FIG. 15 is a flowchart showing an example of the flow of emotion analysis processing by the second mobile phone 20 according to the present embodiment.

  In step S31, the second control unit 26 (second emotion analysis unit 264) performs analysis from the beginning of the mail document.

  In step S <b> 32, the second control unit 26 (second emotion analysis unit 264) determines whether or not the mail title includes a character string corresponding to the reply or a character string corresponding to the transfer. The second control unit 26 (second emotion analysis unit 264) moves the process to step S33 when this determination is YES, and moves the process to step S38 when this determination is NO. If this determination is NO, that is, if the character string corresponding to the reply or the character string corresponding to the transfer is not included, it is unlikely that a quotation mark is included, so the processing from step S33 to step S37 is performed. Will be omitted.

  Since the process from step S33 to step S38 is the same as the process of the 1st control part 16 from step S22 to step S27, description is abbreviate | omitted.

  In step S39, the second control unit 26 (second notification control unit 265) displays the emotion analyzed in step S38 on the second display unit 21, thereby creating the user who sent the mail, that is, the mail. Informs the user's feelings.

As described above, the first mobile phone 10 according to the present embodiment uses the first emotion analysis unit 164 to extract the character string stored in the first emotion table 151 of the first storage unit 15 from the mail document. The emotion analysis of the mail document is performed based on the emotion associated with the extracted character string, and the emotion of the analyzed mail document is notified by the first emotion analysis unit 164.
Therefore, the user on the sending side can grasp what kind of feeling the mail sent by the user shows.

In addition, when the mail document is updated, the first emotion analysis unit 164 analyzes the emotion of the updated mail document, and the first notification control unit 165 notifies the updated mail emotion.
Therefore, the first mobile phone 10 can notify the user of the latest analysis result in response to the addition or change of the character string to the character string included in the mail.

In addition, when the mail document includes a quotation mark, the first emotion analysis unit 164 does not perform emotion analysis on the character string after the quotation mark.
Therefore, the first mobile phone 10 excludes the character string after the quotation mark, which is a character string created by another person, as a character string that is not appropriate for the user's emotion analysis from the emotion object of the mail document, Emotion analysis can be performed.

In addition, when the mail document includes a quotation mark, the first emotion analysis unit 164 performs an emotion analysis on a character string between the quotation mark and a new line character that first appears after the quotation mark. Do not do.
Therefore, the first mobile phone 10 is a character string created by another person from the quotation mark to the first newline character that appears after the quotation mark, and is not suitable for analyzing the emotion of the user. As a character string, it can be excluded from the emotion object of the mail document and emotion analysis can be performed.

In addition, the first notification control unit 165 notifies the emotion of the mail document between the time when the first operation unit 12 performs the mail transmission and the time when the transmission receiving unit 163 transmits the mail.
Therefore, the first mobile phone 10 notifies the user of the emotion of the mail document before the user of the first mobile phone 10 transmits the mail, so that the user is estimated from the mail document before transmitting the mail. Can understand the emotions.

In addition, when one of the prediction conversion candidates output by the prediction conversion unit 162 is selected, the first emotion analysis unit 164 analyzes the emotion of the mail document including the selected prediction conversion candidate, and performs the first notification control. When the emotion of the mail document is different from the emotion of the mail document before the prediction conversion candidate is added, the unit 165 reports the emotion of the mail document.
Therefore, the first mobile phone 10 can notify the emotion of the mail document in consideration of the character string of the predictive conversion candidate that the user intends to input from now on.

The first emotion analysis unit 164 analyzes the emotion of the output at least one prediction conversion candidate, and the first notification control unit 165 applies the emotion of each prediction conversion candidate analyzed by the first emotion analysis unit 164. Predictive conversion candidates are displayed in a corresponding manner.
Therefore, since the first mobile phone 10 can cause the user to confirm the emotion corresponding to the prediction conversion candidate, the user can select an appropriate prediction conversion candidate.

  In addition, the first notification control unit 165 causes the first display unit 11 to execute display indicating the emotion of the mail document. That is, when the display based on the emotion of the mail document is an icon, the first mobile phone 10 can simply express the emotion of the mail document.

In addition, when the second emotion analysis unit 264 receives a mail transmitted from the first mobile phone 10 by the second communication unit 24 and the mail document includes quotation marks, the second emotion analysis unit 264 performs emotion analysis on the mail document. Not performed.
Therefore, the second mobile phone 20 can omit the emotion analysis in the case of a mail that cannot estimate the sender's emotion, such as a forward mail or a reply mail.

  As mentioned above, although embodiment of this invention was described, this invention is not restricted to embodiment mentioned above. The effects described in the embodiments of the present invention are only the most preferable effects resulting from the present invention, and the effects of the present invention are limited to those described in the embodiments of the present invention. is not.
