Stardog similarity search query through jena

Support

The Jena parser doesn't know about the custom aggregate functions.

That being said, there is the possibility to register custom aggregate functions via ARQ, e.g.

/* Registration */
AggregateRegistry.register(aggUri, myAccumulatorFactory, NodeConst.nodeMinusOne);

shown in this example code

I don't know whether this already exists for Stardog somewhere. The devs should know it better indeed.
