Techniques for document marker tracking

A non-transitory computer-readable storage medium storing a plurality of instructions executable by one or more processors, the plurality of instructions when executed by the one or more processors cause the one or more processors to:

• receive information identifying a first document and a second document, the first document including a first marker located at a first location in the first document, wherein the second document is a modified version of the first document;
• identify a first token list comprising a plurality of tokens corresponding to words within the first document;
• identify a second token list comprising a plurality of tokens corresponding to words within the second document which is the modified version of the first document;
• generate a first set of one or more token groups for the first document based upon the first token list;
• generate a second set of one or more token groups for the second document based upon the second token list;
• identify differences between the first token list and the second token list;
• generate, based upon the differences between the first token list and the second token list, a group mapping between the first set of one or more token groups and the second set of one or more token groups;
• identify, based upon the first location of the first marker in the first document, a first token from the first token list;
• identify, from the first set of one or more token groups generated for the first document, a first token group that includes the first token;
• identify, for the first token group and based on the group mapping, a second token group from the second set of one or more token groups;
• determine a location of the second token group within the second document;
• and
• add a second marker to the second document at a location in the second document based upon the location of the second token group within the second document.

A system comprising:

• one or more processors;
• and
• a non-transitory computer-readable medium including instructions that, when executed by the one or more processors, cause the one or more processors to:
• receive information identifying a first document and a second document, the first document including a first marker located at a first location in the first document, wherein the second document is a modified version of the first document;
• identify a first token list comprising a plurality of tokens corresponding to words within the first document;
• identify a second token list comprising a plurality of tokens corresponding to words within the second document which is the modified version of the first document;
• generate a first set of one or more token groups for the first document based upon the first token list;
• generate a second set of one or more token groups for the second document based upon the second token list;
• identify differences between the first token list and the second token list;
• generate, based upon the differences between the first token list and the second token list, a group mapping between the first set of one or more token groups and the second set of one or more token groups;
• identify, based upon the first location of the first marker in the first document, a first token from the first token list;
• identify, from the first set of one or more token groups generated for the first document, a first token group that includes the first token;
• identify, for the first token group and based on the group mapping, a second token group from the second set of one or more token groups;
• determine a location of the second token group within the second document;
• and
• add a second marker to the second document at a location in the second document based upon the location of the second token group within the second document.
