The present invention proposes a kind of searching method, for providing the user the searching order result of personalization, embodiment bag
Include following steps：
S10：The request of the retrieval main broadcaster comprising search key that user sends is obtained, pass is retrieved according to search key
Main broadcaster's list of connection；
S20：Obtain every main broadcaster and the matching degree M of search key in main broadcaster's list；
S30：Viewing record and pay records of the user to every main broadcaster in main broadcaster's list are obtained, according to user to every master
The viewing record and pay records broadcast, calculate satisfaction S of the user to every main broadcaster；
S40：The score value V of every main broadcaster is calculated according to matching degree M and satisfaction S；
S50：Retrieval main broadcaster's result of user is obtained using score value V.
Each step in the embodiment is detailed below：
Step S10：The request of the retrieval main broadcaster comprising search key that user sends is obtained, is retrieved according to search key
Go out main broadcaster's list of association；
Obtain user retrieval main broadcaster request can by video player, live platform, can play video webpage etc. it is more
Kind approach obtains；The retrieval main broadcaster request of user can by word or phonetic entry, when it is phonetic entry to retrieve main broadcaster's request,
Corresponding word can be converted speech into, after word corresponding to user's confirmation or modification, then obtains the request.In the step
In, the historical search keyword of user or popular search keyword can also be pushed to the inputting interface of user, to prompt or add
The input of fast user.The information of main broadcaster relates generally to the pet name of main broadcaster, the introduction of main broadcaster, channel cornet, channel introduction, game name
Claim, game is introduced, the affiliated category belonging to programme televised live, the label information etc. of main broadcaster or channel.During retrieval, by search key
Matched with all information of main broadcaster；The part that search key may be set in all information with main broadcaster matches completely,
Also it may be set to fuzzy matching.Search key can be a keyword or multiple keywords, can also for a keyword or
Multiple keywords.According to the matching result of search key, main broadcaster's list of association is retrieved.
Step S20：Obtain every main broadcaster and the matching degree M of search key in main broadcaster's list；
Information matches position that can be according to every main broadcaster in search key and main broadcaster's list or matching degree, are matched
M concrete numerical value is spent, such as search key matches with the accurate information of main broadcaster, then matching degree M numerical value is higher, fuzzy matching
Then matching degree M numerical value is relatively low；Or the pet name of search key and main broadcaster, the information labels of main broadcaster, the identity id number of main broadcaster
Matched Deng directional information, then matching degree M numerical value is higher, and content that the classification, main broadcaster with main broadcaster play etc. is non-to be pointed to specifically
The information matches of main broadcaster, then matching degree M numerical value is relatively low.The concrete numerical value can be by searching default matching degree M numerical tabular
Obtain, can also be calculated and obtained by default formula.Matching degree M in the step relates generally to search key and main broadcaster's information
Matching precision, it is unrelated with the individuation data of user；More accurately to position user's request, it is necessary to reference to the individual character of user
Change data, therefore present invention additionally comprises following steps：
S30：Viewing record and pay records of the user to every main broadcaster in main broadcaster's list are obtained, according to user to every master
The viewing record and pay records broadcast, calculate satisfaction S of the user to every main broadcaster；
Whether user likes watching the programme televised live of certain main broadcaster, generally not quantifiable emotional factor, but to use
Family quickly obtains the main broadcaster liked, it is necessary to is quantified not quantifiable emotional factor by the behavioral parameters of user.At this
In invention, user can count to the satisfaction of every main broadcaster according to user to the viewing record and pay records of every main broadcaster
Calculate；Described viewing record and pay records specifically may include：Total access time of platform, Yong Huguan where user accesses main broadcaster
Total time, the quantity of all main broadcaster's programs accessed of program are seen live, user accesses the total degree and total time, list of certain main broadcaster
The duration of secondary access, recommend or share to other people number, the total amount of payment of the user to all main broadcasters and total degree, user
The parameters such as payment amount and payment number to certain main broadcaster.For example, the duration that certain main broadcaster can be watched by calculating user accounts for
The user watches the ratio of all programme televised live durations, calculates user and watches the number of certain main broadcaster and accounts for and access the live platform
The duration that the ratio of total degree, calculating user's single watch certain main broadcaster exceedes the number of preset time, certain main broadcaster is paid
The methods of expense number accounts for the ratio ... of payment number to all main broadcasters obtains satisfaction S of the user to every main broadcaster, or general
Each computational methods carry out mathematical combination above, or combination other parameters and computational methods obtain satisfaction of the user to every main broadcaster
Spend S value.Can concrete example it is as follows：User watches the master according to the user to the satisfaction S of certain main broadcaster within the proximal segment time
The duration broadcast determines：If user watched the accumulation duration of the main broadcaster more than 10 hours in nearest one month, user is to the master
The satisfaction S=5 broadcast, if user watched the accumulation duration of the main broadcaster more than 5 hours in nearest one month, user is to the master
The satisfaction S=4 broadcast, if user watched the accumulation duration of the main broadcaster more than 2 hours in nearest one month, user is to the master
The satisfaction S=3 ... broadcast the like, it can obtain the concrete numerical value of the satisfaction S of every main broadcaster in main broadcaster's list.
According to the complexity of influence of the customer parameter in practical application to retrieval result and calculating, the present invention is preferably
Determine satisfaction S numerical value with pay records to the viewing record of every main broadcaster according to user.
Step S20 and step S30 of the present invention order is commutative, i.e. matching degree M and satisfaction S acquisition order
Adjustable, its order has no effect on score value V calculating.
S40：The score value V of every main broadcaster is calculated according to matching degree M and satisfaction S；
Obtain in retrieval result after the matching degree M and satisfaction S of every main broadcaster, further according to default Rating Model, difference
Calculate the score value V of every main broadcaster in main broadcaster's list.Score value V can be with the satisfaction S in Rating Model and matching degree M in just
Than V=k can be abbreviated as1S+k2F+k3, or V=k4SF, or wherein K1、K2、K3、k4Be constant or with the satisfaction S of user and
Other parameters unrelated matching degree M.
S50：Retrieval main broadcaster's result of user is obtained using score value V.
Score value V big I reflects that user to the desirability of main broadcaster, can arrange main broadcaster according to score value V numerical value
Main broadcaster in table carries out descending sort, and the main broadcaster for best suiting user's request is arranged in the front end of list.Also can be by score value V
It is combined and is ranked up with other parameters, such as number of subscribers of maximum on-line people or main broadcaster by score value V and main broadcaster etc.
Parameter, which is combined, to be ranked up.
When the present invention can be applied not only to user and scan for, by the matching degree of search key and main broadcaster is high and user
The high main broadcaster of viewing satisfaction is arranged in position forward in retrieval result list, applies also for user and accesses live put down again
During platform, system actively pushes the scene of main broadcaster's sequence to user, i.e.,：System is recorded by the search of user's history, viewing records
Score value V calculated the main broadcaster of active push with pay records, and according to score value V size to being pushed to main broadcaster's sequence of user
Row are ranked up, and make user without by search key or other lookup associative operations, you can get currently emerging with user
Main broadcaster's sequence that interest is identical.Being exposed for user has strong interest but the sticky main broadcaster being not sufficiently stable, and energy of the invention is fast
Speed is shown or is pushed to user, reduces the process that user finds.
The present invention also proposes a kind of embodiment for obtaining matching degree M concrete numerical values, every master in acquisition main broadcaster's list
The matching degree M with search key is broadcast, including：
According to the information matches position of every main broadcaster in search key and main broadcaster's list, default matching degree M, institute are obtained
State matching degree M and meet following condition：
If the search key matches with the pet name of main broadcaster, M=4；
If the search key matches with the channel cornet of main broadcaster, M=3；
If the search key matches with the game name of main broadcaster, M=2；
If the search key matches with the affiliated category of main broadcaster, M=1.
If user is interested in a certain main broadcaster, searching for directive property is typically carried out with the channel cornet of main broadcaster's pet name or main broadcaster
Rope, there is the predeterminable higher matching degree of the search key of pointing clearly to property to such, so that user searches sensing as early as possible
Main broadcaster.If user is directed to topic or content interested using search key search, for example, for certain specific game name or
It is the live categories such as similar true man's tourism show, then does not point to certain specific main broadcaster；If therefore user input search key with
Information match beyond the pet name or channel cornet of main broadcaster, then preset relatively low matching degree numerical value for it.
The present invention also proposes a kind of embodiment for the satisfaction S for calculating every main broadcaster, and the acquisition user is to main broadcaster's list
In every main broadcaster viewing record and pay records, viewing record and pay records according to user to every main broadcaster, calculate use
Family to the satisfaction S of every main broadcaster, including：
Obtain user individuation data, the individuation data include to each main broadcaster user in main broadcaster's list whether
There are viewing number b, the payment number c to main broadcaster that viewing historical record a, the duration of viewing main broadcaster meet preset duration；
Satisfaction S of the user to every main broadcaster is calculated, satisfaction S meets following condition：
S=a+b+c,
Wherein, there is viewing historical record to the main broadcaster user, then a=1；Historical record is not watched to the main broadcaster user,
Then a=0.
The embodiment there may be quantified dimension of the parameter of difference as satisfaction S using most of user, in simplification
The interest difference of user is distinguished while calculating process.The access times (VisitView, VV number of abbreviation) of user are all visits
Visitor accesses video resource or website, the access times of programme televised live, be video resource or webpage, programme televised live important parameter it
One.Same visitor may repeatedly access same video resource or website, enter video resource or website to final plant closure from visitor
Video resource or website, it is calculated as 1 access.If visitor does not have Xin Kai and refresh page in preset duration, or visitor closes
Browser, then be calculated as this access and terminate.Judge level of interest of the user to a certain position main broadcaster, refer to its history
Watch number (or VV number) and pay number, in general, to certain main broadcaster watch often, submitting present or virtual wealth
The quantity of production is more, then the satisfaction that represent user to the main broadcaster is higher.To further determine that the satisfaction of user, user
The duration (such as number that user continuously watches 5 minutes, referred to as 5 minutes VV numbers) and important references factor of single viewing main broadcaster
One of, therefore in the present embodiment, the duration that user is watched to main broadcaster meets the viewing number b of preset duration, the payment to main broadcaster
Important accumu-late parameters of the number c as satisfaction S.Meanwhile user is when searching for, if match main broadcaster that user once watched and
The main broadcaster never watched, then that more likely point to is the main broadcaster once watched, but watches and be not directly directed to user couple
The satisfaction of the main broadcaster, therefore in main broadcaster's result is retrieved, whether should be taken into account user to watch caused by the main broadcaster influences, and
Suitable numerical value is set according to the size of its influence.
In the present embodiment, to each main broadcaster in main broadcaster's list, whether user has viewing historical record a Dynamic gene
Value is 1, i.e., user has viewing historical record to the main broadcaster user, then a=1；Historical record is not watched to the main broadcaster user,
Then a=0；The duration for whether having viewing historical record a and viewing main broadcaster to each main broadcaster user is met to the sight of preset duration again
See that number b, the payment number c to main broadcaster sum, obtain satisfaction S numerical value.For example, if user is made with " seeking survival danger spot "
For search key, certain main broadcaster X is searched out；According to the individuation data of the user, it once watched the main broadcaster X, then a=1；And
In the history access record of user, the access time for having 4 times exceedes default duration 5 minutes (i.e. 5 minutes VV numbers), then b=
4；User once had 2 times gave present to the main broadcaster, then c=2；To sum up, S=1+4+2=7.According to the computation model, viewing
The duration of main broadcaster meets that the viewing number b (the VV numbers for meeting preset duration) of preset duration numerical value is higher, main broadcaster is paid
Take that number c numerical value is higher, satisfaction S numerical value is bigger, and then score value V is bigger, should in main broadcaster's result is retrieved to reach
The sequence of main broadcaster is more forward.
For programme televised live, the payment number to main broadcaster can be embodied in sends virtual present to live main broadcaster
Or virtual coin, or carry out beating reward etc. in other forms.
In this embodiment, the satisfaction S of user not only whether have with user viewing historical record it is associated, also and user
The duration of viewing main broadcaster meets that the viewing number of preset duration and the payment number to main broadcaster are associated；And according to the important of parameter
Property, parameter is set to different weights, further optimizes satisfaction S value, and then score value V is optimized, so that inspection
Sequence in rope main broadcaster's result is more bonded user's request.
The present invention also proposes a kind of embodiment for the specific method for calculating score value V, described according to matching degree M and satisfaction
S calculates the score value V of every main broadcaster；Including：
Score value V is calculated according to default Rating Model, the Rating Model includes equation below：
Wherein, K is adjustment parameter.
Due to the quantization parameter that matching degree M and satisfaction S is different dimensions, and the numerical value calculated is larger, in this implementation
Matching degree M and satisfaction S reference standardizations are subjected to numerical value processing in the computation model of example, to eliminate dimension and optimization to scoring
Value V scope, i.e. V=adjustment parameters * (S ' after matching degree M '+numerical value processing after the processing of 1+ numerical value).In the present embodiment,
Standardization with degree M can be reduced to：The matching degree of standardizationBecause score value V can enter
One step is related to other parameters, therefore adjustment parameter K is preset in calculation formula, therefore final score value
In Rating Model, satisfaction S value can be further limited according to the concrete mode for the processing that quantizes；Such as in this scoring mould
In type, if satisfaction S value more than 99, S=100, i.e., satisfaction S maximum occurrences are 100, to prevent there are score value V mistakes
The abnormal conditions such as big.
The search results ranking of user is also closely related with the search key of user, therefore present invention further propose that is related to
The historical search index F of user embodiment, it is specially：The historical search that the individuation data includes search key refers to
Number F, historical search index F meet following condition：
The nearest search date+1 of D=current dates-search key, N are crucial using search in preset number of days
The searching times of word；
The adjustment parameter
I.e.：Score value
In this embodiment, the historical search index F of user according to user in the recent period with regard to a certain search key search
Number determines, if for example, user is used as search key with " ob ", nearest 30 interior use search keys 11 times, then N=
11；Current date is 2017.6.24 days, and the nearest search date of search key is 2017.6.24 days, then D=2017.6.24-
2017.6.24+1=1；The historical search index of the search keyAdjustment parameter
If user can be found in the individuation data of user inputted certain specific search key in nearly 50 days,
The number in nearest 30 days is then taken as searching times N.In this embodiment, can further preset, if user is in 30 days
Searching times are more than 29 times, then N=30, i.e., maximum search number of the user in 30 days is 30, to prevent adjustment parameter K unexpected
Increase occurs abnormal.Certain each numerical value also can separately be preset as the case may be, and be not limited to described concrete numerical value.
It is otherwise 0+5 if the satisfaction S=in the present embodiment has the main broadcaster watched to be scored at 1 according to previous embodiment
Minute vv numbers+payment number, historical search index × (matching degree+numerical value after numerical value processing after the processing of score value V=numerical value
Satisfaction after processing).If the search key " ob " and the pet name of certain main broadcaster of user's input match, the matching of the acquisition
Spend M=4；If according to the individuation data of the user of acquisition, the user has viewing historical record to the main broadcaster user, then a=
1；The duration of viewing main broadcaster meets preset duration viewing number b=5, the payment number c=0 to main broadcaster of 5 minutes, then satisfaction
S=1+5+0=6.
According to above calculation formula, every main broadcaster in main broadcaster's list obtained by the search key of user can be calculated successively
Score value, therefore the present invention also propose a kind of embodiment being ranked up according to score value to the main broadcaster in main broadcaster's list：It is described
Retrieval main broadcaster's result of user is worth to using scoring, including：
According to score value V from high to low, the main broadcaster in main broadcaster's list is ranked up, forms personalized search sequence knot

In terms of personalized search ranking results, although main broadcaster " Jia Ke tigers Dian tiger god (main broadcaster UID=ayyuid=
304582356) it is highest " to watch number, but total score only arranges the 7th.According to search behavior it can be found that nearest one of user
Searched only for 1 time in month, and the last search date is before two weeks, illustrate user although watch the main broadcaster number it is most,
But it is not that the main broadcaster is searched by search key, it is likely that user has subscribed to the main broadcaster, or has been the loyalty of main broadcaster
Real bean vermicelli, there are other channels for being quickly found out the main broadcaster, it is not necessary to the main broadcaster is mainly recommended by search key, therefore
The model of the present invention can reach expected purpose.
In the preferred embodiment, for convenience understand, the step by the acquisition of parameter or calculate with go from the simple to the complex for
Sequence；In actual applications, the order between each step is adjustable, you can first obtains matching degree M, then calculates satisfaction S and go through
History searchable index F, or satisfaction S is first calculated, then matching degree M and historical search index F are obtained, and it is other various possible suitable
Sequence.And wherein matching degree M value can be set as the case may be, 5 minutes VV numbers can also select 10 as the case may be
Minute VV numbers or other numbers, and it is not limited to the concrete numerical value in embodiment.
, can be same by the highest of main broadcaster if score value V identical situations occurs in the main broadcaster of two or more in actually calculating
When the arrangement of online number (the pcu avg_game_pcu in table 2) descending, or arranged according to the current popularity value descending of main broadcaster,
Or the game temperature descending arrangement according to main broadcaster (game temperature can determine according to the current online number or viewing time of game).

Amount can be according to the highest parameter setting such as online number, currently viewing number, such as settable when the highest of main broadcaster simultaneously of main broadcaster
Online number reaches 1000 and can just entered in the preferential position of category simultaneously, if in main broadcaster's list of certain retrieval, only two main broadcasters
Highest online number reaches 1000 simultaneously, then it is only selected two；Or it is arranged to currently viewing number and reaches 500 that product can be entered
The preferential position of class, in main broadcaster's list of certain retrieval, the currently viewing number for having five main broadcasters reaches 500, then is selected in five main broadcasters
To the preferential position of category.Also fixed qty, such as five or by the preferential position of category are arranged to, then from main broadcaster's list of retrieval, according to
The main broadcaster of secondary determination score value V five different categories of highest is arranged in the preferential position of category；If the score value V of main broadcaster is identical,
Then it is selected in highest online number highest main broadcaster simultaneously.
It is described successively determine can be specially：Since first main broadcaster of secondary ranking results, the main broadcaster institute is judged successively
Whether the category of category is the category occurred for the first time, if it is, the preferential position of category is loaded on, if it is not, then being not loaded with, directly
It is booked to the preferential position of category.This method can ensure that the main broadcaster of each category has and only one, and be score value in this category
Highest (if score value V is identical, highest while online number highest).
