Question 2

Multiple Choice

Which of the following statements is false?


A) An xe "n-grams"n-gram is a sequence of n text items, such as letters in words or words in a sentence. In natural language processing, n-grams can be used to identify letters or words that frequently appear adjacent to one another.
B) For text-based user input, n-grams can help predict the next letter or word a user will type-such as when completing items in IPython with tab-completion or when entering a message to a friend in your favorite smartphone messaging app. For speech-to-text, n-grams might be used to improve the quality of the transcription.
C) You can pass the keyword argument n to TextBlob's ngrams method to produce n-grams of any desired length.
D) The following code uses TextBlob's ngrams method to create all the trigrams from a sentence. The code is actually incorrect-it should have used the keyword argument n=3 to TextBlob's ngrams method:
In [1]: from textblob import TextBlob
In [2]: text = 'Today is a beautiful day. Tomorrow looks like bad weather.'
In [3]: blob = TextBlob(text)
In [4]: blob.ngrams()
Out[4]:
[WordList(['Today', 'is', 'a']) ,
WordList(['is', 'a', 'beautiful']) ,
WordList(['a', 'beautiful', 'day']) ,
WordList(['beautiful', 'day', 'Tomorrow']) ,
WordList(['day', 'Tomorrow', 'looks']) ,
WordList(['Tomorrow', 'looks', 'like']) ,
WordList(['looks', 'like', 'bad']) ,
WordList(['like', 'bad', 'weather']) ]
