    Rez. in: c't 2002, H.23, S.229 (T.J. Schult): "Mac-Anwender hatten bisher keine große Auswahl bei Multimedia-Enzyklopädien: entweder ein grottenschlechtes Kosmos Kompaktwissen, das dieses Jahr letztmalig erscheinen soll und sich dabei als Systhema Universallexikon tarnt. Oder ein Brockhaus in Text und Bild mit exzellenten Texten, aber flauer Medienausstattung. Die von Acclaim in Deutschland vertriebenen Britannica-Enzyklopädien stellen eine ausgezeichnete Alternative für den des Englischen Kundigen dar. Während früher nur Einfach-Britannicas auf dem Mac liefen, gilt dies nun für alle drei Versionen Student, Deluxe und Ultimate Reference Suite. Die Suite enthält dabei nicht nur alle 75 000 Artikel der 32 Britannica-Bände, sondern auch die 15 000 der Student Encyclopaedia, eines eigenen Schülerlexikons, das durch sein einfaches Englisch gerade für Nicht-Muttersprachler als Einstieg taugt. Wer es noch elementarer haben möchte, klickt sich zur Britannica Elementary Encyclopaedia, welche unter der gleichen Oberfläche wie die anderen Werke zugänglich ist. Schließlich umfasst die Suite einen Weltatlas sowie einsprachige Wörterbücher und Thesauri von Merriam-Webster in der Collegiate- und Student-Ausbaustufe mit allein 555 000 Definitionen, Synonymen und Antonymen. Wer viel in englischer Sprache recherchiert oder gar schreibt, leckt sich angesichts dieses Angebots (EUR 99,95) die Finger, zumal die Printausgabe gut 1600 Euro kostet. Die Texte sind einfach kolossal - allein das Inhaltsverzeichnis des Artikels Germany füllt sieben Bildschirmseiten. Schon die Inhalte aus den BritannicaBänden bieten mehr als doppelt so viel Text wie die rund tausend Euro kostende Brockhaus Enzyklopädie digital (c't 22/02, S. 38). Allein die 220 000 thematisch einsortierten Web-Links sind das Geld wert. Wer die 2,4 Gigabyte belegende Komplettinstallation wählt, muss sogar nie mehr die DVD (alternativ vier CD-ROMs) einlegen. Dieses Jahr muss sich niemand mehr mit dem Britannica-typischen Kuddelmuddel aus Lexikonartikeln und vielen, vielen Jahrbüchern herumschlagen - außer dem Basistext der drei Enzyklopädien sind 'nur' die zwei Jahrbücher 2001 und 2002 getrennt aufgeführt. Wer des Englischen mächtig ist, mag hier die gute Gelegenheit zum Kauf nutzen."

    Abstract
    This is the second part of two articles about reference linking in hybrid digital libraries. The first part, Frameworks for Linking described the current state-of-the-art and contrasted various approaches to the problem. It identified static and dynamic linking solutions, as well as open and closed linking frameworks. It also included an extensive bibliography. The second part describes our work at the University of Ghent to address these issues. SFX is a generic linking system that we have developed for our own needs, but its underlying concepts can be applied in a wide range of digital libraries. This is a description of the approach to the creation of extended services in a hybrid library environment that has been taken by the Library Automation team at the University of Ghent. The ongoing research has been grouped under the working title Special Effects (SFX). In order to explain the SFX-concepts in a comprehensive way, the discussion will start with a brief description of pre-SFX experiments. Thereafter, the basics of the SFX-approach are explained briefly, in combination with concrete implementation choices taken for the Elektron SFX-linking experiment. Elektron was the name of a modest digital library collaboration between the Universities of Ghent, Louvain and Antwerp.

    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
    The creation of services linking related information entities is an area that is attracting an ever increasing interest in the ongoing development of the World Wide Web in general, and of research-related information systems in particular. Currently, both practice and theory point at linking services as being a major domain for innovation enabled by digital communication of content. Publishers, subscription agents, researchers and libraries are all looking into ways to create added value by linking related information entities, as such presenting the information within a broader context estimated to be relevant to the users of the information. This is the first of two articles in D-Lib Magazine on this topic. This first part describes the current state-of-the-art and contrasts various approaches to the problem. It identifies static and dynamic linking solutions as well as open and closed linking frameworks. It also includes an extensive bibliography. The second part, SFX, a Generic Linking Solution describes a system that we have developed for linking in a hybrid working environment. The creation of services linking related information entities is an area that is attracting an ever increasing interest in the ongoing development of the World Wide Web in general, and of research-related information systems in particular. Although most writings on electronic scientific communication have touted other benefits, such as the increase in communication speed, the possibility to exchange multimedia content and the absence of limitations on the length of research papers, currently both practice and theory point at linking services as being a major opportunity for improved communication of content. Publishers, subscription agents, researchers and libraries are all looking into ways to create added-value by linking related information entities, as such presenting the information within a broader context estimated to be relevant to the users of the information.

    Abstract
    Since their inception in the early 1960s the strength and unique aspect of the ISI citation indexes has been their ability to illustrate the conceptual relationships between scholarly documents. When authors create reference lists for their papers, they make explicit links between their own, current work and the prior work of others. The exact nature of these links may not be expressed in the references themselves, and the motivation behind them may vary (this has been the subject of much discussion over the years), but the links embodied in references do exist. Over the past 30+ years, technology has allowed ISI to make the presentation of citation searching increasingly accessible to users of our products. Citation searching and link tracking moved from being rather cumbersome in print, to being direct and efficient (albeit non-intuitive) online, to being somewhat more user-friendly in CD format. But it is the confluence of the hypertext link and development of Web browsers that has enabled us to present to users a new form of citation product -- the Web of Science -- that is intuitive and makes citation indexing conceptually accessible. A cited reference search begins with a known, important (or at least relevant) document used as the search term. The search allows one to identify subsequent articles that have cited that document. This feature adds the dimension of prospective searching to the usual retrospective searching that all bibliographic indexes provide. Citation indexing is a prime example of a concept before its time - important enough to be used in the meantime by those sufficiently motivated, but just waiting for the right technology to come along to expand its use. While it was possible to follow citation links in earlier citation index formats, this required a level of effort on the part of users that was often just too much to ask of the casual user. In the citation indexes as presented in the Web of Science, the relationship between citing and cited documents is evident to users, and a click of the mouse is all it takes to follow a citation link. Citation connections are established between the published papers being indexed from the 8,000+ journals ISI covers and the items their reference lists contain during the data capture process. It is the standardized capture of each of the references included with these documents that enables us to provide the citation searching feature in all the citation index formats, as well as both internal and external links in the Web of Science.

    Abstract
    This is the third part of our papers about reference linking in a hybrid library environment. The first part described the state-of-the-art of reference linking and contrasted various approaches to the problem. It identified static and dynamic linking solutions, open and closed linking frameworks as well as just-in-case and just-in-time linking. The second part introduced SFX, a dynamic, just-in-time linking solution we built for our own purposes. However, we suggested that the underlying concepts were sufficiently generic to be applied in a wide range of digital libraries. In this third part we show how this has been demonstrated conclusively in the "SFX@Ghent & SFX@LANL" experiment. In this experiment, local as well as remote distributed information resources of the digital library collections of the Research Library of the Los Alamos National Laboratory and the University of Ghent Library have been used as starting points for SFX-links into other parts of the collections. The SFX-framework has further been generalized in order to achieve a technology that can easily be transferred from one digital library environment to another and that minimizes the overhead in making the distributed information services that make up those libraries interoperable with SFX. This third part starts with a presentation of the SFX problem statement in light of the recent discussions on reference linking. Next, it introduces the notion of global and local relevance of extended services as well as an architectural categorization of open linking frameworks, also referred to as frameworks that are supportive of selective resolution. Then, an in-depth description of the generalized SFX solution is given.

    Abstract
    The Wikipedia is a collaborative encyclopedia: anyone can contribute to its articles simply by clicking on an "edit'' button. The open nature of the Wikipedia has been key to its success, but has a flip side: if anyone can edit, how can readers know whether to trust its content? To help answer this question, we have developed a reputation system for Wikipedia authors, and a trust system for Wikipedia text. Authors gain reputation when their contributions are long-lived, and they lose reputation when their contributions are undone in short order. Each word in the Wikipedia is assigned a value of trust that depends on the reputation of its author, as well as on the reputation of the authors that subsequently revised the text where the word appears. To validate our algorithms, we show that reputation and trust have good predictive value: higher-reputation authors are more likely to give lasting contributions, and higher-trust text is less likely to be edited. The trust can be visualized via an intuitive coloring of the text background. The coloring provides an effective way of spotting attempts to tamper with Wikipedia information. A trust-colored version of the entire English Wikipedia can be browsed at http://trust.cse.ucsc.edu/
