SPARQLcity Graph Analytics Engine
SPARQLverse is the graph analytics engine produced by SPARQLcity. Standards compliant and super fast!

I’ve been spending a lot of time this past year running queries against the open source SPARQLverse graph analytic engine.  It’s amazing how simple some queries can look and yet how much work is being done behind the scenes.

My current project requires building up a set of query examples that allow typical kinds of graph/network analytics – starting with the kinds of queries needed for Social Network Analysis (SNA), i.e. find friends of friends, graph density and more.

In this post I go through computing graph density in detail. Continue reading “SPARQL Query for Graph Density Analysis”
