Method Detail

getMinerWeight

public double getMinerWeight(java.lang.String minerName)

Retrieves the weight associated with the provided miner name.

Parameters:

minerName - The registered miner's name.

Returns:

A double in the range [0, 1], 1 if the weight has never been set.

See Also:

setMinerWeight(String, double)

setMinerWeight

public SocialGraphMinerCombination setMinerWeight(java.lang.String minerName,
                                                  double minerWeight)

Gets a created miner with SocialGraphMinerCombination.getMiner(String) and associates a new weight with it. Miner weight of zero makes the miner not participate in predictions. predictNewInteraction(Context, Node) and SocialGraphMiner.recommendInteractions(Context).

Parameters:

minerName - The name of the miner whose weight is set.

minerWeight - The weight to associate with the miner. Should lie in the range [0,1].

Returns:

this miner.

getMinerWeight(String), SocialGraphMinerCombination.createMiner(String, Class)

predictNewInteraction

public double predictNewInteraction(eu.h2020.helios_social.core.contextualegonetwork.Context context,
                                    eu.h2020.helios_social.core.contextualegonetwork.Node destinationNode)

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).
