NLTK Tokenize: Tokenize sentences in languages other than English
NLTK Tokenize : Exercise-2 with Solution
Write a Python NLTK program to tokenize sentences in languages other than English.
Sample Solution:
Python Code :
text =
'''
NLTK ist Open Source Software. Der Quellcode wird unter den Bedingungen der Apache License Version 2.0 vertrieben.
Die Dokumentation wird unter den Bedingungen der Creative Commons-Lizenz Namensnennung - Nicht kommerziell - Keine
abgeleiteten Werke 3.0 in den Vereinigten Staaten verteilt.
'''
print("\nOriginal string:")
print(text)
from nltk.tokenize import sent_tokenize
token_text = sent_tokenize(text, language='german')
print("\nSentence-tokenized copy in a list:")
print(token_text)
print("\nRead the list:")
for s in token_text:
print(s)
Sample Output:
Original string: NLTK ist Open Source Software. Der Quellcode wird unter den Bedingungen der Apache License Version 2.0 vertrieben. Die Dokumentation wird unter den Bedingungen der Creative Commons-Lizenz Namensnennung - Nicht kommerziell - Keine abgeleiteten Werke 3.0 in den Vereinigten Staaten verteilt. Sentence-tokenized copy in a list: ['NLTK ist Open Source Software.', 'Der Quellcode wird unter den Bedingungen der Apache License Version 2.0 vertrieben.', 'Die Dokumentation wird unter den Bedingungen der Creative Commons-Lizenz Namensnennung - Nicht kommerziell - Keine abgeleiteten Werke 3.0 in den Vereinigten Staaten verteilt.'] Read the list: NLTK ist Open Source Software. Der Quellcode wird unter den Bedingungen der Apache License Version 2.0 vertrieben. Die Dokumentation wird unter den Bedingungen der Creative Commons-Lizenz Namensnennung - Nicht kommerziell - Keine abgeleiteten Werke 3.0 in den Vereinigten Staaten verteilt.

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")
