Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts
Embodiment shall fall within the protection scope of the present invention.
Fig. 1 is that a kind of control layout applied based on Android of the embodiment of the present invention recommends the flow diagram of method, such as
Shown in Fig. 1, this method includes：
S1, the data set of dynamic interface, is parsed, extraction process when obtaining operation, is established after obtaining spatial database
Index；
S2 carries out matching retrieval, extraction, sliding-model control to the keyword that user provides, obtains alternate layout scheme；
S3 scores to alternate layout scheme, is laid out accordingly to user according to from high to low recommendation of scoring.
S1 further comprises：
S11, separate unit interface data collection when obtaining operation carry out dissection process, and extraction obtains the attribute of all controls；
S12, carries out the attribute of all controls parsing classification processing, and extraction obtains control text message, control type, control
Part is laid out relevant control property；
S13 extracts keyword, the search key as control property database to control text message；
To the control of no text message, then control type is taken as search key；
It is also possible to control type and the keyword of control text message is taken to be combined as search key；
S14 forms control property searching database with reference to three kinds of situations, establishes corresponding index.
Specifically, the data set of dynamic interface derives from the uniform velocity traveling circle obtained from Black-box Testing when being run described in S1
The data in face, including：The attribute of the instant sectional drawing of dynamic interface, the hiberarchy data at interface, each control during operation.
Parsing classification processing is carried out described in S12 to control property, is largely divided into two classes：
One kind be with the relevant attribute of control function, including the type of control, for example, common button,
Textview, the property clicked of control, control visibility, control content of text etc.；Since the type of control generally determines control
The property clicked and visibility of part, therefore we establish index using control type and text message for control.
One kind be with the relevant space attribute of control layout, including coordinate, length and width.
In a particular embodiment, the class name combination for the property that usually has levels from the control type name collected during operation, example
Such as " androidwidgetButton ", last class name can represent the type and function of control, for the ease of storage and
Retrieval, takes last class name and small letter is turned to the types index of control.The text of control is usually short text, frequently even
Only there are one word, therefore a small amount of several keywords are enough to express the semantic information of control.
It is the text envelope using LDA models to all controls to extract keyword described in S13 to control text message
Breath modeling, so as to obtain the distribution of the keyword in theme, the theme then being had according to text is higher from wherein selection frequency
Keyword index of several keywords as retrieval control.
S2 further comprises：
S21 provides the description type keyword of target widget type or control text message keyword according to user, passes through
Matching control property searching database carries out retrieving corresponding index, obtains the topology data collection about target widget；
S22 carries out sliding-model control to the topology data collection of target widget, obtains layout gathering and closes, and each cluster that is laid out is
For alternate layout scheme；
The control retrieved corresponding to corresponding index described in S21 by the way that control property searching database is matched to carry out is
The target widget that user seeks.After retrieval, the topology data of every record is extracted, forms the topology data of target widget
Collection.
Sliding-model control is carried out to the topology data collection of target widget described in S22, mainly utilizes DBSCAN clustering algorithms,
In order to which Clustering Effect is more compact, it is 10 that we, which set field radius, density 1.Wherein, the radius of neighbourhood determines that each point is found
With the range of cluster, density determines whether the topology data collection sample territory of a target widget can be considered as a cluster class, i.e.,
Form the topology data collection sample size threshold value of the target widget of cluster.Depending on the two parameters are needed because of specific sample data, but
Principle exactly cannot be any one data when noise filtering is fallen, therefore the parameter of density should be relatively low there are one being, base then will
Density is set as 1.In addition to the effect of cluster is compact, the radius of neighborhood should set relatively low, then be set as 10.
Similar target widget topology data is clustered, and is called gathering for a kind of target widget topology data subset
Cluster is laid out, the layout mean value of layout cluster is then updated to the layout of all samples in this cluster, thus very similar mesh
It is same layout scenarios to mark control layout data sample stipulations, so as to achieve the purpose that topology data collection sliding-model control.
Further, the layout gathering obtained through S22 is closed intuitively shows user to see by thermodynamic chart, wherein, target
One layout of control represents that the perimeter of this rectangle frame is exactly the number of the pixel occupied by it with a rectangle frame, as
The brightness of vegetarian refreshments reflects the frequency of the rectangle frame repeated in the pixel, if as shown in Fig. 2, some area in figure
Domain is brighter, and the layout for illustrating to select the region is more frequent.
S3 further comprises：
S31 obtains alternate layout scheme, carries out quantum chemical method processing, obtains the scoring of the alternate layout scheme；
S32 obtains the scoring of each alternate layout scheme, according to its scoring from high to low to each alternate layout scheme into
Row sequence obtains several preceding alternate layout schemes and recommends user.
Wherein, it is the scoring using the representativeness and stability of quantization placement scheme that quantum chemical method processing is carried out described in S31
Method.The representativeness of quantization placement scheme is to solve according to similar in highest frequency recommends layout that can not judge the frequency of occurrences
In the case of the layout of highest frequency whether have representative problem.Representativeness is embodied in certain layouts and is focusing specifically on an area
Domain, and the frequency of occurrences is higher.We are by the use of local distribution high-lighting as representative measurement.Consider local distribution high-lighting
Be because usually there is the situation of several cluster nestings in a region in the different layouts of control, if in a region,
In a cluster it is very big with respect to other number of clusters amount superiority, illustrate more representative in this region.
Use LARepresent the layout (x, y, h, w) of target widget A, wherein, x, y are target widget A coordinates, and h, w are target control
The length and width of part A.This is a four-dimensional stochastic variable,Represent LALayout cluster sample set.Layout after cluster
Cluster isA subset, use aiIt represents.S is represented and aiAll gatherings of overlapping are closed.apExpression and aiIn all clusters of overlapping
The cluster of quantity maximum.E(ai) represent aiThe average layout of cluster, Min (| ais|) represent S in cluster quantity minimum value, Max (| ais
|) represent the maximum value of the quantity of cluster in S, then cluster aiHigh-lighting CSiIt can be calculated by following mode：
CSi=(| ap|-Min(|ais|))/Max(|ais|)-Min(|ais|)
The stability of quantified goal control layout is to solve the problems, such as not judging alternate layout scheme reliability.Surely
The qualitative layout for being mainly reflected in target widget has more stable central tendency, if the layout of opposite target widget is very much
Different coordinates and shape, which differ, to be all distributed, and the frequency without occurring is all more dispersed, is exactly unstable, random table
It is existing.
Because overall randomness is easier to quantify, using comentropy and the frequency of occurrences of different layout clusters, and
Stability is inversely proportional with randomness, therefore we measure the cloth score of the game of the entire topology data collection of control using the inverse of comentropy
Cloth stability.
We measure the randomness of layout cluster distribution by comentropy.Entropy is bigger, then randomness is bigger.Because stability with
Randomness is inversely proportional, therefore weighs stability with the reciprocal of entropy.PiRepresent the sample of the frequency of occurrences, the i.e. cluster of some layout cluster
Quantity accounts for the ratio of total layout sample set.The configuration stability H of target widget is calculated in the following manner：
H=1/ ∑s Pi*logPi
For some layout cluster, local high-lighting is higher, and overall randomness is lower, then more representative, and scoring should
This is higher, therefore final scoring formula is as follows：
Score=CSi+H
The corresponding scoring of all layout clusters of target widget is then calculated, then to these marking and queuings, several preceding scorings
Highest layout cluster recommends user as recommendation placement scheme.

Quantum chemical method processing is the methods of marking of the representativeness and stability using quantization placement scheme.Use LARepresent target widget A's
It is laid out (x, y, h, w), wherein, x, y are target widget A coordinates, and h, w are the length and width of target widget A.This is one four-dimensional random
Variable,Represent LALayout cluster sample set.Layout cluster after cluster isA subset, use aiIt represents.S
Expression and aiAll gatherings of overlapping are closed.apExpression and aiThe cluster of quantity maximum in all clusters of overlapping.E(ai) represent aiCluster is put down
It is laid out, Min (| ais|) represent S in cluster quantity minimum value, Max (| ais|) represent S in cluster quantity maximum value, then
Cluster aiHigh-lighting CSiIt can be calculated by following mode：
CSi=(| ap|-Min(|ais|))/Max(|ais|)-Min(|ais|) 。
7. a kind of control layout based on Android application as claimed in claim 5 recommends method, which is characterized in that the progress
Quantum chemical method processing is to be fallen using in the representativeness of quantization placement scheme and the methods of marking of stability by what comentropy was measured
Number weighs stability.PiRepresent the frequency of occurrences of some layout cluster, i.e. the sample size of the cluster accounts for the ratio of total layout sample set.
The configuration stability H of target widget is calculated in the following manner：
H=1/ ∑s Pi*logPi
For some layout cluster, local high-lighting is higher, and overall randomness is lower, then more representative, and scoring should be got over
Height, therefore final scoring formula is as follows：
Score=CSi+H 。
