19. The computer-implemented system of claim 13 , wherein the one or more rules resulting from one or more previously performed machine learning operations are selected for inclusion within the set of seed rules based on a commonality between the one or more previously performed machine learning operations and the one or more newly performed machine learning operations.
13. 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: perform one or more machine learning operations on a set of seed rules to generate a new set of rules for determining whether a given pair of information items have a specific relationship, wherein the set of seed rules comprises one or more rules resulting from one or more previously performed machine learning operations and one or more randomly or pseudo-randomly generated rules, wherein: the one or more previously performed machine learning operations were performed in regard to a set of information items including one or more differences from another set of information items used in generating the new set of rules, or the specific relationship is different than another specific relationship for which the new set of rules was generated; and apply the new set of rules to one or more pairs of information items to identify at least one pair of information items as having the specific relationship.
