Step 308: preserve this relevance table, finish current flow process.
Setting up the association between the content in the IPTV system is to realize efficient basis of recommending, only between content, set up effectively related, could guarantee when the user selects certain content, obtain other content relevant with this content, and find metadata corresponding information by the sign of this content and other content, comprise in the details page of the metadata information of this content and placard in output, the inlet information that further shows and other content that user be most interested in relevant with this content, this inlet information can content title, the attributes of chained address or content etc., the user can jump to the details page of other content according to this inlet information.
Below in conjunction with table 1, the relevance grades according to play content correspondence in the content play situation update content contingency table is described.Suppose that content 1 is to content 4 these four contents in the relevance table, receive the request message that the user asks play content 1 this moment, if default relevance grades is 2, then according to this relevance table find with the relevance grades of content 1 be content 2 and content 4 greater than 2 content, therefore to user side output content 1, the information of content 2 and content 4, for example exported the title of foregoing respectively, attribute and brief introduction, if user side is finally selected play content 4, then play situation update content contingency table 1, the content in this table 11 and the relevance grades of content 4 and the relevance grades of content 4 and content 1 are added 1 respectively according to this.
When having created the existing content of fresh content or deletion among the IPTV, need safeguard related information, second embodiment of corresponding the inventive method, the flow process that the content contingency table is safeguarded as shown in Figure 4:
Create or delete a content among the step 401:IPTV.
Step 402: receive Notification of Changes at this content.
Step 403: in the relevance table, increase or delete this content and other content between relevance grades.
Step 404: preserve the relevance table after safeguarding.
The 3rd embodiment flow process of information output method of the present invention as shown in Figure 5, the information output flow process when this embodiment shows relevance information for user's custom table and relevance table, still finish information output by the EPG subsystem in the IPTV system:
Step 501:EPG subsystem receives the request message that comprises the play content sign.
Step 502: determine type and subclass that this play content is affiliated.
Step 503: when determining that by user's custom table the type is the user's interest type, search the relevance table of this subclass according to content identification.
Step 504: obtain and the relevance grades of play content other content greater than default relevance grades.
Step 505: the information of output play content and other content.
Step 506:EPG subsystem obtains the broadcast situation of the content of outputting content information.
Step 507: according to the relevance grades of this play content correspondence in the content play situation update content contingency table.
Content quantity in the IPTV system is bigger, and when surpassing 10000 contents, then the relevance number of degrees in the relevance table will reach 100,000,000, and promptly along with the growth of content quantity, the relevance grade in the relevance table will increase by geometric progression.And, because table 1 has only been described incidence relation between all the elements from two dimension angular, therefore can't further embody different classes of, and the relation between the content of the different subclasses of same classification, such as, the classification of dividing different content from dimension can comprise age, country origin, the story of a play or opera, protagonist etc., is example with the country origin, and further the subclass of dividing can comprise China, Korea S, the U.S. etc.Therefore, can classify in dimension in conjunction with user's the custom of watching, comprise the age with the dimension classification, country origin, the story of a play or opera, produce and act the leading role and be example, the initial user who generates is accustomed to showing as shown in table 2 below, this user is accustomed to showing the level of interest to the content of broadcast corresponding to all users in this system, suppose that the content in this IPTV system is divided into the age from dimension, country origin and the story of a play or opera three classes, wherein, age is divided into the seventies, the eighties and the nineties three subclasses, country origin is divided into China, three subclasses of the U.S. and Korea S, the story of a play or opera is divided into comedy, gun battle movie, three subclasses of science fiction film, the generating mode that the user is accustomed to showing is as follows: the user can select own interested classification and subclass by the terminal interface when opening an account in advance, and carry out record by the EPG subsystem, comprehensive all user's interest of EPG subsystem are classified and subclasses then, for example when surpassing 50 percent user all when interested in a certain subclass, think that then the user is interested in this subclass, when less than 50 percent user when interested in a certain subclass, think that then the user loses interest in to this subclass, need to prove, content more can classified on the various dimensions at the concrete time-like that divides, and each classification can further be subdivided into more subclasses, table 2 is only done exemplary illustration, and the numerical value in the following table 2 list item cells is used for representing all users that the interested subclass initially selected according to the user comprehensively obtains level of interest to each classification subclass:
Table 2
| Age | The seventies | The eighties | The nineties |
| 0 | ∝ | 0 | |
| Country origin | China | The U.S. | Korea S |
| ∝ | 0 | ∝ | |
| The story of a play or opera | Comedy | Gun battle movie | Science fiction film |
| ∝ | ∝ | 0 |
Last table 2 carries out related watching habit table for the user with the classificatory content of various dimensions, wherein " 0 " expression user loses interest in to the content of this subclass, " ∝ " expression user is interested in the content of this subclass, when the content of new type or subclass occurring in the system, then can expand automatically, add the level of interest of access customer type under the fresh content or subclass to above-mentioned user's custom table.In the IPTV system, user property metadata that each user is corresponding, the user property metadata is used to describe user's basic condition, for example information such as user name, user's pet name, subscriber payment account number.The user can select whether to add access customer custom table by add " whether safeguarding the custom table " parameter in metadata, promptly when the user opening an account or professional use in select to safeguard above-mentioned user's custom table, then the IPTV system considers the interest parameter of this user to every kind of content type subclass when the generation user is accustomed to showing, when the user no longer selects to safeguard the watching habit table, during then IPTV system-kill user is accustomed to showing to interest parameter that should the user, perhaps freeze this user's interest parameter, reselect up to this user and safeguard this user's custom table.When the user reselects when safeguarding this user's custom table, system can point out whether use freeze before this user's interest parameter, this user's that still resets interest parameter.Be accustomed to showing to realize understanding that all user watched customs in the IPTV system are distributed by above-mentioned user.
Because each dimension type also comprises the subclass that quantity does not wait, therefore can select the further relevance table that generates at this subclass of part subclass in the part classification flexibly, user's interest dimension type is that the subclass " China " of " country origin " is an example in the above table 2, country origin-China-relevance the table that generates is as shown in table 3 below, supposes that content relevant with " China " in this table 3 has 5:
Table 3
| Content 1 | Content 2 | Content 3 | Content 4 | Content 5 | |
| Content 1 | 0 | 3 | 2 | 1 | 7 |
| Content 2 | 3 | 0 | 5 | 6 | 0 |
| Content 3 | 2 | 5 | 0 | 3 | 0 |
| Content 4 | 1 | 6 | 3 | 0 | 4 |
| Content 5 | 7 | 0 | 0 | 4 | 0 |
Preserved the metadata of content in each relevance table in the IPTV system, metadata is used to describe the basic condition of content, comprises content name, content copyright information, content life cycle information, content evaluation information etc.Further can in metadata, add " whether maintenance content contingency table " parameter and select whether in the content corresponding contingency table, to safeguard the relevance grades between this content and other content, for example, can when content release, this parameter be set to " TRUE " or " FALSE ", wherein the TRUE correspondence is safeguarded the relevance grades between this content and other content in the relevance table, and the FALSE correspondence is not safeguarded the relevance grades between this content and other content in the relevance table.
In order to generate the relevance table of a plurality of subclasses of respective user custom table in the above-mentioned IP TV system, need use the situation of the specific subclass content under the particular type in this system to carry out correlation analysis to the user, the flow process that content is carried out correlation analysis as shown in Figure 6:
Step 601: the relevance table of a plurality of subclasses of initialization is 0 with the relevance grades assignment between all the elements.
Step 602: be PID_I with this content ID assignment when receiving the request message of certain content information of broadcast that the user sends.
Step 603: search for M content that this user watched and the subclass of obtaining this user's interest type according to user's custom table.
Step 604: read a content ID who does not read in M the content in order, each content ID assignment is PID[i], the value of i from 1 to M.
Step 605: judge PID_I and PID[i] whether consistent, if then return step 604; Otherwise, execution in step 606.
Step 606: each subclass that travels through the user's interest type in order.
Step 607: judge PID_I and PID[i] whether all belong to the current subclass that traverses, if then execution in step 608; Otherwise, return step 606.
Step 608: with [PID_I, PID[i] in the current subclass] and [PID[i], PID_I] relevance grades add 1.
Step 609: judge whether current subclass is last subclass of user's interest of traversal, if then execution in step 610; Otherwise, return step 606.
Step 610: judge whether current i equates with M, if then execution in step 411; Otherwise, return step 404.
Step 611: preserve the relevance table of all subclasses, finish current flow process.
Below in conjunction with table 2 and 3, the relevance grades according to play content correspondence in the content play situation update content contingency table is described.Suppose to receive the request message of content 1 in user's playlist 3, the classification that at first obtains content 1 belongs to " country origin ", subclass belongs to " China ", obtain the user by user's custom table 2 interest level of this subclass is " ∝ ", the relevance table table 3 of further related this subclass, if default relevance grades is 2, then according to this relevance table 3 find with the relevance grades of content 1 be content 2 and content 5 greater than 2 content, therefore to user side output content 1, the information of content 2 and content 5, for example exported the title of foregoing respectively, attribute and brief introduction, if user side is finally selected play content 2, then play situation update content contingency table 1, the content in this table 11 and the relevance grades of content 2 and the relevance grades of content 2 and content 1 are added 1 respectively according to this.
Need to prove that the initial user's custom table that generates also can further upgrade according to the request of user's play content and safeguard, the flow process that above-mentioned user's custom table is carried out Dynamic Maintenance as shown in Figure 7:
Step 701: the request message of receiving certain content information of broadcast that the user sends.
Step 702: the identity of determining this user.
Step 703: retrieve this content affiliated type and subclass.
Step 704: whether the list item of judging this subclass of active user's correspondence in user's custom table is " ∝ ", if then execution in step 706; Otherwise, execution in step 705.
Step 705: the list item of the subclass of type under this content in user's custom table is added 1.
Step 706: judge whether the type and the subclass that retrieve are last subclass, if then execution in step 707; Otherwise, return step 703.
Step 707: the user who preserves after upgrading is accustomed to table, finishes current flow process.
If the level of interest when certain subclass during the user after the above-mentioned renewal is accustomed to showing is initial is " 0 ", when through the numerical value of repeatedly playing the back level of interest above all numbers of users 50 percent after, the level of interest that can upgrade this subclass is " ∝ ", makes it become the user's interest subclass.
