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_tokenizefunction - A frequency distribution object is created using the
FreqDistfunction - The program prints the five most common words and their frequency using the
most_commonmethod
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.Textobject is created - The
generatemethod 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
WordNetLemmatizerandword_tokenizeclasses 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
ngramsfunction 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)
