Computerized Clinical Decision Support (CDS) aims to aid decision making relating to the health care providers and the public. It provides a mechanism involving easy accessibility of health-related information at any point and time, when needed. Natural Language Processing (NLP) is instrumental in using free-text information stored in database over cloud to drive CDS. Thus, representing clinical knowledge and CDS interventions in standardized formats, which is widely acceptable and understood by everyone. The early innovative NLP research of clinical narrative was followed by a period of stable research conducted at the major clinical centers and a shift of mainstream interest to biomedical NLP. This review focuses on the recently renewed interest in development of fundamental NLP methods and widely available cloud environment, which will provide intuitive features to its
