At Netage B.V we have been enthusiastic users of Stardog since version 4. We have created various standard RDF Graph solutions on top of the Stardog Knowledge Graph product which helps us gain a lot of experience with this product.
We have also used most of the more advanced technologies available in Stardog and will share some of our experience through our blog.
The first blog is by Nicky van Oorschot and talks about the machine learning component to find similarities in the graph. If you are interested in learning more or deploying these technologies in your organization let us know!
