FIG. 1 is a flow chart of converting non-canonical addresses into canonical addresses. As shown in fig. 1, the conversion of the non-canonical address into the canonical address specifically includes:
(1) A non-canonical address is extracted from a non-canonical address repository.
(2) Chinese word segmentation is carried out on the non-standard addresses. The Chinese word segmentation can specifically use the conventional Chinese word segmentation technology. The word segmentation technique is mature in the prior art and is not described in detail herein.
(3) And (3) carrying out two-section division on the Chinese word segmentation result in the step (2), and dividing the non-standard address into a first front-section description and a rear-section description. The first preceding paragraph is described as non-canonical. According to a general convention, address descriptions are recited from a high address level to a low address level in a sequence from a large area to a small area according to the range of address areas. For example, from province county descriptions to building unit room numbers, etc. Therefore, the division of non-canonical addresses is also divided by address region. Preferably, the first front section is described as address description of non-standard province-city-county streets, and address description sequence mode is not matched, and non-standard text problems such as aliases are used. The latter section is described as an address description of building unit numbers. Because the address description of the building unit number only relates to numbers and is not easy to make mistakes, the later description is basically standard description, and the non-standard condition rarely occurs. The optimal dividing mode can ensure that the non-standardization of the whole address is normalized, maximally reduce redundant and unnecessary information conversion and quicken the information processing efficiency.
(4) The first data file is read and the first previous description is converted into GPS coordinates. The first data file may be a database file, where non-canonical address data, GPS coordinates, and a correspondence between the two are stored, and the database file may be read to convert the first previous description into GPS coordinates. Preferably, the first data file is selected as a GIS engine address conversion system, the first front description is input to a GIS engine address conversion interface, and the first front description is converted into a GPS coordinate point. GIS engine address translation systems are well established in the art, the principles and architecture of which are not described herein.
(5) And reading the second data file, and inversely converting the GPS coordinates into a second front section description. The second preceding description is an address description of a canonical province-city-county district street.
Wherein the second data file may be a database in which the address translation matrix is stored. The address conversion matrix construction method comprises the following steps:
(51) And determining the regional longitude and latitude range of the non-standard address, wherein if the regional longitude and latitude range is specific to a gas company, the regional longitude and latitude range is the regional longitude and latitude range of the gas enterprise service. The regional latitude and longitude range includes a latitude and longitude range. Where the longitude range is from the minimum longitude to the maximum longitude of the enterprise service area and the latitude range is from the minimum latitude to the maximum latitude of the enterprise service area.
(52) And establishing an address conversion matrix in the longitude and latitude range of the area. The elements in the address translation matrix are canonical address descriptions.
The longitude range includes a plurality of longitude value data points. The difference between adjacent longitude value data points is a fixed value. Preferably, the difference between adjacent longitude value data points is 0.0001 longitude. This is close to average step length of a typical person. The row of the address translation matrix is a canonical address description corresponding to the longitude value data points in each longitude range.
The latitude range includes a plurality of latitude value data points. The difference between adjacent latitude value data points is a fixed value. Preferably, the difference between adjacent latitude value data points is 0.0001 latitude. This is close to average step length of a typical person. The columns of the address translation matrix are canonical address descriptions corresponding to latitude value data points within each latitude range.
(53) The address translation matrix is stored in a second data file.
Every time there is a GPS coordinate, a canonical address description can be obtained in the address translation matrix. Because the longitude value data point and the latitude value data point in the address conversion matrix are small enough, namely, the length of the approximate step length, all the standard address descriptions can be necessarily obtained according to common general knowledge, so that no address error can be generated even if the GPS coordinates are not continuously valued.
Fig. 2 is a schematic diagram of an address translation matrix. As shown in fig. 2, a in the matrix ij The standard address description is that the angle mark i is the serial number of the longitude value data point, and the angle mark j is the serial number of the latitude value data point. Within the longitude range shown in fig. 2, x longitude value data points and y latitude value data points are taken together. a, a ij And a i+1,j Differing by 0.0001 longitude. a, a ij And a i,j+1 Differing by 0.0001 latitude.
(6) For the second front-end description, a standard front-end description is extracted. The second previous description may be a description that is convenient for data storage, for example, only store the province name "Jiangsu", in which step the province name may be converted into a standard description "Jiangsu province".
(7) And (3) superposing the back-end description of the step (3) after the standard front-end description to obtain the standard address.
The invention also discloses a coding method of the standard address, and fig. 3 is a flow chart of the coding method of the standard address. As shown in fig. 3, after the canonical address of step (7) is obtained:
(71) Address coding rules are formulated. The address coding rule is an address part rule for dividing the canonical address description into different levels; and digital coding rules of each address part rule are respectively set.
According to the common general knowledge, the address description method is to describe from a high-level address part to a low-level address part according to the area range of the address. Wherein the high-level address part refers to an address description with a large area range, such as a city and county district or the like, and the low-level address part refers to an address description with a small area range, such as a building unit room or the like. Therefore, it is an address part rule that divides an address into a plurality of levels from a large area to a small area according to an area range described by a canonical address.
Preferably, in the formulation of the address coding rule, the address part rule is set to be divided into a province-city-county part, a street part, a cell part, a building part, a unit part and a room part in order.
The digital coding rule of each address part rule is set respectively, namely, for each level of address part rule, a digital sequence is allocated to the address part rule, namely, a corresponding digital coding value is given to the address part rule. According to the characteristic of each basic address part rule, the digital coding value can be a natural number with a plurality of digits and sequentially coded, can be directly used as the digital coding of the existing administrative division codes, and can be directly used as the digital coding of the existing digital serial numbers.

the address part rule sequentially comprises a province-city-county part, a street part, a district part, a building part, a unit part and a room part; for each address part rule, the numerical coding rules are respectively: the province, city, district and county part uses the administrative division number as a digital code; the street part is used for coding different streets in sequence according to the natural number sequence by using two digits in the same province-city-county area; a cell part, in the same street area, using two digits to code different cells in turn according to the natural number sequence; the building number part uses the three-digit building number as a digital code in the same cell; the unit part uses the one-digit unit number as a digital code in the same building; the room part, within the same unit, uses its four digit room number as a numeric code.
Wherein building numbers, unit numbers and room numbers refer to numbers set by a developer or a property management organization of a cell for the building, unit, room when building or managing the cell.
FIG. 4 is a schematic diagram of one embodiment of formulating address encoding rules, as shown in FIG. 2, the address portion rule being divided into a provincial and county portion, a street portion, a cell portion, a building portion, a unit portion, and a room portion in that order. The digital coding rule is that administrative division coding is adopted in province, city, county and county parts, two-bit street coding is adopted in street parts, two-bit cell coding is adopted in cell parts, three-bit building number coding is adopted in building number parts, one-bit unit number coding is adopted in unit parts, and four-bit room number coding is adopted in room parts.
(72) And (3) performing Chinese word segmentation on the specific practical standard address description obtained in the step (7) to obtain a plurality of address parts. The area ranges of the plurality of address portions are respectively in one-to-one correspondence with the area ranges of the address portion rule in step (71). That is, with the address part rule, the real address is also divided into a province-city-county part, a street part, a cell part, a building part, a unit part, and a room part.
(73) According to the address encoding rule of step (71), a plurality of address parts are sequentially converted into digital codes.
FIG. 5 is a schematic diagram of one embodiment of encoding addresses. As shown in fig. 5, in the present embodiment, the plurality of address portions and their digital codes are sequentially: the province-city-county part is specifically a non-tin city-benefit mountain area of Jiangsu province, and the administrative division code is 320206; the part of the street is a bridge street, two-bit street codes are used, namely, all streets in the Wuxi city, huishan area of Jiangsu province are sequentially coded by using natural numbers of two-bit numbers, and then the bridge street is coded as 01; the cell part is a multi-land cell, two-bit cell coding is used, namely, all cells in a weir bridge street are sequentially coded by using two natural numbers, and the multi-land cell is coded into 11; the building number part is 100 numbers, three building number codes are used, and building numbers appointed by cell developers or property management companies can be directly used as codes, so that the building numbers are coded into 100; the unit part is 1 unit, using one-bit unit number code, and directly using the unit number specified by the cell developer or property management company as code, then the unit is coded as 1; the room part is 1808 room, using four-digit room number code, the room number can be directly used as code, which is designated by the cell developer or property management company, and then the room number is coded 1808. Finally, the codes of the room No. 1 unit 1808 of the Wei bridge street compound district 100 in Jiangsu province, wuxi city, mountain area are: 320206011110011808. the digital codes are used as address information of clients to be stored, so that the operation of a computer is more convenient.
It can also be seen from the embodiment shown in fig. 5 that in the address description, the description of the address parts of the low level, in particular the building number part, the unit part and the room number part, are directly described using numerals in the common general knowledge, so that no irregular description will occur substantially. The descriptions of the high-level address parts, such as province and city county parts, street parts and the like, are all descriptions by using words, and phenomena such as incomplete words, aliases, different description modes and the like are easy to occur. In the method of converting a non-canonical address into a canonical address of the present invention, therefore, the non-canonical address description is divided into a first front-section description and a back-section description, and then conversion is performed only for the first front-section description.
The above description is illustrative of the invention and not limiting, the scope of the invention being defined by the appended claims, which may be modified in any manner without departing from the basic structure of the invention.
