Hou, T., & Chapman, P. (2019). Antipattern comprehension dataset. [Dataset]. https://doi.org/10.17869/enu.2019.2275783

Comprehension of justifications is known to be difficult for even experienced ontology engineers, and much more so for other stakeholders. In the paper associated with this data set, we presented two methods for displaying justifications using concep... Read More about Antipattern comprehension dataset.

Visualization has been widely used for the representation of ontologies. However, to the best of our knowledge, visualization has been little employed in ontology debugging. Effective ontology debugging is crucial for engineers and domain experts to... Read More about Debugging Ontologies Dataset.

Antipattern comprehension: an empirical evaluation (2016)
Presentation / Conference Contribution
Hou, T., Chapman, P., & Blake, A. (2016, July). Antipattern comprehension: an empirical evaluation. Presented at 9th International Conference on Formal Ontology in Information Systems

Comprehension of justifications is known to be difficult for even experienced ontology engineers, and much more so for other stakeholders. In this paper, we present two methods for displaying justifications using concept diagrams: using multiple conc... Read More about Antipattern comprehension: an empirical evaluation.

Measuring perceived clutter in concept diagrams (2016)
Presentation / Conference Contribution

Clutter in a diagram can be broadly defined as how visually complex the diagram is. It may be that different users perceive clutter in different ways, however. Moreover, it has been shown that, for certain types of diagrams and tasks, an increase in... Read More about Measuring perceived clutter in concept diagrams.

Visualizing Sets with Linear Diagrams. (2015)
Journal Article

This paper presents the first design principles that optimize the visualization of sets using linear diagrams.
These principles are justified through empirical studies that evaluate the impact of graphical features on task
performance. Linear diagr... Read More about Visualizing Sets with Linear Diagrams..

Evaluating the Impact of Clutter in Euler Diagrams. (2014)
Presentation / Conference Contribution
Alqadah, M., Stapleton, G., Howse, J., & Chapman, P. (2014, July). Evaluating the Impact of Clutter in Euler Diagrams

Euler diagrams, used to visualize data and as a basis for visual languages, are an effective representation of information, but they can become cluttered. Previous research established a measure of Euler diagram clutter, empirically shown to correspo... Read More about Evaluating the Impact of Clutter in Euler Diagrams..

Visualizing Sets: An Empirical Comparison of Diagram Types. (2014)
Presentation / Conference Contribution

There are a range of diagram types that can be used to visualize
sets. However, there is a significant lack of insight into which is the
most effective visualization. To address this knowledge gap, this paper empirically evaluates four diagram type... Read More about Visualizing Sets: An Empirical Comparison of Diagram Types..
