Abstract: Some embodiments may be directed to matching users, such as employees, with insurance records in an integrated database, wherein the integrated database includes a plurality of insurance records, each record being associated with a unique employee and having a plurality of fields. According to some embodiments, new employee information may be received and it may be determined that the new employee information does not qualify as a strong match with any insurance record in the integrated database. Moreover, it may be determined, based on a probabilistic pattern match of the new employee information with values in the fields of the integrated database, that the new employee information qualifies as a weak match with a particular insurance record in the integrated database.
