Description copied from class: SocialGraphMiner

Predicts the weight of performing a SEND interaction between the given context's ego and a destination node within a given context. This method should typically return values in the [0,1] range, where higher values correspond to more likely interactions.

Specified by:

predictNewInteraction in class SocialGraphMiner

Parameters:

context - The context in which to perform the prediction.

destinationNode - The destination node of the interaction.

Returns:

The weight of performing the interaction (higher values are more likely).
