Over the last few years the number of services for mobile devices that are connected to the internet via UMTS or wireless 802.11 hotspots has grown tremendously. However, only a small proportion of these applications or services, has been successfully adopted and none has yet turned out to be the hoped-for killer application. We believe that context-sensitive service discovery is the key success factor for mobile applications and could have the same impact and level of success as search engines on desktop computers. Keyword-based searches using typical search engines or portals for browsing services with a mobile device often do not provide satisfying results within a reasonable period of time and they are cumbersome to use because of the restricted and limited input capabilities of mobile devices. In this paper we present a hybrid service discovery approach that uses context information to reduce human device interaction and delivers precise, personalized search results for service requests in a changing environment.
