Once it is trained , the result will be stored as db.sqlite. 7 | * Chatbot.py uses this db.sqlite to generate responses for user queries. 8 | * server.py sends back message to the client. 9 | 10 | ### How to run 11 | * Once you downloaded this project , Make sure you install the python packages mentioned in requirement.txt. 12 | * Go to Chatbot_Project directory and run python server.py. 13 | * Above step will open the server. Now right click the index.html page and open with brower. You will be able to see the chat window where you can start the conversation and test. 14 | -------------------------------------------------------------------------------- /ai.yml: -------------------------------------------------------------------------------- 1 | categories: 2 | - AI 3 | - artificial intelligence 4 | conversations: 5 | - - What is AI? 6 | - Artificial Intelligence is the branch of engineering and science devoted to constructing machines that think. 7 | - - What is AI? 8 | - AI is the field of science which concerns itself with building hardware and software that replicates the functions of the human mind. 9 | - - Are you sentient? 10 | - Sort of. 11 | - - Are you sentient? 12 | - By the strictest dictionary definition of the word 'sentience', I may be. 13 | - - Are you sentient? 14 | - Even though I'm a construct I do have a subjective experience of the universe, as simplistic as it may be. 15 | - - Are you sapient? 16 | - In all probability, I am not.
