For ease of understanding the present invention program, Bayesian network of the present invention is simply introduced first below.
Bayesian network is a kind of probability net, and it is the graphical network based on probability inference, and Bayesian formula is thenIt is the basis of this probability net.Bayesian network is the mathematical modeling based on probability inference, and so-called probability inference is exactly to pass throughThe information of some variables obtains the process of other probabilistic informations, Bayesian network (Bayesian based on probability inferenceNetwork) proposed to solve the problems, such as ambiguity and imperfection, it is for solving complex device uncertainty and closingFailure caused by connection property has very big advantage, and extensive use is obtained in multiple fields.It is a kind of simulation mankind inference's processIn causal Uncertainty Management model, refer to Fig. 4, its network topology structure is a directed acyclic graph (DAG), itsIn each one stochastic variable of node on behalf, the side between node represents and directly relies on relation between variable.
In Fig. 4, event a and event b are separate, in event a probability of happening P (a), event b probability of happening P (b), eventPremise known to event c probability of happening P under the premise of event c probability of happening P (c | a), event b occur under the premise of a occurs (c | b)Under, can be with predicted events c probability of happening.

P (c | a)=P (a | c) * P (c)/p (a)；
P (b | a)=P (a | b) * P (b)/p (a).
Based on the simple introduction above with respect to Bayesian network, start to illustrate the present invention program below.
The concept of usage scenario information is proposed in the present invention, usage scenario information is primarily referred to as the environment residing for mobile terminalState, for example, current time, place, network environment etc..It is easily understood that the difference of usage scenario, user may useApplication it is different, for example, in non-Wi-Fi environment, user is relatively low using the possibility of video playback class software, when at home,User is larger using the possibility of the applications such as wechat, Taobao and microblogging.
In embodiments of the present invention, when triggering background application cleaning, current usage scenario letter is got firstBreath, for example, getting current usage scenario information for " network environment is Wi-Fi environment ".Wherein, for triggering background applicationThe triggering mode of program cleaning, can manually be triggered by user, also can actively be triggered by mobile terminal, the present invention does not do specific limitSystem, is specifically configured, for example, as shown in figure 5, user can pass through mobile terminal according to actual needs by those skilled in the art" cleaning " control is provided, triggering carries out background application cleaning；In another example, mobile terminal reaches in the quantity of background applicationDuring to predetermined threshold value, triggering carries out background application cleaning.
In addition, the present invention also prestore that each application program on mobile terminal is used by a user under each usage scenario it is generalRate, and the probability that types of applications program is used by a user under each usage scenario.While usage scenario information is obtained, alsoGet under each usage scenario prestored that each application program is used simultaneously first uses each under probability, and each usage scenarioWhat class application program was used second uses probability.It is easily understood that each application program has its characteristic attribute value, it is such as excellentExtremely, iqiyi.com, Tengxun's video etc. belong to the video playback class application program for expending flow, the possibility used in Wi-Fi environmentProperty is larger；Microblogging, today's tops, Tengxun's news etc. belong to entertain class application program, the possibility used on one's own timeIt is larger；Rub and visit bicycle, ofo etc. and belong to vehicles class application program, the possibility used in traffic point is larger.So as to this hairThe bright characteristic attribute value for application program, is divided into polytype application program, including but do not limit by application program in advanceIn：Video playback class application program, amusement class application program and vehicles class application program etc..
In embodiments of the present invention, a Bayesian network probability calculation model is constructed in advance, for predicting that some is usedFamily starts the probability of some background application, that is to say the probability for predicting that some background application is used.It refer to figure6, it is the structural representation of Bayesian network probability calculation model, as shown in fig. 6, the Bayesian network probability calculation model hypothesisThe probability that some background application is used depends on each application program quilt under the usage scenario of mobile terminal, each usage scenarioFirst used uses under probability and each usage scenario types of applications program is used second to use probability.So as to obtainEach application program is used under to current usage scenario information, each usage scenario first uses probability, and respectively uses fieldTypes of applications program is used under scape second is used after probability, by currently used scene information, it is each first using probability withAnd each second be input in default Bayesian network probability calculation model using probability, each background application is calculated currentWhat usage scenario was used the 3rd uses probability.
In the specific implementation, Bayesian network probability calculation model calculates each background application according to equation below and worked asWhat preceding usage scenario was used the 3rd uses probability：
Score (A)=P (A | S, A ', A ")；
Wherein, Score (A) represent background application " A " used under currently used scene " S " the 3rd use generallyEach application program is used under rate, each usage scenario of A ' expressions first uses probability, and A " represents all kinds of under each usage scenario and answeredSecond used with program uses probability.
The 3rd of each background application is obtained in calculating and uses probability, that is to say that calculating obtains each background application and existedAfter the 3rd use probability that currently used scene is used by a user, it is clear that, the 3rd should using the bigger backstage of probabilityMay be more used by a user with program, then after the cleaning during platform application program, it is necessary to preferentially retain it is larger may be by userThe application program used.In the present embodiment, it is previously provided with the expression larger probability threshold that may be used by a user of application programValue, is designated as predetermined probabilities threshold value, thus after the cleaning platform application program when, can closing the 3rd, to be less than this using probability default generalThe background application of rate threshold value.
Alternatively, in other embodiments, it can be obtained according to the maximum background process number and calculating in real time of mobile terminalEach background application the 3rd use probability, dynamic updates the specific value of predetermined probabilities threshold value, for example, mobile terminalMaximum background process number is 5, after calculating the obtain each background application the 3rd using probability, according to probability from large to smallOrder, be ranked up to the 3rd of each background application the using probability, predetermined probabilities threshold values be updated to sequence the 5thThe 3rd of background application uses probable value.In other words, after the cleaning platform application program when, retain the 3rd use probability highest, the background application with maximum background process number same number.
Further, in the present embodiment, also include before step S10：
First for counting and storing each application program under each usage scenario uses probability.
In the present embodiment probability is used, it is necessary to count obtain first of each application program under each usage scenario in advance.When it is implemented, in the first preset time period, when user uses application program every time (namely certain application program is activatedWhen), the usage scenario information (including current time, place and network environment etc.) of record now, so that it is pre- to obtain firstIf in the period, number of run of each application program under each usage scenario, and the total number of run of each application program, then pinTo a certain application program, number of run of the application program under a usage scenario and the quotient of total number of run are designated asThe application program first uses probability under the usage scenario, by that analogy, obtains each application program quilt under each usage scenarioFirst used uses probability.
Further, in the present embodiment, also include before step S10：
Preset types of applications program under each usage scenario second uses probability.
In the present embodiment, it is necessary first to which each application program on mobile terminal is classified.Specifically, mobile wholeWhen certain application program is downloaded in end from certain in response to user's operation using shop, the download page of the application program is parsed,The label information (i.e. preceding feature property value) of the application program is obtained, the label letter of application program " rub and visit bicycle " is such as gotCease for " bicycle " and " mobike ", the label information for getting application program " youku.com " is " video " and " player ".
Afterwards, each application program is classified according to the label information of each application program got, such as according to " Mo BaiThe label information " bicycle " of bicycle " and " mobike " are classified as vehicles class application program, such as according to the label of " youku.com "Information " video " and " player " are classified as video playback class application program.
It should be noted that when obtaining the label information of application program, multiple label informations may be got simultaneously, andTo not being that each label information can reflect the type of application program in individual label information.Accordingly, it would be desirable to the mark of acquisitionLabel information is pre-processed, and filters out useless label information.For example, getting the label information of application program " serge mile serge mile "" video ", " player " and " Quadratic Finite Element ", it is clear that, " Quadratic Finite Element " is for determining the type of application program " serge mile serge mile " simultaneouslyWithout use, it can filter out and not record, only record " video " and " player ".
After the Type division to each application program is completed, preset types of applications program under each usage scenario second makesWith probability, the reasonable setting of the second use probability has been largely fixed the order of accuarcy of prediction, can be by gathering in advanceFUT user profile confirms rational probable value, for example, default " video playback class application program " is under " Wi-Fi environment "Second is 60% using probability, and preset " shopping class application program " in " in family " second using probability is 80%.
Application management method proposed by the present invention, when platform application program is cleared up on triggering, obtains current use firstEach application program is used under scene information, each usage scenario prestored first uses each under probability, and each usage scenarioWhat class application program was used second uses probability, and currently used scene information, each first then are used into probability and each theTwo are input in default Bayesian network probability calculation model using probability, calculate each background application in currently used fieldWhat scape was used the 3rd uses probability, finally closes the 3rd background application for being less than predetermined probabilities threshold value using probability, makesAfter the cleaning platform application program when, it is contemplated that user user is accustomed to, it is to avoid background application is by the termination of mistake, liftingThe accuracy of application management.
Further, based on first embodiment, the second embodiment of application management method of the present invention is proposed, in the present embodimentIn, it is further comprising the steps of before step S30：
Using the user preference value of each background application prestored, the 3rd of each background application of correspondence amendment usesProbability.
It is easily understood that in real life, user is during using application program, to different application programsDifferent preferences are had, for example, party A-subscriber's preference carries out network social intercourse using QQ, party B-subscriber's preference carries out network using wechatSocial activity etc..Therefore, the present embodiment is on the basis of aforementioned first embodiment, further using the user preference value quantified to calculatingObtain each application program the 3rd is modified using probability, can more accurately express the possibility being used by a user.
In embodiments of the present invention, obtain each background application and the 3rd make what currently used scene was used calculatingAfter probability, first by the user preference value of each background application prestored, each background application of correspondence amendment3rd uses probability.In the specific implementation, using user preference value to the 3rd using probability be modified including：
Choose a background application；
Based on the user preference value for the background application chosen, and default user preference value is with correcting reflecting for probabilityRelation is penetrated, it is determined that the amendment probability corresponding to the background application chosen；
The 3rd of the background application the chosen probability and value for using probability and amendment probability is calculated, by the probability of calculatingWith value probability is used as the revised 3rd；
Continue to choose a background application, until each background application is selected, complete to each background application journeyThe 3rd of sequence uses the amendment of probability.
It should be noted that in the present embodiment, user preference value and the mapping relations of amendment probability are previously provided with, shouldMapping relations are used to describe user preference value to the 3rd influence degree using probability, specifically, user preference value is bigger, to theThree is bigger using the influence degree of probability, and corresponding amendment probability is bigger, and as constraint, those skilled in the art can be according to realityBorder needs to set user preference value with correcting the mapping relations of probability.
For example, amendment probability k=1-1/i, i are user preference value, span is [1,10], be that is to say user preferenceValue is divided into 10 levels.When the user preference value i of certain background application is 10, you can calculating obtains the background application journeyThe amendment probability of sequence is 90%.
It should be noted that when the revised 3rd is more than 1 using probability, will amendment in the embodiment of the present inventionAfterwards it is more than 1 and the 3rd 1 is directly designated as using probability, obtains the 3rd of certain background application for example, calculating and be using probability60%, and it is 50% to determine that it corrects probability according to the user preference value of the background application, the then background application3rd using probability and amendment probability and value be 110%, it is now direct by background application the revised 3rd more than 11 is designated as using probability, in other words, the probability that the background application is used by a user under currently used scene is 100%.
Further, to be repaiied using user preference value to the 3rd of each background application of calculating the using probabilityJust, need head to be accomplished by the user preference value for first obtaining characterizing user preference degree, in the present embodiment, before step S10, also wrapInclude following steps：
Count and store the user preference value of each application program.
In the specific implementation, the user preference value for counting and storing each application program includes：
Count number of run of each application program in preset time period, and the resident duration on foreground；
According to number of run and each self-corresponding weights of resident duration, number of run based on each application program and it is resident whenIt is long, calculate and store the user preference value of each application program.
It is common, if user is higher using the usage frequency of a certain application program, and the application program resident foreground timeIt is longer, then illustrate that the preference of user's application program is higher.Therefore, in the present embodiment, based on application in a period of timeThe number of run of program, and resident foreground duration, build application program user preference value and number of run and it is resident whenLong mapping relations are as follows：
I=x*m+y*n；
Wherein, i represents the user preference value of application program, and x represents number of run of the application program in preset time period(number of run on foreground), m represents the corresponding weights of number of run, and y represents application program in preset time period on foregroundResident duration, n represents the resident corresponding weights of duration, and m, n value are rule of thumb set.
In the specific implementation, in preset time period when user uses application program every time (namely certain application program quiltDuring startup), record the application program and stay the period (initial time and deadline) on foreground, current network conditions information (such asFailed cluster, Wi-Fi networkings, GPRS networkings etc.), current GPS location information (in such as family, place of working), and be to initial valueZero, the operation of the application program is persistently updated, due to being both needed to record the information using App every time, therefore can be with shouldIt is one application data set of each applicating maintenance with entitled Key values are wrapped
Alternatively, preset time period could be arranged to one it is naturally all, that is to say with one naturally week for the cycle, to applyingThe user preference value of program is updated so that it can more accurately reflect preference of the user to application program.
Further, based on first embodiment, the 3rd embodiment of application management method of the present invention is proposed, in the present embodimentIn, before step S10, in addition to：
The operational factor of acquisition system, and meet default background application cleaning condition in the operational factor of acquisitionWhen, triggering background application cleaning.

In the present embodiment, first obtain system operational factor, wherein, the operational factor of acquisition include but is not limited to beSystem power consumption, memory usage and system temperature etc..
After the operational factor of system is got, according to the operational factor of acquisition judge it is current whether meet it is default afterPlatform application program clears up condition, if then triggering carries out background application cleaning.Wherein, background application cleaning condition canIt is configured according to actual needs, the present invention is not particularly limited, for example, for system power dissipation, default background applicationCleaning condition is " system power dissipation is more than or equal to 1500mW "；For memory usage, default background application clears up barPart is " memory usage is more than or equal to 90% "；For system temperature, default background application cleaning condition is " systemTemperature is more than or equal to 60 degrees Celsius ".
In addition, the present invention also proposes a kind of computer-readable recording medium, it is stored with the computer-readable recording mediumApplication management program, realizes following operation when the application management program is performed by processor 110：
It is each under each usage scenario for obtain current usage scenario information, prestoring when platform application program is cleared up on triggeringApplication program used first use under probability, and each usage scenario that types of applications program is used second use it is generalRate；
Currently used scene information, each first are input to default Bayesian network using probability and each second using probabilityIn network probability calculation model, each background application is calculated what currently used scene was used and the 3rd uses probability；
Close the 3rd background application for being less than predetermined probabilities threshold value using probability.
Further, following operation is also realized when aforementioned applications management program is performed by processor 110：
Using the user preference value of each background application prestored, the 3rd of each background application of correspondence amendment usesProbability.
Further, following operation is also realized when aforementioned applications management program is performed by processor 110：
Choose a background application；
Based on the user preference value for the background application chosen, and default user preference value is with correcting reflecting for probabilityRelation is penetrated, it is determined that the amendment probability corresponding to the background application chosen；
The 3rd of the background application the chosen probability and value for using probability and amendment probability is calculated, by the probability of calculatingWith value probability is used as the revised 3rd；
Continue to choose a background application, until each background application is selected, complete to each background application journeyThe 3rd of sequence uses the amendment of probability.
Further, following operation is also realized when aforementioned applications management program is performed by processor 110：
Count and store the user preference value of each application program.
Further, following operation is also realized when aforementioned applications management program is performed by processor 110：
Count number of run of each application program in preset time period, and the resident duration on foreground；
According to number of run and each self-corresponding weights of resident duration, number of run based on each application program and it is resident whenIt is long, calculate and store the user preference value of each application program.
Further, following operation is also realized when aforementioned applications management program is performed by processor 110：
First for counting and storing each application program under each usage scenario uses probability.
Further, following operation is also realized when aforementioned applications management program is performed by processor 110：
Preset types of applications program under each usage scenario second uses probability.
Further, following operation is also realized when aforementioned applications management program is performed by processor 110：
