  • To generate n-grams from a list of tokens with a specified value of n (correct)
  • To tokenize the input text into words

    • What is the purpose of the generate_ngrams() function?

  • To print the generated n-grams
  • To generate n-grams from the input text and store them in a list (correct)
  • To tokenize the input text into words
  • To smooth the generated n-grams

    • What is the purpose of the word_tokenize() function from the nltk module?

  • To convert the input text into a list of words (tokens) (correct)
  • To generate n-grams from a list of tokens
  • To smooth the generated n-grams
  • To print the generated n-grams

    Study Notes

    Word Analysis in Python

    • The program uses NLTK library for word analysis
    • It prompts the user to enter a sentence or text for analysis
    • The input text is tokenized using the word_tokenize function
    • A frequency distribution object is created using the FreqDist function
    • The program prints the five most common words and their frequency using the most_common method

    Word Generation in Python

    • The program generates text based on user input
    • It prompts the user to enter a text and the number of words to generate
    • The input text is tokenized and an nltk.Text object is created
    • The generate method is used to generate text with the specified length
    • The generated text is printed to the console

    Morphology in Python

    • The program uses NLTK library for morphology
    • The WordNet corpus is downloaded using nltk.download
    • The WordNetLemmatizer and word_tokenize classes are imported from NLTK
    • The program prompts the user to enter a sentence and lemmatizes each token
    • The lemmatized tokens are printed to the console

    N-Grams in Python

    • The program generates n-grams from user input
    • The ngrams function is used to generate n-grams from tokenized text
    • The program prompts the user to enter a text and the value of n for n-gram generation
    • The generated n-grams are printed to the console

    N-Gram Smoothing in Python (Note: The text does not provide a program for n-gram smoothing)
