### A utility library for comparing strings via the Jaccard similarity algorithm

## Installation

```

dotnet add package Soenneker.Utils.String.JaccardSimilarity

```

## Why?

Jaccard similarity is great for comparing sets of items, and it's often used for tasks like detecting similar documents or recommending content. It's useful because:

### Set-Focused: 

It works well when you care about what elements are present, not their order.

### Scale Doesn't Matter: 

It's not influenced by how big the sets are, just by what they share.

### Efficient: 

It's quick to calculate making it suitable for large datasets.

### Handles Noise Well: 

It stays reliable even if there's extra, less important information in the sets.

## Usage

```csharp

var text1 = "This is a test";

var text2 = "This is another test";

double result = JaccardSimilarityStringUtil.CalculateSimilarityPercentage(text1, text2); // 60

```
