Multiple Choice Questions (MCQ) in Natural Language Processing (NLP) with answers
MCQ Quiz Questions with Answers in NLP
1.
In an HMM, observation likelihoods measure
a)

b)
The likelihood of a POS tag given the preceding tag
c) The likelihood of a
word given a POS tag
d)

Answer: (c)

2.
Consider the language L = {anbncm | m, n
>=0}. Which of the following strings are in L?
a) abbc
b) ab
c) aabc
d) abbcc
Answer: (b)
As per the given
language, the number of a’s and b’s should be same in the resultant strings. In
that point of view, only (b) is correct. Here, n=1 and m=0.

3.
Which of the following instances the regular expression “\b(one|two|three)\b”
can recognize?
a) “one”
b) “onetwo”
c) “TWO”
d) All of the above
Answer: (a)
In the given regular
expression, ‘\b’ represents the word boundary and ‘|’ represents
alternatives. As a result, this regular expression can accept either ‘one’,
or ‘two’, or ‘three’ and nothing else.

4.
Which of the following can be used to implement orthographic rules?
a) Finite State Automata
(FSA)
b) Finite State Transducer (FST)
c) Hidden Markov Model
(HMM)
d) None of the above
Answer: (b)
Orthographic rules are
spelling rules. The addition of morpheme suffixes may sometime change the
spelling of the new word. For example, the plural of the word ‘fox’ is ‘foxes’.
We arrived at ‘foxes’ by concatenating ‘fox’ and ‘-s’ with an insertion of ‘e’
in between.
FSA only accepts or
rejects a word. That is, it can say ‘yes’ or ‘no’ for certain input on tapes.
But due to the change in spelling, we need an automaton that reads from one
tape and writes to the other. Hence, FST is the correct choice.

5.
The words ‘there’ and ‘their’ causes which of the following
type of ambiguity?
a) Syntactic
b) Semantic
c) Phonological
d) Pragmatic
Answer: (c)
Phonological ambiguity (phonetic ambiguity)
is a type of ambiguity that
arises out of the fact that words sound identical, but in fact have different
meanings.
