Fig. 1 shows the flow chart of the service providing method according to one embodiment of the disclosure.As shown in Figure 1, the service
Providing method includes the following steps S101-S103：
In step S101, the service total amount according to needed for active user's attribute information estimates the active user；
In step s 102, the corresponding different services point of different characteristic tag service set are determined according to the service total amount
Amount；Wherein, each feature tag set of service includes one or more services with same characteristic features label；And it is described not
It is less than or equal to the service total amount with the sum of service component；
In step s 103, according to the solution annual reporting law of knapsack problem, service feedback attribute and the service component from institute
It states in different characteristic tag service set and determines one or more services；
In step S104, the one or more services determined are supplied to user.
In the present embodiment, service can be the visible object that user is obtained by purchase or other modes from third party
Or intangible labor etc..Such as：The vehicle maintenance service that 4S shops provide, the house decoration service that house ornamentation company provides, food and drink clothes
Vegetable service that business provider provides etc..Service total amount can be can be to number, time, expense that service is quantified etc..
Active user can be that purchase or other modes is needed to obtain the user of service, and the attribute information of active user can be including current
User uses or bought the historical record serviced, gender, the hobby of active user etc..
In the present embodiment, it can be set according to the type of service and the user's crowd characteristic for liking the service etc. for service
Put feature tag.It can be referred to as service portrait, similar user draws a portrait, and can also set representation data to service, it is set
Put individualized feature label.For example, for food and drink, it is very crucial for how understanding a course, because this is to influence energy
Enough it is the key of the good personalized recommendation vegetable of user；For example recommend to recommend meat and vegetables collocation during set meal, that just needs to identify dish
The meat and vegetables feature of product；And the suitable time of vegetable is also more crucial, such as the demand that Various Seasonal may be to sheep soup is different,
And afternoon tea and dinner, breakfast are also to have very big difference in time.These are construed as portraying for vegetable, referred to as vegetable
Portrait；It can be divided into for the label portrayed：Foundation characteristic label, statistical nature label and assemblage characteristic label.As major ingredient, auxiliary
Material may be considered foundation characteristic label；And the favorable rating of some users may be considered statistical nature label, in different seasons
Fast-selling vegetable under section, different periods is the assemblage characteristic label for being combined and being formed according to historical data.The feature of service
Label can pass through the foundation characteristic label of the determining services such as feature extraction, cleaning, the processing of characteristic value namely service institute itself
With some features；The statistical nature label that can also be serviced later by Feature Selection, then pass through feature group
Close and dimension-reduction treatment after the assemblage characteristic label that can be serviced, include in the setting up procedure of the feature tag of service but not
It is limited to the processes such as data acquisition, ETL process, data statistic analysis and data mining.
In the present embodiment, by handling service, after the one or more features label serviced, based on difference
Feature tag establish feature tag set of service, each feature tag set includes one or more service, and these are serviced
Feature tag corresponding to this feature tag set, the service in different characteristic tag set there may be intersection, this is because
One service may have multiple feature tags.
When for active user's recommendation service, by active user's attribute estimate can be in tolerance range in active user clothes
Business total amount, the service for being most suitable for active user is chosen from corresponding different characteristic tag set, is supplied to user again later, and
In order to ensure that the sum of amount of service chosen in each feature tag set can also be different characteristic no more than total amount is serviced
Tag set distributes certain service component so that the amount of selected service and corresponding clothes from each feature tag set
Business component matches.For example, active user when ordering, can be determined based on previous dining historical record of active user etc.
The previous visitor's unit price of active user, i.e. pre-capita consumption, for example the time of currently ordering is 12：10, then can select yesterday or
Nearest three days 12：00-12：10 reference as visitor's unit price；Then according to currently having dinner number and objective unit price is estimated
This overall consumption amount of money having dinner；It is distributed centainly further according to vegetable set of the set meal collocation mode for different characteristic label later
Spending amount so that the amount of money summation assigned by multiple feature tag vegetable set corresponding to a set meal collocation mode is not
More than the overall consumption amount of money.In this way, select corresponding vegetable, after being arranged in pairs or groups, obtain from each feature tag vegetable set again
Vegetable collocation set meal total price control within the overall consumption amount of money.Such as estimate active user this time have dinner consumption total amount be
100 yuan, if vegetable is set to 4, then meat and vegetables collocation is 1：If 1, then 2 vegetables can be distributed respectively, it is 50 yuan average, if
Cold and hot collocation, and 1：If 3, then cold is 1, and Hot dishes is 3, the former amount of money is 25, and the latter's amount of money is 75 yuan.
After the service component for determining each feature tag set, can the solution annual reporting law based on knapsack problem, from
Optimal one or more services are selected in feature tag set, and the quality serviced can be based on service feedback attribute come really
It is fixed.Service feedback attribute can be the quantization score obtained by user for the feedback information of the service, which can
For the quality of reflection service, quantization score is higher, illustrates that service is more excellent, and quantization score is lower, illustrates that service is poorer.Example
Such as, for vegetable service, can feedback attributes be determined to the marking of the vegetable, pageview, purchase volume etc. by user.
Knapsack problem (Knapsack problem) is a kind of np complete problem of Combinatorial Optimization.Problem can be described as：
One group of article is given, each article has the weight and price of oneself, and in the total weight of restriction, how we select, ability
So that the total price highest of article.It, can be by the corresponding service component of a feature tag set of service to mark in the present embodiment
For the total weight in knapsack problem, the amount that is each serviced in feature tag set of service is to being designated as the weight of the article in knapsack problem
Amount, service feedback attribute is to item price in mark knapsack problem, in the case of no more than total weight, that is, service component, from spy
It levies and one or more services is selected in tag service set so that the service feedback category of selected one or more services out
Property the sum of i.e. article total price highest.The embodiment of the present disclosure by knapsack problem, is no more than current spy meeting restrictive condition
In the case of levying the corresponding service component of tag service set, optimal one or more clothes are selected from a set of service
Business, and the optimal service selected in all selected feature tag set of service is supplied to active user so that
It services in total amount limited range, best service is provided for active user.For example, in the house that house ornamentation system platform provides
In finishing service, can one or more finishing Services Compositions be provided to the user based on the service total price range that user can bear,
Cause total price not in the case of over range, user is given to recommend a variety of Services Compositions that disclosure satisfy that user demand.For another example user
When ordering on meal ordering system platform, can one kind of multiple dishes be recommended for user based on the total price range that user can bear
Set meal combination is savored, is selected for user.It is, of course, understood that the above-mentioned service providing method that the embodiment of the present disclosure provides can
To be applied to any required provide to the user according to the demand of user in the electric business system platform of one or more service packages.
In an optional realization method of the present embodiment, the step S101 is that is, pre- according to active user's attribute information
The step of estimating the service total amount needed for the active user, further comprises following steps：
Institute is determined according to the historical record of the active user and the service object's number obtained from the active user
State service total amount.
It, can be according to the historical record using service before active user and active user in the optional realization method
This time object number of required service, estimates service total amount.Namely pass through the consumer record of active user and this consumption
The number of service estimates the service total amount that this may consume and/or service total quantity etc..It is for example, aobvious according to previous record
Show, pre-capita consumption when active user eats is at 50 yuan or so, and this obtains number of having dinner as 4 people from active user, then may be used
It can be for 200 yuan or so with the total amount for estimating this time dining；So system can be to recommend total price as 200 yuan or so for user
Vegetable.Service object's number can be inputted by active user.Service total amount can service total quantity or service total cost,
It can also be the combination of both quantity of service and service fee.
In an optional realization method of the present embodiment, the step S102 is determined not according to the service total amount
With feature tag set of service the step of corresponding difference service component, further comprise following steps：
Determine the different service components of the corresponding different characteristic tag service set of preset service arranging scheme.
In the optional realization method, service arranging scheme can be preset, by the service of multiple and different types
It carries out collocation and forms a set of service that disclosure satisfy that user's use demand.For example, for room sercive, service arranging scheme can be with
It is vegetable collocation set meal scheme, such as meat and vegetables is arranged in pairs or groups, cold and hot collocation.Different service arranging schemes, is corresponding with different features
Tag service set.Such as two vegetable set of the meat and vegetables collocation character pair label for meat dish and vegetable dish, cold and hot collocation correspond to
Feature tag is two vegetable set of cold dish and Hot dishes.So for each arranging scheme, corresponding all feature tags
The sum of service component of set identified service total amount before being equal to.That is, system is according to any one arranging scheme
The synthesis of the amount of selected one or more services out does not exceed the service total amount of estimated active user.In this way,
May finally be the Services Composition under a variety of arranging schemes of user's recommendation so that user can therefrom select best a set of service
Combination.
In an optional realization method of the present embodiment, the step S103, i.e., according to the solution annual reporting law of knapsack problem
With service feedback attributes and the service component one or more clothes are determined from the different characteristic tag service set
The step of business, further comprises following steps：
For the corresponding any feature tag service set of same service arranging scheme, using the solution of same knapsack problem
Algorithm and same service feedback attribute determine one or more services；Wherein, it is determined from a feature tag set of service
The sum of amount of one or more services gone out is no more than the corresponding service component of the feature tag set of service.
In the optional realization method, a kind of service arranging scheme may correspond to one or more features tag service collection
It closes, and a feature tag set of service includes one or more services, and the corresponding service of this feature tag service set
The fixed situation of component can select total amount no more than this feature based on knapsack problem from this feature tag service set
One or more optimal services of tag service set corresponding with service component, and the quality serviced can be based on service feedback attribute
To determine.The solution annual reporting law of knapsack problem can include a variety of, such as Dynamic Programming, greedy algorithm, genetic algorithm etc., and different
The answer that is likely to be obtained of solution annual reporting law it is different, therefore the solution annual reporting law different in the case where other preconditions are constant
Also different Services Compositions can be obtained；In addition, service feedback attribute to mark knapsack problem in Item Value, in service feedback category
Property different (such as scoring, pageview or amounts of ordering of vegetable etc.) in the case of Item Value it is different, then at other
In the case that part is constant, using different service feedback attributes when can also obtain different Services Compositions.
In an optional realization method of the present embodiment, as shown in Fig. 2, the step S104, i.e., it will be determined
The step of one or more services are supplied to user, further comprises the steps S201-S202：
It in step s 201, will be same from correspondence using the solution annual reporting law of same knapsack problem and same service feedback attribute
The one or more services determined in the different characteristic tag service set of preset service arranging scheme are determined as a clothes
Business combination；
In step S202, it will be determined using the solution annual reporting law of different knapsack problems or different service feedback attributes multiple
Services Composition is supplied to the active user.
In the optional realization method, for a kind of service arranging scheme, using the solution final accounts of identical knapsack problem
Method and identical service feedback attribute obtained from multiple feature tag set of service corresponding with the service arranging scheme one
A or multiple services form a Services Composition of the corresponding service arranging scheme, and by changing the solution annual reporting law of knapsack problem
Or service feedback attribute can also must correspond to other Services Compositions of the service arranging scheme；So arrange in pairs or groups for a variety of services
Scheme can obtain more Services Compositions according to this, these Services Compositions be recommended active user, active user can be from this
A desired Services Composition is selected in a little Services Compositions, the time that user selects service can be saved in this way, and due to being root
It is combined according to the good service selected by user's self-demand out, better experience can be brought to user.In addition, user can be with
Selected Services Composition is adjusted according to itself hobby, obtains best Services Composition.
In one embodiment, in all feature tag set obtained according to a variety of knapsack algorithms or service feedback information
The multiple services in family after, these one or more set of service can also be got up, determine the number that each service occurs,
From the up to minimum total amount that filters out of occurrence number user is supplied to no more than the one or more services for servicing total amount.Screening
Rule can be that the secondary solution of solution annual reporting law that is random or reusing knapsack problem obtains result.
In an optional realization method of the present embodiment, as shown in figure 3, service providing method is further comprising the steps of：
In step S301, demand information of the active user to service is obtained；
In step s 302, screening is obtained by the different characteristic tag service set according to the demand information.

It puts including estimating module 401, the first determining module 402, the second determining module 403 and third determining module 404：
Module 401 is estimated, the service being configured as according to needed for active user's attribute information estimates the active user is total
Amount；
First determining module 402 is configured as determining that different characteristic tag service set corresponds to according to the service total amount
Different service components；Wherein, each feature tag set of service, which includes one or more, has same characteristic features label
Service；And the sum of described different service components are less than or equal to the service total amount；
Second determining module 403 is configured as according to the solution annual reporting law of knapsack problem, service feedback attribute and the clothes
Business component determines one or more services from the different characteristic tag service set；
Third determining module 404, the one or more services for being configured as to be determined are supplied to the active user.
In the present embodiment, service can be the visible object that user is obtained by purchase or other modes from third party
Or intangible labor etc..Such as：The vehicle maintenance service that 4S shops provide, the house decoration service that house ornamentation company provides, food and drink clothes
Vegetable that business provider provides etc..Service total amount can be can be to number, time, expense that service is quantified etc..Currently
User can be that purchase or other modes is needed to obtain the user of service, and the attribute information of active user can include active user
Using or bought the historical record of service, gender, the hobby etc. of active user.
In one embodiment, service can be vegetable；It can be vegetable price or vegetable quantity to service total amount；Or service
Total amount can be vegetable price and vegetable quantity.
In the present embodiment, it can be set according to the type of service and the user's crowd characteristic for liking the service etc. for service
Put feature tag.It can be referred to as service portrait, similar user draws a portrait, and can also set representation data to service, it is set
Put individualized feature label.For example, for food and drink, it is very crucial for how understanding a course, because this is to influence energy
Enough it is the key of the good personalized recommendation vegetable of user；For example recommend to recommend meat and vegetables collocation during set meal, that just needs to identify dish
The meat and vegetables feature of product；And the suitable time of vegetable is also more crucial, such as the demand that Various Seasonal may be to sheep soup is different,
And afternoon tea and dinner, breakfast are also to have very big difference in time.These are construed as portraying for vegetable, referred to as vegetable
Portrait；It can be divided into for the label portrayed：Foundation characteristic label, statistical nature label and assemblage characteristic label.As major ingredient, auxiliary
Material may be considered foundation characteristic label；And the favorable rating of some users may be considered statistical nature label, in different seasons
Fast-selling vegetable under section, different periods is the assemblage characteristic label for being combined and being formed according to historical data.The feature of service
Label can pass through the foundation characteristic label of the determining services such as feature extraction, cleaning, the processing of characteristic value namely service institute itself

In the present embodiment, by handling service, after the one or more features label serviced, based on difference
Feature tag establish feature tag set of service, each feature tag set includes one or more service, and these are serviced
Feature tag corresponding to this feature tag set, the service in different characteristic tag set there may be intersection, this is because
One service may have multiple feature tags.
When for active user's recommendation service, by active user's attribute estimate can be in tolerance range in active user clothes
Business total amount, the service for being most suitable for active user is chosen from corresponding different characteristic tag set, is supplied to user again later, and
In order to ensure that the sum of amount of service chosen in each feature tag set can also be different characteristic no more than total amount is serviced
Tag set distributes certain service component so that the amount of selected service and corresponding clothes from each feature tag set
Business component matches.For example, active user when ordering, can be determined based on previous dining historical record of active user etc.
The previous visitor's unit price of active user, i.e. pre-capita consumption, for example the time of currently ordering is 12：10, then can select yesterday or
Nearest three days 12：00-12：10 reference as visitor's unit price；Then according to currently having dinner number and objective unit price is estimated
This overall consumption amount of money having dinner；It is distributed centainly further according to vegetable set of the set meal collocation mode for different characteristic label later
Spending amount so that the amount of money summation assigned by multiple feature tag vegetable set corresponding to a set meal collocation mode is not
More than the overall consumption amount of money.In this way, select corresponding vegetable, after being arranged in pairs or groups, obtain from each feature tag vegetable set again
Vegetable collocation set meal total price control within the overall consumption amount of money.Such as estimate active user this time have dinner consumption total amount be
100 yuan, if vegetable is set to 4, then meat and vegetables collocation is 1：If 1, then 2 vegetables can be distributed respectively, it is 50 yuan average, if
Cold and hot collocation, and 1：If 3, then cold is 1, and Hot dishes is 3, the former amount of money is 25, and the latter's amount of money is 75 yuan.
After the service component for determining each feature tag set, can the solution annual reporting law based on knapsack problem, from
Optimal one or more services are selected in feature tag set, and the quality serviced can be based on service feedback attribute come really
It is fixed.Service feedback attribute can be the quantization score obtained by user for the feedback information of the service, which can
For the quality of reflection service, quantization score is higher, illustrates that service is more excellent, and quantization score is lower, illustrates that service is poorer.Example
Such as, for vegetable service, can feedback attributes be determined to the marking of the vegetable, pageview, purchase volume etc. by user.
Knapsack problem (Knapsack problem) is a kind of np complete problem of Combinatorial Optimization.Problem can be described as：
One group of article is given, each article has the weight and price of oneself, and in the total weight of restriction, how we select, ability
So that the total price highest of article.It, can be by the corresponding service component of a feature tag set of service to mark in the present embodiment
For the total weight in knapsack problem, the amount that is each serviced in feature tag set of service is to being designated as the weight of the article in knapsack problem
Amount, service feedback attribute is to item price in mark knapsack problem, in the case of no more than total weight, that is, service component, from spy
It levies and one or more services is selected in tag service set so that the service feedback category of selected one or more services out
Property the sum of i.e. article total price highest.The embodiment of the present disclosure by knapsack problem, is no more than current spy meeting restrictive condition
