Intelligent-Chatbot

A chatbot is an intelligent piece of software that is capable of communicating and performing actions similar to a human. Chatbots are used a lot in customer interaction, marketing on social network sites and instantly messaging the client. Our chatbot is a COVID CHATBOT. The primary focus of the bot is to guide people in the ongoing pandemic, answer questions regarding vaccinations, symptoms, live covid statistics, probability of being infected to name a few.

To run the chatbot locally: python3 chatgui.py

chatgui.py contains the GUI of the chatbot using which the user can interact with the bot. Tkinter has been used to make this.

Training of the Chatbot

• Run python3 train_chatbot.py in the terminal to train the chatbot.
  • words.pkl, classes.pkl and chatbot_model.h5 will be generated.
  • words.pkl stores the the words Python object that contains a list of our vocabulary, classes.pkl contains the categories and chatbot_model.h5 contains the trained model that contains information about the model and has weights of the neurons.
• We have trained our chatbot using the keras module andnltk wordnets to the intents.json present in the Data folder.
• A special recurrent neural network (LSTM) is used to classify which category the user’s message belongs to and then we will give a random response from the list of responses.

Functionalities

Probability of being infected

An existing dataset (https://github.com/nshomron/covidpred) was used to collect data regarding 7 features and the state of the patient(i.e. if she/he has COVID or not). Using the data, a Naive Bayes Classifier from the sklearn module was trained in order to predict new cases of COVID. The user is asked to input the details in a specific format after which the classifier predicts probability of the user having COVID.
