A Notation and Framework for Dialog Flow Control in Web Applications
نویسندگان
چکیده
The usability of web applications today often suffers from the page-based medium’s lack of intrinsic support for hierarchical dialog sequences mirroring the parent-child relationships between dialog boxes in window-based user interfaces. For multi-channel applications, an additional challenge lies in reconciling the device-independent business logic with the device-specific interaction patterns necessitated by different clients’ input/output capabilities. We therefore present a graphical Dialog Flow Notation that allows the specification of nestable dialog sequences for different presentation channels. These specifications serve as input for a Dialog Control Framework that controls the dialog flows of complex web applications.

A Dialog Flow Notation for Web-based Applications
Increasingly, client-server applications are implemented as web-based applications with user interfaces consisting entirely of web pages or equivalent renderings on other presentation channels (e.g. mobile or speech-based devices). However, the page-based medium and the stateless pull communication impose restrictions on the user interface that often manifest themselves in unsatisfactory dialog...
متن کاملA Meta-Model for the Dialog Flow Notation
While the separation of presentation and application logic is widely practiced in web-based applications today, many do not cleanly separate application and dialog control logic, which leads to inflexible implementations especially when multiple presentation channels shall be served by the same application logic. We therefore present a notation for specifying the complete dialog flow of an appl...
متن کاملStateWebCharts: A Formal Description Technique Dedicated to Navigation Modelling of Web Applications
This paper presents StateWebCharts (SWC), a formal description technique based on statecharts for describing navigation on web applications. This notation extends the classical statecharts notation by adding more necessary concepts such as an appropriate semantics for states and transitions in a Web context, including notions like dialog initiative control and client and server activities. As w...
متن کاملModel-driven Construction of Workflow-based Web Applications with Domain-specific Languages
The requirements for Web applications concerning workflow execution, interaction, aesthetics, federation and Web service integration are steadily increasing. Considering their complexity, the development of these “rich workflow-based Web applications” requires a systematic approach taking key factors like strong user involvement and clear business objectives into account. To this end, we presen...
متن کاملMobile Business Processes
Today’s global markets demand global processes. Increasingly, these processes are not only distributed, but also contain mobile aspects. We discuss two challenges brought about by these mobile business processes: Firstly, the need to specify the distribution of processes across several sites, and secondly, the need to specify the dialog flows of the applications implementing those processes on ...
