Multimedia technologies are rapidly attracting more and more interest every day. The Internet as seen from the end user is one of the reasons for this phenomenon, but not the only one. Video on Demand is one of the buzzwords today, but its real availability to the general public is yet to come. Content providers - such as publishers, broadcasting companies, and audio/video production ?rms - must be able to archive and index their productions for later retrieval. This is a formidable task, even more so when the material to be sorted encompasses many di?erent types of several media and covers a time span of several years. In order for such a vast amount of data to be easily available, existing database design models and indexing methodologies have to be improved and re?ned. In addition, new techniques especially tailored to the various types of multimedia must be devised and evaluated. For archiving and trasmission, data compression is another issue that needs to be addressed. In many cases, it has been found that compression and indexing can be successfully integrated, since compressing the data by ?ltering out irrelevancy implies some degree of und- standing of the content structure.

These are the proceedings of the Fifth International Workshop on Cooperative Information Agents, held in Modena, Italy, September 6-8, 2001. Information agent technology has become one of the major key technologies for the Internet and the World Wide Web. It mainly emerged as a response to the challenges of cyberspace from both the technological and human user perspective. Development of information agents requires expertise from di?erent research disciplines such as Arti?cial Intelligence (AI), advanced databases and knowledge base systems, distributed information systems, information retrieval, and Human Computer Interaction (HCI). The ?fth international workshop on Cooperative Information Agents (CIA) continued the tradition by capturing the intrinsic interdisciplinary nature of the above research area by calling for contributions from di?erent research communities, and by promoting open and informative discussions on all related topics. In keeping with tradition, the workshop featured a sequence of regular and invited talks of excellence given by leading experts in the ?eld. This year the topics of the talks are mainly on the challenges of information agents in the upcoming age of ubiquitous and pervasive computing. These challenges are in particular due to the necessity of an e?cient utilization, evolution, and trust management of information agents for user-oriented information search, pro- sion, and visualization in networked computing environments with small, mobile, and embedded devices. A di?erent issue concerns the potential of agent-based support of massive distributed data warehousing worldwide.

Dieses Buch zeigt den Einfluss informationstechnischer Erfindungen und Innovationen, wie Radio, TV und Internet, auf die öffentliche Meinung sowie auf das politische Handeln. Diese Medien und die entsprechenden Medienpraktiken nehmen heute eine wichtige Rolle in den teils jungen Demokratien Europas und Nordamerikas ein. Damit wird das informationelle Vertrauen zur zentralen Frage der Politik. Weder der Begriff noch das Phänomen "Fake News" sind neu. Daher geht das Buch der Frage nach, welche Rolle die alten und nicht mehr ganz so neuen Medien bei der öffentlichen Meinungsbildung spielen und ob es strukturelle Veränderungen in diesem Bereich gibt. Denn: Wenn wir die Entstehung der öffentlichen Meinung verstehen wollen, müssen wir uns auf den Boulevard begeben, auf die sprichwörtliche Straße, auf den Bürgersteig.Der transdisziplinäre Blick in Ullrichs Buch erlaubt es dem Leser, die eingesetzte Technik im gesellschaftlichen Kontext zu verstehen. Technische Sachverhalte werden einfach, aber dennoch detailliert in Bezug zu politischen und sozialen Themen gesetzt. Das Sachbuch spricht damit jeden an, der sich für neue Medien, Ethik und Politik interessiert.Der AutorStefan Ullrich ist promovierter Informatiker und Philosoph. Er leitet die Forschungsgruppe "Verantwortung und das Internet der Dinge" am Weizenbaum-Institut für die vernetzte Gesellschaft in Berlin. Seit 2011 ist er als Sprecher der Fachgruppe "Informatik und Ethik" der Gesellschaft für Informatik (GI e. V.) aktiv.
