Propagation of changes in master content to variant content

A computer-implemented system comprising:

• at least one processor;
• and
• computer storage media storing computer-useable instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
• receiving, from a user interface, a modified master text composition that incorporates a modification to a master text composition;
• dividing the master text composition into text units, dividing the modified master text composition into text units, and dividing a variant text composition assigned to the master text composition into text units;
• constructing a correspondence model comprising a first mapping between a first text unit of the text units of the master text composition and a second text unit of the text units of the modified master text composition, and a second mapping between a third text unit of the text units of the variant text composition and the first text unit of the text units of the master text composition;
• determining a proposed modification to the third text unit of the variant text composition that corresponds to the modification to the master text composition based on the first mapping and the second mapping;
• integrating the proposed modification into the variant text composition.

At least one computer storage device storing computer-useable instructions that, when used by the at least one computing device, cause the at least one computing device to perform a method comprising:

• receiving, from a user, a modified master text composition in association with a master content fragment, the modified master text composition incorporating a modification to a master text composition in the master content fragment;
• dividing the master text composition into text units, dividing the modified master text composition into text units, and dividing a variant text composition of a variant content fragment assigned to the master content fragment into text units;
• constructing a correspondence model comprising a first similarity score between a first text unit of the text units of the master text composition and a second text unit of the text units of the modified master text composition, and a second similarity score between a third text unit of the text units of the variant text composition and the first text unit of the text units of the master text composition;
• extracting a first mapping between the first text unit of the master text composition and the second text unit of the modified master text composition from the correspondence model based on the first similarity score, and extracting a second mapping between the third text unit of the variant text composition and the first text unit of the master text composition from the correspondence model based on the second similarity score;
• determining a proposed modification to the third text unit of the variant text composition that correspond to the modification to the master text composition based on the first mapping and the second mapping;
• displaying text of the third text unit of the variant text composition with a visual indication of the proposed modification in a user interface on a user device associated with the user;
• and
• storing a modified variant text composition that incorporates the proposed modification to the variant content fragment in response to a user selection in the user interface of an option to accept the proposed modification.
