Abstract

In meinem Buch CyberSociety: Computer-Mediated Communication and Community habe ich Begriffe, die gewöhnlich dazu gebraucht werden, um das Internet zu beschreiben, als unglücklich gewählte Metaphern kritisiert - so wie in den USA »Information Highway« und »National Information Infrastructure«. Sie sind unglücklich, weil sie viel intellektuellen und sozialen Ballast mit sich tragen, den sie sich durch verblüffende Parallelen zwischen dem gegenwärtigen Projekt des »Information Superhighway« und dem Highway-Projekt aufladen, das in Amerika zur Zeit der Weltkriege durchgeführt wurde - wie etwa das Vertrauen in das Wort »Highway« und seine romantische Konnotation der freien Fahrt. Eine andere wichtige Parallele ist die zwischen dem ursprünglich militärisch motivierten Bau von Autobahnen (die bereits auf Thomas Jefferson zurückgeht) und den militärischen Ursprüngen des prominentesten Informationsnetzes, des Internet, in dem das Computernetzwerk des Verteidigungsministeriums mit den Forschungszentren der Universitäten verbunden worden ist. Schließlich besteht eine weitere Parallele zwischen dem »Weltraumwettrennen« der sechziger Jahre und unserem anhaltenden Streben, bei neuen Technologien und Wissenschaften führend zu sein.

Abstract

Reprots the results of a study which sought indications of the effectiveness of searching for information on the WWW versus the traditional online vendors, for comparisons of how it took to search, and for comments on the relative value of the results retrieved. Professional searchers were invited to search for answers to the same questions on both the WWW and on either DIALOG or Dow Jones Interactive. Overall DIALOG / Dow Jones Interactive retrieved more relevant documents and total searching time was more than double for finding information on the Web. Summarizes the comments from searchers on: searching assumptions of professional searchers; the subjects and types of searches for which DIALOG and Dow Jones Interactive showed superiority; areas where the Web has advantages over traditional online services; and uses for which both traditional online vendors and the Web can supplement each other. Lists nine searching principles for maximizing success when using Web search engines

Abstract

Internet heißt das derzeit wichtigste Symbol der technologischen Entwicklung des ausgehenden 20. Jahrhunderts. Wer bereits connected ist, ahnt, wie wenig Geheimis sich tatsächlich hinter dem Schleier verbirgt. Der erste Rausch ist dahin, und es ist an der Zeit, einen unverstellten Blick auf die Chancen und Risiken der Netzwelten zu werfen. Der Band versammelt Beiträge von Autoren, die sich aus verschiedenen Perspektiven philosophischer, ökonomischer, politischer und kultureller Fragen dem Phänomen der neuen Netzwelt nähern. Gedacht als kritische Ein- und Weitertührung, richten sich die Beiträge an all jene, welche die Gegenwart besser verstehen wollen.

Abstract

Briefly summarizes the report, presented at the 1998 National Online Meeting, of the results of the Information today sponsored Internet search challenge to compare the searching of the WWW with traditional online search services (such as DIALOG or Dow Jones). Results indicated that the WWW takes at least twice as long as traditional methods. Relevance ratings were also found to be lower on WWW services

Abstract

Organizing and providing access to the resources an the Internet has been a problem area in spite of the availability of sophisticated search engines and other Software tools. There have been several attempts to organize the resources an the WWW. Some of them have tried to use traditional library classification schemes such as the Library of Congress Classification, the Dewey Decimal Classification and others. However there is a need to assign proper subject headings to them and present them in a logical or hierarchical sequence to cater to the need for browsing. This paper attempts to describe an experimental system designed to organize and provide access to web documents using a faceted pre-coordinate indexing system based an the Deep Structure Indexing System (DSIS) derived from POPSI (Postulate based Permuted Subject Indexing) of Bhattacharyya, and the facet analysis and chain indexing System of Ranganathan. A prototype software system has been designed to create a database of records specifying Web documents according to the Dublin Core and input a faceted subject heading according to DSIS. Synonymous terms are added to the standard terms in the heading using appropriate symbols. Once the data are entered along with a description and URL of the Web document, the record is stored in the system. More than one faceted subject heading can be assigned to a record depending an the content of the original document. The system stores the surrogates and keeps the faceted subject headings separately after establishing a link. Search is carried out an index entries derived from the faceted subject heading using chain indexing technique. If a single term is input, the system searches for its presence in the faceted subject headings and displays the subject headings in a sorted sequence reflecting an organizing sequence. If the number of retrieved headings is too large (running into more than a page) then the user has the option of entering another search term to be searched in combination. The system searches subject headings already retrieved and look for those containing the second term. The retrieved faceted subject headings can be displayed and browsed. When the relevant subject heading is selected the system displays the records with their URLs. Using the URL the original document an the web can be accessed. The prototype system developed under Windows NT environment using ASP and web server is under rigorous testing. The database and indexes management routines need further development.

Abstract

The past 100 years have seen the development of numerous systems for the structured representation of knowledge and information, including hierarchical classification systems and with sophisticated features for the representation of term relationships. Discusses reasons for the lack of widespread adoption of these systems, particularly in the USA. The suggested structure for indexing the Internet or other large electronic collections of documents is based on that of book indexes: specific headings with coined modifications

Abstract

As the amount of accessible information on the WWW increases, so will the cost of accessing it, even if search servcies remain free, due to the increasing amount of time users will have to spend to find needed items. Considers what the seemingly unorganized Web and the organized world of libraries can offer each other. The OCLC Scorpion Project is attempting to combine indexing and cataloguing, specifically focusing on building tools for automatic subject recognition using the technqiues of library science and information retrieval. If subject headings or concept domains can be automatically assigned to electronic items, improved filtering tools for searching can be produced

Abstract

WWW sites, consisting mainly of links to other Internet resources, have begun to proliferate and these sites are valuable to library users and researchers because they bring together in a single Web site links to a comprehensive array of information resources. Because libraries may elect to include bibliographic records for these sites in their online catalogues, cataloguers should be aware of some of the main aspects of cataloguing this new type of resource. Concludes that cataloguers should be aware of the main types and different characteristics of these Web sites, how to describe them in bibliographic records and how to assign appropriate subject headings for them

Abstract

While many catalogers are using the Web to find the information they need to perform authority work quickly and accurately, the full potential of the Web to assist catalogers in name authority work has yet to be realized. The ever-growing nature of the Web means that available information for creating personal name, corporate name, and other types of headings will increase. In this article, we examine ways in which simple and effective Web searching can save catalogers time and money in the process of authority work. In addition, questions involving evaluating authority information found on the Web are explored.

Abstract

Reports results of a questionnaire survey of cataloguers, conducted over the AUTOCAT Internet discussion group, to determine those areas of cataloguing for which the Internet is a valuable tool and those areas for which it is not as useful. Respondents indicated 4 areas in which cataloguers use the Internet: searching the OPACs of other libraries, communicating with colleagues, accessing online cataloguing documentation and publications, and authority work. Cataloguers who found access to other libraries' OPACs did so for the following reasons: assigning call numbers and subject headings; finding full cataloguing copy from other libraries; enriching their local catalogue with notes present in records in other libraries; finding copy for foreign language items that cannot be read by library staff; and resolving difficult problems when important parts of the item are missing ar are in disarray. Some cataloguers also related processes for which they have found the Internet to not be efficient
