Multi-Agent Systems (MAS) architectures are gaining popularity over traditional ones for building open, distributed, and evolving software required by today’s corporate IT applications such as eBusiness systems, web services or enterprise knowledge bases. Since the fundamental concepts of multi-agent systems are social and intentional rather than object, functional, or implementation-oriented, ...

The Unified Modeling Language (UML) currently proposes a mechanism to model recurrent design structures: the parameterized collaborations. The main goal of this mechanism is to model the structure of Design Patterns. This is an interesting feature because it can help designers to point out pattern application without spending time with intricate design details. Moreover, it can also help design...

This position paper was written for the CHI2000 Patterns Workshop, The Hague, 2–3 April, 2000. It is a revised and extended version of a paper for a patterns workshop of the British HCI Group in March 2000. It offers twelve statements outlining my position about patterns in human-computer interaction (HCI). The first, under “Roots”, suggest how HCI, unlike software engineering, can adapt the or...

This paper describes three object-oriented design patterns local serialization, global serialization and recovery and their integration to support atomic objects. The paper emphasizes the policies each pattern offers and the heterogeneity of policies resulting from their integration. The policies supported by the patterns include: pessimistic and optimistic serialization; static, dynamic and hy...

Design patterns have proven to be very useful for the design of object-oriented systems. The power of design patterns stems from their ability to provide generic solutions to reappearing problems that can be specialised for particular situations. The implementation of design patterns, however, has received only little attention and we have identified four problems associated with the implementa...

This article concerns the design of self-contained digital games for the life-long learning context. Although the potential of games for teaching and learning is undisputed, two main barriers hamper its wide introduction. First, the design of such games tends to be complex, laborious and costly. Second, the requirements for a sensible game do not necessarily coincide with the requirements for e...

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...

Detection of instances of design patterns is useful for the software maintenance. This paper proposes a new framework for the automated detection of instances of design patterns. The framework uses a reengineering tool to analyze C++ source codes. Prolog is used to induce instances of design patterns, the elemental design patterns are also used as a intermediate results for the final target (de...

The Worskhop on Ontology and Semantic Web Patterns (WOP2015, 6th edition) was held on October 11, 2015 in conjunction with the 14th International Semantic Web Conference in Bethlehem, PA, USA. At the workshop, the organizers conducted a discussion with the participants regarding the promises and obstacles of ontology design patterns (ODPs for short). This editorial reports on those discussions....
