### A utility library for comparing strings via the Dice Coefficient algorithm

## Installation

```

dotnet add package Soenneker.Utils.Strings.DiceCoefficient

```

## Why?

The Dice Coefficient is a powerful way to measure similarity between strings or other sequences. It's particularly effective for comparing text fragments, identifying duplicates, and matching approximate content. Here's why it stands out:

### Pairwise Comparison:

It evaluates based on overlapping character pairs (bigrams), focusing on shared elements without considering their order.

### Balanced by Size:

It considers both the number of matches and the total size of the compared strings, ensuring a fair similarity measure.

### Suitable for Real-World Data:

Its sensitivity to shared sequences makes it effective for noisy or partially matching data.

### Fast and Scalable:

It's computationally efficient, making it applicable for large datasets or repeated comparisons.

## Usage

```csharp

var text1 = "This is a test";

var text2 = "This is another test";

double result = DiceCoefficientStringUtil.CalculatePercentage(text1, text2); // 74.07

```
