Currently engineering efficient and successful event-driven applications based on the emerging Complex Event Processing (CEP) technology, is a laborious trial and error process. The proposed CEP design pattern approach should support CEP engineers in their design decisions for building robust and efficient CEP solutions with well understood tradeoffs and should enable an interdisciplinary and e...

Generic Ontologies are introduced in GDOL, an extension of DOL, the Distributed Ontology, Modeling and Specification Language, and implemented using Hets, the Heterogeneous Tool Set framework. Parameters such as classes, properties, individuals, or whole ontologies may be instantiated with arguments in a host ontology. A Generic Ontology Design Pattern, GODP, defined in GDOL, embodies an ontolo...

Periodic refactoring of a large source code often becomes a necessity especially for long-lived projects. In order to increase maintainability and extensibility of such projects, design pattern based refactoring can be seen as an emerging alternative. Manual inspection of source code to find candidate spots where patterns can be introduced is time consuming. Therefore automated tools can help i...

In usual software engineering approaches, object oriented modeling with the UML is meanwhile state of the art. In this area, object orientation has been extremely beneficial: object oriented modeling allows to structure the application data in a way that eases maintenance and that allows to distribute the responsibility for certain functionality among the participating objects or components. Fi...

We put forward initial results on lightweight phase-based control for dialogue systems as a test case of evolutionary development of such systems. A new design pattern for generalized phase-based processing is presented. A phase-based view of top-level control for dialogue systems is suggested in terms of the new pattern. The work verifies the generality of a previously reported development met...

A university’s institutional repository (IR) contains the intellectual output of its faculty, staff and students. Its content is extensive and heterogenous, which complicates data aggregation and discovery tasks. To address these challenges, we propose the use of a conceptual ontology design pattern to model information for the IR domain which is general enough to be reused across different IR ...

Design patterns are considered as means to capture and communicate already proven and matured object-oriented design so that building reusable object-oriented software does not always have to start from scratch. There exists no standardization of the term design pattern in the realm of object-oriented software development. This paper makes an effort to define this vague term by giving an overvi...

This paper presents a role model implementation, JAWIRO (JAva WIth ROles), which enhances Java with role support. After a brief introduction to role models and the capabilities of JAWIRO, the paper proceeds to a comparison of our model with another role model and a design pattern for implementing roles. These three approaches are compared on the basis of their abilities and performances. It is ...

We show how a domain and language independent design pattern, defined as networks of tasks and goals, can be used to formally specify the transfer of responsibility and accountability when tasks are delegated in healthcare teams. The pattern is general enough to be applied unchanged across a broad range of different healthcare situations.

This paper proposes a model for designing games around Artificial Intelligence (AI). AI-based games put AI in the foreground of the player experience rather than in a supporting role as is often the case in many commercial games. We analyze the use of AI in a number of existing games and identify design patterns for AI in games. We propose a generative ideation technique to combine a design pat...
