University Auto Reply FAQ Chatbot Using NLP and Neural Networks

Abstract

When new students enter college, they often have similar questions - ”Where to study for this subject?”, ”How to prepare Data Struc- tures and Algorithms?”, ”How to connect with seniors?” and so on. The use of chatbots can help them get answers to their questions quickly and efficiently. This study proposes a Deep Learning (DL) chatbot for addressing common doubts of university students, pro- viding efficient and accurate responses to college-specific questions. A self-curated dataset is used for the purpose of building the chat- bot and natural language processing techniques (NLP) are utilized for the pre-processing of raw data gathered. The study compares two deep learning models - a bidirectional Long Short Term Memory (LSTM) network and a simple feed-forward neural network model.
