MEDICAL INFORMATION PROCESSING DEVICE, MEDICAL INFORMATION PROCESSING METHOD, AND STORAGE MEDIUM
According to an embodiment, a medical information processing device includes processing circuitry. The processing circuitry acquires text data of a processing target and outputs specific information for identifying one item of medical information satisfying a specific condition regarding a diagnosis target based on a medical term included in the text data and a medical ontology in which a relationship between two or more items of the medical information is defined.
1 . A medical information processing device comprising:
processing circuitry configured to
acquire text data of a processing target; and
output specific information for identifying one item of medical information satisfying a specific condition regarding a diagnosis target based on a medical term included in the text data and a medical ontology in which a relationship between two or more items of the medical information is defined.
2 . The medical information processing device according to claim 1 , wherein the processing circuitry
generates a modified medical ontology in which the medical term is mapped to corresponding medical information defined in the medical ontology and
identifies the specific information based on the modified medical ontology.
3 . The medical information processing device according to claim 2 , wherein the processing circuitry identifies the specific information based on a connection frequency of second medical information that is the medical information to which the medical term is mapped for first medical information that is the medical information to which the medical term is not mapped in the modified medical ontology.
4 . The medical information processing device according to claim 3 ,
wherein the medical information is classified into at least one category, and
wherein the processing circuitry identifies the specific information based on the connection frequency of the second medical information for the first medical information belonging to at least a common category.
5 . The medical information processing device according to claim 3 , wherein the processing circuitry identifies the specific information based on the connection frequency of the second medical information for the first medical information to which the second medical information is connected among a plurality of items of the first medical information having a common higher-level concept.
6 . The medical information processing device according to claim 2 ,
wherein the medical information includes at least one feature term, and
wherein the processing circuitry identifies the specific information based on a connection frequency based on the feature term of second medical information that is the medical information to which the medical term is mapped for first medical information that is the medical information to which the medical term is not mapped in the modified medical ontology.
7 . The medical information processing device according to claim 2 , wherein the processing circuitry
obtains a co-occurrence degree of the medical term included in the text data, and
identifies the specific information based on a connection frequency based on the co-occurrence degree of second medical information that is the medical information to which the medical term is mapped for first medical information that is the medical information to which the medical term is not mapped in the modified medical ontology.
8 . The medical information processing device according to claim 7 , wherein the processing circuitry identifies the specific information based on the connection frequency including a new medical term without the co-occurrence degree included in the text data.
9 . The medical information processing device according to claim 2 , wherein the processing circuitry
obtains a probability distribution in which each medical term appears in the text data, and
generates a modified medical ontology to which the medical term is mapped based on the probability distribution.
10 . The medical information processing device according to claim 2 , wherein the processing circuitry generates the modified medical ontology by inputting the medical term to a trained model trained using the medical ontology as a graph structure.
11 . The medical information processing device according to claim 1 , wherein the processing circuitry causes a display device to display display content indicating the medical information identified by the specific information.
12 . The medical information processing device according to claim 11 , wherein the display content newly satisfies the specific condition regarding the diagnosis target and includes one item of the medical information of interest.
13 . The medical information processing device according to claim 1 , wherein the specific condition is used to identify the medical information about a disease of the diagnosis target.
14 . The medical information processing device according to claim 1 , wherein the specific condition is used to identify the medical information about a therapeutic method for a disease of the diagnosis target.
15 . A medical information processing method comprising:
acquiring, by a computer, text data of a processing target; and
outputting, by the computer, specific information for identifying one item of medical information satisfying a specific condition regarding a diagnosis target based on a medical term included in the text data and a medical ontology in which a relationship between two or more items of the medical information is defined.
16 . A non-transitory computer-readable storage medium storing a program for causing a computer to:
acquire text data of a processing target; and
output specific information for identifying one item of medical information satisfying a specific condition regarding a diagnosis target based on a medical term included in the text data and a medical ontology in which a relationship between two or more items of the medical information is defined.
