Abstract: The application of artificial intelligence, has penetrated all walks of life. In order to better combine the latest technology to help users quickly and accurately find the information they want, a framework of Knowledge Service System in Health Care field based on knowledge graph is proposed, which can be realized through the links of human-computer interaction, question parsing, FAQ problem matching, knowledge base query and reasoning, evaluation and recommendation of question and answer results, and forwarding of difficult questions. The design of this architecture is of great practical significance for the innovation of knowledge service system model under the background of new technology.
