The current rural medical information construction is still imperfect. Large amount of medical data related to common rural disease is used at very low utilization rate. In order to improve the utilization of these data and to provide help for rural barefoot doctors and rural residents, we developed a distributed implied semantic text retrieval model and improved the weight calculation formula of the implied semantic text retrieval based on implied semantic text retrieval and distributed computing technology. The experiment results indicate that our retrieval framework can shorten the time of text retrieval and improve the accuracy of text retrieval.
