Today, online communities in the World Wide Web become increasingly interactive and networked. Web 2.0 technologies provide a multitude of platforms, such as blogs, wikis, and forums where for example consumers can disseminate data about products and manufacturers. This data provides an abundance of information on personal experiences and opinions which are extremely relevant for companies and sales...
Web 2.0 platforms change the collaboration within online communities. A new way of organizing and opinion exchanging derives from increased social interactions and networking among community members. These members join together in self-organizing groups where opinions are forming by social swarming. Explaining and predicting the evolutionary process of opinion formation by social swarming is not only...
The Internet is increasingly changing from a medium of distribution to a platform of interaction. Customer discussions in Web 2.0 are a valuable source of information for companies. An opinion mining approach is presented which allows an auto-mated extraction, aggregation, and analysis of customer opinions on products by using text mining. Thus, strengths and weaknesses judged by customers can be...
A technical transaction support environment to be used in the field of e-government is introduced. A transaction platform provides electronic services offered by public administration. Citizens can access these services by using smartcards and perform transactions as self-service. A case study focuses on automating enquiries previously handled by the registration office. It shows a sample implementation...
Improving the efficiency of business processes through automation is limited by the various manual and actor specific tasks. Even if no precise specifications of individual tasks are available, it is necessary to support the course of business processes appropriately. As an essential part of all support systems, a flexible escalation management component must be able to inform the user about imminent...
An increasing number of users of opinion forums provide us with rich sources of data about customer opinions. Several fields of research deal with the analysis of qualitative or quantitative data.

Modelling and simulation are commonly used to explore the dynamic behaviour of complex technical and socioeconomic systems. An approach using system dynamics models to describe and predict dynamic collaboration structures within and between companies is introduced. System dynamics is based on equation based modelling and continuous simulation and has been applied successfully to support strategic...
Monitoring and coordination of planning processes requires a very flexible support by information systems. Due to the high amount of activities conducted in parallel as well as numerous interdependencies between inputs and outputs of every process step, present coordination concepts result in information deficits during process execution. In cooperation with an industry partner an agent-based information...
In B2B (business-to-business) e-commerce companies depend eminently on the punctual fulfillment of orders given to their suppliers. It is a very time consuming and costly task to observe every order in a way that bad events can be detected instantaneously. This is especially true if there are many suppliers providing various parts and you also have to check the supply of the suppliers etc. So called...
Peak load management is a typical application that relies on dynamic sourcing of grid services and is characterized by instantaneous, dynamic needs that must be served on short notice. Therefore, decision support by autonomous systems is not an option but a must on a grid market. To achieve efficient resource utilization by contract customization without neutralizing its welfare effects by excessive...
Existing business process support systems focus on execution of highly structured business processes which are represented in a formal modeling notation. These systems fail, if processes are weakly structured or if process changes have to be considered during execution. Therefore, an information logistics architecture is proposed to support business processes, especially those which rely on informational...
The concept of a virtual lecture theatre has been realised at the Faculty of Economics, Business Administration and Social Sciences in Nuremberg since 1995. Interdisciplinary courses are being held for local students at one faculty and are interactively broadcast for students joining in from remote locations. Various demands concerning the teleteaching environment have to be met in order to enable...
