- Abstract
- Although service-oriented architectures go a long way toward providing interoperability in distributed, heterogeneous environments, managing semantic differences in such environments remains a challenge. We give an overview of the issue of semantic interoperability (integration), provide a semantic characterization of services, and discuss the role of ontologies. Then we analyze four basic models of semantic interoperability that differ in respect to their mapping between service descriptions and ontologies and in respect to where the evaluation of the integration logic is performed. We also provide some guidelines for selecting one of the possible interoperability models.

- Abstract
- Das Problem der Wahrnehmung und Darstellung von Wahrheit durch die Medien führt zu vier zentralen Fragen: Wie viel Wahrheit gibt es in der Welt, über die Journalisten berichten müssen? Wie ermittelt oder recherchiert man diese Wahrheit? Wie trennt man die Spreu vom Weizen? Und wie geht man als Journalist mit dem um, was man als Wahrheit erkannt hat oder erkannt zu haben glaubt? Hier gibt es ganz offensichtlich eine Parallele zwischen Journalisten und Wissenschaftlern. Journalisten und Wissenschaftler brauchen erstens Hypothesen, zweitens geeignete Hypothesentests, drittens ein gutes Abgrenzungs-Kriterium und viertens Verfahren, um die erkannten Sachverhalte auf angemessene Weise für eine Kommunikation mit anderen zu repräsentieren, das heißt sie darzustellen. Es gibt zwei große Unterschiede zwischen Journalisten und Wissenschaftlern: Journalisten sind in der Regel auf raum-zeitlich begrenzte Aussagen aus, Wissenschaftler in der Regel auf raumzeitlich unbegrenzte Gesetze. Aber diese Unterschiede sind fließend, weil Wissenschaftler raum-zeitlich begrenzte Aussagen brauchen, um ihre All-Aussagen zu überprüfen, und Journalisten sich immer häufiger auf das Feld der allgemeinen Gesetzes-Aussagen wagen oder doch zumindest Kausalinterpretationen für soziale Phänomene anbieten. Der zweite Unterschied besteht darin, dass die Wissenschaft weitgehend professionalisiert ist (zumindest gilt dies uneingeschränkt für die Naturwissenschaften und die Medizin), was ihr relativ klare Abgrenzungs- und Güte-Kriterien beschert hat. Diese fehlen weitgehend im Journalismus.

- Abstract
- By the explosion of possibilities for a ubiquitous content production, the information overload problem reaches the level of complexity which cannot be managed by traditional modelling approaches anymore. Due to their pure syntactical nature traditional information retrieval approaches did not succeed in treating content itself (i.e. its meaning, and not its representation). This leads to a very low usefulness of the results of a retrieval process for a user's task at hand. In the last ten years ontologies have been emerged from an interesting conceptualisation paradigm to a very promising (semantic) modelling technology, especially in the context of the Semantic Web. From the information retrieval point of view, ontologies enable a machine-understandable form of content description, such that the retrieval process can be driven by the meaning of the content. However, the very ambiguous nature of the retrieval process in which a user, due to the unfamiliarity with the underlying repository and/or query syntax, just approximates his information need in a query, implies a necessity to include the user in the retrieval process more actively in order to close the gap between the meaning of the content and the meaning of a user's query (i.e. his information need). This thesis lays foundation for such an ontology-based interactive retrieval process, in which the retrieval system interacts with a user in order to conceptually interpret the meaning of his query, whereas the underlying domain ontology drives the conceptualisation process. In that way the retrieval process evolves from a query evaluation process into a highly interactive cooperation between a user and the retrieval system, in which the system tries to anticipate the user's information need and to deliver the relevant content proactively. Moreover, the notion of content relevance for a user's query evolves from a content dependent artefact to the multidimensional context-dependent structure, strongly influenced by the user's preferences. This cooperation process is realized as the so-called Librarian Agent Query Refinement Process. In order to clarify the impact of an ontology on the retrieval process (regarding its complexity and quality), a set of methods and tools for different levels of content and query formalisation is developed, ranging from pure ontology-based inferencing to keyword-based querying in which semantics automatically emerges from the results. Our evaluation studies have shown that the possibilities to conceptualize a user's information need in the right manner and to interpret the retrieval results accordingly are key issues for realizing much more meaningful information retrieval systems.

- Abstract
- Für Webseiten ist, wie für alle interaktiven Anwendungen vom einfachen Automaten bis zur komplexen Software, die Benutzerfreundlichkeit von zentraler Bedeutung. Allerdings wird eine sinnvolle Benutzung von Informationsangeboten im World Wide Web häufig durch "cooles Design" unnötig erschwert, weil zentrale Punkte der Benutzerfreundlichkeit (Usability) vernachlässigt werden. Durch Usability Evaluation kann die Benutzerfreundlichkeit von Webseiten und damit auch die Akzeptanz bei den Benutzern verbessert werden. Ziel ist die Gestaltung von ansprechenden benutzerfreundlichen Webangeboten, die den Benutzern einen effektiven und effizienten Dialog ermöglichen. Das Buch bietet eine praxisorientierte Einführung in die Web Usability Evaluation und beschreibt die Anwendung ihrer verschiedenen Methoden.

- Abstract
- This study investigated Simon's behavioral decisionmaking theories of bounded rationality and satisficing in relation to young people's decision making in the World Wide Web, and considered the role of personal preferences in Web-based decisions. It employed a qualitative research methodology involving group interviews with 22 adolescent females. Data analysis took the form of iterative pattern coding using QSR NUD*IST Vivo qualitative data analysis software. Data analysis revealed that the study participants did operate within the limits of bounded rationality. These limits took the form of time constraints, information overload, and physical constraints. Data analysis also uncovered two major satisficing behaviors-reduction and termination. Personal preference was found to play a major role in Web site evaluation in the areas of graphic/multimedia and subject content preferences. This study has related implications for Web site designers and for adult intermediaries who work with young people and the Web

- Abstract
- Mit sozialen Suchdiensten - wie z. B. Yahoo Clever, Lycos iQ oder Mister Wong - ist eine Ergänzung und teilweise sogar eine Konkurrenz zu den bisherigen Ansätzen in der Web-Suche entstanden. Während Google und Co. automatisch generierte Trefferlisten bieten, binden soziale Suchdienste die Anwender zu Generierung der Suchergebnisse in den Suchprozess ein. Vor diesem Hintergrund wird in diesem Buch der Frage nachgegangen, inwieweit soziale Suchdienste mit traditionellen Suchmaschinen konkurrieren oder diese qualitativ ergänzen können. Der vorliegende Band beleuchtet die hier aufgeworfene Fragestellung aus verschiedenen Perspektiven, um auf die Bedeutung von sozialen Suchdiensten zu schließen.

- "Google, so betont die größte Internet-Suchmaschine immer wieder, möchte die Informationen der Welt möglichst vielen Menschen zugänglich zu machen. Um das zu erreichen, entwickelten Larry Page und Sergey Brin, die die Firma im September 1998 gründeten, in einem Studentenwohnheim einen neuen Algorithmus für die Online-Suche. Das Unternehmen aus dem kalifornischen Mountain View ist aber auch eine Geldmaschine. Im zweiten Quartal dieses Jahres erhöhte Google den Umsatz im Jahresvergleich um 77 Prozent und den Nettoprofit noch stärker um 110 Prozent. Ende Juni zählten die Kalifornier rund um den Globus fast 8000 Beschäftigte und verfügten über flüssige Mittel von reichlich 9,8 Milliarden Dollar. Aktienkurs verfünffacht Der Geldsegen verdankt sich der OnlineWerbung. So können Firmen bei Google Anzeigen schalten, die zum Suchbegriff des Nutzers passen. Beispiel: Wer Mallorca in die Google-Maske tippt, sieht neben der Trefferliste auf der Google-Website Annoncen über Mallorca-Reisen oder Fincas auf der Insel. Darüberhinaus versorgt Google auch Betreiber anderer Web-Sites mit Werbeanzeigen. Damit nicht genug. Google plant, Werbung auch auf Handys zu senden. Reklame im Radio und Anzeigenverkauf in Printmedien stehen ebenfalls auf dem Programm. Als Google im August 2004 an die Börse ging, machten Experten den Erfolg der Aktie vor allem von der Entwicklung der Online-Werbung generell und der Fähigkeit von Google abhängig, möglichst viele Anzeigen an Werbetreibende zu verkaufen. Der Ausgabekurs betrug damals 85 Dollar. Am Tag nach Bekanntgabe der You Tube-Übernahme, die in Aktien bezahlt wird, startete das Google-Papier mit rund 432 Dollar. Doch es ging an der Börse nicht immer nur bergauf. So brach der Kurs im Februar massiv ein, weil Google die Gewinnschätzung von Analysten verfehlte. Und immer wieder bemängeln Börsianer, dass das Unternehmen fast, nur mit Werbung sein Geld verdient. Dabei hat Gaogle längst eine Menge mehr zu bieten, als Internet-Suche und -Reklame, auch wenn sich dies nicht sofort und direkt in Dollar und Cent auszahlt. Die Kalifornier brachten den E-MailDienst Gmail heraus, das soziale Netzwerk Orkut, die Geo-Software Google Earth, das Chatprogramm Talk, den FestplattenDurchsucher Desktop, die Surf-Ergänzung Toolbar, das Fotoarchiv Picasa und und und. All dies verschenkt das Unternehmen an die Nutzer - und hofft auf mehr Besucher auf seinen Webseiten und mehr Gelegenheiten für Werbung. In jüngerer Zeit folgten unter anderem Google-Video, ein Kalender im Internet und ein Online-Büroprogramm. Nutzer können mit Google nicht nur suchen, sondern auch Texte schreiben, Fotos tauschen oder Dateienspeichern. Erfolg und Expansion von Google wecken aber auch Sorgen. So warnen Datenschützer, dass Google Nutzerprofile erstellen und verkaufen könnte. Die Grünen bewerten die Dominanz einzelner Suchmaschinen - Google hat in Deutschland einen Marktanteil von 85 Prozent - kritisch. Sie befürchten, dass viele Informationen verborgen bleiben und und eine einheitliche "Such"-Meinung entsteht. Kritik hagelte es auch, als Google (Firmenmotto: "Tu nichts Böses") eine chinesische Web-Site startete und sich den Zensurbestimmungen Pekings unterwarf."

- "Die Suchmaschine Google gilt oft als der beste Weg, um schnell etwas im Internet zu finden. Das war einmal, behauptet Apostolos Gerasoulis, jetzt gebe es www.teoma. com. "Wir sind die nächste Generation der Suchmaschinen", verspricht der Mathematikprofessor. Die Web-Sites von Google und Teoma sind ähnlich aufgemacht. Beide bieten eine weitgehend weiße Startseite mit wenigen, klaren Farben. Beide Suchmaschinen benutzen bei ihrer Arbeit zur Analyse der Anfragen einen komplizierten Algorithmus. Teoma hält den eigenen Ansatz aber für besser, weil dabei das Internet in Gruppen von Online-Gemeinschaften unterteilt wird. Dies liefere bessere Ergebnisse und erlaube eine nützlichere Auswahl. Zu einem Suchbegriff erscheinen bei Teoma zuerst links oben die bezahlten Verweise, darunter dann' alle anderen gefundenen Web-Seiten. Rechts erscheinen Vorschläge zur Verfeinerung der Suchanfrage, darunter manchmal Links von "Experten und Enthusiasten". Diese qualifizierten Antworten sind eine der Stärken, mit denen Teoma wuchern möchte. Sie sind besonders für Anfänger nützlich, die nach allgemeinen Themen wie Afrika" oder "Fußball" suchen. Allerdings könnte dieser Ergebnisdienst Nutzer auch überfordern, gerade wenn sie an das einfache Google gewöhnt seien, kritsiert Rob Lancaster von der Yankee Group."

- Abstract
- Der Artikel betrachtet anhand einer Studie zum Benutzerverhalten bei der Online-Katalogrecherche den gegenwärtigen Stellenwert und das zukünftige Potential der Web-OPACs. Dabei werden zunächst die Ergebnisse einer quantitativen Logfile-Analyse sowie qualitativer Benutzertests erörtert, bevor aktuelle Entwicklungen der Webtechnologie, die unter den Schlagworten Web 2.0 und Web 3.0 propagiert werden, im Zusammenhang mit der Online-Recherche und der Entwicklung neuartiger Suchverfahren kurz diskutiert werden.

- Abstract
- Die Entstehung von Social Software ermöglicht es Nutzern, in großem Umfang im Netz zu publizieren. Bisher liegen aber nur wenige empirische Befunde zu funktionalen Eigenschaften sowie Qualitätsaspekten von Nutzerbeiträgen im Kontext von Informationsmanagement und Information Retrieval vor. Diese Arbeit diskutiert grundlegende Partizipationsformen, präsentiert empirische Studien über Social Tagging, Blogbeiträge sowie Relevanzbeurteilungen und entwickelt Design und Implementierung einer "sozialen" Informationsarchitektur für ein partizipatives Onlinehilfesystem.

- Abstract
- The scale of web site design has grown so that what was once comparable to decorating a room is now comparable to designing buildings or even cities. Designing sites so that people can find their way around is an ever-growing challenge as sites contain more and more information. In the past, Information Architecture for the World Wide Web has helped developers and designers establish consistent and usable structures for their sites and their information. This edition of the classic primer on web site design and navigation is updated with recent examples, new scenarios, and new information on best practices. Readers will learn how to present large volumes of information to visitors who need to find what they're looking for quickly. With topics that range from aesthetics to mechanics, this valuable book explains how to create interfaces that users can understand easily.
