Soenneker.Utils.Strings.DiceCoefficient

Sørensen–Dice string similarity using overlapping character bigrams.

Installation

dotnet add package Soenneker.Utils.Strings.DiceCoefficient

Usage

using Soenneker.Utils.Strings.DiceCoefficient;

var text1 = "This is a test";
var text2 = "This is another test";

double score = DiceCoefficientStringUtil.Calculate(text1, text2);
double percentage = DiceCoefficientStringUtil.CalculatePercentage(text1, text2);

// score == 0.75
// percentage == 75

For each input, the utility creates overlapping two-character sequences and compares them as a multiset. Repeated bigrams therefore count up to the number present in both inputs. The coefficient is:

2 × shared bigram count / total bigram count across both inputs

Calculate returns a value from 0 to 1; CalculatePercentage multiplies it by 100.

Comparison rules

Comparison is case-sensitive.
Bigrams consist of adjacent UTF-16 code units.
Whitespace and punctuation participate like any other character.
Order inside each bigram matters, while the order of the resulting bigram collection does not.
Two empty strings return 1; one empty input returns 0.
Inputs shorter than two characters return 1 only when they are exactly equal, otherwise 0.

Call the static methods directly; no dependency-injection registration is required. Normalize casing, whitespace, punctuation, or Unicode representation before calling if your application needs those equivalences.

The implementation allocates a frequency dictionary for the shorter input and scans the longer input once, making it suitable for ordinary fuzzy matching and duplicate-candidate ranking. It is lexical comparison, not semantic similarity.
