Content

Es musste also noch etwas anderes in dieser Anrufung des Content mitschwingen, eine verborgene und doch umso entschiedenere Abgrenzung vom digitalen Nicht-Content, der bloßen "Form", den inhaltsleeren Hüllen und körperlosen Oberflächen des Internet, deren Scheitern und Ende hier verkündet werden sollte. Der bis' dahin als hohl, flach und uneigentlich geltende Cyberspace, sollte mit einer neuen Substanz gefüllt werden, und zwar nicht mit einer bestimmten, sondern mit Substanz schlechthin. Diese Metaphysik des Content fand ihre perfekte Repräsentation in den Berggipfeln von AltaVista - dem Logo jener Suchmaschine, die 1997-99 beinahe jede und jeder von uns benutzt haben dürfte. Zu sehen waren Berge von Content: zwei am linken oberen Bildrand aufragende, schneebedeckte Gipfel, die über einem im Vordergrund gelegenen Hochplateau thronten, das nach rechts sanft abfiel, in einen blau-weiß gepixelten Nebel überging und sich schließlich in den nur unwesentlich helleren Horizont auflöste. Von rechts nach links wurde, gezeigt: das digitale Rauschen, seine Transformation in' Bedeutung, deren Erhebung zu Inhalt und schließlich der Triumph jenes Prinzips, das über diesen Content stets den Überblick behält: AltaVista (der Blick vom Gipfel, auf spanisch). Dieses Bild unterschied sich nicht nur, radikal von den meist bis zur Unkenntlichkeit abstrahierten Emblemen der Konkurrenz, sondern zeigte zugleich das Internet als Ganzes: in jenem Moment, als Content King war und über ein Königreich herrschte, das keine Grenzen kannte. Natürlich hatten auch die Betreiber von AltaVista darauf gewettet, dass sich mit Websites Geld verdienen ließe. Ihre Idee bestand darin, mehr Inhalte auffindbar zu machen als jede Suchmaschine zuvor, und das mit dem Verkauf von Werbebannern zu finanzieren, die auf noch mehr Inhalte verweisen sollten. Dass sich aber mit Websites kein Geld verdienen lässt - und das zeigt sich gerade an AltaVista - liegt weder an fehlenden Usern noch an fehlender Bandbreite (von beiden hatte die Suchmaschine mehr als genug), sondern eben genau am Content, genauer: an dessen sprichwörtlicher Flüchtigkeit. Content nämlich ist nicht bloß personalintensiv (also teuer) in der Herstellung und nur schwer in eine verkäufliche Form zu bringen, sondern hat zudem die Tendenz, sich sowohl permanent wieder in Rauschen aufzulösen wie am rechten Bildrand des AltaVista-Logos), als auch ständig zu solchen Massen von Bedeutung zusammenzuklumpen (linker Bildrand), dass er ins rein Tautologische umkippt. Die beiden letzgenannten Phänomene wurden schließlich zu einem inhaltlichen Problem der Suchmaschine selbst:

Abstract

Information subject gateways provide targeted discovery services for their users, giving access to Web resources selected according to quality and subject coverage criteria. Information gateways recognise that they must collaborate on a wide range of issues relating to content to ensure continued success. This report is informed by discussion of content activities at the 1999 Imesh Workshop. The author considers the implications for subject based gateways of co-operation regarding coverage policy, creation of metadata, and provision of searching and browsing across services. Other possibilities for co-operation include working more closely with information providers, and diclosure of information in joint metadata registries

Abstract

Amid the rapid growth of information today is the increasing challenge for people to navigate its magnitude. Dynamics and heterogeneity of large information spaces such as the Web raise important questions about information retrieval in these environments. Collection of all information in advance and centralization of IR operations are extremely difficult, if not impossible, because systems are dynamic and information is distributed. The chapter discusses some of the key issues facing classic information retrieval models and presents a decentralized, organic view of information systems pertaining to search in large scale networks. It focuses on the impact of network structure on search performance and discusses a phenomenon we refer to as the Clustering Paradox, in which the topology of interconnected systems imposes a scalability limit.

Abstract

The study sets out to explore the factors that influence the evaluation of information and the judgments made in the process of finding useful information in web search contexts. Based on a diary study of 2 assigned tasks to search on Google and Google Scholar, factor analysis identified the core constructs of content, relevance, scope, and style, as well as informational and system "ease of use" as influencing the judgment that useful information had been found. Differences were found in the participants' evaluation of information across the search tasks on Google and on Google Scholar when identified by the factors related to both content and ease of use. The findings from this study suggest how searchers might critically evaluate information, and the study identifies a relation between the user's involvement in the information interaction and the influences of the perceived system ease of use and information design.

Abstract

Presents a view of portal sites as a radically different model from those currently embraced by traditional information companies. The concept of a portal as a starting point that Web users pass through is an uncomfortable one for most traditional services, which are designed to be one-stop destinations for information. It will become increasingly difficult for even the largest data warehouses to compete with the rising volume of Web content if closed end information models are not abandoned in favour of distributed ones which better reflect the reality of what is available to information consumers. Dow Jones Interactive Publishing is among the first to embrace a distributed model by indexing the sites which it believes have customer value, regardless of whether they offer their content on the subscriber service

Abstract

This book provides practical strategies which enable the advanced web user to locate information effectively and to form a precise evaluation of the accuracy of that information. Although the book provides a brief but thorough review of the technologies which are currently available for these purposes, most of the book concerns practical `future-proof' techniques which are independent of changes in the tools available. For example, the book covers: how to retrieve salient information quickly; how to remove or compensate for bias; and tuition of novice Internet users.

Content

Key Features - Importantly, the book enables readers to develop strategies which will continue to be useful despite the rapidly-evolving state of the Internet and Internet technologies - it is not about technological `tricks'. - Enables readers to be aware of and compensate for bias and errors which are ubiquitous an the Internet. - Provides contemporary information an the deficiencies in web skills of novice users as well as practical techniques for teaching such users. The Authors Dr Alison Stacey works at the Learning Resource Centre, Cambridge Regional College. Dr Adrian Stacey, formerly based at Cambridge University, is a software programmer. Readership The book is aimed at a wide range of librarians and other information professionals who need to retrieve information from the Internet efficiently, to evaluate their confidence in the information they retrieve and/or to train others to use the Internet. It is primarily aimed at intermediate to advanced users of the Internet. Contents Fundamentals of information retrieval from the Internet - why learn web searching technique; types of information requests; patterns for information retrieval; leveraging the technology: Search term choice: pinpointing information an the web - why choose queries carefully; making search terms work together; how to pick search terms; finding the 'unfindable': Blas an the Internet - importance of bias; sources of bias; usergenerated bias: selecting information with which you already agree; assessing and compensating for bias; case studies: Query reformulation and longer term strategies - how to interact with your search engine; foraging for information; long term information retrieval: using the Internet to find trends; automating searches: how to make your machine do your work: Assessing the quality of results- how to assess and ensure quality: The novice user and teaching internet skills - novice users and their problems with the web; case study: research in a college library; interpreting 'second hand' web information.

Abstract

The World Wide Web was created in 1989, but it has already become a major information channel and source, influencing our everyday lives, commercial transactions, and scientific communication, to mention just a few areas. The seventeenth-century philosopher Descartes proclaimed, "I think, therefore I am" (cogito, ergo sum). Today the Web is such an integral part of our lives that we could rephrase Descartes' statement as "I have a Web presence, therefore I am." Because many people, companies, and organizations take this notion seriously, in addition to more substantial reasons for publishing information an the Web, the number of Web pages is in the billions and growing constantly. However, it is not sufficient to have a Web presence; tools that enable users to locate Web pages are needed as well. The major tools for discovering and locating information an the Web are search engines. This review discusses the use of Web search engines in information science research. Before going into detail, we should define the terms "information science," "Web search engine," and "use" in the context of this review.
