Description

rdf:SynopsViz is a tool for hierarchical charting and visual exploration of RDF & Linked Open Data. Hierarchical RDF exploration is based on the creation of multiple levels of hierarchically related groups of resources based on the values of one or more properties. 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 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. The latter are useful for assessing data quality.
