ViveknSentimentModel
Companion object ViveknSentimentModel
class ViveknSentimentModel extends AnnotatorModel[ViveknSentimentModel] with HasSimpleAnnotate[ViveknSentimentModel] with ViveknSentimentUtils
Sentiment analyser inspired by the algorithm by Vivek Narayanan https://github.com/vivekn/sentiment/.
The algorithm is based on the paper "Fast and accurate sentiment classification using an enhanced Naive Bayes model".
This is the instantiated model of the ViveknSentimentApproach. For training your own model, please see the documentation of that class.
The analyzer requires sentence boundaries to give a score in context. Tokenization is needed to make sure tokens are within bounds. Transitivity requirements are also required.
For extended examples of usage, see the Examples and the ViveknSentimentTestSpec.
