Abstract. This pattern language describes how to reverse engineer an object-oriented software system. Since the only way to achieve a truly reusable object-oriented design is recognised to be iterative development, reverse engineering is indeed an essential facet of any object-oriented development process. The pattern language itself covers the different phases one encounters when reverse engin...

High-level usability principles (e.g. “Familiarity”) are difficult to apply to specific projects, and style guides providing more detailed instructions are often misinterpreted and inaccessible. An approach to usability based on design patterns enables designers to learn how certain recurring problems can be solved according to high-level principles. This paper summarises a review of the desira...

Online auctions are gaining popularity as they provide an excellent means of selling goods. Their advantages include: reducing transaction costs, selling goods that are difficult to sell through the ordinary market channels, and increasing the circle of potential customers. This paper presents a pattern language for the Web auction application domain. The pattern language has ten analysis patte...

Patterns are classically used to effectively capture large, complex bodies of information and knowledge. This paper outlines the current state of systems engineering (SE) pattern application and proposes improvements and additions to SE patterns, pattern maps and pattern languages. A pattern is a solution of a specific problem placed in a specific context. A pattern language is a collection of ...

Modeling human computer interactions as dialog, while originating in voice user interfaces, is becoming increasingly important for multimodal systems. Di erent approaches with regard to formalizing and managing dialogues exist with their speci c strength and weaknesses. In this paper, we present existing dialogue management techniques as patterns to give a basis for decision support when develo...

After an object-oriented framework for micro-processor based fire alarm systems had been implemented and the first instantiated system had reached product status an effort was undertaken to clearly document the architecture embedded in the framework. The result of this effort was a small pattern language which is presented in this paper. Important patterns in this language are the Point pattern...
