Abstract

Systems and methods are disclosed for comparing annotations in files to show changes in the annotations at a granular level. In one implementation, a system receives a first file and a second file for comparison. The system determines the annotation ranges for each annotation in the first file and the annotation range for each annotation in the second file. The system then determines the annotations from the first file that overlap with annotations from the second file and compares annotations that overlap. The system then incorporates the comparison of the annotations into a main comparison file. In certain implementations, the system uses an index to determine what annotations overlap. In other implementations, matched pairs are created from overlapping annotations.

Claims

1-38. -38. (canceled)

39. A computer-based system for indicating differences in annotations within files comprising:

a memory storing instructions; and

a processor configured to execute the instructions to;

identify a first annotation in a first electronic file;

determine whether a second electronic file contains a matching annotation corresponding to the first annotation; and

generate information for displaying a comparison output including an indication that the second electronic file does not contain a matching annotation.

40. The computer-based system of claim 39, wherein the processor is further configured to:

identify first annotation content corresponding to the first annotation;

identify second annotation content corresponding to a second annotation in the second electronic file;

create an index including the first annotation content and the second annotation content;

determine, based on the index, whether the second annotation is a matching annotation corresponding to the first annotation.

41. The computer-based system of claim 39, wherein the processor is further configured to:

identify a first annotation location corresponding to the first annotation;

identify a second annotation location corresponding to a second annotation in the second electronic file;

create an index including the first annotation location and the second annotation location;

determine, based on the index, whether the second annotation is a matching annotation corresponding to the first annotation.

42. The computer-based system of claim 40, wherein the processor is further configured to:

identify a first annotation location corresponding to the first annotation;

identify a second annotation location corresponding to a second annotation in the second electronic file;

incorporate, in the index, the first annotation location and the second annotation location;

determine, based on the index, whether the second annotation is a matching annotation corresponding to the first annotation.

43. The computer-based system of claim 39, wherein the processor is located remotely from a memory storing one of the first electronic file or the second electronic file.

44. The computer-based system of claim 39, wherein the comparison output includes an indication that the first annotation was deleted when the second electronic file does not contain a matching annotation.

45. The computer-based system of claim 39, wherein the comparison output includes an indication that the first annotation was inserted, when the second electronic file does not contain a matching annotation.

46. The computer-based system of claim 39, wherein the comparison output is at least one of a document, spreadsheet, text file, image, or database file.

47. The computer-based system of claim 39, wherein the processor is further configured to:

receive the first electronic file for comparison,

receive the second electronic file for comparison,

compare the first electronic file with the second electronic file, and

generate information for displaying, within the comparison output, differences between the first electronic file and the second electronic file.

48. A computer-implemented method for indicating differences in annotations within files, the method comprising:

identifying, by a processor, a first annotation in a first electronic file;

determining, by the processor, whether a second electronic file contains a matching annotation corresponding to the first annotation; and

generating, by the processor, information for displaying a comparison output including an indication that the second electronic file does not contain a matching annotation.

49. The computer-implemented method of claim 48, further comprising:

identifying, by the processor, first annotation content corresponding to the first annotation;

identifying, by the processor, second annotation content corresponding to a second annotation in the second electronic file;

creating, by the processor, an index including the first annotation content and the second annotation content;

determining based on the index, by the processor, whether the second annotation is a matching annotation corresponding to the first annotation.

50. The computer-implemented method of claim 48, further comprising:

identifying, by the processor, a first annotation location corresponding to the first annotation;

identifying, by the processor, a second annotation location corresponding to a second annotation in the second electronic file;

creating, by the processor, an index including the first annotation location and the second annotation location;

determining based on the index, by the processor, whether the second annotation is a matching annotation corresponding to the first annotation.

51. The computer-implemented method of claim 49, further comprising:

identifying, by the processor, a first annotation location corresponding to the first annotation;

identifying, by the processor, a second annotation location corresponding to a second annotation in the second electronic file;

incorporating, by the processor, the first annotation location and the second annotation location in the index;

determining based on the index, by the processor, whether the second annotation is a matching annotation corresponding to the first annotation.

52. The computer-implemented method of claim 48, wherein the method is performed by a processor located remotely from a memory storing one of the first electronic file or the second electronic file.

53. The computer-implemented method of claim 48, wherein the comparison output includes an indication that the first annotation was deleted when the second electronic file does not contain a matching annotation.

54. The computer-implemented method of claim 48, wherein the comparison output includes an indication that the first annotation was inserted, when the second electronic file does not contain a matching annotation.

55. The computer-implemented method of claim 48, wherein the comparison output is at least one of a document, spreadsheet, text file, image, or database file.

56. The computer-implemented method of claim 48, further comprising:

receiving the first electronic file for comparison,

receiving the second electronic file for comparison,

comparing the first electronic file with the second electronic file, and

generating information for displaying, within the comparison output, differences between the first electronic file and the second electronic file.

57. A computer-based system for indicating non-matched annotations within files comprising:

a memory storing instructions; and

a processor configured to execute the instructions to;

identify a first annotation in a first electronic file;

identify a second annotation in a second electronic file;

generate an index including;

first annotation content corresponding to the first annotation,

a first annotation location corresponding to the first annotation,

second annotation content corresponding to the second annotation, and
