Collaborative networked organizations (CNOs) are complex entities whose proper understanding, design, implementation, and management require the integration of different modeling perspectives. A large number of modeling tools and theories that have been developed in other disciplines have a potential applicability in this domain. Therefore, an identification of the most promising approaches is ...

The Language-action perspective (LAP) provides an alternative foundation for analyzing and designing effective information systems. The fundamental principle of the LAP approach is people perform actions through communication; therefore, the role of information systems is to support such communications among people to achieve business goals. Basing on linguistic and communicative theories, the ...

The Abstract State Machine (ASM) theory is a way to specify algorithms, applications and systems in a formal model. Recent ASM languages and tools address either the translation of ASM specifications to a specific target programming language or aim at the execution in a specific environment. In this work-in-progress paper we outline a modelbased transformation approach supporting (1) the specif...

Many types of pairwise interaction take the form of a fixed set of nodes with edges that appear and disappear over time. In the case of discrete-time evolution, the resulting evolving network may be represented by a time-ordered sequence of adjacency matrices. We consider here the issue of representing the system as a single, higher dimensional block matrix, built from the individual time-slice...

Weblogs are important new components of the Internet. They provide individual users with an easy way to publish online and others to comment on these views. Furthermore, there is a suite of secondary applications that allow weblogs to be linked, searched, and navigated. Although originally intended for individual use, in practice weblogs increasingly appear to facilitate distributed conversatio...

Strong indications of perspective can often come from collocations of arbitrary length; for example, someone writing get the government out of my X is typically expressing a conservative rather than progressive viewpoint. However, going beyond unigram or bigram features in perspective classification gives rise to problems of data sparsity. We address this problem using nonparametric Bayesian mo...

Cooperative documentation systems have been developed in healthcare to support cooperation between different professionals. However, the systems have been developed on an intuitive basis which means that occurring communication problems can pose a serious threat to smooth and effective cooperation. This paper considers the question how a Language-Action Perspective can help in the development o...

In the current literature on service-oriented computing, the relationship between services and web-services is not always clear. Much research, notably in the area of service representation, discovery and composition, claims to address services whereas they actually apply to web-services. In this paper, we use insights from Language/Action Perspective and from value modeling to define services ...

Spatial memory has been recognized as an important factor in efficient human-computer interaction. However, most previous studies are limited to very simple depth cues and 2D displays. We present a study investigating the effects of head-coupled perspective, stereoscopy and simple landmarks on spatial memory by measuring performance and accuracy in a memory game. Our results indicate that head-...

We argue that the recent move to service-oriented computing as a dominant paradigm presents an opportunity to the Language-Action community. Service-oriented computing emphasizes communication among independent services as the basic composition unit for application development. This view maps well against the basic premise underlying the Language-Action perspective that the basic unit of a soft...
