Natural Language Processing, or NLP is the process in which meaning is extracted from human language. In more general terms NLP allows systems to understand and comprehend language. Being able to do so enables the machine to interpret and understand human language. Leveraging this capability within the medical field can help and complement many things. None more so than the overall patients well-being. A quick example of this is where NLP is used to identify potential health risk problems for our patient by examining their historical clinical records. 

To support this Amazon now provides a specialized version of their Amazon Comprehend service called Amazon Comprehend Medical. Amazon Comprehend Medical is a service which provides medical NLP services leveraging pretrained state of the art deep learning models. Amazon maintains the underlying machine learning models, meaning you don't need to build and train your own and this is a big positive. Using the Amazon Comprehend Medical service, you can extract and identify many medical and healthcare related attributes contained within any unstructured medical text files and/or documents. Some such examples being, medications, medical conditions, treatment and procedures, anatomy and protected health information, or PHI. When examining unstructured medical notes, you leverage the Detect Entities and Detect PHI text analysis APIs. This can be done either by using the AWS CLI and/or the SDK. 

Relationships between extracted medical data attributes can be identified automatically resulting in faster diagnosis and in turn quicker treatment decisions, recovery and rehabilitation. Once the analysis has been completed, jump into the AWS Management Console and open up the Comprehend Medical Console. Here you can examine the relationships detected. The generated visualizations show relationships between medical entities highlighted by connections and color encoding techniques to differentiate the different types of medical entities. Amazon Comprehend Medical has been seamlessly integrated into other existing AWS services such as Amazon S3 and AWS Lambda. This allows you to quickly roll out customized solutions that encompass and enhance clinical information gathering and processing capabilities. If you're looking for a solution that provides medical NLP analysis then Amazon Comprehend Medical is that solution.
