The user identifier (UID) means a value for distinguishing a user. When the terminal 10 executes the script, the terminal 10 firstly determines whether the user identifier value is stored in the cookie of the web browser. If the user identifier is stored, (30). On the other hand, if the user identifier is not stored in the cookie of the web browser, information that can identify the user is generated by combining an arbitrary numerical value and the generation time (for example, 33619442.1366005959274), and transmits the generated information to the

Referring to Equation (1), the jacquard similarity between two items indicates the number of users who visited both items (the number of users who accessed both web pages displaying two items) The number of users who have accessed at least one of the displayed web pages - the number of users who access both web pages displaying two items) is calculated. As a result, the more similar the users who visited both items, do. For example, if the number of users connected to the web page displaying the A item is 20, the number of users accessing the web page displaying the B item is 10, and the number of users visiting the web page displaying the A and B items When the number is 5, the calculation result of jacquard similarity is 5 / (20 + 10 - 5) = 1/5.

Referring to Table 7, the SCORE value represents a value obtained by calculating the similarity between the item and the recommendation item according to the recommendation algorithm, and the METHOD represents an identification number for the recommendation algorithm used in the similarity calculation.
The service device 30 (particularly, the data processing unit 222) may convert the recommended calculation result calculated in step S305 into a data format suitable for providing to the web server 20 (S307).

Referring to Table 9, the hash value is a value calculated so as not to store the recommendation item list for the item in a case where the recommended item list recommended for the specific item is the same, and includes a service identifier (SERVICE_ID) The identifier (ITEM_ID) and the recommendation item identifier (RECOMMENDED_ITEM_ID) are combined into one string, and then the hash function is applied to the combined string. By using such a hash value, even if the recommendation score of the recommendation items belonging to the recommendation item list is changed unless the recommendation item belonging to the recommendation item list is changed or the recommendation item belonging to the recommendation item list is changed, The item list may not be updated. That is, since the recommendation score for the recommendation item is not included in the variable for calculating the hash value, if the recommendation score of the recommendation item is changed when the recommendation item list is calculated again the next day, If the order is not changed, the hash value is not changed.
And the COUNT value indicates the number of recommendation items and how many items are recommended for a specific item. The JSON value includes information on a recommended number of items corresponding to the count value, and may include, for example, a recommendation item identifier, recommendation score, and recommendation algorithm information.
The service device 30 (in particular, the recommendation result providing unit 224) performs post-processing on the calculated recommendation result (or recommendation item list) and then recommends recommendation to the

The service apparatus 30 (in particular, the feedback processing unit 225) may collect the feedback of the user and reflect the feedback to the recommendation (S311).
The feedback of the user can be calculated according to the user's click rate, and the recommended view log data and the user's recommended click log data can be collected to calculate the click rate.
First, a method of collecting click log data will be described.
As a first method, when the recommendation item included in the recommendation item list of the user is clicked, the user is redirected to the

For example, each referral item (s) in the referral item list may include a link URL in the format "http://api.recopick.com/VERSION/banner/SERVICE_ID/pick?source=SOURCE_ITEM_ID&pick=TARGET_ITEM_ID&method=ALGORITHM"Lt; / RTI > The link URL of each recommendation item includes version information of a recommendation item list to which the recommendation item belongs, a service identifier, a source item (an item to be a target item for which a recommendation item is displayed), a target item (a recommendation item ) Identifier, algorithm information for calculating the selected recommendation item, and the like.
For example, if items 132, 178, and 200 are recommended in the item 59 of the

As a second method, a predetermined parameter is added to a variable constituting a link of the recommendation item, and if the predetermined specific parameter described above exists in the user's visit URL information in the user log data collected in step S301, It can be judged by a click. That is, data including a predetermined parameter in the visit URL can be extracted from the user log data and stored as click log data. For example, if recopick = METHOD is added to the link variable of the recommendation item and the recopick exists in the user's visit URL in the user log data, it can be judged as a recommendation click. After confirming the item identifier (ITEM_ID) in the reference address (Referrer) information, the source item identifier can be confirmed using the item identifier (ITEM_ID).
