enrich_event()

void SM_nf_emotions::default_media_user::enrich_event ( media_event *  _event )

overridevirtual

Enirches the event with information.

By default this is called after every event is created by this class. The last operation in this function is Social_Media_no_followers::finalize_event. Any functions that override this function should call this function after performing all other operations.

Reimplemented from Social_Media_no_followers::default_media_user.

Reimplemented in SM_wf_emotions::default_media_user.

Here is the call graph for this function:

generate_post_events()

void SM_nf_emotions::default_media_user::generate_post_events ( void  )

overridevirtual

Modifies Social_Media_no_followers::default_media_user::generate_post_events to use emotions.

The equation for calcuating the probability density for posting is updated to \(P^{(post)}_i=pdp_i+\sum_mB_{i,m}E_{i,m}+\sum_{n,m}C_{n,m}E_{i,n}E_{i,m}\) where \(pdp_i\) is Social_Media_no_followers::default_media_user::pdp, \(B\) is the "first order post density emotion network", \(C\) is the "second order post density emotion network", and \(E\) is the "emotion network". Additionally, emotions are attached to an event using add_emotions.

Here is the caller graph for this function:

get_knowledge_selection()

unsigned int SM_nf_emotions::default_media_user::get_knowledge_selection ( void  )

virtual

Modifies Social_Media_no_followers::default_media_user::get_knowledge_selection to use emotions.

Each piece of knowledge is assigned a probability weight based on the following equation, \(P_{i,k}=(A_{i,k}+\sum_mB_{i,k}|T_{i,k}-0.5|+\sum_mC_{k,m}E_{i,m})*K_{i,k}\), where \(A\) is the "knowledge select bias network", \(B\) is the "knowledge select trust network", \(T\) is the "knowledge trust network", \(C\) is the "knowledge select emotion network", \(E\) is the "emotion network", and \(K\) is the "knowledge network". After calculating all the weights Random::find_dist_index is used to select the knowledge index for creating an event. If all probability weights are zero, a dynet::construct_exception is thrown.
