ANALYSIS AND RULE GENERATION OF MEDICAL DOCUMENTS

摘要

This disclosure describes a computerized system for managing medical information, the system including at least one computing device configured to receive a plurality of medical documents, determine skip grams comprising tokens for the plurality of medical documents, wherein each of the skip grams comprises one or more tokens of at least one of the medical documents, and populate a trie data structure based on the skip grams. The at least one computing device is further configured to prune the plurality of nodes of the trie based on one or more criteria to produce a pruned trie of nodes, determine rules for associating medical billing codes with the skip grams of the pruned trie of nodes based on pointwise mutual information, and output the determined rules.

1. A computer-implemented method for managing medical information, the method performed by one or more processors of at least one computing device, the method comprising:
receiving, by the one or more processors, a plurality of medical documents; determining, by the one or more processors, skip grams comprising tokens for the plurality of medical documents, wherein each of the skip grams comprises one or more tokens of at least one of the medical documents; populating, by the one or more processors, a trie data structure based on the skip grams, wherein populating the trie comprises:
adding a null root node to the trie; andadding a plurality of nodes to the trie,wherein the plurality of nodes each have a parent node comprising either: the root node or another one of the plurality of nodes,
wherein each of the plurality of nodes comprises one of the determined skip grams,wherein, for every one of the plurality of nodes having a respective parent node, a skip gram of the one of the plurality of nodes has a greater size than a skip gram of the parent node of the one of the plurality of nodes; pruning, by the one or more processors, the plurality of nodes of the trie based on one or more criteria to produce a pruned trie of nodes; determining, by the one or more processors, rules for associating medical billing codes with the skip grams of the pruned trie of nodes based on pointwise mutual information; and outputting, by the one or more processors, the determined rules.
