Generation of training data from redacted information

An apparatus, comprising:

• at least one processor;
• and
• a computer readable storage medium having computer readable program code embodied therewith and executable by the at least one processor:
• wherein the computer readable program code is configured to obtain an information document corresponding to an entity, wherein the information document comprises redacted information spans;
• wherein the computer readable program code is configured to identify an entity type for each of the redacted information spans, wherein the entity type identifies a relationship between a redacted information span and at least one other entity within the information document;
• wherein the computer readable program code is configured to replace the redacted information spans with replacement entities corresponding to the entity type of a given redacted information span, wherein the replacing is performed in view of a frequency distribution of actual information and wherein the replacing comprises maintaining relationships of the redacted information spans;
• and
• wherein the computer readable program code is configured to control bias within the replacement entities, wherein the controlling comprises detecting bias within the replacement entities.
