<generating the various embodiments of recommending data>
Fig. 5 schematically shows the flow chart of the project recommendation logic using the viewing historical data broadcasting home shopping about data according to embodiment of the present disclosure.
In the embodiment of Fig. 5, in step S1100, service server is utilized to broadcast the history log collection history log based on the ID of Set Top Box of home shopping from data according to the item recommendation method of the disclosure.History log is relevant to the viewing history being used for from the T commercial data broadcast of Set Top Box transmission.In a word, the viewing history log data based on Set Top Box ID is collected.
Based on the viewing history of Set Top Box ID can include following at least one: by Set Top Box by the project information of data broadcast home shopping viewing, project category information, specific event information, about the information of the viewing when carried out and about the information that have viewed how many times.Project information can include item price (selling price, purchase framework, the market architecture and discounted cost), classification of the items, brand, manufacturer, price rebate history and search word information.Project category information can include area project, poster project, the project evaluation, sales volume and prior information.Specific event information can include specific event group, specific event classification, specific event project, Event Priority, gerentocratic ID and click history.
When user only have viewed broadcast without utilizing his or her long-range control to have selected certain menu, then it is essential that collect and determine the data of the project that user has watched.In order to determine viewing data in this case, the Set Top Box that can analyze DTV accesses service server and watches the time-bands (namely Set Top Box enters the time-bands of the homepage of data broadcasting service) of home shopping broadcast, and the item code with organization table Data Matching and by corresponding time-bands includes in viewing history.
It follows that service server analyzes viewing data history daily record based on Set Top Box ID to generate project recommending data based on filtering of user with at least one in project-based filtration treatment by using.Each during the two processes can be performed.
In the illustrative embodiments of the disclosure, can be extracted in scheduled time slot based on the filtration of user and have viewed this user and (can be represented by Set Top Box ID, this is because he or she is identified by Set Top Box ID, lower with) list of the project of another user of reference items purpose of watching viewing to be to generate the filter result based on user.In a word, it is possible to the viewing history based on the second Set Top Box ID of the project having been viewed by by the first Set Top Box ID viewing carrys out filtering items.Filter result based on user can be stored in a DB.
And, project-based filtration can extract the list of the project that user watches in scheduled time slot to generate project-based filter result.For example, it is possible to select the list of project that user watched in a week.Project-based filter result can be stored in the 2nd DB.
The filter result based on user and the project-based filter result that are generated can be aggregated and be stored as project recommendation data.When performing such filtration, generate the pond of recommended project and therefore can build the content recommendation DB on the content area that will be shown in home shopping broadcasting user interface 100.When the large number of recommended project, it is possible to push various recommended project information and when the number of project is less and can not guarantee recommended project fully, it is possible to repeat same recommended project information.In the illustrative embodiments of the disclosure, it is possible to the reference number of recommended project is set.Such as, reference number can be eight.Can also be ten or six with reference to number.Reference number purpose is arranged has meaning in the following cases.
Step S1210 and the S1230 of the disclosure is based on historical information, its instruction is the filtration based on user and " viewing of user " of project-based filter identification by Set Top Box ID, and when there is new subscriber or when causing almost without viewing history owing to seldom watching data broadcast home shopping, it is impossible to enough in filtering and analyze the significant data of acquisition.And, such situation can there is limitation in that, only can repeatedly recommend a small amount of project.Therefore, when in the exemplary embodiment, when project recommendation data are less equal than the recommended project of Pre-set reference number, the list of the frequently project of viewing can be extracted from the project that all users watch scheduled time slot, this list is stored in the 3rd DB and is added to project recommendation data.Therefore, even if not guaranteeing recommended project fully merely with DB and the two DB, it is also possible to guarantee enough project recommendation data.
User for not having viewing history the statistical data of all users can also be utilized to provide default recommendation project data.
Such as it is summarized as follows.The viewing history built in the service server of the disclosure recommends three data of extracted as the recommended project based on individual.First, the list of the project that user (the first Set Top Box ID) watches in specific time period is extracted as recommending data.Secondly, the list of the project watched by another project that have viewed the project that user (the first Set Top Box ID) watches in specific time period is extracted as recommending data.3rd, in specific time period, the list of the project of user (N number of Set Top Box ID) most frequent viewing is extracted as recommending data.It addition, the data first extracted are added to the data secondly extracted to generate recommended project pond.When belonging to the number of recommended project in recommended project pond less than Pre-set reference number (that is, eight), it is possible to add the data of the 3rd extraction to generate the list of recommended project.Then, it is possible to change the recommended project being exposed to user interface 100 when user accesses service server, and eight recommended projects can be exposed when user enters the recommended project page.Will be described in detail below.
After step S1210 and 1230, in step S1310 and 1330, it is possible to by weight assignment to the project in project recommendation data so that carrying out preference recommendation.
The weight based on user in step S1310 may refer to task the weight by have viewed with reference to the certain number of times of project or the project of another above user viewing.With by compared with having been viewed by the project watch less than another user of certain number of times with reference to project, the project being assigned with weight can be preferably recommendation.With reference to Fig. 7, relevant particular implementation is described.
And, may refer to task by the weight continuing to watch the project of another user of reference items purpose viewing within equal or longer than the time of certain time based on the weight of user.With by compared with continuing to watch the project of reference items another user of purpose viewing within the time being shorter than certain time, the project being assigned with weight can be preferably recommend.Can by using such weight, according to user, project viewing time is carried out ranking.
Project-based weight in step S1330 can be following weight, project that it is assigned in scheduled time slot user frequently watches or belong to same category of project, or the project watched repeatedly, continually on the different dates or belong to same category of project.Based on such project, user can be grouped.Compared with other project, the project being assigned with weight can be preferably recommend.Therefore, it is possible to the project do not watched by first user in the project of second user's viewing in same group is recommended first user efficiently.
By such process, service server can build the project recommendation pond based on Set Top Box ID in step S1400.It addition, it determines the content recommendation and recommended project that the content area at home shopping broadcasting user interface of DTV includes.
By such process, the content recommendation (such as, the region 140 in Fig. 4 or other content area) that specific project is recommended anyone of the content area at home shopping broadcasting user interface 100 can change according to user.In a word, the beholder of viewing the same family shopping broadcast simultaneously has different TV image.
And, in the disclosure, the step S1400 of recommended project can recommend new project based on machine learning when entering channel.Therefore, it is possible to user interface is configured to same beholder can have the different content recommendations being shown on content area simultaneously.
Fig. 6 represents the example for recommending the filtration based on user in the logic of content recommendation according to the disclosure.Pass through Fig. 6, it is possible to learn how to recommend the project by have viewed another user of the reference items purpose viewing watched by a certain user.
Assume that Robert have viewed project A to D, Kim and have viewed project B, and Lee have viewed project B, C and E.Service server can identify this situation by viewing daily record.
First, discuss the disclosure service server by project-based filtration to which project Robert recommends.The project jointly watched due to Robert, Kim and Lee is project B, and therefore, project can be with reference to project.
Kim and Lee is taken as have viewed other user with reference to project B.Kim has not seen any project except reference project B.Lee also have viewed project C and E except reference project B.Therefore, have viewed the project of other user of reference items purpose viewing of Robert viewing is project C and E, and the project do not watched by Robert in the project of Kim and Lee viewing is project E.Service server can also recommend have viewed project C and the E of other user of the reference items purpose viewing watched by Robert to Robert.For easy description, Fig. 6 illustrates the project that in the project recommending other user viewing, he or she does not watch.
At Kim, Robert and Lee as when have viewed other user of reference project B of Kim viewing, Robert have viewed project A to D and Lee have viewed project B, C and E.Therefore, have viewed the project of other user viewing of the reference project B of Kim viewing is A, C, D and E, and the disclosure can to Kim recommended project A, C, D and E.
At Lee, Robert and Kim as when have viewed Lee other user of reference items purpose watched, Robert have viewed project A to D and Kim have viewed project B.Therefore, the project of other user viewing having been viewed by the reference project B of Lee viewing is project A, C and D.When assuming to recommend the Lee project do not watched, the disclosure can to Kim recommended project A and D.
But, owing to the item recommendation method of the disclosure does not only use project-based filtration to carry out recommended project, therefore, the recommended project in Fig. 6 does not limit the disclosure.
It can be appreciated that there is Robert and Lee also have viewed the history of project C except reference project B.Namely, it is possible to Robert and Lee is categorized as association user similar in project interested.In this case, the user that have viewed a lot of project can be applied weight as association user and when recommended project to by the project of association user's viewing by the item recommendation method of the disclosure.By applying weight, first recommend the project by similar in project interested Robert viewing can cause bigger interest and therefore for Lee to Lee, by the sale increase using such system that data can be promoted broadcast.
Fig. 7 illustrates that the project-based filtration of the disclosure and weight apply.There are two kinds of situations.
First, first the recommendation logic for the left hand situation with reference to project AAA is described.Illustrate that project and the user 1 and 2 of user 1 and 2 viewing by the user as viewing reference project AAA have viewed respective items purpose number of times.N1 represents that user have viewed reference items purpose number of times and user have viewed respective items purpose number of times.Such as, user have viewed with reference to project AAA twice and watches reference project cccc79 time.Have viewed the project (cccc to iiii) that the user 1 with reference to project AAA watches and can be recommended to have viewed the user 2 of same reference project AAA.
In another embodiment applying weight, the project (such as, user 1 have viewed the cccc of 79 times) that the item recommendation method of the disclosure frequently can be watched to user 1 in the project that user 2 preferably recommends (compared with other project) user 1 to watch.
It follows that describe the recommendation logic of the right hand situation for reference project BBB.Assume that user 1 to 5 is as have viewed the user with reference to project BBB.As directed, it can be seen that user 1 have viewed reference project 36 times.The item recommendation method of the illustrative embodiments according to the disclosure can preferably recommend (compared with the project that other user watches) more frequently to watch, than other user, the project (such as, oooo) that reference items purpose user 1 watches.
<pictured scene>
