When proposing a product, the product proposal unit 210 sets a user ID indicating the proposed user, a product ID indicating the proposed product, a reward ID indicating reward information, a proposed date and time, and a "false" reward flag. A history can be created and added to the proposal history storage unit 233.

The structure information acquisition unit 211 accesses the e-mail server 42 that manages the e-mail addressed to the user. The structure information acquisition unit 211 can acquire only the envelope (ENVELOPE) included in the e-mail from the e-mail server 42 according to a protocol such as IMAP (Internet Message Access Protocol). Here, the structural information acquisition unit 211 does not acquire the message body of the e-mail (BODY, BODYSTRUCTURE, etc.) or the entire e-mail (ALL, RFC822, etc.) or BODYSTRUCTURE), but acquires only the envelope. Further, the structural information acquisition unit 211 stores the envelope in the primary storage device instead of storing it in the secondary storage device.

Further, the structural information acquisition unit 211 can acquire a message header (RFC822.HEADER, etc.) included in the e-mail in place of the envelope or in addition to the envelope. Also in this case, the structural information acquisition unit 211 does not acquire the information including the message body. The structure information acquisition unit 211 also stores the message header in the primary storage device instead of storing it in the secondary storage device.

The determination unit 212 determines whether or not the envelope satisfies the condition. The determination unit 212 verifies the envelope acquired by the structural information acquisition unit 211 and stored in the primary storage device. The determination unit 212 determines whether or not the envelope satisfies the condition by using, for example, a classifier that classifies whether the content of the envelope e-mail is private content or is related to commercial transactions, which is learned by machine learning. It may be a process. The determination unit 212 can delete the envelope from the primary storage device when the envelope does not satisfy the condition.

The determination unit 212 can also determine whether or not the message header satisfies the condition. When the structure information acquisition unit 211 acquires the message header, the message header stored in the primary storage device can be verified. The determination unit 212 can delete the message header from the primary storage device when the message header does not satisfy the condition.

The e-mail acquisition unit 213 can acquire the message body included in the e-mail from the e-mail server 42 when the envelope satisfies the condition. The e-mail acquisition unit 213 may acquire the message header and the message body from the mail server when the envelope satisfies the condition. Further, the e-mail acquisition unit 213 may acquire the entire e-mail data (ALL, FULL, RFC822, etc.) including the message body from the e-mail server 42.

The e-mail acquisition unit 213 can remove the envelope from the primary storage device before acquiring the message body.

Further, when the structure information acquisition unit 211 has acquired the message header and the determination unit 212 satisfies the condition of the message header (or both the envelope and the message header), the e-mail acquisition unit 213 sends a message. The body can be obtained from the email server 42.

The e-mail acquisition unit 213 can delete the message header (or both the envelope and the message header) from the primary storage device before acquiring the message body.

Extraction unit 214 analyzes the message body of the e-mail and extracts transaction information. The extraction unit 214 can acquire transaction information from the message body, for example, by applying a rule for analyzing the message format prepared in advance. In the rule, for example, what kind of information is described in what format can be specified by a regular expression or the like. Further, the rules may be prepared for each seller of the product (EC site, direct sales site, etc.). The transaction information can include at least information that identifies the product (for example, a manufacturer name or a product name). The extraction unit 214 can register the extracted transaction information in the transaction information storage unit 234. The extraction unit 214 can also use the message header of the e-mail for the extraction process of the transaction information. For example, the extraction unit 214 may extract the message ID from the message header and include it in the transaction information. Further, the extraction unit 214 may use the sender (From) included in the message header to determine the EC site name and the store name.

Further, the extraction unit 214 may analyze the message header and the message body to extract transaction information. For example, the rule for the message header and the rule for the message body may be stored separately.

The extraction unit 214 can delete the message body after analyzing the message body. When the extraction unit 214 analyzes the message body and the message header, the extraction unit 214 can delete the message header together with the message body.

The reward giving unit 215 can give a reward to the user according to the fact that the transaction information related to the proposed product can be extracted from the e-mail (message body). For example, when the extraction unit 214 succeeds in extracting the transaction information, the reward giving unit 215 has a proposal history (reward flag is "false") corresponding to the product included in the extracted transaction information and the user to whom the e-mail is sent. ”) Is registered in the proposal history storage unit 233, the user can be rewarded. The reward giving unit 215 can set "true" in the reward flag of the transaction information and the proposal history after rewarding the user.

The reward giving unit 215 can determine the content (type and amount) of the reward given according to the reward information corresponding to the product of the extracted transaction information. When the extracted transaction information satisfies the condition included in the reward information, the reward giving unit 213 grants the reward set in the reward information (or the reward determined based on the reward information) to the user. be able to.

The reward granting unit 215 may grant rewards regardless of the reward information. For example, the reward giving unit 215 can give the user the same reward or different rewards according to the attributes of the user depending on the fact that the transaction information can be extracted from the message body of the e-mail. In addition, the reward giving unit 215 can also determine the type and number of rewards according to the extracted transaction information. For example, the reward giving unit 215 can determine the reward according to the number and amount of products (purchased products) included in the transaction information. Further, the reward giving unit 215 may change the type and number of rewards given according to the past purchase data of the user stored in the transaction information storage unit 234.

Further, the reward giving unit 215 may determine the type and amount of rewards to be given by lottery. The reward giving unit 215 can decide, for example, whether or not to give a reward such as a coupon or a present by lottery. Further, the reward giving unit 215 can determine, for example, the number of points to be given, the rarity and value of the gift to be given, and the like by lottery. In this case, the reward giving unit 215 may, for example, execute the mini game on the user terminal 10 and determine the type and amount of the reward given according to the result of the mini game.

<Operation>
FIG. 4 is a diagram illustrating the operation of the recommendation system of the present embodiment.

The server device 20 recommends a product to the user (S301), and stores the recommended product (recommended product) (S302). The server device 20 extracts transaction information from an e-mail addressed to a user (for example, an e-mail addressed to a user who is a purchaser from a seller who sells a product) (S303). When the transaction information is successfully extracted (S304), the server device 20 searches for the recommended product corresponding to the purchased product (S305), and if there is a recommended product (S306: YES), rewards the user (S306: YES). S307).

<Transaction information extraction process>

The present invention can be modified and improved without departing from the spirit thereof, and the present invention also includes an equivalent thereof.

For example, in the present embodiment, the e-mail containing the transaction information is specified only from the envelope, but the present invention is not limited to this, and the message header is acquired from the e-mail server 42 in addition to or in place of the envelope. By doing so, the e-mail to be processed may be specified depending on whether or not the message header satisfies the filter condition. In this case, the message header can also be stored in the primary storage device and not stored in the secondary storage device.

Further, for the envelope satisfying the first filter condition, only the message header is acquired from the e-mail server 42 without acquiring the message body before the message body is further acquired, and the message header is further second. It may be determined whether or not the filter condition of is satisfied. In this case as well, the message header can be stored in the primary storage device and not stored in the secondary storage device.

Further, in the present embodiment, the transaction information is acquired only from the message body, but a part of the transaction information may be acquired from the message header as well. In this case, in step S326 of FIG. 5, transaction information can be extracted from the message body and the message header.
