“…The addition of input and output ports to task elements is elaborated in [13], aiming to support semi-automatic generation of user interfaces. Ports are used to explicitly define the data elements necessary to start task execution as well as to create output that can be consumed by following elements.…”

User centered design and development of interactive systems utilizes theoretically well-grounded, yet practical ways to capture user's goals and intentions. Task models are an established approach to break down a central objective into a set of hierarchical organized tasks. While task models achieve to provide a good overview of the overall system, they often lack detail necessary to (semi-) automatically generate user interfaces. Based on requirements derived from a comprehensive overview of existing task model extensions, improvements and development methods, an approach that integrates logical rules with task models is introduced. By means of practical examples it is shown, that the integration of rules enables advanced execution flows as well as leaner task models thus improving their practical value.

“…If such functions are to be used on the task level, they should take the form of a service to be implemented on the semantic level. Klug [15] introduced a task state and ports on tasks to exchange data to turn CTT model into executable task model. Data ports from the linguistic perspective are at the semantic level.…”

The linguistic perspective emphasizes the use of linguistic taxonomy to classify (partition) graphical user interface concepts and elements on several linguistic levels with clearly-defined interfaces between levels. This perspective is based on Nielsen's Virtual Protocol for Interaction that consists of several linguistic levels: goal, pragmatic (task), semantic, syntactical, lexical, alphabetical and physical.A linguistic modeling is modeling the graphical interface by abstracting each linguistic level. The aim of the linguistic modeling is to enhance the maintainability quality of the graphical user interface model as defined in ISO-25010:2011, by enhancing sub-qualities of modularity, analyzability and modifiability.Recent research reported on the linguistic perspective and the linguistic modeling requirements. In this paper, we elaborate more towards a linguistic modeling by modeling the task level; the high abstract level in the linguistic stack. Our contribution is an executable hierarchical task model that fulfils the specific needs towards linguistic modeling.

“…The main motivation behind their work is the formal validation of whether a concrete implementation of a UI is consistent with its design specification. Klug and Kangasharju [2005] propose a formalization for task models where a task is not regarded as an atomic entity (like in CTT) but has a complex lifecycle, modeled by a so-called task state machine. In van den Bergh [2007] entire task expressions are translated into state charts, including high-level tasks.…”

User Interface (UI) development methods are poorly integrated with standard software engineering practice. The differences in terms of artifacts involved, development philosophies, and lifecycles can often result in inconsistent system and UI specifications leading to duplication of effort and increased maintenance costs. To address such shortcomings, we propose an integrated development methodology for use case and task models. Use cases are generally used to capture functional requirements whereas task models specify the detailed user interactions with the UI. Our methodology can assist practitioners in developing software processes which allow these two kinds of artifacts to be developed in a codependent and integrated manner. We present our methodology, describe its semantic foundations along with a set of formal conformance relations, and introduce an automated verification tool.
