The development of service-oriented applications has reached a point where more specifications are needed to enable holistic transparent service-management. A three-schema-architecture for design of servicebase-management-systems according to the ANSI/SPARC-model for database design is proposed in this paper. The conceptual schema of the proposed architecture decribes the servicebase, what prov...

Many psychologists collect multitrait-multimethod (MTMM) data to assess the convergent and discriminant validity of psychological measures. In order to choose the most appropriate model, the types of methods applied have to be considered. It is shown how the combination of interchangeable and structurally different raters can be analyzed with an extension of the correlated trait-correlated meth...

I study creation of multiagent organizations via an automated computational process. My organizational design problem frames design decisions in terms of the quantitative impact that an organization is expected to have on the agents’ reasoning and behaviors. I develop techniques for efficiently solving this problem via incremental search of the organizational design space, and extend my organiz...

− We provide a reformulation of Cocke−Younger−Kasami’s algorithm for recognizing context-free languages in which there are no references either to indices of table entries or to the length of the input string. Some top-down analogues of this functional approach are discussed as well.

This paper presents a tool to help software design in the development process. This software prototype will promote further development of Problem Frames framework (PF) and drive it to maturity, i.e., from theoretical research to practical applications.

When designing and implementing real world ambient intelligent systems we are in need of applicable information systems engineering methods. The tools we find in the intelligent systems area focus on the knowledge engineering parts, whereas traditional software engineering techniques are usually not designed with the peculiarities of intelligent systems design in mind. This holds in particular ...

While classical software engineering dictums separate the development of a system’s requirements from its design, practice has largely shown this to be either impractical or naive. Much of the design of large software-dependent systems comes from prior systems, and that knowledge affects the requirements for new systems. Even if prior systems do not directly determine new system’s requirements,...

In two studies, we investigated the ability of a variety of structural and temporal measures computed from a web navigation path to predict lostness and task success. The user’s task was to find requested target information on specified websites. The web navigation measures were based on counts of visits to web pages and other statistical properties of the web usage graph (such as compactness, ...
