1. A system for using location transformations to identify objects, the system comprising: one or more processors; and a non-transitory computer readable medium storing a plurality of instructions, which when executed, cause the one or more processors to: generate a plurality of word pairs, wherein each word pair comprises a first word from a first document and a corresponding second word from a second document; compute, for each word pair, first location information for the first word that indicates a location of the first word in the first document relative to other words in the first document; compute, for each word pair, second location information for the corresponding second word that indicates a location of the corresponding second word in the second document relative to other words in the second document; identify a transformation based on a comparison between the first location information and the second location information, wherein the transformation comprises at least one of a translation, a rotation, and a scale; apply the transformation to the second location information; determine whether a difference between the first location information and transformed second location information is less than a threshold value; identify a first anchor in the first document in response to a determination that the difference between the first location information and the transformed second location information is less than the threshold value; and identify a second anchor in the second document based on the first anchor and the transformation.

The system of claim 1 , wherein the processor-based system is further configured to identify a field in the second document based on the second anchor and at least partially based on the transformation.
