Probabilistic event classification systems and methods
First Claim
1. A method for classifying a safety event occurring in a healthcare setting using a classification system comprising an intelligent probabilistic event classification server having a hardware processor and a memory for storing executable instructions, the hardware processor being configured to execute the instructions to perform the method, comprising:
- receiving on an interactive graphical user interface an event narrative, the event narrative comprising textual content describing a safety event;
parsing the textual content to identify key terms,the parsing comprising generating tokens from the event narrative by the hardware processor selecting a plurality of frequently-appearing tokens, the frequently-appearing tokens being tokens that appear most frequently in the event narrative,the parsing further comprising calculating, for the event narrative, a probability for each of a plurality of classifications based on the frequently-appearing tokens, each frequently-appearing token having a corresponding probability for a classification and representing an interesting token,the interesting token improving confidence and improving performance of the hardware processor of the intelligent probabilistic event classification server;
selecting a set of classifications, the set of classifications comprising potential event types for the event narrative, the selecting the set of classifications being based on the calculated probabilities;
the calculating probabilities comprising;
determining a number (NT) of occurrences of the token occurring in classified event narratives having a classification;
determining a number (NE) of classified event narratives having the classification;
determining a number (MT) of occurrences of the token relative to the classified event narratives not having the classification;
determining a number (ME) of events not associated with the classification; and
calculating a probability that a token is associated with a classification by;

Abstract
Probabilistic event classifications systems and method are provided herein. In one embodiment, a method includes receiving an event narrative, the event narrative comprising textual content describing a safety event, parsing the textual content to identify key terms, searching a safety event database for classifications associated with the key terms, selecting a set of classifications based on the key terms using statistical analysis, the set of classifications comprising potential event types for the event narrative, and displaying the set of classifications for the event narrative via a graphical user interface.
