What is the purpose of the IBM Watson Natural Language Classifier service?
Interpret the intent behind text and returns a corresponding classification with associated confidence levels
Reduce the number of random utterances consideration, by obtaining a set of uncorrelated utterances
Translate a natural language sentence into a syntactic representation such as a parse tree
Group a set of objects in such a way that objects in the same group are more similar to each other than to those in other groups
Correct answer: A
Explanation:
IBM Watson Natural Language Classifier is a service that enables developers without a background in machine learning or statistical algorithms to create natural language interfaces for their applications, interprets the intent behind text and returns a corresponding classification with associated confidence levels and the return value can then be used to trigger a corresponding action, such as redirecting the request or answering a question.

Explanation:
Question 3
What are two advantages gained by using IBM Cloud as the application platform for an application using Watson services? (Choose two.)
IBM Cloud is built on proprietary APIs which provide competitive advantages
The IBM Cloud application developer can choose among multiple release versions of the Cloud Foundry framework
IBM Cloud promotes 12-factor methodology since IBM Cloud is deployed exclusively as a public cloud model
Environmental, operational, and functional Security are built into the IBM Cloud platform
Scaling application capacity is simple for applications following modern design (such as 12-factor methodology)
