Description

Method for classification of e-mail}

The present invention relates to an email classification method, and more particularly, to a method for classifying a news mail using information included in a header and a body of a received email.

Email or e-mail has deepened our lives with the development of the Internet. Personal or business letters can be delivered to the other party quickly and accurately by e-mail, which facilitates easy processing, and various bills, bills, etc. can also be delivered to the other party via e-mail, thereby preventing unnecessary waste of paper.

However, with the development of e-mail, problems have arisen due to spam mail or junk mail. In other words, spam mail or junk mail is an email sent by a sender to a recipient who has nothing to do with it, and most of the domestic email users have received such spam mails and are suffering a burden.

In order to solve the problem caused by spam mails, many technologies have been developed to automatically block spam mails. In other words, spam mail is a mail sent from one sender to a plurality of recipients, and the mail is classified as spam mail and the mail server (mail server) automatically blocks it. In addition, the mail server stores the information about the email classified as spam mail from the user and automatically blocks when the spam mail is received again.

However, in addition to spam mails, mails sent from one sender to multiple recipients may include news mails (for example, emails that are regularly sent to customers by a news provider) and general group mails. Blocking technology has a problem that it is difficult to distinguish between such news mail and general group mail. In addition, if any user has classified any newsletter as spam mail, the mail server may classify the newsletter as spam mail and other users who subscribe to it may suffer damage.

On the other hand, even if the news mail is not classified as a spam mail, if mixed with the general e-mail, the user has a problem that it is difficult to retrieve the news mail again after a period of time. Of course, there are e-mail programs or systems that can store received e-mails in separate folders according to the user's settings, but it is difficult for users to make these settings and it is difficult to activate them because many users do not know how to set them. This still remains.

In order to solve the above problems, the present invention is to provide an email classification method that can prevent the news mail is classified as spam mail.

In addition, the present invention is to provide an email classification method that can automatically classify news mail with other general email.

According to an aspect of the present invention, an email classification method performed in a receiver terminal or an email server, the method comprising: receiving an email from a sender terminal; Analyzing body information of the email, if previously stored in a storage space provided with the sender information of the email; And determining the email as a news mail when the plurality of link information included in the body information corresponds to the same email server.

The determining of the e-mail as the news mail may include determining the e-mail as the news mail if at least one of the message ID information and the return path information of the e-mail is previously stored in the storage space.

The determining of the e-mail as a news mail may further include determining the e-mail as the news mail if a predetermined keyword is included in the subject information of the e-mail.

The determining of the e-mail as a news mail may further include determining the e-mail as the news mail if the sender name of the e-mail is included in at least one of the title information and the body information.

The email classification method may further include: transmitting the email to a connected central server if the email classification method is not previously stored in a storage space including sender information of the email; And when the news information is received from the central server, determining the e-mail as a news mail.

In addition, the central server may transmit the news information when one or more of the received email, message ID information, and return path information have received the same email or are received within a preset time.

In addition, the central server may transmit the news information when another e-mail including a portion other than a pre-set keyword is received in the body information of the e-mail received or received within a preset time.

The email classification method may further include storing the email corresponding to the news information in the storage space.

According to another embodiment of the present invention, an email classification method performed in a central server, the method comprising: receiving an outgoing email from a sender terminal; And comparing the at least one of the header information and the body information of the outgoing e-mail with another received e-mail according to a preset method to determine whether the outgoing e-mail is a news mail.

Here, the determining whether the outgoing email is a news mail may include classifying the outgoing email as the newsmail when one or more of the outgoing email, the message ID information, and the return path information have been received or received within a preset time. It may further comprise a step.

In addition, the determining whether the outgoing email is a news mail may include determining that the outgoing email is the newsmail when another e-mail including or including a portion of the body information of the outgoing email including a predetermined keyword is received or received. The method may further include classifying.

In addition, the e-mail classification method may further include analyzing the e-mail according to a preset method and determining whether the e-mail is a spam mail when it is determined that the e-mail is not the news mail.

In addition, the email classification method may further include determining that the email is a normal mail when it is determined that the email is not the spam mail.

According to still another embodiment of the present invention, there is provided a computer-readable recording medium having recorded thereon a program for executing an email classification method according to any one of claims 1 to 13 on a computer.

The email classification method according to the present invention can prevent the news mail from being classified as spam mail.

In addition, the email classification method according to the present invention can automatically classify news mails with other general emails, so that users can more easily browse the news mails.

Referring to FIG. 1, an email classification system 100 according to an embodiment of the present invention includes a central server 110, n email servers 120-n (where n is a natural number), and m user terminals 130. -m), where m is a natural number. In addition, the central server 110, n email servers 120-n, and m user terminals 130-m are wirelessly or wiredly connected through the network 140. Here, if the network 140 is a network that connects each component of the e-mail classification system 100 to transmit and receive signals or data therebetween, the network 140 may be applied regardless of its type. For example, the network 140 may be one or more of a network such as the Internet, an intranet, or a mobile network. Hereinafter, the operation of each component of the e-mail classification system 100 will be described in detail.

The central server 110 classifies e-mails received from the e-mail server 120-n and / or the user terminal 130-m according to a preset method. For example, the central server 110 may determine whether an e-mail received from the e-mail server 120-n is news mail, spam mail, or personal general mail containing the contents of the news. Classify according to the preset method.

The e-mail server 120-n receives an e-mail from the user terminal 130-p (hereinafter, referred to as a sender terminal) that sends an e-mail (where p is a natural number of m or less). In addition, the email server 120-n transmits the received email to the user terminal 130-k (hereinafter, referred to as a receiver terminal) to receive the email (where k is a terminal of m or less). In particular, the e-mail server 120-n may classify the received e-mail according to a preset method, or may transmit the received e-mail to the central server 110 to classify the e-mail. That is, if the e-mail server 120-n is stored in a storage space provided with information on the received e-mail, the e-mail server 120-n may classify the e-mail type according to a preset method. ) To be classified (by the central server 110).

The user terminal 130-m, in particular the sender terminal 130-p, transmits an e-mail generated according to a user's operation to the e-mail server 120-n to transmit to the receiver terminal 130-k. In addition, the receiver terminal 130-k displays the received e-mail so that the user can visually or audibly recognize the e-mail. In particular, the receiver terminal 130-k may classify the received email into news mail, spam mail or general mail according to a preset method, and transmit the received email to the central server 110 in order to classify the email. have. That is, if the receiver terminal 130-k is stored in a storage space provided with information on the received email, the type of the email may be classified according to a preset method. If not, the receiver terminal 130-k may divide the email into a central server 110. ) To be classified (by the central server 110).

As described above, the e-mail server 120-n or the receiver terminal 130-k classifies the received e-mail according to a preset method, or classifies the received e-mail so that the received e-mail can be classified. Can be sent to. Hereinafter, the e-mail structure will be briefly described with reference to FIG. 2, and then the e-mail received by the central server 110, the e-mail server 120-n, and / or the receiver terminal 130-k is classified according to a preset method. How to do this is explained in detail.

2 is a diagram of the structure of an email.

Referring to FIG. 2, the email may include header information 210, body information 220, and closing information 230. Here, the header information 210 includes information on the e-mail itself, the body information 220 includes information on the content for the sender to notify the recipient through the e-mail, the closing information 230 The conclusion of the caller's choice or personal information of the caller may be included.

That is, the header information 210 may include information on the sender (hereinafter, referred to as caller information). The sender information may include a name or name of the sender, an e-mail address, and a caller terminal. Information about the IP of p) may be included. In addition, the header information 210 may include information on the recipient (hereinafter referred to as recipient information), and the recipient information includes information on the name or name of the recipient, an e-mail address, an IP of the receiver terminal 130-k, and the like. May be included.

In addition, the header information 210 may include message ID information (Message-ID), the message ID information is an external mail server or email received from the email server 120-n connected to the sender terminal (130-p) The serial number may be transmitted to the receiver terminal 130-k and included in the header information 210 according to a preset method.

In addition, the header information 210 may include return path information (Received), and the return path information is transmitted to any e-mail server 120-k through an e-mail server 120-p, and any recipient. It may be information about whether or not transmitted to.

In addition, the header information 210 may include subject information. The subject information may be information about a subject of the e-mail input to the sender terminal 130-p by the sender's selection.

In addition, the header information 210 includes other information (X-mailer) on the program (program or software) that generated the email, information on the priority of the email (X-priority) set by the sender's selection, and the like. It may be further included.

Meanwhile, as described above, the body information 220 included in the e-mail includes contents that the sender wants to deliver to the receiver through the e-mail, and includes text, image, and movie. One or more hyperlinks may be set in the text, image, video, etc. according to the sender's selection, so that the receiver can more easily browse the homepage corresponding to the body information. Therefore, the information on the homepage set to be connected according to the hyperlink is called link information.

In addition, the closing information 230 may include information about the sender's special sign (Sign), typically, the closing information 230 includes the caller's name, affiliation, contact information (phone number, email address, etc.). . In the following description, it is assumed that the conclusion information 230 is information included in the body information 220.

In the above, the structure of the e-mail has been briefly described. Hereinafter, e-mail classification methods according to an embodiment of the present invention will be described in detail with reference to FIGS. 3 and 4.

3 is a flowchart illustrating an email classification method according to an embodiment of the present invention.

Each step to be described below may be a step performed by the e-mail server 120-n described with reference to FIG. 1, and may be an e-mail server 120-p or a receiver terminal 130-connected to the sender terminal 130-p. k) may be performed in an email server 120-k connected to the server. In addition, each of the steps to be described below may be steps performed in the receiver terminal 130-k described with reference to FIG. 1. However, for convenience of understanding and explanation, it will be described collectively as being performed in the email server 120-n. Therefore, the subject performing the steps described below can be omitted.

In step S300, when the e-mail transmitted from the sender terminal 130-p is received, the sender information included in the e-mail is compared with the pre-stored news mail information (step S310). That is, the e-mail server 120-n may include a storage space. Since the news mail information may be pre-stored in the storage space, the e-mail server 120-n stores the same news mail information as the sender information. Can be determined. Here, the news mail information may be information about a name or name of the sender who sends the news mail, an e-mail address, an IP, and the like. Accordingly, the e-mail server 120-n may compare the sender information included in the e-mail with the previously stored news mail information to determine whether the received e-mail is an e-mail transmitted by the sender who transmits the news mail. For example, the e-mail server 120-n may determine whether the e-mail server 120-n is stored in a storage space provided with at least one of a sender's name or name, an e-mail address, and an IP of the received e-mail.

In step S315, if the sender information included in the e-mail is stored in the storage space provided, the body information 220 of the e-mail is analyzed and a plurality of link information included in the body information 220 is the same server. It is determined whether or not to correspond to (step S320 to step S325). That is, if the sender information included in the received e-mail is stored in the storage space provided with the e-mail, the e-mail server 120-n analyzes the body information 220 because the e-mail may be a news mail. In addition, the email server 120-n may determine whether a plurality of hiberlinks are included in the body information 220 of the received email, and link information corresponding to the plurality of hyperlinks corresponds to the same server. (I.e., it may be determined whether a plurality of hyperlinks are all set to connect to the same server or homepage).

In the case of news mail, the homepage address where the news is posted is hyperlinked to the text information 220 so that the user can access the homepage of the news provider (ie, the sender) and subscribe in more detail. At the end of 220, the news provider's main homepage address is typically hyperlinked. That is, a news mail generally includes a plurality of hyperlinks included in the body information 220, and link information corresponding to the hyperlinks (that is, linked homepage addresses) is connected to the same server. The case is common. Accordingly, the e-mail server 120-n may determine whether a plurality of link information included in the body information 220 corresponds to the same server in order to determine whether the received e-mail is a news mail.

In step S330, if the plurality of link information included in the body information 220 of the received email corresponds to the same server, the header information 210 of the email is analyzed. That is, the email server 120-n may analyze the header information 210 of the email to more accurately determine whether the received email is a news mail.

In operation S335, it is determined whether message ID information and / or return path information included in the header information 210 is pre-stored in a storage space provided with the return information. As a result of the determination, if previously stored, it is determined whether the preset keyword is included in the subject information included in the header information 210 (step S340).

Since the message ID information and / or the return path information can know the information on the sender terminal 130-p that has transmitted the email, the email server 120-n returns the message ID information and / or return included in the received email. By determining whether the route information is pre-stored in the storage space, it is possible to know whether the e-mail is an e-mail transmitted from the sender terminal 120-p that transmits the newsletter.

In addition, if the subject information of the received e-mail includes a predetermined keyword (for example, news, times, magazine, card, post, etc.), the e-mail server 120-n is likely to be a news mail. The subject information of the received e-mail may be analyzed to determine whether the e-mail is a news mail.

In step S345, if the subject information of the received e-mail includes a preset keyword, it is determined whether the sender name included in the header information 210 is included in the subject information. That is, since the sender name is information on the terminal name preset in the sender terminal 130-p that transmitted the e-mail (for example, the Jiran branch of the Jiran church [admin@jiransoft.com]), the e-mail server 120-n. ) Can be classified as a newsletter if the sender's name is in the subject information. For example, if the sender information of the received e-mail is Jiran Catholicism, and the subject information corresponds to [Granji Catholicism-Mr. Yoon Yun-nam], the e-mail server 120-n includes the sender information in the subject information, so the e-mail is sent to the news. You can classify it as an email.

As described above, the e-mail server 120-n includes a plurality of link information included in the body information 220 in which sender information (for example, e-mail address, IP, etc.) of the received e-mail corresponds to news mail information. Corresponds to the same server, message ID information and / or return path information is pre-stored in the storage space, a preset keyword is included in the subject information, and the sender's name is included in the subject information. Can be classified as. Herein, the case where the received e-mail is classified as a news mail is described only when all of the above conditions (steps S315, S325, S335, S340, and S345) are satisfied. However, even if only one or more of the above conditions are satisfied, the news mail is described. It is obvious that it can be classified as. In addition, since the order in which the above conditions are determined is only divided into the embodiments, it is obvious that the scope of the present invention is not limited.

Meanwhile, if S325, S335, S340, and S345 are not satisfied among the above-described conditions (steps S315, S325, S335, S340, and S345), it may be determined whether the received email is a spam mail (step S360). That is, the plurality of link information included in the body information 220 of the received email does not correspond to the same server, the message ID information and / or the return path information are not pre-stored in the storage space, or preset in the subject information. If the keyword is not stored or if the sender's name is not included in the subject information, the e-mail server 120-n may determine whether the e-mail is spam. This is because if only a part of the above conditions (steps S315, S325, S335, S340, S345) are not satisfied, it is likely that the message is spam.

For example, when a plurality of link information included in the body information 220 of the received email corresponds to the same server, but the sender's name is not included in the subject information, and the subject information does not include a preset keyword, This is because it is likely to be spam. At this time, the method for determining whether the e-mail server 120-n is the spam mail is obvious to those skilled in the art, so a detailed description thereof may be omitted.

In step S365, if it is determined that the received e-mail is a spam mail, the e-mail is classified as spam mail. If it is determined in step S370 that the received e-mail is not spam mail, the e-mail is classified as general mail. Email that is not news mail or spam is likely to be your personal mail.

On the other hand, if the determination result in step S315 is not pre-stored in the storage space provided with the sender information, since the received e-mail is not known from whom the e-mail is sent to the connected central server (110) (step S380).

When the central server 110 receives the email from the email server 120-n, the central server 110 receives an email similar to the email from another email server 120-g (where g is a natural number less than or equal to n). ) Is received or received within a preset time. For example, the central server 110 may determine whether similar mails are received from another email server 120-g, and if not, determine whether similar mails are received within a preset time. Since the news mail is mostly an email sent to a plurality of recipients with the same or similar content, the central server 110 may classify the email as a news mail when a similar mail is received.

Here, the method for determining whether the central server 110 is a similar mail may vary. For example, the central server 110 may determine that an email including the same message ID information and / or return path information as the received email is a similar mail. In addition, the central server 110 may determine that the received e-mail and the body information 220 is similar to the similar e-mail, wherein the central server 110 is a predetermined keyword of the body information 220 of the e-mail ( Hereinafter, an e-mail containing other parts except for a recipient keyword) may be determined as a similar e-mail.

For example, the text information of a news mail sent to a plurality of recipients usually includes a part including the name or name of the recipient (ie, 000, 000, 000, 000, 000, etc.). The remaining parts except for the part including the name or the name of the receiver are generally the same as the body information 220 transmitted to the other receiver. Therefore, when the recipient keyword is set to [you, eh, eh, received], the central server 110 determines that the part including the recipient keyword (ie, the part including the name or name of the recipient) is included in the text. When included at the beginning or the end, it is possible to determine that the remaining body information 220 except for the part including the recipient keyword is the same email as the corresponding email.

Accordingly, the central server 110 receives a similar mail similar to the email received from the email server 120-n or receives it within a preset time (that is, the similar mail is received within a preset time after receiving the email. The e-mail may be determined to be a news mail. Accordingly, the central server 110 may transmit a signal (hereinafter referred to as news information) to inform the email server 120-n that the email is a news mail.

On the other hand, if a similar mail similar to the email received from the email server 120-n is not received, the central server 110 determines that the email is not a news mail and transmits a signal to inform the email server 120-n. Can be.

In step S385, when news information is received from the central server 110, the e-mail is classified as a news mail and stored (step S390). If the e-mail containing the header information 210 similar to the header information 210 of the e-mail is received later by the step S390, the e-mail is transmitted without transmitting the e-mail to the central server 110 (that is, without performing the step after the step S380). Obviously, the server 120-n itself will be able to identify the email as a newsmail.

Meanwhile, when information other than news information is received from the central server 110, the email server 120-n performs an operation for classifying the email as spam mail or general mail. That is, the e-mail server 120-n may classify the e-mail as a news mail when news information is received from the central server 120-n, and classify it as a spam mail or a general mail when other information is received. The subject that determines whether the e-mail is spam or general mail may be an e-mail server 120-n or a central server 110.

Therefore, when the e-mail received from the e-mail server 120-n is not a news mail, the central server 110 may determine whether the e-mail is spam. If the e-mail server 120-n determines that the e-mail is spam. Can be sent to. In addition, when the received e-mail is not a spam mail, the central server 110 may determine that the e-mail is a personal general mail and transmit general information to the e-mail server 120-n. Accordingly, the e-mail server 120-n may classify the e-mail according to the information received from the central server 110. However, if the central server 110 only determines whether it is a news mail, the e-mail server 120-n may determine whether the e-mail is spam or general mail (ie, steps S360 to S370). ).

As described above, the e-mail server 120-n may automatically classify the received e-mail by determining whether the received e-mail is news mail, spam mail, or general mail. Therefore, according to the present invention, the news mail is classified as spam mail, thereby preventing the recipients from receiving it. Furthermore, the news mail is automatically classified with the general mail, so that the user can easily search for the news mail even after time passes. Can be. In addition, as described above, the subject performing the above-described steps may be the user terminal 130-m (particularly, the receiver terminal 130-k) as well as the e-mail server 120-n.

In the above description, the e-mail server 120-n determines that the e-mail satisfying all of the conditions of step S315, step S325, step S335, step S340, and step S345 is a newsmail. Emails satisfying the above conditions can also be determined as news mails. That is, the e-mail server 120-n may determine an e-mail that satisfies three or more of the five conditions (that is, the conditions of the steps S315, S325, S335, S340, and S345) as a news mail. have. In addition, the preset number here may be changed by settings of the operator of the e-mail server 120-n and / or the user of the receiver terminal 130-k.

4 is a flowchart illustrating an email classification method according to another embodiment of the present invention.

Each step to be described below may be performed in the central server 110 and / or the e-mail server 120-n described with reference to FIG. 1. In addition, the central server 110 and the email server 120-n may be connected by wire or wirelessly through the network 140.

In step S400, when the e-mail server 120-n receives an e-mail (hereinafter referred to as an outgoing e-mail) transmitted from the sender terminal 130-p, the e-mail server 120-n transmits the received e-mail to the central server 110 (step S410). ).

In step S420, the central server 110 determines whether similar mail similar to the originating email has been received. That is, the central server 110 may determine whether a similar mail similar to the originating email is received from another email server 120-g, and if not, determine whether the similar mail is received within a preset time. Since the newsletter is mostly an email sent to a plurality of recipients with the same or similar content, the central server 110 may determine that the outgoing email is a news mail when the similar mail is received. Here, the method of determining the similar mail by the central server 110 may be the same as or similar to the method described with reference to FIG. 3, and thus a detailed description thereof will be omitted.

In step S425, when a similar mail similar to the outgoing email is received or received within a preset time, the central server 110 determines whether the outgoing email is a news mail according to a preset method. This is because even if an e-mail similar to the outgoing e-mail is received from another e-mail server 120-g, it is impossible to exclude the possibility that the outgoing e-mail is spam. Therefore, even if a similar mail exists, the central server 110 corresponds to the same server with a plurality of link information included in the body information 220 of the outgoing email, or the sender name is included in the subject information, or the subject information. It may be determined whether a preset keyword (news, news, etc.) is included to examine whether the outgoing email is a news mail. That is, the central server 110 may perform steps S415 to S450 described above with reference to FIG. 3 to check whether the outgoing email is a news mail.

In step S430, if it is determined that the outgoing e-mail is a news mail, the central server 110 generates news information and transmits it to the e-mail server 120-n, and the e-mail server 120-n receiving the news information sends outgoing e-mail. Are classified as news mail (step S440).

On the other hand, if it is determined that the originating email is not a news mail, the central server 110 determines whether it is a spam mail (step S450). As a result of determination, when it is determined that the outgoing e-mail is spam, the central server 110 generates spam information and transmits it to the e-mail server 120-n (step S445), and the e-mail server 120-n receiving the spam information. Classifies the outgoing email as spam mail (step S460).
