Description

rdf:SynopsViz is a tool for scalable multi-level charting and visual exploration of very large RDF & Linked Data datasets. The adopted hierarchical model provides effective information abstraction and summarization. Also, it allows efficient -on the fly- statistic computations, using aggregations over the hierarchy levels.


Key Features

  • It adopts a hierarchical multi-level model for RDF data visualization, browsing and analysis.
  • It offers automatic on-the-fly hierarchy construction based on data distribution, as well as user-defined hierarchy construction based on user's preferences.
  • Provides faceted browsing and filtering over classes and properties.
  • Integrates statistics with visualization; visualizations have been enriched with useful statistics and data information.
  • Offers several visualizations techniques (e.g., timeline, chart, treemap).
  • Provides a large number of dataset's statistics regarding the: data-level (e.g., number of sameAs triples), schema-level (e.g., most common classes/properties), and structure level (e.g., entities with the larger in-degree).
  • Provides numerous metadata related to the dataset: licensing, provenance, linking, availability, undesirability, etc.
