Abstract

A novel content classification method is provided. A content classification method using machine learning for a learning model and a classifier fabrication method are provided. In Step 1, a data set containing a plurality of contents is acquired. Learning labels are attached to m contents, and the learning labels are not attached to the remaining contents. In Step 2, a first learning model is created by machine learning using the m contents. In Step 3, judgment labels are attached to the plurality of contents using the first learning model and are displayed on a GUI. In Step 4, new learning labels are attached to k contents in the plurality of contents. In Step 5, a second learning model is created by the machine learning using the k contents. In Step 6, judgment labels are attached to the plurality of contents using the second learning model and are displayed on the GUI.

Claims (46)

1. A content classification method of a computer device, comprising the steps of:

acquiring a data set comprising a plurality of contents including m contents to which a learning label is attached and n contents to which the learning label is not attached;

creating a first learning model by machine learning using the m contents;

attaching a judgment label to the plurality of contents using the first learning model and displaying the judgment label in a graphical user interface;

attaching a learning label to q contents in the n contents;

creating a second learning model by the machine learning using the (q+m) contents to which the learning label is attached;

attaching a judgment label to the plurality of contents using the second learning model and displaying the judgment label in the graphical user interface;

calculating a first score for estimating the judgment label;

promoting label attachment when the first score of a record is greater than or equal to 0.5 and less than 0.65; and

changing, based at least in part on the first score, a display order of the judgement label in the graphical user interface,

wherein m, n, and q each represent a natural number.

2. The content classification method according to claim 1 , wherein the plurality of contents include text.

3. The content classification method according to claim 1 , further comprising a step of clustering using unsupervised learning on the data set including the plurality of contents.

4. The content classification method according to claim 1 , wherein the plurality of contents include text in a patent document.

5. The content classification method according to claim 1 , wherein the judgment label and the learning label are two classes.

6. A content classification method of a computer device, comprising the steps of:

acquiring a data set comprising a plurality of contents including m contents to which a learning label is attached and n contents to which the learning label is not attached;

creating a first learning model by machine learning using the m contents;

attaching a judgment label to the plurality of contents using the first learning model and displaying the judgment label in a graphical user interface;

attaching a learning label to k contents in the plurality of contents;

creating a second learning model by the machine learning using the k contents to which the learning label is attached;

attaching a judgment label to the plurality of contents using the second learning model and displaying the judgment label in the graphical user interface;

calculating a first score for estimating the judgment label;

promoting label attachment when the first score of a record is greater than or equal to 0.5 and less than 0.65; and

changing, based at least in part on the first score, a display order of the judgement label in the graphical user interface,

wherein m and k each represent a natural number.

7. The content classification method according to claim 6 , wherein the plurality of contents include text.

8. The content classification method according to claim 6 , further comprising a step of clustering using unsupervised learning on the data set including the plurality of contents.

9. The content classification method according to claim 6 , wherein the plurality of contents include text in a patent document.

10. The content classification method according to claim 6 , wherein the judgment label and the learning label are two classes.

11. A content classification method of a computer device, comprising the steps of:

acquiring a data set comprising a plurality of contents including m contents to which a learning label is attached and n contents to which the learning label is not attached;

calculating a first score for estimating a judgment label of the plurality of contents using the m contents;

displaying a list of labels determined based on the first score and attached to the plurality of contents in a graphical user interface;

attaching a learning label to k contents in the plurality of contents included in the list;

creating a learning model by machine learning using the k contents to which the learning label is attached;

calculating a second score for estimating the judgment label of the plurality of contents;

displaying the list of the judgment labels determined based on the second score and attached to the plurality of contents in the graphical user interface;

promoting label attachment when the first score of a record is greater than or equal to 0.5 and less than 0.65; and

changing, based at least in part on the first score, a display order of the judgement labels in the graphical user interface,

wherein m and k each represent a natural number.

12. The content classification method according to claim 11 , further comprising a step of specifying a specific numerical range in the first score and attaching a learning label to the corresponding content.

13. The content classification method according to claim 11 , wherein the plurality of contents include text.

14. The content classification method according to claim 11 , further comprising a step of clustering using unsupervised learning on the data set including the plurality of contents.

15. The content classification method according to claim 11 , wherein the plurality of contents include text in a patent document.

16. The content classification method according to claim 11 , wherein the judgment label and the learning label are two classes.
