Personalizing the Usage of Complex Services

Granting access to functionality via services is a rather big part of the modern information technologies market. At the same time, the growing functionality of services makes their use more and more complex for the end user. This is especially pronounced when using mobile devices, such as a handheld computers (PDA) or smartphones with limited I/O-capabilities. In this paper we investigate how users can be supported in such environments by personalization of service interaction. We also discuss various aspects of how user priorities can be formalised and integrated into the service request. Such an approach allows for the reduction of the laboriousness of service usage by enabling its automation. 1
