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

Explanation:

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

Explanation:
