Abstract:We explore how to support the creation of customized visualizations of ontology instance data through the specification of ontology mappings. We combine technologies from the disciplines of software modeling and ontology engineering. The feasibility of our approach is demonstrated by extending an existing ontology mapping tool, COGZ, to translate ontology mappings into software model transformation rules. The tool uses these transformations to automatically convert domain instance data into data that conforms … Show more
“…Visualizations for ontologies -hierarchical knowledge taxonomies for particular text domains -have been explored extensively in previous work. Visual encodings have included the use of indented lists, space-filling techniques [14,27], and node-link graphs [17,27] [10], and used to validate a single topic model is similar to what is captured by an ontology mapping. Unlike hierarchical ontologies, which often have high-level concepts that map to several topics, they expect an optimal one-to-one alignment.…”

“…In the last decade, new research proposes the use of an ontology to specify how its content should be visualized, as well as for defining the user interaction [14][15][16]. One of the most generic and reusable results is the ontology Visualization Ontology (VISO) [16].…”

“…These tools are used to see the ontology and navigate through it to see its instances [13]. Recent projects use ontologies in order to know how to show the content of an ontology [14,15]. One of the most advanced is the one proposed by the VISO ontology [16].…”
Interactive visualization of spatio-temporal data is a very active area that has experienced remarkable advances in the last decade. This is due to the emergence of fields of research such as big data and advances in hardware that allow better analysis of information. This article describes the methodology followed and the design of an open source tool, which in addition to interactively visualizing spatio-temporal data that are represented in an ontology, allows the definition of what to visualize and how to do it. The tool allows selecting, filtering and visualizing in a graphical way the entities of the ontology with spatiotemporal data, as well as the instances related to them. The graphical elements used to display the information are specified on the same ontology, extending the VISO graphic ontology, used for mapping concepts to graphic objects with RDFS/OWL Visualization Language (RVL). This extension contemplates the data visualization on rich real-time 3D environments, allowing different modes of visualization according to the level of detail of the scene, while also emphasizing the treatment of spatio-temporal data, very often used in cultural heritage models. This visualization tool involves simple visualization scenarios and high interaction environments that allow complex comparative analysis. It combines traditional solutions, like hypercube or time-animations with innovative data selection methods.

The Information Technology system use visualization to represent data in different forms. Some new researches in this field working on extract Knowledge, rapid information retrieval from the graphical diagram. Therefore, data visualization now trends to use ontology approach to build a robust knowledge-based system. The proposed of this paper is to developed ontology approach and use software tools to improve visualized knowledge. Moreover, study data visualization subject in term of ontology and how to facilitate understanding it on the end user. Computer networks ontology adopted as a case study to prove the important of this approach. The Object Role Modeling (ORM) is a visualized notation used to build the prototype for ontology, and OntoGraf module in the Proté gé tool used to build ontology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
