According to a recent press release, “Ontotext has released the 9.2 version of GraphDB – the most powerful RDF database for creating and maintaining knowledge graphs. In addition to the anticipated support for RDF*/SPARQL*, it brings improvements in the plug-ins for semantic similarity and versioning. The new Proof plug-in provides inference explanation… Knowledge graphs are the next generation tool for helping businesses make critical decisions based on harmonized knowledge models derived from siloed source systems. For this reason, more and more organizations are turning to knowledge graphs for better enterprise knowledge management, data and content analytics.”
The release continues, “GraphDB 9.2 upgrades the modeling expressivity of the database with RDF*/SPARQL* – the most widely supported extension of those standards, which will be part of RDF 1.2. In RDF* one can make statements about statements, formally called statement-level annotations. For example, one can provide time span for an employment relationship like this: (Joe works-for BigBucks) from 1/1/2018 to 30/3/2020. This mechanism goes beyond the expressivity of the Property Graphs, where one can attach key-value pairs to relationships. The statement-level annotations enable a more efficient representation of scores, weights, temporal restrictions and provenance information.”
