The wide-spread adoption of process-aware information systems has resulted in a bulk of computerized information about real-world processes. This data can be utilized for process performance analysis as well as for process improvement. In this context process mining offers promising perspectives. So far, existing mining techniques have been applied to operational processes, i.e., knowledge is e...

Brewka and Eiter’s nonmonotonic multi-context systems is an elegant knowledge representation framework to model heterogeneous and nonmonotonic multiple contexts. Belief change is a central problem in knowledge representation and reasoning. In the paper we follow the classical AGM approach to investigate belief change in multi-context systems. Specifically, we semantically formulate the AGM post...

One of the most exciting promises of a complex systems perspective for learning and education, well captured in Jacobson and Wilensky’s target article, is to provide a unifying force to bring together increasingly fragmented scientific communities. The day when scientists have time to read broadly across chemistry, biology, physics, and social sciences is long gone. Journals, conferences, and a...

We propose maximizing the change of thermodynamic entropy in order to obtain the probability distributions for nonequilibrium systems in steady or stationary evolution. Arguments are forwarded to support this approach. A path information leading to Kolmogorov-Sinai entropy is defined for an ensemble of possible trajectories between two points in phase space. It is shown that the maximization of...

As systems become larger, more complex, and operate for longer periods of time, some change within the system often becomes inevitable. Particularly in systems of systems, with diverse stakeholders, evolutionary development and managerial independence, it is not unusual for constituent systems to change in form or the way they operate. Changeability, the ability of a system to change, is often ...

Managing of and reasoning about dynamic processes is a central aspect of much activity in the office. WC present a brief dcscrintion of our view of office systems and why change is of central importance in the office. A description system used to describe the structure of the office and office activity is discussed. A viewpoint mechanism within the description system is prcscntcd and we discuss...

An argumentation system can undergo changes (addition or removal of arguments/interactions), particularly in multiagent systems. In this paper, we are interested in dynamics of abstract bipolar argumentation systems, i.e. argumentation systems using two kinds of interaction: attacks and supports. We propose change characterizations that use and extend previous results defined in the case of Dun...

European Journal of Information Systems (2007) 16, 193–195. doi:10.1057/palgrave.ejis.3000681 In this editorial, I am going to discuss the challenges as I see them to Information Systems (IS). The European Journal of Information Systems has decided to publish a debate on these challenges, starting in its next issue when Richard Baskerville (incoming Editor-in-Chief for the journal in 2008) and ...

The Introduction of anything related to systems architecting, such as methods or techniques, systems thinking, or role and task requires a change management strategy. We will discuss how to introduce these changes into an organization. Distribution This article or presentation is written as part of the Gaudí project. The Gaudí project philosophy is to improve by obtaining frequent feedback. Fre...

1 Motivation and Scope of Study There has been a lot of recent interest in the integration of data from a large number of sources. This has surfaced mainly due to the growing popularity of the Web.The Web in itself can be viewed as a large distributed database which is composed of hundreds of thousands of nodes.Even though there have been reasonable solutions for building DDBs,these have been s...
