Return step S3.
In an application example of method described in Fig. 5, in advance under each keyword i ∈ W and each Assisted Keyword j thereof, be described advertisement subset A
ijin each advertisement a bid is set, therefore described step S5 comprises following concrete implementation step:
Step S51. calculates described additional key word set T
win the appraisal of each Assisted Keyword;
Step S52. is by described T
wthe Assisted Keyword of the setting quantity that middle appraisal is the highest forms described S
w;
Step S53. is by described S
win the link of each Assisted Keyword, by the sequence of appraisal size, and be presented on described advertisement position.
In described step S51, the valuation methods of each Assisted Keyword is as follows.Suppose additional key word set T
win the appraisal of each Assisted Keyword, clicking rate and price be respectively e (w, j), CTR (w, j) and p (w, j), wherein j=1,2 ..., P
w, then have:
e(w，j)＝CTR(w，j)·p(w，j)；(j＝1，2，...，P
w)
Wherein Assisted Keyword price p (w, j) (j=1,2 ..., P
w) computing method as follows.Be that example illustrates with the computing method of p (w, 1).Suppose the advertisement subset A under keyword w and Assisted Keyword t (w, 1)
w, 1in have 100 advertisements, then Assisted Keyword price p (w, 1) equals advertisement subset A
w, 1the appraisal sum of front R the advertisement that middle appraisal is maximum, R is setting constant.The valuation methods of advertisement has two kinds: the first clicking rate being advertisement value equals advertisement is multiplied by the bid of advertisement, and the second is the bid that the appraisal of advertisement equals advertisement.The clicking rate of advertisement by obtaining the statistics of user's click logs, also can be obtained by clicking rate prediction model.Bid described in this valuation methods refers to each clicking cost CPC of advertisement.
The clicked number of times that the user clicking rate CTR (w, j) of Assisted Keyword equals Assisted Keyword represents number of times divided by this Assisted Keyword.When determining the initial value of CTR (w, j), keyword t (w, j) can be rendered on each advertisement position equably and carrying out number of clicks statistics again.In addition because forward advertisement position clicking rate is higher than the clicking rate of advertisement position rearward, therefore when adding up number of clicks, the number of clicks of forward advertisement position will be greater than the parameter of 1 divided by one when adding up, advertisement position is more forward, divided by parameter values larger.
Described step S53 is also included in a display name on described advertisement position and is called more link, when the user clicks on such link, according to the appraisal of each described Assisted Keyword, at described additional key word set T
win choose and be not included in described S
win the Assisted Keyword of setting quantity, and by the link push of Assisted Keyword selected to the step on described advertisement position.
In an application example of method described in Fig. 5, in advance to each keyword i ∈ W and each Assisted Keyword j=1 thereof, 2 ..., P
i, to advertisement subset A
ijin each advertisement a bid is set, therefore described step 7 comprises following concrete methods of realizing:
Step S71. is according to described signal determination keyword w and Assisted Keyword numbering k;
Step S72. calculates described advertisement subset A
wkin the appraisal of each advertisement;
Step S73. according to described appraisal, at described advertisement subset A
wkin choose at least one advertisement putting give described user u;
In described step S71, determine that the method for keyword w and Assisted Keyword numbering k is as follows.When user uses client submission search inquiry, described server identifies whole inquiry reciprocal process by session identification SessionID.Associating of SessionID and keyword w is recorded in described step S4, obtain SessionID in the step s 7, and find described keyword w according to this SessionID, then according to described keyword w and described Assisted Keyword t (w, k), at described additional key word set T
win determine the numbering k of Assisted Keyword t (w, k).
In described step S72, described advertisement subset A
wkin the valuation methods of each advertisement have two kinds.The first clicking rate being advertisement value equals advertisement is multiplied by the bid of advertisement under described Assisted Keyword t (w, k), and the second is that advertisement value equals the bid of advertisement under described Assisted Keyword t (w, k).
In described step S73, the mode to user u input advertisement comprises and presents an advertisement webpage to user u, eject picture or animation etc.
In an application example of method described in Fig. 5, also comprised the steps: before returning step S3
Step S8. is at described additional key word set T
waccording to the appraisal of Assisted Keyword, select a new subset S '
w, and by described subset S '
win the link of each Assisted Keyword throw in described user u; Wherein said subset S '
wdo not comprise described Assisted Keyword t (w, k).
Step S9. retrieves the last set result relevant with described Assisted Keyword t (w, k) with described keyword w in described server, and described last set result is presented to described user u.
The last set result presented in the Assisted Keyword thrown in the advertisement of throwing in described step S7, described step S8 and described step S9 can be incorporated in a page, present to described user u.
Fig. 6 is the display packing of Assisted Keyword.D10 is the result of page searching of search inquiry " smart mobile phone ", D12 and D13 is respectively advertising area, and each advertising area comprises multiple advertisement position, and D14 is search-results region.On advertising area D11 and D13, throw in first advertisement by broad sense second order price auction mode to user.Multiple advertisement positions simultaneously above advertisement position D11 show the one group of Assisted Keyword selected by this patent method, and what such as select is " trendy, brand, 4G, large-size screen monitors ".The link of each Assisted Keyword takies an advertisement position.After the link of these Assisted Keyword, show the link that a name is called " more ".When user clicks " more " links, system, by whole Assisted Keyword links of current display, is replaced with additional key word set T
win one group of new Assisted Keyword link.Such as T
w=large-size screen monitors, and high pixel, 4G, CPU, sales promotion, brand, treats captain, trendy, operating system }, the S determined is evaluated according to Assisted Keyword
w={ trendy, brand, 4G, large-size screen monitors }.After user clicks " more " links, according to the appraisal of Assisted Keyword, show the link of one group of new Assisted Keyword { sales promotion, treats captain for high pixel, CPU }.
In method described in Fig. 6, whether advertisement position can be used for Assisted Keyword auction is determined at random.Reason is the clicking rate that some new Assisted Keyword need to throw in advance to test it, also has the lower never chance of some Assisted Keyword appraisal to throw in user.Need to determine whether can be used for the auction process of Assisted Keyword at certain advertisement position sometime at random by certain probability in this case.If advertisement position can not be auctioned, then on these advertisement positions, throw in the Assisted Keyword less for the Assisted Keyword and appraisal of testing clicking rate that those are selected at random.For this patent method, only need the moment focusing on Assisted Keyword auction, which Assisted Keyword advertisement position is available.On available advertisement position, throw in the Assisted Keyword of respective numbers according to appraisal size.
Fig. 7 is the back page after clicking Assisted Keyword.After the page of Fig. 6 is clicked Assisted Keyword " trendy ", system returns a new page D20 to user.In the figure 7, D22 and D23 is respectively advertising area, and each advertising area comprises multiple advertisement position, and region D24 shows the search content relevant with " trendy " to " smart mobile phone ".On advertising area D21 and D23, throw in second batch advertisement by broad sense second order price auction mode to user, described second batch advertisement is the bid advertisement relevant with " trendy " to " smart mobile phone ".Above the D21 of region, according to the appraisal of each Assisted Keyword of " smart mobile phone ", show four Assisted Keyword except " trendy ", what such as newly select is " brand, 4G, large-size screen monitors, sales promotion ".If user continues to click Assisted Keyword " 4G ", system returns another new page D20 to user.Wherein D22 and D23 is respectively advertising area, and each advertising area comprises multiple advertisement position, and region D24 shows the search content relevant with " 4G " to " smart mobile phone ".On advertising area D21 and D23, throw in the 3rd batch of advertisement by broad sense second order price auction mode to user, described 3rd batch of advertisement is the bid advertisement relevant with " 4G " to " smart mobile phone ".Above the D21 of region, according to the appraisal of each Assisted Keyword of " smart mobile phone ", show four Assisted Keyword except " trendy " and " 4G ".This process can repeated multiple timesly be carried out, and therefore achieves the times bidding of advertisement.
Fig. 8 is the application of this method on smart mobile phone.Under mobile internet environment, the major obstacle of advertisement putting is that mobile phone screen is little, and throwing in advertisement can affect Consumer's Experience.If only brief ad classification and characteristic information are thrown in user, then can either realize ad auction in less region, Assisted Keyword can be provided to guide to user again.In figure, D30 is the result of page searching of user search keyword " smart mobile phone ".Wherein, region D31 show relevant to keyword " smart mobile phone ", such as, by evaluating linking of one group of Assisted Keyword that size selects, " trendy, brand, 4G, large-size screen monitors "; Region D32 is for showing the Search Results of keyword " smart mobile phone ".After user clicks " trendy ", show the link not comprising one group of Assisted Keyword of " trendy " selected by appraisal size at region D31, such as " brand, 4G, large-size screen monitors, sales promotion "; The Search Results relevant with " trendy " to " smart mobile phone " and bid advertisement is shown at region D32.
