In one embodiment of the present disclosure, the target geographic block coding is mapped as comprising the target geographic block
When the coding of target group, mapping can be accomplished in several ways.It is mapped for example, can be realized by code mapping table.
In one embodiment of the present disclosure, the target geographic block coding is mapped as comprising the target geographic block
Before the coding of target group, need to pre-establish mapping relations for the mapping, the method for pre-establishing mapping relations, referring to figure
Shown in 2, include the following steps that S210 to step S230, is illustrated in detailed below:
In step S210, geocoding is carried out to geographic area to be indexed and obtains multiple geographical blocks and corresponding geography
Block coding, and at least one subregion is set by the multiple geographical block by preset rules.
In one embodiment of the present disclosure, geographic area to be indexed can be according to index client or server service
Area be configured, for example, serve China index server, geographic area to be indexed can be China；For another example, it services
Index server in Shanghai, geographic area to be indexed can be Shanghai.Due to geographic area to be indexed may be range compared with
Big geographic area, therefore geocoding can be carried out to geographic area to be indexed and obtain multiple geographical blocks and corresponding geography
Block coding, in order to the accurate index to point of interest.
It is regular it is possible to further set at least one for multiple geographical blocks in geographic range same in geographic area
Subregion, in the case that geographic area is bigger, can be set to multiple regular subregions.Wherein, preset rules can be with
It is default block number, default block number can be set to the form of two positive integer products, such as can be 4*4 block, 3*5 block etc..
Further, the specific geographic block number of subregion can be configured according to the attribute of geographical block, point of interest compared with
The default block number in more areas, subregion can take smaller value, and in the less area of point of interest, the default block number of subregion can be with
Take the larger value.For example, the point of interest that the geographical block for being located at Shanghai may include is more, and the geographical block for being located at Lhasa may include
Point of interest it is relatively fewer, therefore can will be located at Shanghai geographical block be combined into multiple regular subregions, each subregion packet
The geographical block number contained can take smaller value.The geographical block for being located at Lhasa is combined at least multiple subregions, wherein each sub-district
The geographical block number that domain includes can take the larger value；For another example the point of interest that the geographical block positioned at popular commercial circle includes is just than being located at city
The geographical block in suburb is more, therefore the geographical block number that the subregion for being located at popular commercial circle includes can take smaller value, will be located at city
The geographical block number that the geographical block subregion in suburb includes can take the larger value.In one embodiment of the present disclosure, for each
The setting that subregion presets block number can be identical.
In step S220, the multiple geographical block is commented according to the points of interest attribute in the multiple geographical block
Point.In one embodiment of the present disclosure, it can be scored according to the point of interest in geographical block, for example, can be according to interest
Bid, historic click-through rate, the attribute minute etc. of point, specifically score formula are as follows:
Wherein, n is the number for the point of interest for including, bid in geographical blockkFor the bid of k-th of point of interest, ctrkIt is k-th
The historic click-through rate of point of interest, poi_attrkFor the attribute point of k-th of point of interest, λ is rate of specific gravity.
In step S220, according to the scoring of the multiple geographical block, the geographical block in each subregion is distinguished
It is combined into the group with coding, with the mapping relations formed between geographical block coding and the coding of group.
It in one embodiment of the present disclosure, will be in each geographic area according to the scoring of the multiple geographical block
The geographical block method that is combined into the group with coding, wherein geographical block corresponding geography block coding is represented with O, group is represented with C
Coding include the following steps: referring to shown in Fig. 3
Step S310, by the highest geographical block O that scores in geography block ungrouped in a geographic areamaxiIt charges to
CiGroup.
Step S320 calculates CiIn group the scoring of all geographical blocks and, obtain CiThe scoring of group.
Step S330, if the CiThe scoring of group is greater than preset value, then stops to CiGeographical block is added in group, if the CiGroup
Scoring be less than the preset value, then will be with geographical block OmaxiIt is adjacent, the highest that scores and ungrouped adjacent geographical block charges to Ci
Group, until CiGroup scoring be greater than preset value or not with geographical block OmaxiUntil adjacent adjacent geographical block.
In one embodiment of the present disclosure, the preset value specific geographic area according to belonging to subregion
Attribute is configured.For example, when geographic area is divided according to city, the subregions of the large size cities such as Beijing, Shanghai, Guangzhou by
It is more in point of interest, preset value can be set to lesser value, to guarantee point of interest moderate number in the same set, reduced
The consumption of retrieval resource, and the subregion in the city less for other points of interest, can set preset value to biggish value,
To guarantee that point of interest quantity in the same set is more, the problem of searching interest point deficiency is avoided.
In one embodiment of the present disclosure, the adjacent geographical block includes that direct neighbor geography block and indirect neighbor are geographical
Block.As shown in figure 4, geographical block OmaxiUp and down four pieces be direct neighbor geography block, with geographical block OmaxiOn tilted direction
Adjacent geographical block is indirect neighbor's geography block, wherein the score of the digital representation geography block in geographical block.Will be with geography
Block OmaxiIt is adjacent, the highest that scores and ungrouped adjacent geographical block charges to CiIt, can be first according to scoring height (such as by commenting when group
Points 10,9,8,5 sequence) ungrouped direct neighbor geography block is added, according still further to scoring height (such as by 7,5,3,2 it is suitable
Sequence) indirect neighbor's geography block is added.
In one embodiment of the present disclosure, by the way that the geographical block in subregion is grouped, form geographical block with
Corresponding relationship between group, the corresponding mapping relations formd between geographical block coding and the coding of group.For example, geographical block is compiled
Code is that the geographical block of O1 joined C1 group, and the coding C1 of geographical block coding O1 and group forms mapping relations.
For the method for the above-mentioned point of interest index based on geographical location, embodiment of the disclosure provides one specifically
Implementation, referring to Fig. 5, detailed content is as follows:
Step S510 is obtained in user's request and is carried user's latitude and longitude information lat and lng.
Step S520 encodes (lat, lnt) by GEOHASH formula, obtains corresponding coding CODEX.
CODEX is mapped to system coding and obtains system coding NEW_CODEX by step S530 by code mapping table.
Step S540 determines extended coding according to NEW_CODEX score itself and request condition in the expansion unit,
Extended coding is NEW_CODEY.
Step S550, inverted index retrieve NEW_CODEX and NEW_CODEY, obtain interest point list.
