical implications: We can show that no single library alone will be able to index the Academic Invisible Web. We suggest collaboration to accomplish this task. Originality/value: Provides library managers and those interested in developing academic search engines with data on the size and attributes of the Academic In-visible Web.
