We attempt to validate the conceptual framework “Physics of Notation”(PoN) as a means for
analysing visual languages by applying it to UML Use Case Diagrams. We discover that the …

Practical experience suggests that usage and understanding of UML diagrams is greatly
affected by the quality of their layout. While existing research failed to provide conclusive …

We present a holistic approach for efficient execution of bags-of-tasks (BOTs) on multiple
grids, clusters, and volunteer computing grids virtualized as a single computing platform …

Domain-specific modeling has gained increased attention in industry and academia in
recent years leading to the emergence of numerous highly specialized, domain-specific …

A core aspect of diagrammatic process modeling is the visualization of the logical and
temporal order in which tasks are to be performed in a process. While conventions and …

UML activity diagrams and state machines are both used for modeling system behavior from
the user perspective and are frequently the basis for deriving system test cases. In practice …

We investigate model understanding, in particular, how the quality of the UML diagram
layout impacts cognitive load. We hypothesize that this w ill have a significant impact on the …

Context Metamodels are cornerstones of various metamodeling activities. Such activities
consist of, for instance, transforming models into code or comparing metamodels. These …

Context: The “Physics of Notations”(PoN) supports a systematic improvement of the
cognitive effectiveness of visual modelling languages. Problem: PoN focuses on the …

This poster presents the latest results from a very large eye tracking study (n= 29) that
explores how modelers read UML diagrams. We find that various factors like layout quality …
