Abstract

Zu den großen Herausforderungen einer sinnvollen Suche im WWW gehören die riesige Menge des Verfügbaren und die Sparchbarrieren. Verfahren, die die Web-Ressourcen im Hinblick auf ein effizienteres Retrieval inhaltlich strukturieren, werden daher ebenso dringend benötigt wie Programme, die mit der Sprachvielfalt umgehen können. Im folgenden Vortrag werden wir einige Ansätze diskutieren, die zur Bewältigung der beiden Probleme derzeit unternommen werden

Abstract

Aufgrund der so großen Bedeutung von Privatheit im Internet hat acatech, die Deutsche Akademie der Technikwissenschaften, 2011 ein Projekt initiiert, das sich mit dem Privatheitsparadoxon wissenschaftlich auseinandersetzt. In dem Projekt werden Empfehlungen entwickelt, wie sich eine Kultur der Privatheit und des Vertrauens im Internet etablieren lässt, die es ermöglicht, das Paradoxon aufzulösen. Wir verwenden hier den Begriff der Privatheit. Er deutet an, dass hier nicht nur der räumliche Begriff Privatsphäre gemeint ist, sondern auch das im europäischen Kontext wichtige Konzept der informationellen Selbstbestimmung einbezogen ist. Dieser Band legt die Ergebnisse der ersten Projektphase vor: eine Bestandsaufnahme von Privatheit im Internet aus verschiedenen Blickwinkeln. Kapitel 1 stellt die Wünsche und Befürchtungen von Internetnutzern und Gesellschaft im Hinblick auf ihre Privatheit vor. Sie wurden mithilfe sozialwissenschaftlicher Methoden untersucht. Ergänzend dazu untersucht das zweite Kapitel Privatheit im Cyberspace aus ethischer Perspektive. Das dritte Kapitel widmet sich ökonomischen Aspekten: Da viele Onlinedienstleistungen mit Nutzerdaten bezahlt werden, ergibt sich die Frage, was dies sowohl für den Nutzer und Kunden als auch für die Unternehmen bedeutet. Kapitel 4 hat einen technologischen Fokus und analysiert, wie Privatheit von Internettechnologien bedroht wird und welche technischen Möglichkeiten es gibt, um die Privatheit des Nutzers zu schützen. Selbstverständlich ist der Schutz von Privatheit im Internet nicht nur ein technisches Problem. Deshalb untersucht Kapitel 5 Privatheit aus rechtlicher Sicht. Bei der Lektüre der fünf Kapitel wird dem Leser sofort die Komplexität der Frage von Privatheit im Internet (Internet Privacy) bewusst. Daraus folgt die unbedingte Notwendigkeit eines interdisziplinären Ansatzes. In diesem Sinne wird die interdisziplinäre Projektgruppe gemeinsam Optionen und Empfehlungen für einen Umgang mit Privatheit im Internet entwickeln, die eine Kultur der Privatheit und des Vertrauens im Internet fördern. Diese Optionen und Empfehlungen werden 2013 als zweiter Band dieser Studie veröffentlicht.

Abstract

The BAER Web Resources Group was charged in October 1999 with defining and describing the parameters of electronic resources that do not clearly belong to the categories being defined by the BAER Digital Group or the BAER Electronic Journals Group. After some difficulty identifying precisely which resources fell under the Group's charge, we finally named the following types of resources for our consideration: web sites, electronic texts, indexes, databases and abstracts, online reference resources, and networked and non-networked CD-ROMs. Electronic resources are a vast and growing collection that touch nearly every department within the Library. It is unrealistic to think one department can effectively administer all aspects of the collection. The Group then began to focus on the concern of bibliographic access to these varied resources, and to define parameters for handling or processing them within the Library. Some key elements became evident as the work progressed. * Selection process of resources to be acquired for the collection * Duplication of effort * Use of CORC * Resource Finder design * Maintenance of Resource Finder * CD-ROMs not networked * Communications * Voyager search limitations. An unexpected collaboration with the Web Development Committee on the Resource Finder helped to steer the Group to more detailed descriptions of bibliographic access. This collaboration included development of data elements for the Resource Finder database, and some discussions on Library staff processing of the resources. The Web Resources Group invited expert testimony to help the Group broaden its view to envision public use of the resources and discuss concerns related to technical services processing. The first testimony came from members of the Resource Finder Committee. Some background information on the Web Development Resource Finder Committee was shared. The second testimony was from librarians who select electronic texts. Three main themes were addressed: accessing CD-ROMs; the issue of including non-networked CD-ROMs in the Resource Finder; and, some special concerns about electronic texts. The third testimony came from librarians who select indexes and abstracts and also provide Reference services. Appendices to this report include minutes of the meetings with the experts (Appendix A), a list of proposed data elements to be used in the Resource Finder (Appendix B), and recommendations made to the Resource Finder Committee (Appendix C). Below are summaries of the key elements.

Rez. in: ZfBB 51(2004) H.2, S.116-118 (H. Jüngling): "Das überspitzt gezeichnete Bild vom Ingenieur,der nur mit Rechenschieber und Zeichenbrett ausgestattet und ohne weitere Hilfsmittel im stillen Kämmerlein erfolgreich neue, nützliche Maschinen konstruiert, stimmt schon lange nicht mehr. Zwar haben Ingenieure die Unterstützung durch moderne Rechner in der täglichen Praxis nicht nur gerne und zügig schätzen gelernt, sie waren sogar häufig Vorreiter bei deren (Weiter-)Entwicklung und Nutzung. Zur Beschaffung von Informationen jedweder Art wurden Rechner dagegen zunächst überaus zögerlich angenommen und gewannen - wie allerdings in vielen anderen Wissenschaftsbereichen auch -für diese Verwendung im Grunde erst durch die Möglichkeiten des Internets an Akzeptanz und Bedeutung. Erste Initiativen, dem möglicherweise spezifischen Informationsbedarf von Ingenieuren entgegenzukommen und der Engineering Community »runde« Angebote zu machen, gehen auf die Mitte der 90er-Jahre zurück. So sind 1994/95 u.a. die Engineering Electronic Library, Sweden (EELS, 1994),2 das Engineering Village von Engineering Information Inc., NewYork (1995)3 und die Edinburgh Engineering Virtual Library (EEVL, 1995)4 entstanden. Zum Vergleich sei angemerkt, dass konkrete Planungen für die Virtuelle Fachbibliothek Technik (ViFaTec)s der TIB/DFG erst 1997/98 einsetzten. Nach anfänglicher Euphorie hat sich bekanntermaßen relativ schnell gezeigt, dass derartige Angebote trotz teilweise überregionaler Zusammenarbeit nicht ohne erheblichen finanziellen Aufwand zu kreieren und vor allem aufrecht zu erhalten und zu pflegen sind.So hat z.B.die zweite Generation des Engineering Village von früheren, relativ hoch gesteckten Zielen Abstand genommen. Die EELS hat ihr Angebot bereits vor etwa einem Jahr »eingefroren«. Dagegen scheint die EEVL noch immer recht lebendig zu sein. U. a. deshalb soll hier näher darauf eingegangen werden. ..."

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

Many libraries manage Web sites intended to provide their users with online resources suitable for answering reference questions. Most of these sites can be analyzed in terms of their depth, and their organizing and searching features. Composing a typology based on these factors sheds light on the critical design decisions that influence whether users of these sites succees or fail to find information easily, rapidly and accurately. The same analysis highlights some larger design issues, both for Web sites and for information management at large

Abstract

Google or Wikipedia? Those of us who search online -- and who doesn't? -- are getting referred more and more to Wikipedia. For the past two years, this free online "encyclopedia of the people" has been topping the lists of the world's most popular websites. But do we really know what we're using? Backlight plunges into the story behind Wikipedia and explores the wonderful world of Web 2.0. Is it a revolution, or pure hype? Director IJsbrand van Veelen goes looking for the truth behind Wikipedia. Only five people are employed by the company, and all its activities are financed by donations and subsidies. The online encyclopedia that everyone can contribute to and revise is now even bigger than the illustrious Encyclopedia Britannica. Does this spell the end for traditional institutions of knowledge such as Britannica? And should we applaud this development as progress or mourn it as a loss? How reliable is Wikipedia? Do "the people" really hold the lease on wisdom? And since when do we believe that information should be free for all? In this film, "Wikipedians," the folks who spend their days writing and editing articles, explain how the online encyclopedia works. In addition, the parties involved discuss Wikipedia's ethics and quality of content. It quickly becomes clear that there are camps of both believers and critics. Wiki's Truth introduces us to the main players in the debate: Jimmy Wales (founder and head Wikipedian), Larry Sanger (co-founder of Wikipedia, now head of Wiki spin-off Citizendium), Andrew Keen (author of The Cult of the Amateur: How Today's Internet Is Killing Our Culture and Assaulting Our Economy), Phoebe Ayers (a Wikipedian in California), Ndesanjo Macha (Swahili Wikipedia, digital activist), Tim O'Reilly (CEO of O'Reilly Media, the "inventor" of Web 2.0), Charles Leadbeater (philosopher and author of We Think, about crowdsourcing), and Robert McHenry (former editor-in-chief of Encyclopedia Britannica). Opening is a video by Chris Pirillo. The questions surrounding Wikipedia lead to a bigger discussion of Web 2.0, a phenomenon in which the user determines the content. Examples include YouTube, MySpace, Facebook, and Wikipedia. These sites would appear to provide new freedom and opportunities for undiscovered talent and unheard voices, but just where does the boundary lie between expert and amateur? Who will survive according to the laws of this new "digital Darwinism"? Are equality and truth really reconcilable ideals? And most importantly, has the Internet brought us wisdom and truth, or is it high time for a cultural counterrevolution?

Abstract

Increased enrollments, changing student expectations, and shifting patterns of Internet access and usage continue to generate resource and administrative challenges for colleges and universities. Computer center staff and college administrators must balance increased access demands, changing system loads, and system security within constrained resources. To assess the changing academic computing environment, computer center directors from several geographic regions were asked to respond to an online questionnaire that assessed patterns of usage, resource allocation, policy formulation, and threats. Survey results were compared with data from a study conducted by the authors in 1999. The analysis includes changing patterns in Internet usage, access, and supervision. The paper also presents details of usage by institutional type and application as well as recommendations for more precise resource assessment by college administrators.
