Adjusting Comparison Sensitivity Leave feedback

GroupDocs.Comparison for Python via .NET supports comparison sensitivity values from 0 (fastest, least detailed) to 100 (slowest, most detailed). The default is 75.

• 0 — fastest comparison; only fully-disjoint substrings are detected as inserts/deletes.
• 75 — the default. Sub-sequences that have more than 75% of their content inserted or deleted are treated as fully inserted or deleted.
• 100 — slowest comparison; any common sub-sequence is taken into account.

Consider these two strings:

They share two common sub-sequences: the word is and three space characters. The common sub-sequence is " is " (length 4 including spaces). The inserted sub-sequence is Jackagladcalf (length 13). The removed sub-sequence is Itourequitypoetry (length 17). The percentage of removed and inserted symbols is (17 + 13) / (17 + 13 + 4) * 100 = 88%.

• sensitivity_of_comparison = 80 — 88% > 80%, so the common sub-sequence is discarded. Result: Jack is a glad calfIt is our equity poetry (the first string is fully removed, the second fully inserted).
• sensitivity_of_comparison = 89 — 88% < 89%, so the common sub-sequence is kept. Result: JackIt is aour gladequity calfpoetry.

Increase sensitivity to detect smaller changes; lower it for faster processing.

Use case: maximise accuracy for legal or scientific documents where subtle edits matter.

Tables can have their own sensitivity value, independent of the overall setting:

from groupdocs.comparison import Comparer
from groupdocs.comparison.options import CompareOptions

def adjust_comparison_sensitivity_tables():
    with Comparer("./source.docx") as comparer:
        comparer.add("./target.docx")
        options = CompareOptions()
        options.sensitivity_of_comparison = 100
        options.sensitivity_of_comparison_for_tables = 75
        comparer.compare("./result.docx", options)

if __name__ == "__main__":
    adjust_comparison_sensitivity_tables()

Use case: tune detection granularity in tables while keeping overall sensitivity high.
