Ai chatbot framework that based on text similarity model. to help answering complex medical questions. the chatbot system implements a novel text representation and similarity deep learning model, Hierarchical BiLSTM Attention Model (HBAM),to find the most similar question from a large QA dataset. We train and test the models with a subset of the Quora duplicate questions dataset in the medical area. The experimental results show that our model is able to achieve a superior performance than these existing methods.
