NLTK corpus: Compare the similarity of two given verbs

NLTK corpus: Exercise-10 with Solution

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

Sample Solution:

Python Code :

from nltk.corpus import wordnet
print("\nComparing go anb return:")
v1 = wordnet.synset('go.v.01')
v2 = wordnet.synset('return.v.01')
print(v1.wup_similarity(v2))

print("\nComparing buy anb sell:")
v1 = wordnet.synset('buy.v.01')
v2 = wordnet.synset('sell.v.01')
print(v1.wup_similarity(v2))

print("\nComparing begin anb start:")
v1 = wordnet.synset('begin.v.01')
v2 = wordnet.synset('start.v.01')
print(v1.wup_similarity(v2))

Sample Output:

Comparing go anb return:
0.6666666666666666

Comparing buy anb sell:
0.2857142857142857

Comparing begin anb start:
1.0

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")
