"VADER (Valence Aware Dictionary and sEntiment Reasoner) is a lexicon and rule-based sentiment analysis tool that is specifically attuned to sentiments expressed in social media."
Previously VADER was only available in python (https://github.com/cjhutto/vaderSentiment). I wanted to use it in C# so ported it over.
VaderSharp supports:
- .NET Core
- .NET Framework 3.5 and above
- Mono & Xamarin
- UWP
To install VaderSharp, run the following command in the Package Manager Console:
Install-Package CodingUpAStorm.VaderSharp
Import the package at the top of the page:
using VaderSharp;
Then just initialize an instance of SentimentIntensityAnalyzer and call it's PolarityScores method:
SentimentIntensityAnalyzer analyzer = new SentimentIntensityAnalyzer();
var results = analyzer.PolarityScores("Wow, this package is amazingly easy to use");
Console.WriteLine("Positive score: " + results.Positive);
Console.WriteLine("Negative score: " + results.Negative);
Console.WriteLine("Neutral score: " + results.Neutral);
Console.WriteLine("Compound score: " + results.Compound);
