PROMPT-Viz: Ontology Version Comparison Visualizations with Treemaps
نویسندگان
چکیده
Current trends indicate that the prevalence of ontologies will continue to increase within many domains. They are already commonly used to define controlled medical terminologies and form the backbone of the Semantic Web initiative. Very few tools that support versioning of ontologies are currently available, and those that provide difference detection and visualization are particularly lacking. We have implemented a tool called PROMPT-Viz that provides advanced visualizations using treemaps to help understand the location, impact, type and extent of changes that have occurred between versions on an ontology. PROMPT-Viz runs as a plug-in for the popular Protégé knowledge engineering environment and as such should be applicable to a large number of ontology developers.

Top-down Data Analysis with Treemaps
Statistics Netherlands produces statistics about the economic activity in The Netherlands. These statistics are based on survey data and administrative sources, such as value added tax (VAT). A recent trend in the production of official statistics is to use a top-down analysis, which means that analysts first analyze high level aggregated data, and then zoom in on a more detailed level when nec...
متن کاملDAGmaps: Space Filling Visualization of Directed Acyclic Graphs
Gene Ontology information related to the biological role of genes is organized in a hierarchical manner that can be represented by a directed acyclic graph (DAG). Space filling visualizations, such as the treemaps, have the capacity to display thousands of items legibly in limited space via a two-dimensional rectangular map. Treemaps have been used to visualize the Gene Ontology by first transf...
متن کاملMulti-View Ontology Explorer (MOE): Interactive Visual Exploration of Ontologies
An ontology is an explicit specification of a conceptualization. This specification consists of a common vocabulary and information structure of a domain. Ontologies have applications in many fields to semantically link information in a standardized manner. In these fields, it is often crucial for both expert and non-expert users to quickly grasp the contents of an ontology; and to achieve this...
متن کاملData Exploration with Paired Hierarchical Visualizations: Initial Designs of Pair Trees
Paired hierarchical visualizations (PairTrees) integrate treemaps, node-link diagrams, choropleth maps and other information visualization techniques to support exploration of hierarchical data sets at multiple levels of abstraction (Kules, Shneiderman et al., in press). Coordinated visualizations are an effective way to support exploratory data analysis of multidimensional data sets. Hierarchi...
متن کاملREVIGO Summarizes and Visualizes Long Lists of Gene Ontology Terms
Outcomes of high-throughput biological experiments are typically interpreted by statistical testing for enriched gene functional categories defined by the Gene Ontology (GO). The resulting lists of GO terms may be large and highly redundant, and thus difficult to interpret.REVIGO is a Web server that summarizes long, unintelligible lists of GO terms by finding a representative subset of the ter...
