Finding a sense of word in a text

[Sengly]

Dear all,

This might be off group but I am looking for a python library that can
help me to find a sense of a word in a text and eventually a list of
synonyms of that term. I searched the web and found one but it is
written in perl (http://www.d.umn.edu/~tpederse/senserelate.html) :(

I appreciate any pointers.

Thank you before hand.

Kind regards,

Sengly
