Question 3
What is an approach for integrating a database into an IBM Watson solution?
- Use the Discovery service to search through candidate queries and surface the ones most relevant to the user input.
- Use the Document Conversion service to search the database for the entries with the strongest relationship to the user input.
- Use the intent from the Natural Language Classifier as part of a query.
- Use the concepts from Natural Language Understanding to search the database for the most relevant documents.

Question 8
When is it appropriate to include multiple classes for a sample text in the training data for IBM Watson Natural Language Classifier?
- When text is very detailed such that identifying a single class may cause inaccuracies.
- When experts interpret the same text in different ways, multiple classes support those interpretations.
- When the text utterances are very similar in nature and we want to mark slight differences using classes
- When the classifier has been retrained and we want to preserve old classes from a previous training set.
Correct answer: B

Question 9
How are language preferences set for IBM Watson Natural Language Classifier (NLC)?
- The NLC can automatically detect the language of the incoming request.
- A language parameter is specified as a part of every call to the classifier.
- There are no options to do this as the NLC works only on English language utterances.
- The language parameter is specified in the training meta data file when creating a classifier.
Correct answer: D
Question 10
