Abstract: A system that determines whether a non-uniquely identified name substantially corresponds to a uniquely identified person. A source dataset of uniquely identified persons is accessed, where the source dataset has records including, for each uniquely identified person, a source name, a source unique identifier, a source date of birth, and a source address. A target dataset of non-uniquely identified persons is also accessed, where the target dataset has records that include, for each non-uniquely identified person, a target name, and either (1) a target age and a target age-date indicating an exact or approximate date of the target age, or (2) a target address. For a particular source person in the source dataset, whether the particular source person corresponds to a particular target person in the target dataset is determined automatically in accordance with the accessing.
