EmotionAnalyzer

public class EmotionAnalyzer

Class to extract the sentiments from a text.

It is a good idea to test that the model is loaded before calling analyze(). A simple use case to analyze a text for prevalent emotions would be:

func classifyText(text: String) -> EmotionResult? {
    if (EmotionAnalyzer.sharedInstance().isLoaded()) {
        return EmotionAnalyzer.sharedInstance().analyze(text: text)
    }
    return nil
}

  • Class function to get the single instance of this class.
