Abstract

A communication terminal having an email message sending-and-receiving function includes an email-message history information storing unit configured to store email-message information of at least a sent email message as email-message history information, an intended-to-be-sent email message storing unit configured to store email-message information of an intended-to-be-sent email message, the intended-to-be-sent email message being an email message which is going to be sent, as intended-to-be-sent email message information, a destination-address right/wrong determining unit configured to determine whether a destination address of the intended-to-be-sent email message is right or wrong by comparing the email-message history information with the intended-to-be-sent email message information, and a unit configured to send, if the destination address is determined to be wrong, a notification of the wrong destination address to a user and to request the user to check the destination address.

Claims

1. A communication terminal having an email message sending-and-receiving function, the communication terminal comprising:

email-message history information storing means for storing email-message information of at least a sent email message as email-message history information;

intended-to-be-sent email message storing means for storing email-message information of an intended-to-be-sent email message, the intended-to-be-sent email message being an email message which is going to be sent, as intended-to-be-sent email message information;

destination-address right/wrong determining means for determining whether a destination address of the intended-to-be-sent email message is right or wrong by comparing the email-message history information with the intended-to-be-sent email message information; and

means for sending, if the destination address is determined to be wrong, a notification of the wrong destination address to a user and requesting the user to check the destination address.

2. The communication terminal according to claim 1, further comprising keyword extracting means for extracting keywords per target address from the email-message history information and extracting keywords from the intended-to-be-sent email message,

wherein the destination-address right/wrong determining means determines whether the destination address of the intended-to-be-sent email message is right or wrong by comparing the keywords extracted from the intended-to-be-sent email message information with those extracted from the email-message history information.

3. The communication terminal according to claim 2, wherein the keyword extracting means adds weight information to each of the keywords per target address extracted from the intended-to-be-sent email message information on the basis of a frequency of appearance of the keyword per message when the keywords per address are extracted, and the destination-address right/wrong determining means uses the weight information at the time of the comparison.

4. The communication terminal according to claim 2 or 3, wherein the destination-address right/wrong determining means obtains a degree of email-message correlation between the intended-to-be-sent email message and at least a sent email message sent to a target address by the comparison, and determines whether the destination address of the intended-to-be-sent email message is right or wrong on the basis of the degree of email-message correlation.

5. The communication terminal according to any one of claims 2 to 4, wherein whether the destination address of the intended-to-be-sent email message is determined to be right or wrong by comparing the email-message history information of a target address which is the same as the destination address of the intended-to-be-sent email message with the intended-to-be-sent email message information.

6. The communication terminal according to any one of claims 2 to 4, wherein whether the destination address of the intended-to-be-sent email message is determined to be right or wrong by comparing the email-message history information of a plurality of target addresses with the intended-to-be-sent email message information regardless of whether or not each of the target addresses is the same as the destination address of the intended-to-be-sent email message.

7. The communication terminal according to claim 4, wherein if a keyword implying a person'"'"'s name is included in the first several lines of a message body of the intended-to-be-sent email message and if the keyword exists in the keywords corresponding to the target address, the degree of email-message correlation for the target address is increased by a predetermined amount or a predetermined ratio.

8. The communication terminal according to claim 4, further comprising means for providing, if another target address has a higher degree of email-message correlation than the target address which is the same as the destination address, the target address having the higher degree of email-message correlation as a destination candidate to a user.

9. A destination-address right/wrong determining method used in a communication terminal having an email message sending-and-receiving function, the method comprising the steps of:

storing email-message information of at least a sent email message as email-message history information;

storing email-message information of an intended-to-be-sent email message, the intended-to-be-sent email message being an email message which is going to be sent, as intended-to-be-sent email message information;

determining whether a destination address of the intended-to-be-sent email message is right or wrong by comparing the email-message history information with the intended-to-be-sent email message information; and

sending, if the destination address is determined to be wrong, a notification of the wrong destination address to a user and requesting the user to check the destination address.

10. An address right/wrong determining program performed by a computer in a communication terminal having an email message sending-and-receiving function, the program allowing the computer to perform the steps of:

storing email-message information of at least a sent email message as email-message history information;

storing email-message information of an intended-to-be-sent email message, the intended-to-be-sent email message being an email message which is going to be sent, as intended-to-be-sent email message information;

determining whether a destination address of the intended-to-be-sent email message is right or wrong by comparing the email-message history information with the intended-to-be-sent email message information; and

sending, if the destination address is determined to be wrong, a notification of the wrong destination address to a user and requesting the user to check the destination address.

11. A communication terminal having an email message sending-and-receiving function, the communication terminal comprising:

an email-message history information storing unit configured to store email-message information of at least a sent email message as email-message history information;

an intended-to-be-sent email message storing unit configured to store email-message information of an intended-to-be-sent email message, the intended-to-be-sent email message being an email message which is going to be sent, as intended-to-be-sent email message information;

a destination-address right/wrong determining unit configured to determine whether a destination address of the intended-to-be-sent email message is right or wrong by comparing the email-message history information with the intended-to-be-sent email message information; and

a unit configured to send, if the destination address is determined to be wrong, a notification of the wrong destination address to a user and to request the user to check the destination address.
