Abstract: Disclosed embodiments may include systems and methods for entity resolution. The system may receive a first plurality of identifiers and a taxpayer identification number. The system may determine one or more profiles preliminarily associated with the entity the one or more profiles including a plurality of data entries. The system may convert the plurality of data entries from a non-standardized format to a standardized format. The system may compare the first plurality of identifiers and the taxpayer identification number to the plurality of data entries to determine an entity match. In some examples, the system can vectorize the first plurality of identifiers and the taxpayer identification number into a first vectorized dataset and the plurality of data entries into one or more second vectorized datasets. The system may compare the first vectorized dataset to the one or more second vectorized dataset to determine an entity match.
