Health conversational system based on contextual matching of community-driven question-answer pairs

More and more people are turning to the World Wide Web for learning and sharing information about their health us- ing search engines, forums and question answering systems. In this demonstration, we look at a new way of deliver- ing health information to the end-users via coherent con- versations. The proposed conversational system allows the end-users to vaguely express and gradually refine their in- formation needs using only natural language questions or statements as input. We provide example scenarios in this demonstration to illustrate the inadequacies of current de- livery mechanisms and highlight the innovative aspects of the proposed conversational system.
