We introduce the general user model ontology GUMO for the uniform interpretation of distributed user models in intelligent semantic web enriched environments. We discuss design decisions, show the relation to the user model markup language USERML and present the integration of ubiquitous applications with the u2m.org user model service.
Fibronectin (FN) is secreted as a disulfide-bonded FN dimer. Each subunit contains three types of repeating modules: FN-I, FN-II, and FN-III. The interactions of alpha5beta1 or alphav integrins with the RGD motif of FN-III repeat 10 (FN-III10) are considered an essential step in the assembly of FN fibrils. To test this hypothesis in vivo, we replaced the(More)
We revisit the top-level ontology Gumo for the uniform management of user and context models in a semantic web environment. We discuss design decisions, while putting the focus on ontological issues. The structural integration into user model servers, especially into the U2M-UserModel&ContextService, is also presented. We show ubiquitous applications using(More)
We present a new architecture for decentralized user modeling and briefly discuss the user model markup language USERML, the general user model ontology GUMO for the uniform interpretation of decentralized user models, and the integration of ubiquitous applications with the u2m.org user model service. The motivation is that ubiquitous evaluation of user(More)
In this chapter we discuss various aspects of adaptive mobile guide applications. After having motivated the need for web based mobile applications, we will discuss technologies that are needed to enable adaptive mobile web applications, including not only positioning technologies but also sensor technologies needed to determine additional information on(More)
We use semantic web technology to utilize the world wide web for a large-scale ubiquitous hybrid location model, in order to achieve shareability and extensibility. Our intention is to model location and user characteristics, in order to realize location aware applications with focus on situated user interaction and pedestrian navigation. We present the(More)
We present a distributed service to model and control contextual information in mobile and ubiquitous computing environments. We describe the general user model and context ontology GUMO for the uniform interpretation of distributed situational information in intelligent semantic web enriched environments. Furthermore, we present the relation to the user(More)
