“…An approach to addressing the issue of providing high level overviews of hierarchical structures focuses on maximizing the amount of information on display, through space-filling solutions, such as those provided by treemaps [8]. Treemaps have proved to be a very successful and influential visualization method, used not just to represent conceptual hierarchies but also to visualize information in several mainstream sectors, including news, politics, stock market, sport, etc.…”

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.

Abstract. Recognized as great works of world literature, Shakespeare's poems and plays have been translated into dozens of languages for over 300 years. Also, there are many re-translations into the same language, for example, there are more than 60 translations of Othello into German. Every translation is a different interpretation of the play. These large quantities of translations reflect changing culture and express individual thought by the authors. They demonstrate wide connections between different world regions today, and reveal a retrospective view of their cultural, intercultural, and linguistic histories. Researchers from Arts and Humanities at Swansea University are collecting a large number of translations of William Shakespeare's Othello. In this paper, we have developed an interactive visualization system to present, analyze and explore the variations among these different translations. Our system is composed of two parts: the structureaware Treemap for document selection and meta data analysis, and Focus + Context parallel coordinates for in-depth document comparison and exploration. In particular, we want to learn more about which content varies highly with each translation, and which content remains stable. We also want to form hypotheses as to the implications behind these variations. Our visualization is evaluated by the domain experts from Arts and Humanities.

“…The taxa in a study are listed on the article web page. In order to convey a gestalt sense of what an article is about, I use a treemap [28] to display a set of images of the taxa in the article. The size of each cell in the treemap is proportional to the number of taxa in that group (typically a genus).…”

This paper describes my entry in the Elsevier Grand Challenge "Knowledge Enhancement in the Life Sciences" contest. The entry takes a collection of fulltext issues of Molecular Phylogenetics and Evolution as the starting point, then extracts citation links to both papers and data, such as Genbank sequences and specimens, together with geotagged localities, and builds a "web" of objects linked by typed relationships. Each object (such as a publication, a sequence, a specimen, a taxon name, etc.) is treated equally, so that you can take a publication and see what taxa it refers to, or take the taxon and find all the publications that refer to the taxon. Although the database has been seeded with some articles from Molecular Phylogenetics and Evolution, much of the data comes from GenBank, PubMed, and specimen databases. These are accessed through http://bioguid.info, a tool I constructed to resolve globally unique identifiers and return associated metadata.
