Ubiquity offers opportunities in terms of time aware, location aware, device aware, and personalised services. Development of ubiquitous Web applications, however, turns out to be rather complex and thus requires appropriate methodological support. Existing methods for modelling Web applications only partially match the requirements resulting from their ubiquitous nature.This article aims at filling this gap by presenting a UML based framework for modelling ubiquitous Web applications, focussing on issues of adaptation modelling. It encompasses both, context modelling by providing a physical and a logical context model, and modelling the adaptation process per se. The latter is realised in terms of a rule model enabling monitoring of context changes and activation of corresponding adaptation operations. The separation of a Web application in a stable and context independent part on the one hand and a variable and context dependent part on the other hand supports reusability and locality of change. 2002-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/12291 Voice Business Bamberger, Rainer; König, Anne Phone Manager is a system that generates and manages speech dialogues, so-called call flows. With the help of a browser based interface the different components within a linguistic dialogue can be created in a task-specific and customer-specific way. Examples are the flow of speech prompts (previously recorded phrases), text-to-speech, automatic speech recognition, voice mails, fax on demand, direct connection to the call center or to separate operators, and many more. Additionally, the Phone Manager enables the combination of fixed telephone network, mobile services, data base and other computer based applications. The application can be integrated into virtually every technical infrastructure by compliance with the ECTF-standard. 2002-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/12301 Basisarchitekturen Web-basierter Informationssysteme Weitz, Wolfgang In the course of time, different concepts for the implementation of Web-based information systems have emerged. This article gives an overview over three common approaches and introduces Zope as an example of a modern object-oriented web application framework. 2002-01-01T00:00:00Z
