Abstract

A non-transitory computer-readable recording medium storing an estimation program that causes a processor included in a computer to execute a process. The process includes receiving a message of an estimation target of a forwarding destination, searching past messages for a message similar to the received message, estimating, when there is no similar message among the past massage, the forwarding destination of the message using a model of estimating the forwarding destination based on a keyword that is identified based on a word included in the received message, and outputting a forwarding destination of the searched similar message or the estimated forwarding destination.

First claim

What is claimed is:

1. A non-transitory computer-readable recording medium storing an estimation program that causes a processor included in a computer to execute a process, the process comprising:
receiving a message of an estimation target of a forwarding destination;
searching past messages for a similar message similar to the received message;
calculating similarity between the message and the similar message;
determining whether the similarity exceeds a threshold value;
outputting, when the similarity exceeds a threshold value, a forwarding destination of the similar message as the forwarding destination of the message;
estimating, when the similarity does not exceed the threshold value, the forwarding destination of the message using a model of estimating the forwarding destination based on a keyword that is identified based on a word included in the received message; and
outputting the forwarding destination which is estimated.

2. The non-transitory computer-readable recording medium according to claim 1 , wherein the estimating includes identifying the word as a keyword when the word is included in a keyword dictionary in which a plurality of keywords is set.

3. The non-transitory computer-readable recording medium according to claim 2 , wherein the estimating includes identifying the similar word as a keyword when the word is not included in the keyword dictionary and a similar word similar to the word is included in the keyword dictionary.

4. The non-transitory computer-readable recording medium according to claim 2 , wherein the plurality of keywords included in the keyword dictionary comprises a keyword used to create the model.

5. The non-transitory computer-readable recording medium according to claim 1 , wherein the outputting includes outputting information associated with the identified keyword in a case of outputting the estimated forwarding destination.

6. An estimation method comprising:
receiving a message of an estimation target of a forwarding destination;
searching past messages for a message similar to the received message;
calculating similarity between the message and the similar message;
determining whether the similarity exceeds a threshold value;
outputting, when the similarity exceeds a threshold value, a forwarding destination of the similar message as the forwarding destination of the message;
estimating, when the similarity does not exceed the threshold value, the forwarding destination of the message using a model of estimating the forwarding destination based on a keyword that is identified based on a word included in the received message; and
outputting the forwarding destination which is estimated.

7. The estimation method according to claim 6 , wherein the estimating includes identifying the word as a keyword when the word is included in a keyword dictionary in which a plurality of keywords is set.

8. The estimation method according to claim 7 , wherein the estimating includes identifying the similar word as a keyword when the word is not included in the keyword dictionary and a similar word similar to the word is included in the keyword dictionary.

9. The estimation method according to claim 7 , wherein the plurality of keywords included in the keyword dictionary comprises a keyword used to create the model.

10. The estimation method according to claim 6 , wherein the outputting includes outputting information associated with the identified keyword in a case of outputting the estimated forwarding destination.

11. An information processing device comprising:
a receiver configured to receive a message of an estimation target of a forwarding destination; and
a processor configured to:
search past messages for a message similar to the received message,
calculate similarity between the message and the similar message;
determine whether the similarity exceeds a threshold value;
output, when the similarity exceeds a threshold value, a forwarding destination of the similar message as the forwarding destination of the message;
estimate, when the similarity does not exceed the threshold value, the forwarding destination of the message using a model of estimating the forwarding destination based on a keyword that is identified based on a word included in the received message, and
output the forwarding destination which is estimated.

12. The information processing device according to claim 11 , wherein the processor identifies the word as a keyword when the word is included in a keyword dictionary in which a plurality of keywords is set.

13. The information processing device according to claim 12 , wherein the processor identifies the similar word as a keyword when the word is not included in the keyword dictionary and a similar word similar to the word is included in the keyword dictionary.

14. The information processing device according to claim 12 , wherein the plurality of keywords included in the keyword dictionary comprises a keyword used to create the model.

15. The information processing device according to claim 11 , wherein the processor outputs information associated with the identified keyword in a case of outputting the estimated forwarding destination.
