Datasets
Clavius is a a Web platform using current technologies of computational linguistics, knowledge engineering, digital philology, Web of Data and information visualization. It has a Linked Open Data set containing letters, places and persons related to the works and the correspondence of the astronomer Christophorus Clavius.
DoGi represents one of the main online consulted source of information for articles published on italian juridical journals. It contains bibliographic information, abstracts, summaries and other manually selected data about more than 400 paper prints and electronic journal articles.
Applications
The atlas of DBpedia: a map-like representation of DBpedia developed using the Linked Data maps approach.
The atlas of LinkedMDB: a map-like representation of LinkedMDB developed using the Linked Data maps approach.
Lod Cloud: an interative visualization of the Linked Open Data (LOD) Cloud represented as a universe of planet. Search feature, developed using the CKAN.net API, allows to find a dataset in the LOD cloud.
SpaceTime: a tool for exploring DBpedia using the space and time dimension through a map and a timeline.
Meteo: a D3.js visualization using the open data of Lamma published on OpenToscana.
Research
State of the Art: a collection of scientific articles, applications and tools about the visualization, exploration and navigation of Linked Data sets.
