[embodiment]
Understand for technical characterictic, goal of the invention and beneficial effect to invention have more clearly, contrast description of drawings embodiment of the present invention at present, identical label is represented the part that step is identical in each figure.In this article, " schematically " expression " is served as instance, example or explanation ", should any diagram, the embodiment that be described to " schematically " in this article be interpreted as a kind of preferred or have more the technical scheme of advantage.
At first with reference to figure 1, one embodiment of the present invention comprise adress analysis unit 1 based on geographical entity distribution address inquiry unit, space interpolation unit 2, and unit 3 is returned in the address.
Adress analysis unit 1 is used for obtaining at least one and the Approximate Address of the matching addresses to be checked of input at address database.
This address database is the standard normal form address base of a tree structure, and this tree-shaped standard normal form address base has some branches, and the end of each branch has at least one leaf node.For the concrete structure of this address database more clearly is described, below be that example is done detailed description with the address database of the electronic chart in the People's Republic of China (PRC) administrative region.Generally speaking, the administrative division of China comprises four levels: first level is province/autonomous region/municipality directly under the Central Government; Second level is city/autonomous prefecture; The 3rd level is district/county; The 4th level is township/town/street.These four levels are relatively-stationary, and its quantity and title are can add up easily corresponding to the region name of various places to obtain.Therefore, in address database, these four levels are merged the ground floor that is generically and collectively referred to as the address database tree structure, promptly territory, administrative area layer correspondingly is designated first level and is province/autonomous region/municipality directly under the Central Government; Second level is city/autonomous prefecture; The 3rd level is district/county; The 4th level is township/town/street.Specific address title below the 4th level is numerous and complicated, vast as the open sea then; Yet; This many specific address title can be summed up as three kinds of address styles: i.e. road class address, type address, zone and terrestrial reference class address; These three types of addresses are generically and collectively referred to as the second layer of address database tree structure, i.e. subaddressing layer.Described road class address is used to define the specific address with headed by the road, for example: a road b number, a road b lane etc.A type address, described zone is used to define the specific address with headed by the sub-district, for example: b of a sub-district, a sub-district b phase.Described terrestrial reference class address is used to define a concrete location point, for example: a mansion, b park etc.
Described adress analysis unit 1 comprises address lookup module 10 and matching addresses module 12.
Address lookup module 10 is used for whether having the known address of mating fully with the address to be checked of input in the address database inquiry.On all four address, normal form normal address in described herein " known address of coupling fully " refer to and the said address database.Described normal form normal address comprises three kinds of road class address, type address, zone and terrestrial reference class addresses, and road class address is used to define the specific address with headed by the road, and for example: a road b number, a road b do etc.A type address, described zone is used to define the specific address with headed by the sub-district, for example: b of a sub-district, a sub-district b phase.Described terrestrial reference class address is used to define a concrete location point, for example: a mansion, b park etc.Illustrate: a complete specific address " No. 3 HaiLong Buildings in Zongguancun Street, Haidian District, Beijing City " will produce the road class address " No. 3, Zongguancun Street, Haidian District, Beijing City " of a normal form standard and the terrestrial reference class address of a normal form standard " Haidian District, Beijing City dragon mansion " in affiliated address database.If the user imports whole address informations of above any one address to be checked and inquires about; Then address lookup module 10 can find corresponding normal form address in described address database; And directly export Query Result, need not enabling address matching module 12 this moment.Otherwise, if the address to be checked of user's input and described normal form ADI address incomplete coupling then need enabling address matching module 12.It is to be noted; Because the normal form normal address in the address database is divided into three kinds of road class address, type address, zone and terrestrial reference class addresses; In address lookup module 10, may inquire several normal form normal addresses corresponding to same address to be checked; This moment need be according to the preferential the highest address of importance of exporting of predefined importance rule as final query result; The rule of described predefined address importance is: zone type address importance is the highest, and terrestrial reference class address importance is taken second place, and road class address importance is minimum.
Matching addresses module 12 is used for when not having fully the known address of coupling obtaining at address database the Approximate Address of at least one and matching addresses to be checked, and the Approximate Address of described and matching addresses to be checked is used for next step space interpolation unit 3.Described " with the Approximate Address of matching addresses to be checked " obtains through following method: at first, the Approximate Address of storing in the said address database is divided into three types: road class address, type address, zone and terrestrial reference class address; Secondly, if in said address database, obtain one or several of the same type with Approximate Address matching addresses to be checked, then this address directly is used for next step space interpolation unit 3; In addition; If in said address database, obtain two or more and matching addresses to be checked and belong to dissimilar Approximate Addresses; Then according to predefined address importance priority select one type of importance the highest and with the Approximate Address of matching addresses to be checked, and such address directly is used for next step space interpolation unit 3.Approximate Address described herein obtains through the rule that in system, is provided with in advance; For example: if the address to be checked of user's input is " No. 4, Zongguancun Street, Haidian District, Beijing City "; Yet have only three road class address informations such as " No. 1, Zongguancun Street, Haidian District, Beijing City ", " No. 3, Zongguancun Street, Haidian District, Beijing City ", " No. 5, Zongguancun Street, Haidian District, Beijing City " in the normal form address database; " No. 4, the Zongguancun Street, Haidian District, Beijing City " of coupling fully not supposes that the rule that in system, is provided with in advance is: differ No. 10 with the road number of address to be checked and be Approximate Address with interior address.Then three normal form normal addresses in the address database all can be used as " Approximate Address ".
Address style judge module 30 is used for judging that the Approximate Address with matching addresses to be checked that obtains from the adress analysis step belongs to any of described three kinds of address styles, one of promptly belongs in road class address, type address, zone or the terrestrial reference class address.Described road class address is used to define the specific address with headed by the road, for example: a road b number, a road b lane etc.A type address, described zone is used to define the specific address with headed by the sub-district, for example: b of a sub-district, a sub-district b phase.Described terrestrial reference class address is used to define a concrete location point, for example: a mansion, b park etc.
When address type judging module 30 judges that the Approximate Address of coupling is terrestrial reference class address, selected element interpolation component 320.Described point interpolation assembly 320 based on the coordinate of the known landmarks class address of matching addresses to be checked, on the desired direction of the input information of address to be checked, add side-play amount.For example: if the information of looking into of waiting of input is " 100 meters in HaiLong Building south, Haidian District "; Then at first in address database, find the pairing normal form of the Approximate Address normal address " Haidian District, Beijing City dragon mansion " of coupling; The suitable distance of skew to the south on map then, and the address coordinate after will squinting is exported as final query result.
When address type judging module 30 judges that the Approximate Address of coupling is road class address, selection wire interpolation component 322.Described line interpolation component 322 is at first judged the quantity of the known homonymy address of road class address; If the quantity of known homonymy address is greater than one, then with reference to the address coordinate of the address coordinate information acquisition address to be checked of described known homonymy address; If the quantity of known homonymy address only has one, the address coordinate of the address coordinate information acquisition address to be checked of the known heteropleural address of the said road class of reference address.2,4,6... 1,3,5... illustrate: the general queueing discipline of the number of Chinese city road is: a side of road is the odd number doorplate:, the opposite side of road is the even number doorplate:.If the address to be checked of input is " No. 3, Zongguancun Street, Haidian District, Beijing City ", then can produce two kinds of different deterministic processes.One of process: if in address database, inquire about to the similar address of coupling comprise " No. 1, Zongguancun Street, Haidian District, Beijing City ", " No. 5, Zongguancun Street, Haidian District, Beijing City ", " No. 7, Zongguancun Street, Haidian District, Beijing City " etc.; Then can carry out the line interpolation, thereby draw the coordinate figure in " No. 3, street, Zhong Guan-cun " based on the coordinate information in the address " No. 1, street, Zhong Guan-cun " of road homonymy, " No. 5, street, Zhong Guan-cun ", " No. 7, street, Zhong Guan-cun ".Two of process: if in address database, inquire about to the similar address of coupling comprise " No. 1, Zongguancun Street, Haidian District, Beijing City ", " No. 2, Zongguancun Street, Haidian District, Beijing City ", " No. 4, Zongguancun Street, Haidian District, Beijing City ", " No. 6, Zongguancun Street, Haidian District, Beijing City " etc.; Then can carry out the line interpolation, thereby draw the coordinate figure in " No. 3, street, Zhong Guan-cun " based on the coordinate information in the address " No. 2, street, Zhong Guan-cun " of road heteropleural, " No. 4, street, Zhong Guan-cun ", " No. 6, street, Zhong Guan-cun ".
When address type judging module 30 judges that the Approximate Address of coupling is class address, zone, select face interpolation component 324.The coordinate information of the address to be checked that described interpolation component 324 will be imported and several compare through the adress analysis step coordinate information with known region class address matching addresses to be checked that obtain; If the coordinate of the address to be checked of input between the coordinate of described some known region classes address, is then selected according to inserting in the method for linear difference; If the coordinate of the address to be checked of input exceeds the included scope of coordinate of described some known region classes address; Then in described some known region classes address, select an immediate address of coordinate with the address to be checked of input, and on the basis of the coordinate of said address, add that suitably side-play amount is as finally exporting the result.Illustrate: the general queueing discipline of the groups of building of Chinese city sub-district is: 1,2,3 .....If the address to be checked of input is " 10 of Yue Yuan sub-districts, Haidian District, Beijing City ", then can produce two kinds of different deterministic processes.One of process: if in address database, inquire about to the similar address of coupling comprise " 1 of Yue Yuan sub-district, Haidian District, Beijing City ", " 9 of Yue Yuan sub-districts, Haidian District, Beijing City ", " 18 of Yue Yuan sub-districts, Haidian District, Beijing City " etc.; Then can sketch the contours of the general profile of this sub-district based on these address informations; And insert in carrying out based on " 9 of Yue Yuan sub-districts, Haidian District, Beijing City " on this basis and handle; Let the coordinate figure of address to be checked " 10 of Yue Yuan sub-districts, Haidian District, Beijing City " drop in the described general profile, as final query result.Two of process: if in address database, inquire about to the similar address of coupling comprise " 1 of Yue Yuan sub-district, Haidian District, Beijing City ", " 5 of Yue Yuan sub-districts, Haidian District, Beijing City ", " 9 of Yue Yuan sub-districts, Haidian District, Beijing City " etc.; The problem of this moment is to sketch the contours of the general profile of this sub-district based on known Approximate Address; Thereby can't carry out migration processing arbitrarily; Otherwise the coordinate that may drop into other known addresses by error gets on; In described some known region classes address, select an immediate address of coordinate " 9 of Yue Yuan sub-districts, Haidian District, Beijing City " with the address of importing to be checked this moment; And on the basis of the coordinate of said address, suitably add side-play amount, guarantee not conflict, as final output result with the known address.
Degeneration unit, address 5 is used for can't be in said adress analysis unit 3 when obtaining any Approximate Address that is complementary; The degenerate least significant end address of described address to be checked, and the address after will degenerating is as the inquiry again in the adress analysis step of new address to be checked.Degeneration unit, described address 5 is not the necessary member that solves the device of technical matters of the present invention, but its address information at address database can play a role in incomplete.Illustrate: if the address to be checked of input is " No. 3 HaiLong Building B1s in Zongguancun Street, Haidian District, Beijing City 10-4 number "; And the Approximate Address of the coupling that in address database, can inquire is " No. 3, Zongguancun Street, Haidian District, Beijing City ", " Haidian District, Beijing City dragon mansion "; Then select directly to degenerate " B1 10-4 number " in (deletion) address to be checked, and the address after will degenerating " No. 3 HaiLong Buildings in Zongguancun Street, Haidian District, Beijing City " get into adress analysis unit 1 again as new address to be checked and inquire about.
