SentiScope – Text Sentiment Analyzer is a ready-to-use OutSystems extension that brings sentiment analysis directly into your applications using a fully integrated .NET library.
This component leverages VaderSharp, a .NET port of the VADER (Valence Aware Dictionary and sEntiment Reasoner) sentiment analysis algorithm. VADER is widely known for its accuracy in evaluating short, informal, and social media-style text, making this extension ideal for analyzing user comments, reviews, chat messages, and feedback forms.
