Sentiment Analysis

Learn how to understand the sentiment of a message.

The Sentiment Analysis extension helps you to understand the sentiment of a message. A message can be classified into 4 categories- positive, neutral, negative and mixed. Along with these categories, we specify the confidence for that category, on a scale of 0 to 100.

"@injected": {
  "extensions": {
    "sentiment-analysis": {
      "sentiment": "positive",
      "sentiment_score": {
        "positive": 95,
        "neutral": 4,
        "negative": 0,
        "mixed": 0
      }
    }
  }
}

Using this information, you can show either a warning or drop the message completely. Here is how Twitter shows a message:

At the recipients' end, from the message object, you can fetch the metadata by calling the getMetadata() method. Using this metadata, you can fetch the sentiment of the message.

var metadata = message.getMetadata();
if (metadata != null) {
    var injectedObject = metadata["@injected"];
    if (injectedObject != null && injectedObject.hasOwnProperty("extensions")) {
        var extensionsObject = injectedObject["extensions"];
        if (extensionsObject != null && extensionsObject.hasOwnProperty("sentiment-analysis")) {
            var sentimentAnalysisObject = extensionsObject["sentiment-analysis"];
            var sentiment = sentimentAnalysisObject["sentiment"];
            if (sentimentAnalysisObject.hasOwnProperty("sentiment_score")) {
                var positive = sentimentAnalysisObject["positive"];
                var neutral = sentimentAnalysisObject["neutral"];
                var negative = sentimentAnalysisObject["negative"];
                var mixed = sentimentAnalysisObject["mixed"];
            }
        }
    }
}
