Demo Questions

Question 1
What is the purpose of the IBM Watson Natural Language Classifier service?
  1. Interpret the intent behind text and returns a corresponding classification with associated confidence levels
  2. Reduce the number of random utterances consideration, by obtaining a set of uncorrelated utterances
  3. Translate a natural language sentence into a syntactic representation such as a parse tree
  4. 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.
