NLTK corpus: Compare the similarity of two given nouns

NLTK corpus: Exercise-9 with Solution

Write a Python NLTK program to compare the similarity of two given nouns.

Sample Solution:

Python Code :

from nltk.corpus import wordnet
print("\nComparing ship anb boat:")
n1 = wordnet.synset('ship.n.01')
n2 = wordnet.synset('boat.n.01')
print("\nComparing bus anb boat:")
print(n1.wup_similarity(n2))
n1 = wordnet.synset('bus.n.01')
n2 = wordnet.synset('boat.n.01')
print(n1.wup_similarity(n2))
print("\nComparing red anb greed:")
n1 = wordnet.synset('red.n.01')
n2 = wordnet.synset('green.n.01')
print(n1.wup_similarity(n2))

Sample Output:

Comparing ship anb boat:

Comparing bus anb boat:
0.9090909090909091
0.7

Comparing red anb greed:
0.875

Python: Tips of the Day

Find current directory and file's directory:

To get the full path to the directory a Python file is contained in, write this in that file:

import os 
dir_path = os.path.dirname(os.path.realpath(__file__))

(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)

To get the current working directory use

import os
cwd = os.getcwd()

Documentation references for the modules, constants and functions used above:

  • The os and os.path modules.
  • The __file__ constant
  • os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
  • os.path.dirname(path) (returns "the directory name of pathname path")
  • os.getcwd() (returns "a string representing the current working directory")
  • os.chdir(path) ("change the current working directory to path")
