Advanced Uses of FIRST
How FIRST materializes its learning – PAG’s

Our thesis is that PAG’s, Potential Affinity Groups, could be suggested based on Top nk-ads of order higher than three. It means for instance, that Top triads suggest that users using those triads have a high probability of having interests in common. The vertical blue column, shown at right in the nk-Thesaurus, accounts for the popularity of nk-ads. The blue column at left, in the Users’ Tracks Login Database, corresponds to the ID’s Tags of sessions.

So we may correlate TOP nk-ads to users ID’s and those correspondences lead us to suggest PAG’s.
