vadersharp's Introduction

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.

Getting Started

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

Usage

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);

SentimentUtils: Separate data and logic

I would recommend to write all constants, words and other Information in ressource files, e.g. JSON or XML. That would support a more strict separation of data and logic. Furthermore, it simplifies i18n.

What license is this under?

As per title, please specify the license.

Multi Target Framework Support

This is a very nice library.

Please consider adding support for other frameworks or at the minimum a version of the full framework e.g. net40 or net452. At the moment I cannot use your NuGet anywhere other than where netstandard1.6 is supported.

FYI, you can take a look at some of my repositories (THIS or THIS) on how to enable multi target framework support in NuGet.

Alternatively let me know and I will be happy to send over a pull request.

Include the XML documentation in the NuGet package

At the moment the XML documentation for the public members and types are not included in the NuGet package.

As part of #8 This can be added.

FormatException: Input string was not in a correct format.

For your information your component is crashing right at initialization:

SentimentIntensityAnalyzer analyzer = new SentimentIntensityAnalyzer();

System.TypeInitializationException: 'The type initializer for 'VaderSharp.SentimentIntensityAnalyzer' threw an exception
