问题 I have a problem with a rule match in Clips, in particular i can't understand why this rule doesn't actives.

问题 This is a follow-up question from SPARQL 1.1 entailment regimes and query with FROM clause I'm currently documenting/testing about SPARQL 1.1 entailment regimes and the recommendation repeatedly states that The scoping graph is graph-equivalent to the active graph...

I created a semantic Graph in Neo4j. Is there any possibility to use an OWL reasoner in Neo4j? Or any inference engine? Though it has been mentioned here i can't find any solution or API for this. Thankful for any advice! Maybe you want to see this: click here I quoted this from that link: Your main task if you want to use reasoners over a neo4j database is going to be to suck data out of neo4j, and format it as a set of RDF triples. You can then put those RDF triples into a Jena Model. When you have that jena model in memory, you can use existing jena APIs to use reasoners with that model My
