Much clinical information, such as age and gender, is available in structured formats. But often, the information that can tell doctors the most about a patient's condition is in unstructured formats. This includes patients’ free-text clinical notes (e.g., nursing notes, lab reports, and radiology reports), which are generally difficult and time-consuming to analyze. A critica...l part of providing personalized medicine is being able to efficiently use this unstructured data to provide clinical insights.
Intel® Distribution for Apache Hadoop* software, GraphBuilder*, and GraphLab* are distributed computation frameworks that make it possible to analyze free-text clinical notes in a scalable, efficient way. Both Intel Distribution for Apache Hadoop software and GraphBuilder rely on the independence among patients’ records to provide a data-parallel solution for preprocessing, formatting, and normalization. GraphLab uses the dependencies in post-processed records to derive meaningful insights in a parallel way. Together, these technologies can help alleviate the bottleneck of creating topic models documented in the research article "Topic Models for Mortality Modeling in Intensive Care Units.”
