Description
Technical Field
The present application relates to the field of address processing technologies, and in particular, to an address standardization processing method and device.
Background
In the logistics industry, the mailing address and the receiving address of goods to be shipped are of critical importance, which identify where the goods are coming from and where they are going to be shipped.
In the related technology, after receiving goods mailed by a client, an express company inputs a mailing address and a receiving address of the goods into a logistics system through code scanning, the logistics system judges the quantity of the goods sent from one place to another according to the mailing address and the receiving address, and then the express company arranges express vehicles according to the quantity of the goods. Due to different cognitive habits of customers on addresses and different address describing modes, a large number of addresses which are not described in standard and clear exist in a logistics system. Some addresses comprise province, city, county/district and detailed addresses, and some addresses comprise province, county/district and detailed addresses; for example, the address of the golden aster No. 3 of Fugou county of Zhou city, Henan and the address of the golden aster No. 3 of Fugou county, Henan represent the same place, but the latter lacks of Zhou city. Some addresses are full names of provinces and urban districts, and some addresses are short names, for example, the full name address is the Fugou county of Zhou city in Henan province, and the short name address is the Fugou county of Zhou city in Henan province. Some addresses are addresses before administrative districts of city counties are re-divided, for example, the original fir yang county of the Anhui province Anqing city is divided into Anhui province copper tomb cities, but some customers do not know that the addresses are still the fir yang counties of the Anhui province Anhui city when writing the addresses. The logistics system is enabled to have larger errors when judging the quantity of goods sent from one place to another according to the recorded sending address and receiving address, so that the vehicle routing planning is improper, and the logistics cost and the time cost are increased.

Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of methods and apparatus consistent with certain aspects of the present application, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating an address normalization processing method according to an exemplary embodiment.
As shown in fig. 1, the address normalization processing method provided in this embodiment includes the following steps:
step S11, acquiring an initial address;
step S12, preprocessing the initial address to obtain a preprocessed address;
in this step, since the obtained initial address may include punctuation marks such as pause marks, commas, and spaces, the initial address needs to be preprocessed, that is, the punctuation marks and the spaces are deleted, so as to obtain an address only containing chinese characters.
Step S13, extracting at least one address name recorded in a normalized address information base from the preprocessed addresses, where the normalized address information base is pre-established, the normalized address information base records standard names and level information of each level of national addresses and alias names of each level of addresses, and each level of addresses includes: the system comprises provincial-level addresses, city-level addresses and prefecture-level addresses, wherein the level information is used for indicating the superior-inferior relation of the addresses of all levels;
for example, shanghai 1-shanghai city 11-qingpu district (qingpu) 111, where "shanghai" is a provincial address, "shanghai" is a city-level address, "qingpu district" is a district-level address, and "qingpu" is an alias name of the district-level address "qingpu district"; "1", "11", and "111" are level information, "1" is used to indicate "shanghai" as a provincial address, "11" is used to indicate "shanghai city" as a city-level address, "111" is used to indicate "kups district (kups)" as a prefecture-level address, and "1" indicates an upper level of "11" and "11" indicates an upper level of "111".
Step S14, determining the address name of the lowest level among the extracted address names according to the level information corresponding to the extracted address names, and determining the standard name of at least one level address corresponding to the address name of the lowest level according to the normalized address information base;
since at least one address name extracted in the preprocessed address in step S13 is already recorded in the normalized address information base, the level information corresponding to the address name can be found in the normalized address information base by the extracted address name.
For example, at least one address name extracted from the preprocessed addresses is shanghai-qingpu, the level information corresponding to the shanghai is determined to be "1" and the level information corresponding to the qingpu is determined to be "111" according to the normalized address information base, and the address corresponding to the "111" is determined to be a county-level address, that is, the address name of the lowest level, that is, the name of the county-level address according to the level information; however, according to the normalized address information base, it is possible to determine a standard name of the prefecture-level address as "Qingpu district", then determine a standard name of an address whose previous level address is "11", i.e., the city-level address "Shanghai city", according to the level information "111", and then determine a standard name of an address whose previous level address is "1", i.e., the provincial address "Shanghai", according to "11"; thus, the standard name of at least one level of address is obtained: Shanghai-Shanghai City-Qingpu district.
Step S15, using the standard name of at least one level address corresponding to the lowest level address name as the address after the standardization process of the initial address, and outputting the address after the standardization process.
In the embodiment, the initial address is obtained; preprocessing the initial address to obtain a preprocessed address; extracting at least one address name recorded in a normalized address information base from the preprocessed addresses, wherein the normalized address information base is established in advance; because the standardized address information base records the standard name and the level information of each level of the national address and the alias name of each level of the national address, each level of the national address comprises: the system comprises provincial-level addresses, city-level addresses and prefecture-level addresses, wherein the level information is used for indicating the superior-inferior relation of the addresses of all levels; thus, the address name of the lowest level among the extracted address names can be determined based on the level information corresponding to the extracted address names; then, determining the standard name of at least one level address corresponding to the address name of the lowest level according to the normalized address information base; and taking the standard name of at least one level address corresponding to the address name of the lowest level as the address of the initial address after the standardization processing, and outputting the address after the standardization processing. By the method, whether different names exist in the initial, whether city-level address names are wrongly written or not or whether the attributive regions are wrongly written or not can be used, the national provincial address standard name, the city-level address standard name and the standard name of the district-level address can be extracted from the initial address, and the quantity of goods sent from one region to another region can be accurately obtained from massive addresses, so that vehicle routing can be optimized, and logistics cost and time cost are greatly reduced.
Further, the preprocessing the initial address includes:
and deleting punctuation marks and spaces in the initial address.
Further, the extracting, from the preprocessed addresses, at least one address name recorded in a normalized address information base includes:
extracting a first address name from the preprocessed address;
after extracting a first address name, if the address name recorded in a normalized address information base cannot be extracted again from the preprocessed address, determining the first address name as the extracted address name; alternatively, the first and second electrodes may be,
after extracting a first address name, a second address name can be extracted from the preprocessed address, and if the second address name is a county-level address, the first address name and the second address name are determined as the extracted address name; alternatively, the first and second electrodes may be,
after extracting a first address name, a second address name can be extracted from the preprocessed address, and if the second address name is not a district-level address and a third address name can be extracted from the preprocessed address, the first address name, the second address name, and the third address name are determined as the extracted address names;
the first address name, the second address name and the third address name are all address names recorded in a normalized address information base, the first address name is a superior address of the second address name, and the second address name is a superior address of the third address name.
For example, the address after the preprocessing is "houbei province baoding city competitive show area", and the record in the normalized address information base is "houbei province (houbei) 2-baoding city (baoding) 22-competitive show area (competitive show) 222", where "houbei province", "baoding city" and "competitive show area" are respectively the standard names of provincial level address, city level address and district level address, and "houbei", "baoding" and "competitive show" are respectively the alias names of provincial level address, city level address and district level address, and "2", "22" and "222" respectively represent provincial level address, city level address and district level address. When the first extracted address name is "north river", the "north river" is an alias name of a provincial address and is recorded in the normalized address information base, but the provincial address name recorded in the normalized address information base, namely the "north river province", can be extracted again from the preprocessed address, and then the "north river province" is determined as the extracted address name. Then, after the 'Hebei province' is extracted, the name of a second address, namely 'baoding city', can be extracted from the preprocessed address, after the 'baoding city' is judged not to be a county-level address, the name of a third address, namely 'competitive show district', can be extracted continuously, and finally the 'Hebei province-baoding city-competitive show district' is determined to be the extracted address name.
For another example, the address after the preprocessing is the "competitive show area in Hebei province", the first address name "Hebei province" and the second address name "competitive show area" are extracted from the address, and since the "competitive show area" is a county-level address, the third address name does not need to be extracted, and the "Hebei province-competitive show area" is directly determined as the extracted address name.
Further, the extracting the first address name from the preprocessed address includes:
extracting a first group of characters according to a first extraction length from a first starting point of the preprocessed address, wherein the position of the first starting point and the first extraction length are both updatable values, the initial position of the first starting point is the position of a first character of the preprocessed address, the end position of the first starting point is the position of a last character of the preprocessed address, and the minimum value, the step value and the maximum value of the first extraction length are preset values;
and when the first group of characters is the address name recorded in the normalized address information base, determining the first group of characters as the first address name.
Wherein the minimum value of the first extraction length is 1, the step value is 1, and the maximum value is 12.
For example, the address after preprocessing is "facing yang in beijing city", and it is recorded as "beijing 3-beijing city 33-facing yang district (facing yang) 333" in the normalized address information base. Starting a first extraction length of 1, and extracting a character from a first north character to obtain north, wherein the north is not an address name recorded in a normalized address information base; therefore, the first extraction length is increased by 1 to become 2, and two words "beijing", which are address names recorded in the normalized address information base, are extracted from the first "north" word, and thus "beijing" is determined as the first address name.
Further, the extracting, from the preprocessed addresses, at least one address name recorded in a normalized address information base further includes:
extracting a second group of characters according to a second extraction length from a second starting point of the preprocessed address, wherein the position of the second starting point and the second extraction length are updatable values, the initial position of the second starting point is the position of the next character of the first address name, the end position of the second starting point is the position of the last character of the preprocessed address, and the minimum value, the step value and the maximum value of the second extraction length are preset values;
and when the second group of characters are address names recorded in a normalized address information base and the first address name is determined to be the upper address of the second group of characters according to the normalized address information base, determining the second group of characters as the second address name.
Wherein the minimum value of the second extraction length is 1, the step value is 1, and the maximum value is 12.
For example, the address after preprocessing is "facing yang in beijing", and the first address name extracted is "beijing". At the beginning, the second extraction length is 1, then the second start point position is the position of "north" after the first address name "beijing", one character "north" is extracted, which is not the address name recorded in the normalized address information base, then the second extraction length is added by 1, two characters "beijing" are extracted again from the "north" character, which is the address name recorded in the normalized address information base, but the level information corresponding to the first address name "beijing" is all "3", then the first address name "beijing" is not the upper level address of the second group character "beijing", therefore, the second extraction length is added by 1, three characters are extracted again, the second group character "beijing city" is obtained again, which is the address name recorded in the normalized address information base, and the level information corresponding to the second group character is "33", so that the determination can be made, the first address name "beijing" is an upper-level address name of the second group character "beijing city", and therefore, the second group character "beijing city" is determined as the second address name.
Further, the extracting, from the preprocessed addresses, at least one address name recorded in a normalized address information base further includes:
extracting a third group of characters according to a third extraction length from a third starting point of the preprocessed address, wherein the position of the third starting point and the third extraction length are updatable values, the initial position of the third starting point is the position of a character next to the name of the second address, the end position of the third starting point is the position of the last character of the preprocessed address, and the minimum value, the stepping value and the maximum value of the third extraction length are preset values;
and when the third group of characters are address names recorded in a normalized address information base and the second address name is determined to be the upper address of the third group of characters according to the normalized address information base, determining the third group of characters as the third address name.
Wherein the minimum value of the third extraction length is 1, the step value is 1, and the maximum value is 12.
For example, the preprocessed address is "beijing city facing yang", the first address name "beijing" and the second address name "beijing city" are extracted, and the second address name "beijing city" is not a district-level address name, so that a third address name may be extracted.
Specifically, one character "heading" is extracted as a third group of characters starting from the position "heading" of the next character of the second address name "beijing city", which is not an address name recorded in the normalized address information base, and then the third extraction length is increased by 1, two characters "heading for the sun" are extracted as a third group of characters starting from the "heading" character, which is an address name already recorded in the normalized address information base, and the level information corresponding to the third group of characters "heading for the sun" is "333", whereby it can be determined that the second address name "beijing city" is an upper-level address name of the third group of characters "heading for the sun", and therefore, the third group of characters "heading for the sun" can be determined as the third address name.
It should be noted that before determining the second address name and the third address name, it is necessary to determine whether the first address name is an upper level name of the second group of characters, determine the second group of characters as the second address name when the first address name is the upper level name of the second group of characters, determine whether the second address name is the upper level address name of the third group of characters, and determine the third group of characters as the third address name when the second address name is the upper level address name of the third group of characters. The purpose is to ensure the accuracy of the standard name of at least one level of address finally output. For example, two addresses of "Heilongjiang province (Heilongjiang) 4-peony river city (peony river) 44-Xian district (Xian) 444" and "Shaanxi province (Shaanxi) 5-Xian city (Xian) 55", a district-county address of the Heilongjiang province "Xian" and a city-level address of the Shaanxi province are duplicate names, if the first address name in the address of the Xian district of the peony river city of the Heilongjiang province is extracted as "Heilongjiang province", the second address name is "peony river city", and the third address name is "Xian", then if the address name of the peony river city is not determined to be "Xian" address name of the Xian ", the most probable third address name of the Xian" is extracted as a superior address of the Shaanxi province. Therefore, only if the upper-level and lower-level relations are determined, the accurate standard name of the three-level address corresponding to the initial address can be finally obtained. When the extracted second address name "peony river city" is not the upper address of the third address name "xi ' and the third extraction length is updated according to the step value, that is, the third extraction length is extracted again after 1 is added to obtain the third group of characters" xi ' an area ", and then whether the second address name" peony river city "is the upper address name of the" xi ' an area "is judged again to obtain the accurate address name finally.
Further, the determining a standard name of the at least one level address corresponding to the address name of the lowest level according to the normalized address information base includes:
when the address name of the lowest level is a district-county level address, obtaining a standard name of the district-county level address corresponding to the address name of the lowest level, a standard name of a city-level address corresponding to the address name of the lowest level and a standard name of a provincial level address corresponding to the address name of the lowest level according to the normalized address information base; alternatively, the first and second electrodes may be,
when the address name of the lowest level is a city address, obtaining a standard name of the city address corresponding to the address name of the lowest level and a standard name of a provincial address corresponding to the address name of the lowest level according to the normalized address information base; alternatively, the first and second electrodes may be,
and when the address name of the lowest level is a provincial address, obtaining a standard name of the provincial address corresponding to the address name of the lowest level according to the normalized address information base.
For example, at least one address name extracted from the preprocessed addresses is "shanghai-kups", the level information corresponding to "shanghai" can be determined as "1" and the level information corresponding to "kups" is "111" according to the normalized address information base, and the address corresponding to "111" can be determined as a prefecture-level address, that is, the lowest-level address name, that is, the "kups" is a prefecture-level address name according to the level information; however, according to the normalized address information base, it is possible to determine a standard name of the prefecture-level address as "Qingpu district", then determine a standard name of an address whose previous level address is "11", i.e., the city-level address "Shanghai city", according to the level information "111", and then determine a standard name of an address whose previous level address is "1", i.e., the provincial address "Shanghai", according to "11"; thus, the standard name of at least one level of address is obtained: Shanghai-Shanghai City-Qingpu district.
Further, the level information is digital information, wherein the number of digits of the level information corresponding to the lower address is greater than the number of digits of the level information corresponding to the upper address, and the level information corresponding to the lower address includes the level information corresponding to the upper address.
For example, shanghai 1-shanghai city 11-qingpu district (qingpu) 111, where "shanghai" is a provincial address, "shanghai" is a city-level address, "qingpu district" is a district-level address, and "qingpu" is an alias name of the district-level address "qingpu district"; "1", "11", and "111" are level information, "1" is used to indicate "shanghai" as a provincial address, "11" is used to indicate "shanghai city" as a city-level address, "111" is used to indicate "kups district (kups)" as a prefecture-level address, and "1" indicates an upper level of "11" and "11" indicates an upper level of "111".
It is understood that the level information may also be alphabetical information, such as "A-AA-AAA"; where "A" may be used to represent a provincial address, "AA" may represent a city-level address, and "AAA" may represent a prefecture-level address.
