Abstract. Various ontology visualization techniques have been developed over the years, offering essential interfaces to users for browsing and interacting with ontologies, in an effort to assist with ontology understanding. Yet few studies have focused on evaluating the usability of existing ontology visualization techniques. This paper presents an eye-tracking user study that evaluates two commonly used ontology visualization techniques, namely, indented list and graph. The eye-tracking experiment and analysis presented in this paper complements the set of existing evaluation protocols for ontology visualization. In addition, the results found from this study contribute to a greater understanding of the strengths and weaknesses of the two visualization techniques, and in particular, how and why one is more effective than the other. Based on approximately 500MB of eye movement data containing around 30 million rows of gaze data generated by a Tobii eye tracker, we found evidence suggesting indented lists are more efficient at supporting information searches and graphs are more efficient at supporting information processing.

“…A number of 'hybrid' solutions also exist, such as Jambalaya [10] and Knoocks [11], which attempt to combine the different strengths of containment-based and node-link approaches in an integrated framework, by providing both alternative visualizations as well as hybrid, integrated views of the two paradigms.…”

“…For the tasks we used a smaller version of the SUMO ontology, compared to the one referred to in section 4, which comprises 630 classes 10 . SUMO was chosen because, as an upper-level ontology, it is reasonable to expect most people to have familiarity with the notions it covers, in contrast with highly specialized ontologies in technical domains.…”

Abstract. Observational studies in the literature have highlighted low levels of user satisfaction in relation to the support for ontology visualization and exploration provided by current ontology engineering tools. These issues are particularly problematic for non-expert users, who rely on effective tool support to abstract from representational details and to be able to make sense of the contents and the structure of ontologies. To address these issues, we have developed a novel solution for visualizing and navigating ontologies, KC-Viz, which exploits an empirically-validated ontology summarization method, both to provide concise views of large ontologies, and also to support a 'middle-out' ontology navigation approach, starting from the most information-rich nodes (key concepts). In this paper we present the main features of KC-Viz and also discuss the encouraging results derived from a preliminary empirical evaluation, which suggest that the use of KC-Viz provides performance advantages to users tackling realistic browsing and visualization tasks. Supplementary data gathered through questionnaires also convey additional interesting findings, including evidence that prior experience in ontology engineering affects not just objective performance in ontology engineering tasks but also subjective views on the usability of ontology engineering tools.

“…A combination of node-link approaches and container approaches is another possibility to visualize ontologies. For example, Jambalaya (Storey et al, 2010), which is also a plug-in for Protégé, provides different views with different visualization techniques. In addition to views which represent the relationships between the concepts purely as node-link representation, one view provides the adapted treemap approach of (Shneiderman, 1992) which allows users to rapidly jump between classes or instances.…”

Ontologies were becoming popular in various communities and disciplines over the past few years. The reason for their popularity is that they allow to specify concepts and their interconnections of a domain which are understandable by computers and by people. However without visualizations, ontologies-especially large ones-would be hard to comprehend by users. Visualizations are essential because they make ontologies with their structure more manageable. Furthermore, visualization tools are helpful to analyze the interconnections between concepts. For an effective usage of such visualization tools, it is necessary that the design is easy to understand, provides a good overview about the structure and allows fast access to detail information. Furthermore, it is necessary to consider the domain for which the ontology is developed along with its users and their needs. This paper presents the development process of Knoocks-a visualization tool for OWL Lite ontologies-where users were already involved during the process to improve the usability of the tool. Moreover, the presented case study underlines the importance of repeated usability evaluations during the development process to identify weak points of the design and missing features which are relevant for the intended users.
