US 10,649,985 B1 · Systems and methods for processing natural language queries for healthcare data

Abstract

In some embodiments of the present disclosure, techniques are utilized that allow answers to be provided to end users such as health care consumers, based on benefit book documents. The benefit book documents, which do not initially contain machine-readable structural or semantic information, are processed in order to detect structure and create semantic content based on the structure. This semantic content may then be added to a graph that represents the information contained in the benefit book document. A computing device may then use the nodes of this graph to answer questions received from consumers, where templates that provide answers to the questions reference the nodes of the graph.

Dependent claims

A computer-implemented method of enabling one or more computing devices of a healthcare information system to retrieve information from a benefit book document that represents healthcare benefit information in, response to a query, the method comprising:

generating, by a computing device, a set of structure tags that mark structures within the benefit book document;
determining, by a computing device, a set of semantic tags associated with the benefit book document using the set of structure tags and one or more of string matching, format matching, or page placement matching;
building, by a computing device, a graph of information in the benefit book document using the semantic tags;
determining, by a computing device, an intent associated with a query for information contained in the benefit book document;
matching, by a computing device, the intent to a template, the template including a reference to a value in the graph of information;
and
transmitting, by a computing device, a response to the query that includes the value from the benefit book document as indicated by the graph of information.

4 more elements

A healthcare information system comprising one or more computing devices configured to process benefit book documents that represent healthcare benefit information in order to respond to queries, by:

generating, by a computing device, a set of structure tags that mark structures within a benefit book document;
determining, by a computing device, a set of semantic tags associated with the benefit book document using the set of structure tags and one or more of string matching, format matching, or page placement matching;
building, by a computing device, a graph of information in the benefit book document using the semantic tags;
determining, by a computing device, an intent associated with a query for information contained in the benefit book document;
matching, by a computing device, the intent to a template, the template including a reference to a value in the graph of information;
and
transmitting, by a computing device, a response to the query that includes the value from the benefit book document as indicated by the graph of information.

4 more elements

A non-transitory computer-readable medium having computer-executable instructions stored thereon that, in response to execution by one or more processors by one or more computing devices of a healthcare information system, cause the healthcare information system to process benefit book documents that represent healthcare benefit information in order to respond to queries, by:

generating, by a computing device, a set of structure tags that mark structures within a benefit book document;
determining, by a computing device, a set of semantic tags associated with the benefit book document using the set of structure tags and one or more of string matching, format matching, or page placement matching;
building, by a computing device, a graph of information in the benefit book document using the semantic tags;
determining, by a computing device, an intent associated with a query for information contained in the benefit book document;
matching, by a computing device, the intent to a template, the template including a reference to a value in the graph of information;
and
transmitting, by a computing device, a response to the query that includes the value from the benefit book document as indicated by the graph of information.
