Data labeling work support apparatus, data labeling work support method, and storage medium

A data labeling work support method comprising:

• acquiring training data including a plurality of data pieces;
• acquiring a plurality of first labels manually assigned to the data pieces of the training data;
• extracting features of the data pieces of the training data by using a first unsupervised learning method without labels;
• grouping the data pieces of the training data based on a similarity or a distance of the features by using a second unsupervised learning method;
• assigning a plurality of second labels to the grouped data pieces of the training data by using the second unsupervised learning method;
• calculating, for each of the data pieces, a degree of matching between the first label assigned to the data piece and the second label assigned to the data piece;
• displaying, on a screen of a display device, a plurality of plot points representing the training data using the features, each plot point corresponding to one data piece;
• and
• highlighting a plot point representing a data piece of the training data corresponding to a combination of the first label and the second label having a low degree of matching.

A non-transitory computer readable storage medium for storing a data labeling work support program for causing a computer to execute processing comprising:

• acquiring training data including a plurality of data pieces;
• acquiring a plurality of first labels manually assigned to the data pieces of the training data;
• extracting a features of the data pieces of the training data by using a first unsupervised learning method without labels;
• grouping the data pieces of the training data based on a similarity or a distance of the features by using a second unsupervised learning method;
• assigning a plurality of second labels to the grouped data pieces of the training data by using the second unsupervised learning method;
• calculating, for each of the data pieces, a degree of matching between the first label assigned to the data piece and the second label assigned to the data piece;
• displaying, on a screen of a display device, a plurality of plot points representing the training data using the features, each plot point corresponding to one data piece;
• and
• highlighting a plot point representing a data piece of the training data corresponding to a combination of the first label and the second label having a low degree of matching.
