200.This is used for the method for output information, comprising the following steps:
Step 201, the characteristic information of at least one point map in presumptive area is obtained, and according to scheduled scale bar
Presumptive area is divided at least one region of search set by set.
In the present embodiment, can lead to for the executing subject of the method for output information (such as server shown in FIG. 1)
Wired connection mode or radio connection are crossed from least one point map in third-party server acquisition presumptive area
Characteristic information.Presumptive area can be city, province, a country etc..Characteristic information may include but be not limited to following at least one
: area, temperature, if overlooking, brand and type.Temperature can be the retrieval amount in predetermined period, click volume.Overlooking finger
It is POI whether on kerbside, if it is, can be identified with 1.If not can then be identified with 0.Brand can with 1 come
Mark is famous brand, and 0 is non-famous brand.Map can be zoomed in and out according to scale bar, and the POI shown under different scale bars is different.It can
Presumptive area different regions of search will be divided into according to different scale to gather.Each scale bar can correspond to a field of search
Domain set.Scale bar is bigger, then region of search is smaller.For example, the scale bar of 1cm:5m, region of search can be that radius is 5m circle
Region.Region of search can be determined by R tree.R tree is the tree data structure for doing GML data storage.Such as to geographical position
It sets, rectangle and this kind of multidimensional data of polygon establish index.
The demand for the POI that ratio each on map base map is shown is as follows:
Table 1
Here level refers to the display level of POI.For example, it can be in 19- if the level of some POI is 19
21 layers of display, and cannot be shown in the layer less than 18.
Base map generally refers in drawing course, is placed on the bottommost of multiple figure layers.Constitute the basic framework of the base map.Have
After base map, so that it may element, that is, data set associated therewith be carried out in the form of figure layer orderly be superimposed upon on base map.
The POI data type of base map is complicated, shows that the principle of POI is in low scale bar to recognize city as mesh on base map
, it should preferentially show airport, railway station, city terrestrial reference, the POI such as large-scale scenic spot, with positioning and city spy under large scale
For the purpose of rope, popular POI should be shown, be clear to POI, brand class POI, POI at the front etc..It should be different in urban district and suburb
Exhibition strategy, prevent suburb large area from there is no the case where POI.Identical power cannot be used for a line city and four line cities
Recomputation strategy avoids under certain scale bars POI excessively intensive or excessively sparse problem etc..
Step 202, for the point map at least one point map, which is determined according to the characteristic information of the point map
The weight of point.
In the present embodiment, the characteristic information of POI includes but is not limited to area, and temperature is overlooking, brand, type.Type can
Including housing type (for example, apartment, residential area etc.), place function type (for example, hospital, supermarket etc.), colleges and universities' type (example
Such as 985,211, high official rank).3 class weights can be calculated according to these features, are area weight area_rank, temperature power respectively
Weight query_rank, comprehensive weight all_rank.Wherein area_rank is relative value.Query_rank can face according to temperature
Street, brand calculate.All_rank is then that according to area, temperature is overlooking, and brand calculates.
It can be pre-processed before calculating weight.For example, it is too small (such as being no more than 2 retrievals weekly) to filter out temperature
POI.The POI excessive to temperature can be smoothed, such as open radical sign, take logarithm etc..
It can conduct normalized after weight calculation, [0,10000] arrived into the standardization of calculated weight.
For the POI not being filtered, weight can be determined as follows:
1, according to the temperature in the characteristic information of the POI, if overlooking, brand, type determine the temperature weight of the POI.
Hot_rank=k* (q)+l*k1+b*k2
Wherein, hot_rank indicates temperature weight, and k indicates to adjust weight parameter, and q indicates hot value, and k1 indicates that overlooking data add
Weight, l indicate whether overlooking, and k2 indicates branding data weighted value, and b indicates whether it is famous brand.
Then [0,10000] is arrived into hot_rank standardization.
2, according to the area in the characteristic information of the POI, temperature, type determines the comprehensive weight of the POI.
All_rank=α * k* (a)+β * k* (q)
Wherein, all_rank indicates that comprehensive weight, k indicate to adjust weight parameter, and q indicates hot value, and α indicates area tune power, a table
Show that area, β indicate temperature tune power.
3, according to the area in the characteristic information of the POI, the POI total amount in type presumptive area determines the area of the POI
Weight.
The non-small city area_rank=k* (a)
The small city area_rank=k* (a)+k* (q)
Wherein, area_rank indicates that area weight, k indicate to adjust weight parameter, and q indicates hot value, and a indicates area.It can basis
POI total amount divides small city and non-small city in region, for example, if POI total amount is greater than POI total amount threshold value (for example, 150,000),
Then think to be non-small city, otherwise it is assumed that being small city.
Then [0,10000] is arrived into area_rank standardization.
The specific explanations of POI characteristic quantity in above formula are as shown in table 2:
Table 2
The effect of all types of weights is as shown in table 3:
Table 3
In some optional implementations of the present embodiment, also weight parameter can be adjusted to carry out tune power according to temperature, type etc..
Adjusting weight parameter may include temperature, type, other tune power etc..It is weighed according to temperature tune can include: the first heat degree threshold is higher than to temperature
POI carry out high fever weighting, can also to temperature lower than the second heat degree threshold POI carry out low-heat drop power.It can according to type tune power
Include: to drop to weigh to cell class POI, non-key university's class POI is dropped and is weighed.Other adjust power can include: brand class weighting, it is overlooking plus
Power, small city tune power etc..
Step 203, for the scale bar in scale bar set, by the power of point map in the corresponding region of search of the scale bar
The maximum point map of weight is determined as the point map shown under the scale bar.
In the present embodiment, bottom-up building carries out step by step from maximum ratio ruler 1cm:5m to 1cm:20km scale bar
The election of POI, each scale bar elect the maximum POI of weight according to region of search.For example, in scale bar 1cm:5m, at this time
For initial level 21, the circular scope of each radius 5m is interior to choose a POI, and the weight of the POI is maximum.The weight of POI is maximum
It can be temperature weight maximum or comprehensive weight be maximum, can also be that the weighted sum of temperature weight and comprehensive weight is maximum.
In some optional implementations of the present embodiment, the classification of POI is the display scale ruler level of determining POI
, 16 grades or more of POI is constrained by area weight area_rank.
In some optional implementations of the present embodiment, for being greater than the ratio of predetermined ratio value in scale bar set
The maximum point map of temperature weight of point map in the corresponding region of search of the scale bar is determined as showing under the scale bar by ruler
Point map.For example, using hot_rank to refer to as classification when being more than or equal to 17 grades (scale bar 1cm:100m~1cm:5m)
Mark,
In some optional implementations of the present embodiment, for being less than or equal to predetermined ratio value in scale bar set
The maximum point map of comprehensive weight of point map in the corresponding region of search of the scale bar is determined as under the scale bar by scale bar
The point map of display.For example, be less than or equal to 16 grades (scale bar 1cm:20km~1cm:200m) when, use all_qurey as
Graded index.One area weight threshold value can be set for every level, when the area weight of the POI of this level is greater than the level
It mays be eligible to compete next level when area weight threshold value.
It is at war with classification in hierarchical policy from the highest level (such as 21) toward low level-one (such as 11).So that it is determined that going out
The displayable level of POI, i.e., can show the POI under which scale bar.
Step 204, for the scale bar in scale bar set, the information of the point map shown under the scale bar is exported.
In the present embodiment, the information of point map includes but is not limited at least one of following: title, coordinate, is divided at classification
Class.Displayable POI under output different scale can be layered.The way of output can be the terminal device for being output to user, may be used also
To be output in storage medium.Or the POI information shown under each scale bar is sent out again when user passes through terminal searching map
Give terminal.
With continued reference to Fig. 3 a, 3b, Fig. 3 a, 3b are the application scenarios according to the method for output information of the present embodiment
One schematic diagram.Fig. 3 a, 3b application scenarios in, server obtains the characteristic information of about 700,000 POI in Beijing.Then root
The weight of each POI is calculated according to the characteristic information of POI.As shown in Figure 3a, it when scale bar is 1cm:5m (21 layers), can be shown on map
Show POI1-POI4.When scale compression is to 1cm:10m (20 layers), it can not all show POI1-POI4, need from them
The maximum POI of weight is selected in the search radius of 10m as upper one layer (20 layers) displayable POI.Due to the power of POI1
The great weight in POI2, so POI1 wins, POI1 can be in upper one layer (20 layers) display.The weight of POI3 is greater than the power of POI2
Weight, so POI3 wins, POI3 can be in upper one layer (20 layers) display.The weight of POI4 is greater than the weight of POI3, so POI4 wins
Out, POI4 can be in upper one layer (20 layers) display.Similarly, the weight of POI1 is greater than the weight of POI3, and the weight of POI4 is greater than POI3
Weight, scale bar be 1cm:50m when POI1 can 19 layers show.The weight of POI1 is greater than the weight of POI4, in scale bar
POI1 can be shown at 18 layers when for 1cm:100m.
Left figure is the POI that existing layered mode is shown in Fig. 3 b, and right figure is what presently filed embodiment obtained
POI.Wherein, POI indicated by arrow is the POI never shown in left figure in right figure.It can be seen that presently filed embodiment can
More POI are shown under the premise of not influencing bandwagon effect.
The method provided by the above embodiment of the application is shown under different scale by being selected according to the weight of POI
POI so that showing more rationally to improve the clicking rate and conversion ratio of point map.
With further reference to Fig. 4, it illustrates the processes 400 of another embodiment of the method for output information.The use
In the process 400 of the method for output information, comprising the following steps:
Step 401, the weight of at least one point map in presumptive area is obtained, and the level of each point map is set as
Initial level.
In the present embodiment, it obtains and walks for the executing subject of the method for output information (such as server shown in FIG. 1)
The weight of at least one point map (i.e. POI) in rapid 202 presumptive areas determined.The level of POI in the region is set
It is set to initial level, such as 21.
Step 402, R tree is constructed based at least one point map.
In the present embodiment, R tree is the tree data structure for doing GML data storage.Such as to geographical location, square
Shape and this kind of multidimensional data of polygon establish index.R tree can be used to store the spatial information on map, such as restaurant address,
Or be used to construct street on map, it builds, the polygon at lake edge and coastline.Then it can be answered and " be searched with it
Museum within my 2 kms ", " all sections of the retrieval within my 2 kms " (and then it is shown in navigation system
In) or such issues that " search (linear distance) nearest gas station ".R tree can also be used to accelerate using including great-circle distance
The Nearest Neighbor Search of various distance metric modes inside.
Step 403, the point map in R tree is traversed, determines the region of search of each point map.
In the present embodiment, different levels correspond to the region of search of different scale.For example, the corresponding ratio of initial level 21
Example ruler is 1cm:5m.Scanned in the range of radius 5m.For 11 levels, then corresponding scale bar is 1cm:10km,
Search radius is 10km.
Step 404, determine whether the weight of each point map is maximum in region of search.
In the present embodiment, the weight that each level is used to compare can be unified for temperature weight or comprehensive weight or temperature
The weighted sum of weight and comprehensive weight.Also different weights can be selected to be compared according to different levels.For example, being less than or equal to 16
Level use comprehensive weight.Level more than or equal to 17 uses temperature weight.So that being realized during classification big
Scale bar pays the utmost attention to temperature, the features such as overlooking, and small scale pays the utmost attention to area, the features such as temperature.
Step 405, the level of the maximum point map of weight in region of search is subtracted 1.
In the present embodiment, the maximum point map of weight is won in competition in region of search, can be aobvious in a upper level
Show, for example, winning in 21 layers of competition, can be shown at 20 layers.The point map of competition failure cannot continue to participate in subsequent competing
It strives.
Step 406, whether the level of the point map filtered out has been smallest tier.
In the present embodiment, smallest tier is uppermost one layer, can be 1 and is also possible to 11.It is corresponding if it is 11
In scale bar 1cm:10km.If having filtered out topmost one layer of point map, whole process terminates.If also non-iteration
Topmost one layer is screened, then continues iteration screening.
Step 407, it is determined whether needs according to area screened by weight?
In the present embodiment, if iteration screens scheduled level, i.e., for distinguishing using temperature weight still
The level of comprehensive weight, for example, 17 layers, then need the point map using area weight greater than the area weight threshold value of this layer as competing
Strive 16 layers of candidate point map.If being also not up to 17 layers, step 402 is continued to execute, it is no to then follow the steps 408.
Step 408, screening is greater than the point map of area weight.
In the present embodiment, for the point map less than or equal to scheduled level (16 level), space required weight is greater than
The area weight threshold value of this layer could participate in the competition of next round.That is, area is less than the point map of the area weight threshold value of this layer
It will not be in the level less than or equal to 16 and show.
In some optional implementations of the present embodiment, the scale bar pair in target area is determined by following steps
The area weight threshold value for the level answered:
Step 4081, candidate point map quantity and scheduled reference map are counted under the scale bar in acquisition target area
Amount, scheduled reference area weight threshold.
In the present embodiment, target area can be the region different from reference area.For example, reference area is Beijing,
I.e. using the area weight threshold value of each level in Pekinese as reference area weight threshold.Candidate point map is the ground in target area
Figure point.The area weight threshold value of each level in other cities can be calculated.Such as seek the area weight threshold of each level of Tianjin
When value, need to obtain the reference area weight threshold of the POI total amount of Tianjin and each level of reference area.
Step 4082, in response to the small predetermined value of ratio of candidate point map quantity and reference map point quantity, by benchmark
The ratio of figure point quantity and candidate point map quantity is determined as adjusting multiple, true based on adjustment multiple and reference area weight threshold
The area weight threshold value for the corresponding level of the scale bar in region of setting the goal.
In the present embodiment, predetermined value can be 0.7, i.e., the POI total amount of target area to be predicted is if it is less than benchmark
0.7 times of region POI total amount then needs to adjust target area according to the reference area weight threshold of each level of reference area
Each level reference area weight threshold.Adjustment multiple can be the ratio of reference map point quantity and candidate point map quantity
Value.
The area weight threshold value of each level of target area is calculated by following formula:
Rnew=rmax- (rmax-r) * n
Wherein, rnew is the area weight threshold value of each level of target area, and rmax is the area weight of reference area
Maximum value, 10000, the r that can be standardization is reference area weight threshold, and n is adjustment multiple.
For example, the area weight threshold value of such as 10 grades of Pekinese is 9999.516
The calculated adjustment multiple n=5 in some city
The then area weight threshold value in 10 grades of this city are as follows:
