SYSTEMS AND METHODS FOR ANNOTATING DATASETS

Disclosed herein are systems and methods for joining datasets. The system may include one or more processors and a memory storing instructions that, when executed by the one or more processors. The processor may cause the system to perform determining at least a first database table to be annotated, the first database table including a set of columns and rows of a dataset. In some embodiments, the system may include determining at least one typeclass that applies to one or more columns included in the first database table, wherein the typeclass describes values stored in the one or more columns and annotating the one or more columns, wherein the annotated columns are associated with the typeclass.
