An Efficient Information Retrival Algorithm for Federated Healthcare Medication System

Cloud infrastructure is deployed in healthcare to access various healthcare services over the Internet. Healthcare cloud is used as a tool for patients to query the best medical departments, organizations and other healthcare related hubs. There may exist various service providers corresponding to a specific healthcare service. The major goal is to find the providers that meet with patients’ (users) requirement. In this paper, we propose and analyze the efficient algorithms to comply the natural language statements to a query based format to support the patients’ healthcare service accessibility with minimum time complexity. The requirements are captured in natural language through a user-interface and then processes the input query through the proposed efficient algorithms and finds all possible services satisfying the requirements. The whole system has been implemented by using DOT-NET and mySQL. The system is evaluated with initial test case on synthetic and real life healthcare cloud.
