Any workaround for finding the texts including symbols such as '(' and ')' ?

[shivam1702]

The algorithm breaks when it enounters these symbols. Here is the error it displays:
bash: syntax error near unexpected token '('

I'm not sure I understand the issue. I tried the algorithm with text that contains '(' and ')' and it seemed to work fine. Please, can you provide examples of what you are trying to do? Maybe upload the text file so I can try it with that?

Just change the encoding type to UTF-8 by inserting the following lines in your textrank.py file in usr/local/bin or wherever it is installed:
import sys
reload(sys)
sys.setdefaultencoding('utf8')

And the code will run properly.
