VaderSharp. The best sentiment analysis tool. In C#.
“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 is built on .NET Standard v1.6. As such it should work across any variant of the .NET framework, as long as you’re running the most up-to-date version.
To install VaderSharp, run the following command in the Package Manager Console:
Import the package at the top of the page:
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);
