FIELD: computer technology.

SUBSTANCE: invention relates to the field of computer technology and can be used to detect fields on document images. The method involves obtaining a training dataset containing several documents, and each of several documents correlates with several fields marked up by the user; for a given field from several user-marked fields in this document from several documents, determining whether a specific combination of relative positions of one or more additional user-marked fields relative to this field is repeated in one or more additional documents in this document; indicating that the selection of this field is incorrect if it is established that a specific combination is not repeated in any additional documents; establishing the presence in two or more other documents of another combination of relative positions of additional one or more fields marked up by the user, relative to this field, if it is established that a specific combination is repeated in one or more additional documents, and specifying this field as marked up correctly if it is established that another combination does not exist in two or more other documents; specifying this field as marked up is contradictory if it is established that this combination exists in two or more other documents.

EFFECT: determining the accuracy of user markup of fields in documents.
