A Graph Based Chatbot for Cancer Patients

World Health Organization (WHO) reports that, the second major cause of death is cancer. Life of people who have cancer is daunting. Their heart is open to all negative emotions like anger, fear, depression, guilt, helplessness, etc. People around them are also finding it difficult to cope with it. They require constant support to discuss their problems with and to provide them with factual information. This paper introduces a potential solution to provide them with what they are seeking for- a chatbot. The proposed chatbot is a cancer chatbot designed only for people dealing with cancer. People can ask about anything and everything about cancer- symptoms, treatments, survival and so on. The bot is trained by information collected from various cancer forums which have a wide range of information about cancer. Sentiment analysis is used to identify the mood of the users so that the bot can give a human-like behavior and comfort them.
