   The IBM Watson™ Natural Language Classifier service applies deep learning techniques to make predictions about the best predefined classes for short sentences or phrases. The classes can trigger a corresponding action in an application, such as directing a request to a location or person, or answering a question. After training, the service returns information for texts that it hasn't seen before. The response includes the name of the top classes and confidence values.

-Sample web applications that include this package may be configured to track deployments to [IBM Bluemix](https://www.bluemix.net/) and other Cloud Foundry platforms. The following information is sent to a [Deployment Tracker](https://github.com/IBM-Bluemix/cf-deployment-tracker-service) service on each deployment:
-
-* Node.js package version
-* Node.js repository URL
-* Application Name (`application_name`)
-* Space ID (`space_id`)
-* Application Version (`application_version`)
-* Application URIs (`application_uris`)
-* Labels of bound services
-* Number of instances for each bound service and associated plan information
-
-This data is collected from the `package.json` file in the sample application and the `VCAP_APPLICATION` and `VCAP_SERVICES` environment variables in IBM Bluemix and other Cloud Foundry platforms. This data is used by IBM to track metrics around deployments of sample applications to IBM Bluemix to measure the usefulness of our examples, so that we can continuously improve the content we offer to you. Only deployments of sample applications that include code to ping the Deployment Tracker service will be tracked.
