Abstract

A problem to be solved is to assist input of information by a user. An information processing device of one embodiment includes a keyword sequence generator generating a keyword sequence by performing morphological analysis on text data in natural language; a category information sequence generator acquiring category information corresponding to each keyword of the keyword sequence based on a database in which keywords are associated with category information and generating a category information sequence; the pattern extractor selecting a category information sequence pattern from category information sequence patterns according to correlation between the category information sequence and each category information sequence pattern; and a determiner comparing the selected category information sequence pattern with the category information sequence and generating presentation information according to a difference between the selected category information sequence pattern and the category information sequence.

First claim

The invention claimed is:

1. An information processing device comprising one or more computer processors configured to:
generate a keyword sequence by performing morphological analysis on text data in natural language wherein the text data is obtained by performing voice recognition processing on data indicating speech content by a user wherein the speech content is relating to a patient or a person who is cared for;
based on a database including keywords and category information associated therewith, acquire category information corresponding to each keyword of the keyword sequence to generate a category information sequence;
select a category information sequence pattern from a plurality of category information sequence patterns according to correlation between the category information sequence and each category information sequence pattern;
compare the selected category information sequence pattern with the category information sequence and generate presentation information according to a difference between the selected category information sequence pattern and the category information sequence;
output an input screen including a field for input of a value associated with a predetermined state of the patient or the person who is cared for, to a display device;
detect a keyword matching a term expressing the predetermined state from the keyword sequence, and based on a template associating the term with a position condition, extract a keyword located at a position satisfying the position condition for the detected keyword, from the keyword sequence, and
set the extracted keyword in the field of the input screen as the value associated with the predetermined state.

2. The information processing device according to claim 1 , wherein the one or more computer processors are configured to:
output the presentation information to the display device.

3. The information processing device according to claim 1 , wherein the one or more computer processors are configured to:
calculate a similarity between the category information sequence and each of the plurality of category information sequence patterns and select the category information sequence pattern based on the similarity.

4. The information processing device according to claim 1 ,
wherein the presentation information specifies category information which is included in the selected category information sequence pattern and which is not included in the category information sequence.

5. The information processing device according to claim 1 ,
wherein the presentation information includes a message notifying that a keyword relating to category information which is included in the selected category information sequence pattern and which is not included in the category information sequence is not included in the keyword sequence.

6. The information processing device according to claim 1 , wherein the one or more computer processors are configured to:
detect a keyword relating to an input item on an input screen from the keyword sequence, and set information depending on the detected keyword as a value of the input item.

7. The information processing device according to claim 1 , wherein the one or more computer processors are configured to:
determine whether the keyword included in the keyword sequence corresponds to a non-standard keyword based on a standard term database having standard keywords and the non-standard keyword associated therewith, and, in the case where the keyword corresponds to the non-standard keyword, replace the keyword in the keyword sequence with the standard keyword associated with the keyword.

8. The information processing device according to claim 1 , wherein the one or more computer processors are configured to:
convert a character string including one or more successive keywords detected in the keyword sequence into first notation indicating phonetic symbols of the character string,
specify, based on a database having a plurality of keywords and second notation indicating phonetic symbols of each of the plurality of keywords, one keyword among the plurality of keywords in the database based on correlation between the first notation and the second notation of each of the plurality of keywords, and
replace the character string in the keyword sequence with the specified one keyword or replace a portion corresponding to the character string in the text data with the specified one keyword.

9. The information processing device according to claim 8 , wherein the one or more computer processors are configured to:
specify a range of a value expected to be indicated by a first keyword in the keyword sequence based on a second keyword which has predetermined positional relationship with the first keyword, and,
when a value indicated by the first keyword does not fall within the range, detect a character string including one or more successive keywords including the first keyword from the keyword sequence.

10. The information processing device according to claim 9 ,
wherein the second keyword indicates a term of an item relating to measurement, and the range of the value expected to be indicated by the first keyword is a range of a measurement value which is expected to be obtained by the measurement.

11. An information processing device according to claim 1 , wherein
the position condition specifies a position after a predetermined number of characters after the keyword matching the term in the keyword sequence.

12. An information processing device according to claim 1 , wherein
the position condition specifies to extract a numeral value from within a predetermined number of characters after the keyword matching the term in the keyword sequence.

13. An information processing method performed by a computer, comprising:
generating a keyword sequence by performing morphological analysis on text data in natural language wherein the text data is obtained by performing voice recognition processing on data indicating speech content by a user wherein the speech content is relating to a patient or a person who is cared for;
acquiring, based on a database including keywords and category information associated therewith, category information corresponding to each keyword of the keyword sequence and generates a category information sequence;
selecting a category information sequence pattern from a plurality of category information sequence patterns according to correlation between the category information sequence and each category information sequence pattern;
comparing the selected category information sequence pattern with the category information sequence and generates presentation information according to a difference between the selected category information sequence pattern and the category information sequence;
outputting an input screen including a field for input of a value associated with a predetermined state of the patient or the person who is cared for, to a display device;
detecting a keyword matching a term expressing the predetermined state from the keyword sequence, and based on a template associating the term with a position condition, extracts a keyword located at a position satisfying the position condition for the detected keyword, from the keyword sequence; and
setting the extracted keyword in the field of the input screen as the value associated with the predetermined state.

14. A non-transitory computer readable medium having a computer program stored therein which, when the computer program is executed by a computer, causes the computer to perform processes comprising:
generating a keyword sequence by performing morphologica
