A software ecosystem is the interaction of a set of actors on top of a common technological platform that results in a number of software solutions or services. Arguably, software ecosystems are gaining importance with the advent of, e.g., the Google Android, Apache, and Salesforce.com ecosystems. However, there exists no systematic overview of the research(More)
In this paper, we describe Kimura, an augmented office environment to support common multitasking practices. Previous systems, such as Rooms, limit users by constraining the interaction to the desktop monitor. In Kimura, we leverage interactive projected peripheral displays to support the perusal, manipulation and awareness of background activities.(More)
Modeling is important in object-oriented software development. Although a number of Computer Aided Software Engineering (CASE) tools are available, and even though some are technically advanced, few developers use them. This paper describes our attempt to examine the requirements needed to provide tool support for the development process, and describes and(More)
The health of a software ecosystem is an indication of how well the ecosystem is functioning. The measurement of health can point to issues that need to be addressed in the ecosystem and areas for the ecosystem to improve. However, the software ecosystem field lacks an applicable way to measure and evaluate health. In this work, we review the literature(More)

Combining existing services to create new pervasive computing services involves special design considerations, including context awareness, contingency management, device heterogeneity, and user empowerment. Service composition is a natural concept around which to structure pervasive systems and individuate parts of them that are suitable for contingency(More)
Self-management is one of the challenges for realizing Ambient Intelligence in pervasive computing. In this paper, we propose and present a semantic web based selfmanagement approach for a pervasive service middleware where dynamic context information is encoded in a set of self-management context ontologies. The proposed approach is justified from the(More)
An important characteristic of ubiquitous computing is that the computational services in our environment are envisioned to be far more interconnectable than today. This means it should be possible to combine them to suit the purpose at hand at any given time. However, given a particular combination of services, there are numerable combined behaviours that(More)
This paper describes experience obtained through a joint project between a university research group and a shipping company in developing a prototype for a global customer service system. The research group had no previous knowledge of the complex business of shipping, but succeeded in developing a prototype that more than fulfilled the expectations of the(More)
