Overview
Preference database systems for dynamic context (Pre+Con)
1. Aims
Meanwhile search engines have become a great tool in lots of applications, in particular their embedding in Internet and E-Commerce. However it becomes increasingly clear that a further improvement of the effectiveness of search engines requires the systematic integration of the users´ personal interests and context knowledge. At the chair of Prof. Kießling, these research subjects were already started at a very early stage and in doing so the concept of 'preferences' has been playing the key role.
At present, context knowledge and users' preferences which are fine-tuned for personalized queries and decision support systems will be incorporated into the already existing preference framework by efficient algorithms. For instance, dynamically changing context is a main requirement in the area of mobile assistence systems, because new situations may arise from opportunities and hard constraints enforce the end of the actual situation by transforming it to a more adequate situation.
The efficient implementation of context-aware systems requires a powerful management system for context-sensitive or situative preferences. Thus, the system takes care of the actual situation, determines the adequate preferences and, gives personalized advice to the user by offering situation-adequate action plans. As an issue, highly complex preference queries are generated, which have to take into account even global hard restrictions opening an unknown research area.

Integrated Community Relationship Management (ICoReMa)
1. Aims
One of most important developments in the use of the Internet is to make passive users aware of the existence of online communities (OC) such as social networks, wikis or file sharing networks. OC develops an intensive social network by means of technical platforms. This phenomenon is of considerable and increasing economic importance. Above all, media and IT companies have responded to it with expensive takeover bids in order to adjust their business model to the new environmental requirements and to make them ready for the future. However, the current economic situation of the OC does not justify the high fees. The current developments remind us of the economic crisis caused by the dotcom bubble´s burst at the turn of the millennium. Investors speculate over high and sustainable profits. This is, of course, tied up with high risks so that especially OC needs an integrated yield and risk management. The aim of the research project is to develop a reference information structure in terms of a “master plan” for the evaluation and control of OC. This structure should help founders and users of OC through a company- wide and consistent data base to make profit and risk orientated decisions concerning the allocation of resources, in line with a value- orientated business management, and at the same time to fulfill regulatory conditions. So that theoretical findings can be put into practice, reference models for information systems with reference to community relationship management should be set up. These refer first of all to the planning and control systems of the business management. In addition, the information which the designed data base gives other target groups for controlling reasons should be analysed, and this information -in dynamic contexts- should be distributed with acceptable effort to target groups. The ultimate aim is to distinguish these reference models considering different types and stages of OC. Thus, a kind of master plan should be developed to implement correspondent information systems.
