"Am Anfang war Ananova. Die grünäugige Schönheit liest Nachrichten vor, lächelt dabei freundlich, schlägt die Augen auf und nieder. Nie verspricht sie sich. Letztere Qualität sollte auch Begriffsstutzigen deutlich machen, dass diese Nachrichtensprecherin nicht aus Fleisch und Blut ist. Ananova besteht aus Bytes, vom dunklen Haarschopf bis zu, den schlanken Füßen. Und seit sie im Frühjahr ihr Debüt als Aushängeschild der ehrwürdigen britischen Press Association (PA) gefeiert hat, gilt als ausgemacht, dass im Internet die Zeit der Cyberbabes angebrochen ist. Für die PA war die Idee, eine virtuelle Nachrichtensprecherin zu entwickeln, ein Risiko. Würden die Kunden, die von der PA vor allem seriöse Berichterstattung ohne Glanz und Glamour erwarten, diesen Bruch mit der Tradition dulden? Genau das taten sie - Ananova ist eines der bestbesuchten britischen Nachrichtenangebote im Internet. Vor allem jüngere Nutzer gehören zu den Fans. Damit hat die PA ihr Ziel erreicht: Den teuren Investitionen ins Internet sollten endlich Deckungsbeiträge durch Werbung entgegengestellt werden. Diese Aufgabe erfüllt Ananova mit Leichtigkeit - und verkauft nebenher so allerlei Dinge, die das Leben angenehmer machen oder einfach nur den Kunden um ein paar Pfund erleichtern. Die Provision landet bei der PA. Letztlich hat sich das Risiko vor allem dadurch bezahlt gemacht, dass der Mobiltelefonkonzern Orange, ein Ableger von France Telecom, die weltweiten Nutzungsrechte an dem Cybergeschöpf für die stolze- Summe von umgerechnet über 300 Millionen Mark erworben hat. Das fordert die Nachfolgerinnen heraus - auch wenn Ananovas Schwestern nicht auf das schnöde Lesen von Nachrichten beschränkt sind. Sie sollen vor allem dazu dienen, den E-Commerce anzukurbeln. Dazu werden diese Kreuzungen aus Emma Peel und Karlheinz Köpcke von ihren meist männlichen Programmierern reich]ich mit sekundaren Geschlechtsmerkmalen ausgestattet. Weisheiten der realen Welt gelten nun mal auch im Internet: Sex sells, selbst wenn es nur Cybersex ist. Die neue Generation der Ananovas hört auf den schönen Namen Eva, oder auf den weniger schönen Namen TMmy: Die Softwareschmiede Stratumsoft hat rund 60 der Cyberwesen auf Halde und wartet nun auf Abnehmer. Die Konkurrenz von Digital Animations Group, Schöpfer von Ananova, stellten TMmy kürzlich beim Edinburgh Festival vor Vor allem beim Kundenkontakt sollen die Cyberbabes eingesetzt werden: Der größte Teil der Anfragen in jedem Call Center könne mit standardisierten Antworten abgehandelt werden, argumentiert Stratumsoft. Da in relativ kurzer Zeit ein großer Teil solcher Anfragen über das Internet abgewickelt werden, sei für derartige Routiiie-Arbeit eine charmante Cyber-Dame genau die Richtige. Und Kundendienst wird immer bedeutender, besonders beim E-Commerce: Nach einer Studie des US-Marktanalysten Creative Good verlieren Cyber-Händler pro Jahr mehr als 13 Milliarden Mark an Umsatz durch mangelnde Kundenbetreuung. Da sind rund 350 000 Mark Investition für eine Cyberdame beinahe Kleingeld. Der Trick bei den Evas und TMmys ist ihre Internet-Tauglichkeit: Sie sind ladefreundliche Java-Applikationen, die keine allzu langen Downloads verursachen. Klug hat dabei die Erfahrung gemacht: Der in Konkurs gegangene Modehändler Boo.com verdross tausende potenzielle Käufer durch die quälend langen Ladezeiten der Cyber-Verkäuferin Miss Boo. Die Einsatzmöglichkeiten, der künstlichen Wesen sind fast unbeschränkt. So 'dürfte eine nach persönlichen Maßen und Fettpölsterchen einstellbare, Cyberlady nur noch eine, Frage der Zeit sein. Die kann dann anprobieren, was online gekauft werden soll. Was allerdings nur der Übergangsstadium dazu sein dürfte, dass jeder seinen eigenen Cyber-Ableger im Internet zum Shopping schicken kann. Diese so genannten Avatare sind zwar heute noch recht primitiv - aber wir wissen ja, dass Cyberjahre schnell vergehen."

Abstract

Discusses various structural searching methods available on the Web. some databases such as the Brookhaven Protein Database use keyword searching which does not provide the desired substructure search capabilities. Others like CS ChemFinder and MDL's Chemscape use graphical plug in programs. Although plug in programs provide more capabilities, users first have to obtain a copy of the programs. Due to this limitation, Tripo's WebSketch and ACD Interactive Lab adopt a different approach. Using JAVA applets, users create and display a structure query of the molecule on the web page without using other software. The new technique is likely to extend itself to other electronic publications

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

Many information professionals feel that the time is still far off when the WWW can offer the combined funtionality and content of traditional online and CD-ROM databases, but there have been a number of recent Web developments to reflect on. Describes the testing and launch by Ovid of its Java client which, in effect, allows access to its databases on the Web with full search functionality, and the initiative of Euromonitor in providing Web access to its whole collection of consumer research reports and its entire database of business sources. Also reviews the service of a newcomer to the information scene, Information Quest (IQ) founded by Dawson Holdings which has made an agreement with Infonautics to offer access to its Electric Library database thus adding over 1.000 reference, consumer and business publications to its Web based journal service

Abstract

Examines some of the advanced tools, techniques, methods and standards related to the Internet and WWW which consist of hybrids of documents and software, called 'document program hybrids'. Early Internet systems were based on having documents on one side and software on the other, neatly separated, apart from one another and without much interaction, so that the static document can also exist without computers and networks. Documentation program hybrids blur this classical distinction and all components are integrated, interwoven and exist in synergy with each other. Illustrates the techniques with particular reference to practical examples, including: dara collections and dedicated software; advanced HTML features on the WWW, multimedia viewer and plug in software for Internet and WWW browsers; VRML; interaction through a Web server with other servers and with instruments; adaptive hypertext provided by the server; 'webbots' or 'knowbots' or 'searchbots' or 'metasearch engines' or intelligent software agents; Sun's Java; Microsoft's ActiveX; program scripts for HTML and Web browsers; cookies; and Internet push technology with Webcasting channels

Abstract

A unique collection of historical material covering the lives and events of an English village between 1400 and 1750 has been made available via a WWW enabled information retrieval system. Since the expected readership of the documents ranges from school children to experienced researchers, providing this information in an easily accessible form has offered many challenges requiring tools to aid searching and browsing. The file structure of the document collection was replaced by an database, enabling query results to be presented on the fly. A Java interface displays each user's context in a form that allows for easy and intuitive relevance feedback

Abstract

Presents an approach that integrates searching and browsing in a manner that improves both paradigms. When browsing is the primary task, it enables semantic content-based tailoring of Web maps in both the generation as well as the visualization phases. When search is the primary task, it enables contextualization of the results by augmenting them with the documents' neighbourhoods. This approach is embodied in WebCutter, a client-server system fully integrated with Web software. WebCutter consists of a map generator running off a standard Web server and a map visualization client implemented as a Java applet runalble from any standard Web browser and requiring no installation or external plug-in application. WebCutter is in beta stage and is in the process of being integrated into the Lotus Domino application product line

Abstract

The KMODDL (kinematic models for design digital library) is a digital library based on a historical collection of kinematic models made of steel and bronze. The digital library contains four types of learning modules including textual materials, QuickTime virtual reality movies, Java simulations, and stereolithographic files of the physical models. The authors report an evaluation study on the uses of the KMODDL in two undergraduate classes. This research reveals that the users in different classes encountered different usability problems, and reported quantitatively different subjective experiences. Further, the results indicate that depending on the subject area, the two user groups preferred different types of learning modules, resulting in different uses of the available materials and different learning outcomes. These findings are discussed in terms of their implications for future digital library design.

Abstract

Argues that a cataloguer's personal home page, with a list of links to most used sites, simplifies the task of retrieving WWW base documentation for name and subject heading authority records. Highlights selected WWW sites for geographic names, historic buildings and topics in art, suggests reasons for creating one's own site, and offers an example of a personal home page

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 World Wide Web. 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 to 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 the 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. The search is carried out an index entries derived from the faceted subject heading using the 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 Keadings is too large (running into more than a page) the user has the option of entering another search term to be searched in combination. The System searches subject headings already retrieved and looks 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 in a Windows NT environment using ASP and a web server is under rigorous testing. The database and Index management routines need further development.

Abstract

How the Internet Works promises "an exciting visual journey down the highways and byways of the Internet," and it delivers. The book's high quality graphics and simple, succinct text make it the ideal book for beginners; however it still has much to offer for Net vets. This book is jam- packed with cool ways to visualize how the Net works. The first section visually explores how TCP/IP, Winsock, and other Net connectivity mysteries work. This section also helps you understand how e-mail addresses and domains work, what file types mean, and how information travels across the Net. Part 2 unravels the Net's underlying architecture, including good information on how routers work and what is meant by client/server architecture. The third section covers your own connection to the Net through an Internet Service Provider (ISP), and how ISDN, cable modems, and Web TV work. Part 4 discusses e-mail, spam, newsgroups, Internet Relay Chat (IRC), and Net phone calls. In part 5, you'll find out how other Net tools, such as gopher, telnet, WAIS, and FTP, can enhance your Net experience. The sixth section takes on the World Wide Web, including everything from how HTML works to image maps and forms. Part 7 looks at other Web features such as push technology, Java, ActiveX, and CGI scripting, while part 8 deals with multimedia on the Net. Part 9 shows you what intranets are and covers groupware, and shopping and searching the Net. The book wraps up with part 10, a chapter on Net security that covers firewalls, viruses, cookies, and other Web tracking devices, plus cryptography and parental controls.

Abstract

This paper focuses on the need for knowledge organization (KO) tools, such as library classifications, thesauri and subject heading systems, to be fully disclosed and available in the open network environment. The authors look at the place and value of traditional library knowledge organization tools in relation to the technical environment and expectations of the Semantic Web. Future requirements in this context are explored, stressing the need for KO systems to support semantic interoperability. In order to be fully shareable KO tools need to be reframed and reshaped in terms of conceptual and data models. The authors suggest that some useful approaches to this already exist in methodological and technical developments within the fields of ontology modelling and lexicographic and terminological data interchange.

Abstract

Some web sites "work" and some don't. Good web site consultants know that you can't just jump in and start writing HTML, the same way you can't build a house by just pouring a foundation and putting up some walls. You need to know who will be using the site, and what they'll be using it for. You need some idea of what you'd like to draw their attention to during their visit. Overall, you need a strong, cohesive vision for the site that makes it both distinctive and usable. Information Architecture for the World Wide Web is about applying the principles of architecture and library science to web site design. Each web site is like a public building, available for tourists and regulars alike to breeze through at their leisure. The job of the architect is to set up the framework for the site to make it comfortable and inviting for people to visit, relax in, and perhaps even return to someday. Most books on web development concentrate either on the aesthetics or the mechanics of the site. This book is about the framework that holds the two together. With this book, you learn how to design web sites and intranets that support growth, management, and ease of use. Special attention is given to: * The process behind architecting a large, complex site * Web site hierarchy design and organization Information Architecture for the World Wide Web is for webmasters, designers, and anyone else involved in building a web site. It's for novice web designers who, from the start, want to avoid the traps that result in poorly designed sites. It's for experienced web designers who have already created sites but realize that something "is missing" from their sites and want to improve them. It's for programmers and administrators who are comfortable with HTML, CGI, and Java but want to understand how to organize their web pages into a cohesive site. The authors are two of the principals of Argus Associates, a web consulting firm. At Argus, they have created information architectures for web sites and intranets of some of the largest companies in the United States, including Chrysler Corporation, Barron's, and Dow Chemical.
