I'm wondering if you would like to add the Spreading Activation algorithm to GraphX. I have implemented it, using the Pregel-API and would love to share it with the community.

Spreading activation is a algorithm that was invented to search in associative networks. The basic idea is, that you have one (or multiple) starting nodes. The activation spreads out from these nodes to the neighbours and the neighbours of the neighbours. The activation decreases after every hop. Nodes that were reached by many activations will have a higher total activation level.

Spreading Activation is for many use cases useful. Imagine you have the social network of two people. If you apply the spreading activation to this social graph with the two people as starting nodes, you will get the nodes that are most important for both.
