One crucial layer of the ARE4 system is our Confidence Scoring Engine. Here, the system analyzes the physician’s level of certainty or confidence of her report. This is done using machine learning, artificial intelligence and statistical algorithms.
Each concept is examined for the confidence level of the physician making the report. An overall confidence level is determined via our proprietary statistical analysis and artificial intelligence software components.
There are hundreds of such common phrases that can color the results and no true natural language understanding can exist without taking this critical concept of sentiment into account.
Many medical reports are filled with such language. Here are a few more examples: “most likely, could be, suggestive, resembles, indeterminate, appears, may represent, possible, and consistent with.”
The pie chart shows the proportion of medical reports that are either clear cut (presence/absence) or have some degree of hedging.
We break the language into “for sure” hedging (“yes”) and “maybe” hedging. It’s consistently about 20% of the medical report total, a signficant amount.
