Sean Talking Bot
I have been working o an adaption of Eliza (from python's NLTK package) to make a bot that responds to spam emails.
There are several changes/addition like to make:
- crafting more carefully the patterns that the bot (Sean) responds to and answers give TODO
- changing the pronouns of the input to the proper pronoun in the output: I <-> you; mine <-> yours, etc
eg: IN: I need your help. OUT: Would it really help you to get my help?
- include salutations and farewells TODO

How is it working?
the vocabulary file contains tuple pairs: (regex, possible replies)
eg: (r'Why (.*)', ( "Why don't you tell me the reason why %1?", "Why do you think %1?" )), #regex will select from 'Why are you happy?' the string 'are you happy?'
- a loop cycles through those tuples trying to find the which regex yield matchs; and adds them to found_pairs list
- from the results 1 is selected
- from that 1 result 1 possible answer is chosen
- if it allows substitution ( %1 ):
- the gramatical person of the input is changed (in the change_subject function)
- the found match (found_pairs[1]) replaces 1%
- we get sean's reply
