Learning device, management sheet creation support device, non-transitory computer-readable storage medium, learning method, and management sheet creation support method

A management sheet creation support device, comprising:

• storage to store a correspondence relationship model for a past case sheet created in a past as a management sheet and a plurality of documents, the management sheet including a plurality of rows, each of the plurality of rows including at least operation process information indicative of one operation process included in a plurality of operation processes and a risk sentence indicative of information about a risk in the one operation process, the correspondence relationship model being generated by learning a correspondence relationship between the operation process information and the risk sentence through use of correspondence relationship training data, which is training data including a positive example and a negative example, the positive example being a combination of the operation process information included in one of the plurality of rows and the risk sentence included in the one row, the negative example being a combination of the operation process information included in the one row and a risk sentence included in a row different from the one row;
• a processor to execute a program;
• and
• a memory to store the program which, when executed by the processor, performs processes of,
• acquiring search operation process information, which is operation process information for search;
• generating a plurality of pieces of search sequence data by adding each of a plurality of sentences included in the plurality of documents to the search operation process information, sum a plurality of scores obtained by inputting the plurality of pieces of search sequence data into the correspondence relationship model, for each of the plurality of documents, each including the plurality of sentences, and then specify a document with a highest summed score as reference information;
• and
• generating a screen image for displaying the reference information.

A non-transitory computer-readable storage medium storing a program that causes a computer to execute processing comprising:

• storing a past case sheet created in a past as a management sheet, the management sheet including a plurality of rows, each of the plurality of rows including at least operation process information indicative of one operation process included in a plurality of operation processes and a risk sentence indicative of information about a risk in the one operation process;
• generating correspondence relationship training data, which is training data including a positive example and a negative example, the positive example being a combination of the operation process information included in one of the plurality of rows in the past case sheet and the risk sentence included in the one row, the negative example being a combination of the operation process information included in the one row and the risk sentence included in a row different from the one row;
• and
• generating a correspondence relationship model by learning a correspondence relationship between the operation process information and the risk sentence through use of the correspondence relationship training data.
