Class RecommendedSightMechanism<U extends java.io.Serializable,​I extends java.io.Serializable,​P>

java.lang.Object
es.uam.eps.ir.relison.diffusion.sight.IndividualSightMechanism<U,​I,​P>
es.uam.eps.ir.relison.diffusion.sight.RecommendedSightMechanism<U,​I,​P>
Type Parameters:
U - type of the users.
I - type of the information pieces.
P - type of the parameters.
All Implemented Interfaces:
SightMechanism<U,​I,​P>
public class RecommendedSightMechanism<U extends java.io.Serializable,​I extends java.io.Serializable,​P>
extends IndividualSightMechanism<U,​I,​P>
This mechanism applies two different probabilities: one for observing information pieces from recommended users, and other for observing information pieces from training users.

  • Method Summary

    Modifier and Type Method Description
    void resetSelections​(Data<U,​I,​P> data)
    For each user, this method preconfigures the sight mechanism (for example, selecting a fixed set of users whom each user pays attention to).
    boolean seesInformation​(UserState<U> user, Data<U,​I,​P> data, PropagatedInformation prop)
    Checks if a user sees or not a piece of information.
