15. A system, comprising: a memory; and one or more processors coupled to the memory, wherein the memory comprises program instructions executable by the one or more processors to: based on reference data that includes pairs of information items and labels that each indicate whether a given pair of information items have a specific relationship, generate a first machine learning model for determining whether pairs of information items have said specific relationship; identify one or more false positive pairs, wherein a given false positive pair is a pair of information items that the first machine learning model indicates as having said specific relationship and which are labeled within the reference data as not having said specific relationship; generate an indication of one or more of the identified false positive pairs as candidates to be corrected within the reference data.

The system of claim 15 , wherein the first machine learning model is a support vector machine (SVM) model including slack variables associated with different pairs of information items mapped in a hyperspace, wherein the program instructions are configured to, based on the slack variables, select one or more false positive pairs as candidates to be corrected.
