Selected Feedback from Users
“Year after year, Ontotext continuously improves its graph database GraphDB with the latest features produced by the W3C (RDF*, Property paths, SHACL) thanks to its integration of RDF4j. Perfect Memory has chosen GraphDB because of the quality of the product and its team, and the extensive use of semantic inference our platform Raffiné™ makes, which is very often the pain point of all the triplestores we have benchmarked. Our partnership allows us to build a quality customized Enterprise Knowledge Graph for each of our clients.”
CTO, Perfect Memory
