I am building a chatbot and I need corpora to train them. I need corpora that is used as general chatting. I would be happy if anyone would help me with it.
Project Gutenberg has some of the largest free open-source corpora available (in multiple languages). You can download as much or as little as you wish in a variety of formats. A clever chatbot can quote back lines from Shakespeare or Dickens perhaps. http://www.gutenberg.org/
Here is a dataset of IRC chats: http://chatlogs.planetrdf.com/swig/. This is probably what you need.
