Interesting. Could one graph be the topological representation, let's say like SCC? So there are heterogenous graphs with meta-graphs connected to them...?
There are a lot of cool experiments happening like this, both principled and from intuition
Ex:Label prop following non-local jumps ("metapaths") based on community detection (network-of-network, ...) or other shapes. Same thing for what constitutes a feature.
Michael Bronstein's papers (and talks!) are often in this vein, in the mainstream, leading, and quite accessible, so would recommend starting there..
