Systems and methods for matching and scoring sameness

Systems and methods for matching and scoring sameness. In some embodiments, a computer implemented method is provided, comprising acts of: identifying a plurality of first-degree anchor values from the first digital interaction, wherein the plurality of first-degree anchor values comprise first-degree anchor values X and Y; accessing a profile of the first-degree anchor value X, wherein: the profile of the first-degree anchor value X comprises a plurality of sets of second-degree anchor values; and each set of the plurality of sets of second-degree anchor values corresponds to a respective anchor type and comprises one or more second-degree anchor values of that anchor type; determining how closely the first-degree anchor values X and Y are associated; and generating an association score indicative of how closely the plurality of first-degree anchors are associated, based at least in part on how closely the first-degree anchor values X and Y are associated.
