warning Your IBM Cloud open_in_new account must be configured to allow use of the Natural Language Classifier service open_in_new in order to use this BLOCK. You must also have Natural Language Classifier service credentials.

This BLOCK allows you to use Classify from the IBM Watson Natural Language Classifier API open_in_new from BLOCKS.

With this BLOCK, you can use a trained classifier to analyze untrained text and classify its intent (② in the image below). It classifies the data as the most appropriate class from among the ones set during the training.

The following example shows the results of classifying the sentence, “Today is cold, isn’t it?”

{
  "classifier_id": "e55175x249-nlc-51930",
  "text": "Today is cold, isn’t it?",
  "top_class": "temperature",
  "classes": [
    {
      "class_name": "temperature",
      "confidence": 0.9733634159663508
    },
    {
      "class_name": "conditions",
      "confidence": 0.026636584033649123
    }
  ]
}

• "top_class": The class with the highest confidence score.
• "classes": A list of all classes ordered from highest to lowest "confidence" score.
