---------------------------------
Resolution: Incomplete
> add Spreading Activation algorithm to GraphX
> --------------------------------------------
>
> Key: SPARK-7966
> URL: https://issues.apache.org/jira/browse/SPARK-7966
> Project: Spark
> Issue Type: Improvement
> Components: GraphX
> Reporter: Tarek Auel
> Priority: Minor
> Labels: bulk-closed
>
> 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.
