9. The system of claim 5 , wherein the plurality of decision trees is a decision tree in a random forest of decision trees.
5. A system, comprising: one or more processors; and memory including instructions that, when executed by the one or more processors, cause the system to: determine a set of frequencies for a set of details associated with a request to determine an identity of a user; obtain a set of records based at least in part on the set of details; determine a set of scores for at least a subset of the set of records, the set of scores determined by at least, for each record of the set of records: computing a set of search term results for the set of details, the set of search term results indicating an extent to which the set of details corresponds to the subset of the set of records; calculating, based at least in part on the set of frequencies and a set of search term results, a subset of the set of records to analyze; analyzing the subset of the set of records by at least traversing, for each frequency of the set of frequencies corresponding to the subset of the set of records, a plurality of decision trees to generate a plurality of votes; and generating the set of scores based at least in part on the plurality of votes; and determine the identity based at least in part on the set of scores.
