eu.h2020.helios_social.modules.socialgraphmining.combination.SwitchableMiner

public class SwitchableMiner
extends SocialGraphMinerCombination

This class enables switching between different SocialGraphMiner implementations. It extends the miner management of SocialGraphMinerCombination. The active miner can be selected using the setActiveMiner(String) method.

Constructor Detail

SwitchableMiner

public SwitchableMiner(eu.h2020.helios_social.core.contextualegonetwork.ContextualEgoNetwork contextualEgoNetwork)

Method Detail

getActiveMiner

public SocialGraphMiner getActiveMiner()

Retrieves the active miner.

Returns:

The active miner.

See Also:

setActiveMiner(String)

setActiveMiner

public SocialGraphMiner setActiveMiner(java.lang.String minerName)

Gets a created miner with SocialGraphMinerCombination.getMiner(String) and, if such a miner is found, this is set as the active miner. The active miner is subsequently called to expose its outcome of predictNewInteraction(Context, Node) and recommendInteractions(Context). Other functionalities are shared between all created miners.

Parameters:

minerName - The name of the miner to set as the active one.

Returns:

The new active miner.

getActiveMiner(), 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).

recommendInteractions

public java.util.HashMap<eu.h2020.helios_social.core.contextualegonetwork.Node,java.lang.Double> recommendInteractions(eu.h2020.helios_social.core.contextualegonetwork.Context context)

Description copied from class: SocialGraphMiner

Calls SocialGraphMiner.predictNewInteraction(Context, Node) to score the likelihood of interacting with all nodes of the given context.

Overrides:

recommendInteractions in class SocialGraphMiner

Parameters:

context - The context for which to recommend interactions.

Returns:

A hash map of node scores (larger is more likely to occur.
