Its main components are the recording and management of multimedia data (i.e. image, video and text data) in a database system, semi-automatical analysis tools for images and videos, and a graphical user interface (GUI) integrating all tools and components applied in media research. 2002-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/12272 Unified Messaging in großen Unternehmen Wohlfeil, Stefan; Voelz, Dirk This paper is about Unified Messaging in large enterprises. Messaging in enterprises is usually characterised by infrastructures for telephony and E-Mail already being in place. Enterprises are often reluctant to replace existing systems simply in order to enhance functionality. This is due to the fact that large investments had already been made and companies are expecting a return on investment. p]Unified Messaging integrates different communication means. It supports employees who travel a lot and others who receive many messages of different types. This paper begins with a description of Unified Messaging functions. Then we describe typical Unified Messaging architectures. One of our main conclusions is that choosing well designed communication interfaces (usually by employing standard protocols) is more important than simply choosing a good Unified Messaging product. In section 3 we describe a Unified Messaging architecture suitable for large enterprises. This architecture fits well into already existing architectures. We conclude with an estimation of investment costs and operation costs for such an architecture. 2002-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/12273 WI — Dissertationen 2002-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/12268 Kooperierende intelligente Softwareagenten Kirn, Stefan This paper introduces to the reader the field of cooperating intelligent software agents. It first reviews the historical roots of Distributed AI, and the main concepts that have been developed in that field since the end of the seventies, and on which today’s agent technology is based upon. The paper then concentrates on the modeling of agents. Starting with a terminological discussion of what agents are, and with an example the main characteristics of cooperating intelligent agents are presented, formalized, and discussed. Based upon this the paper proceeds to issues that are relevant to multiagent systems: coordination, communication, and standardization. The paper concludes with a sum-up of the main results, and an extensive bibliography. 2002-01-01T00:00:00Z
