Latest GraphDB Edition Available

April 25, 2019

A new version of GraphDB is now available, we learn from the company’s News post, “Ontotext’s GraphDB 8.9 Boosts Semantic Similarity Search.” The semantic graph database offers a couple new features inspired by user feedback. We learn:

“The semantic similarity search is based on the Random Indexing algorithm. … The latest GraphDB release enables users to create hybrid similarity searches using pre-built text-based similarity vectors for the predication-based similarity index. The index combines the power of graph topology with the text similarity. The users can control the index accuracy by specifying the number of iterations required to refine the embeddings. Another improvement is that now GraphDB 8.9 allows users to boost the term weights when searching in text-based similarity indexes. It also simplifies the processes of abortion of running queries or updates from the SPARQL editor in the Workbench.”

The database continues to be updated to the current RDF4J 2.4.6 public release. GraphDB comes in Free, Standard, and Enterprise editions. Begun in 2000, Ontotext is based in Sofia, Bulgaria, and maintains its North American office in New York City.
