Using Multiple Views for Visual Exploration of Ontologies
نویسندگان
چکیده
In this paper, we present a multiple views approach for exploring relationships between ontology classes and their instances. We employ thumbnails, 2D and 2.5D hyperbolic trees, which capture the hierarchical feature of parts of the ontology, while preserving the different categories of relationships between classes. In 2.5D visualization, the ontology is displayed as a tree on a plane, representing only the hierarchical relationships between concepts, and the user can explore other connections by creating projections of nodes (concepts) in another plane and linking them according to the relationships to be analysed. We report the comparison of our tool to Ontograf and propose a visualization method for the representation of instances of ontology classes.

متن کاملInteractive Visual Exploration and Analysis
Interactive exploration and analysis of multi-field data utilizes a tight feedback loop of computation/visualization and user interaction to facilitate knowledge discovery in complex datasets. It does so by providing both overview visualizations, as well as support for focusing on features utilizing iterative drill-down operations. When exploring multi-field data, interactive exploration and an...
متن کاملMultidimensional Data Exploration by Explicitly Controlled Animation
Understanding large multidimensional datasets is one of the most challenging problems in visual data exploration. One key challenge that increases the size of the exploration space is the number of views that one can generate from a single dataset, based on the use of multiple parameter values and exploration paths. Often, no such single view contains all needed insights. The question thus aris...
متن کاملExPlates: Spatializing Interactive Analysis to Scaffold Visual Exploration
Visual exploration involves using visual representations to investigate data where the goals of the process are unclear and poorly defined. However, this often places unduly high cognitive load on the user, particularly in terms of keeping track of multiple investigative branches, remembering earlier results, and correlating between different views. We propose a new methodology for automaticall...

Background and Aim: Ontologies facilitate data integration, exchange, searching and querying. Open Biomedical Ontologies (OBO) Foundry is a solution for creating reference ontologies. In this foundry, the design of ontologies is based on established principles which allow for their interactions as a single system. The purpose of this study is to determine the main features of ontologies develop...
