Table A1 summarizes the various characteristics of the synthetic models used in the experiments, including the number of event types, the size of the state space, whether a challenging construct is contained (loops, duplicates, nonlocal choice, and concurrency), and the entropy of the process defined by the model (estimated based on a sample of size(More)
Distributed construction of conceptual models may lead to a set of problems when these models are to be compared or integrated. Different kinds of comparison conflicts are known (e.g. naming conflicts or structural conflicts), the resolution of which is subject of different approaches. However, the expost resolution of naming conflicts raises subsequent(More)
During the last years the optimisation of business processes has gained more and more importance in the context of modernising public administrations. In line with the concept of electronic government (eGovernment) citizens demand not only an improved design of internet sites, but also the creation of real added value to administrational services. In(More)
Conceptual modeling is an established instrument in the knowledge engineering process. However, a precondition for the usability of conceptual models is not only their syntactic correctness but also their semantic comparability. Assuring comparability is quite challenging especially when models are developed by different persons. Empirical studies show that(More)
The adaptation of conceptual information models to specific requirements has been discussed for several years. Especially, different approaches to information model configuration have reached certain popularity. Nevertheless, up to now, model configuration is not supported sufficiently by recent modeling tools. In this paper, we present the implementation(More)
