Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for a user to reject unsolicited message reception in a message exchange type communication system such as IM (Instant Message).

[0002]

2. Description of the Related Art In recent years, IM (Instant Message)
In such a message exchange type communication system, there are an increasing number of cases in which a message is suddenly sent from a stranger, or users who have no friends in the real world become friends through a network and communicate with each other. In such a message exchange system, the number of cases in which an unpleasant message is received from the other party also increases, and it is considered that an unwanted message rejection method for preventing it is important. For example, a situation in which solicitation messages for a large number of products and messages including a large number of sexual expressions fly around is a common occurrence in an environment in which an unspecified number of people communicate.

As a method of rejecting such a nuisance message, 1. 1. A method for disallowing all messages from users registered in the reception disallowed list. 2. A method of disallowing the reception of messages from all users other than the users registered in the reception permission list. How to manage the annoyance level for each user. In this method, if the message recipient determines that the message sender is a nuisance, it can notify the server operating the system as a nuisance, and depending on the number notified, each user can be notified. It is considered that the annoyance level of the user is determined, and the annoyance level is displayed on the receiving side every time the user sends a message, so that the annoyance level can be used as a criterion for rejecting the message of the user.

[0004]

In the conventional nuisance message rejection method, only the method of rejecting a message according to the other party is specified. Therefore, each method described in the related art has the following problems. 1. For disabling all message reception from users who are registered in the blocked transmission list, register the sender in the blocked list after the user determines that the sender is annoying. There is a possibility that the user will receive an unpleasant message once and display it, so it cannot be said to be a complete rejection method for unwanted messages. 2. In the method of disallowing the reception of messages from all users other than the users registered in the reception allowance list, all favorable messages from users who are not registered in the reception allowance list other than unwanted users are rejected. As a result, new communication opportunities through the network will be lost, which is not an effective method in this sense. 3. In the method of managing the degree of annoyance for each user, it is possible that the user with accumulated annoyance may take the action of acquiring a new user account, and as a result, until the annoyance of the sender is given. In the meantime, the user is likely to receive an offensive message.

As described above, since the above 1, 2 and 3 reject the message according to the other party, the user cannot perform the action of rejecting according to the content of the message.

According to the present invention, in a method of rejecting a junk message on a message exchange system, a user rejects a message according to a phrase included in a received message, instead of rejecting the message according to a sender. The aim is to provide a system of choice.

[0007]

The system according to the present invention employs the following means in order to solve the above problems. First, when the user's terminal receives the message, it performs word matching between the phrase in the junk phrase dictionary set in the user terminal and the phrase in the message, and as a result, if the junk phrase is included. Is
By displaying a dialog to the user and giving the user the option of displaying the content of the message or rejecting it, it becomes possible for the user to reject the unwanted message. Therefore, it is possible to realize a system in which the user can select rejection of the message according to the phrase included in the received message.

By using this method, the user can reject the reception of the message by the nuisance phrase included in the message rather than by the other party. Points 1 and 2
It is possible to provide users with a method of rejecting unsolicited messages that solves each of the problems, such as the possibility of receiving an unpleasant message once, and the chance of losing the communication of the user of problem 2. become.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a diagram for explaining the unwanted message rejection method according to the present embodiment.

In the figure, 10 is a message receiving terminal having this system, and 20 is a message transmitting terminal. Reference numeral 11 is a junk word dictionary in which the user can select and use the junk words entered by the user and the genres of the junk words prepared by the system (solicitation, politics, violence, sexual expression, etc.). .

When a message arrives at the message receiving unit on the receiving terminal, the message analyzing unit 12
As shown in (1) in the figure, word matching is performed between the word / phrase included in the message and the word / phrase registered in the annoying word / phrase dictionary to detect annoying word / phrase. For example, it is assumed that the user has selected a phrase related to solicitation of a product as a nuisance phrase.
In the nuisance phrase dictionary, it is considered that there are “sale”, “large special price”, “limited time period”, and the like as terms relating to such solicitation. At this time, it is assumed that the message sent from the transmitting terminal 10 includes the above-mentioned phrase "a personal computer is on sale now !!". in this case,
Since the word "sales" is included in the message, it is determined that the received message contains junk phrases.

When the message analysis unit 12 detects a nuisance phrase in the message received by the message receiving unit 13 ((2) in the figure), the nuisance phrase detection notifying unit 14 notifies the user of the nuisance phrase in the received message. Notify that is included. In addition, as shown in (3) in the figure,
The nuisance phrase detection / notification unit 14 has a message display selection unit 15 for opening the message or rejecting and discarding the message. Here, when "Discard message" is selected, the content of the message is discarded without being displayed to the user. On the other hand, when "Do not discard" is selected, the content of the message is displayed to the user through the message display unit 16 ((4) in the figure).

Next, the function of the message analysis unit will be described with reference to FIG. FIG. 2 is an explanatory diagram of the message analysis unit. In the figure, 10 is a message receiving terminal having this system, and 20 is a message transmitting terminal.

The message analysis unit 12 prepares a list 12a similar to the application list as shown in FIG. 2, and can decide whether or not to apply the unwanted message rejection method according to the message sender. For example, in the figure, it is applied to sender A, sender C, known (a group of users who have exchanged a message once), and unknown (an unknown sender who has never exchanged a message). However, it does not apply to sender B and receives all messages unconditionally. This system can be applied not only to the sender but also to each group such as the group F (both not shown) to which the sender D and the sender E belong. When a message is received from an unknown sender, this sender is registered in the list of already-sent senders, and the present system is applied from the next message as known.

Further, the unwanted message rejection method can set the applicable range for the message. In the example of FIG. 2, since the first application is for the sender A and the known sender, only the first message sent from the sender A is sent when the user terminal is in operation. Apply the system. The first message sent from the sender A refers to the message sent from the sender A for the first time after login when the user is logged in to the service and is using the service. That is, the system is applied to the sender A's first message each time the user logs in to the service. On the other hand, for sender B and unknown sender, this system is applied to all messages.

Next, the nuisance phrase dictionary 11 will be described with reference to FIG. FIG. 3 is an explanatory diagram of the junk word dictionary.
In the figure, 11 is a junk phrase dictionary, and 30 is a server providing this system. The nuisance phrase dictionary 11 allows the user to specify the nuisance phrase as shown by (11) in the figure.
Further, the genre of the junk phrase prepared by the system in advance can be designated as shown in (12) in the figure. In the example shown in the figure, the message rejection method operates on a message containing a solicitation and sexual expression. In this annoying genre, annoying words and phrases suitable for each genre are managed, and the contents of the annoying words and phrases are communicated with the server 30 to communicate and use the annoying words and phrases as shown in (13) in the figure. Will always be able to provide the latest phrase to the person.

In the above embodiment, when the received message contains a junk phrase, the user is allowed to select whether or not to display the received message. However, the junk phrase may be deleted from the received message. Alternatively, it may be displayed after being replaced with another character. Such a case will be described with reference to FIG. FIG. 4 is a diagram for explaining the processing of the received message.

In the figure, 41 is the content of the message received by the user terminal. Reference numeral 42 is an example of a message display selection display window displayed as a result of analyzing the message in the message analysis unit 12. Furthermore, 43 is a display example when partial display is selected in the message display selection display window.

As shown in FIG. 4, the message 41 is a message containing the words "sale" and "purchase" for soliciting products. When such a message is received, the message analysis unit 12 determines that the nuisance word is not included. 2 words, Judge that the content of the nuisance is solicitation of goods. In addition, at this time, when the partial display such as displaying by excluding only the nuisance phrase is selected in the selection unit 42, “sale in progress” and “purchase” are replaced with other characters as in the message 43, or erased. Will be displayed. In addition, a flexible partial display can be performed by selecting a line including a nuisance phrase or excluding only a paragraph. In this example, it may seem like there isn't much meaning to display the partial display as being on sale, but there is an advantage in that it can erase messages that cover the eyes such as sexual expressions for women. The purpose is to respond well.

[0020]

As described above, according to the present invention, a nuisance message can be rejected not according to the other party but according to the phrase included in the message. Users can choose to reject the message.
