[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0040] To make the description of this disclosure more detailed and complete, illustrative descriptions of embodiments and specific examples of the present invention are provided below; however, these are not the only forms of implementing or utilizing the specific embodiments of the present invention. The embodiments cover features of multiple specific embodiments and the methods, steps, and their order for constructing and operating these specific embodiments. However, other specific embodiments may also be used to achieve the same or equivalent functions and step sequences. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.
[0041] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in sequences other than those illustrated or described herein.
[0042] Example 1
[0043] like Figure 1The diagram shown is a flowchart illustrating an administrative address extraction method provided in an embodiment of the present invention. This administrative address extraction method includes the following steps:
[0044] Step S101: Obtain the sequence of administrative address elements obtained by matching the current address to be extracted with preset address elements, wherein the sequence of administrative address elements includes several administrative address elements arranged in matching order, and the administrative address elements include administrative address name and administrative address code;
[0045] The above-mentioned address to be extracted is the address input by the user. Regarding the specific implementation of the above-mentioned address to be extracted, such as format, completeness, and number of addresses contained, the embodiments of the present invention do not impose any limitations.
[0046] The above-mentioned administrative address names and administrative address codes conform to the national standards for administrative divisions and administrative division codes. For example, the above-mentioned administrative address name can be "Guangdong Province" or "Bao'an District"; the administrative address code corresponding to the above-mentioned administrative address name "Bao'an District" is "440306000000".
[0047] The aforementioned administrative address element includes an administrative address name and an administrative address code. The specific implementation of the aforementioned administrative address element can be set according to the specific implementation scenario. This embodiment of the invention does not impose any limitations on this. For example, the aforementioned administrative address element can be "(administrative address name 1, administrative address code 1)", such as "(Bao'an District, 440306000000)"; or "administrative address name 1 administrative address code 1", such as "Bao'an District 440306000000", etc.
[0048] The specific implementation of the above-mentioned administrative address element sequence can be specifically set according to the specific implementation of the above-mentioned administrative address element. For example, the form of the above-mentioned administrative address element sequence can be "(administrative address name 1, administrative address code 1), (administrative address name 2, administrative address code 2)...", where "(administrative address name 1, administrative address code 1)" is an administrative address element.
[0049] It should be noted that the above administrative address element sequence may include not only administrative address elements related to the fourth-level administrative address, but also other address names unrelated to the fourth-level administrative address. However, these other address names do not have corresponding address codes. For example, the above administrative address element sequence could be "(Administrative Address Name 1, Administrative Address Code 1), (Administrative Address Name 2, Administrative Address Code 2), (Administrative Address Name 3, Administrative Address Code 3), (Administrative Address Name 4, Administrative Address Code 4), Other Address Names".
[0050] Step S102: When it is determined that multiple or one administrative address needs to be extracted, the administrative address element sequence is split or deleted according to the administrative address code to obtain a new administrative address element sequence.
[0051] The embodiments of the present invention do not limit the specific implementation of the above-described method for determining and extracting multiple or one administrative addresses. Any implementation method that can determine and extract multiple or one administrative addresses can be applied to the embodiments of the present invention. For example, multiple or one administrative addresses can be determined and extracted by responding to instructions, identifying whether there are multiple administrative addresses by text recognition, or according to preset requirements.
[0052] The aforementioned administrative address elements can form one or more administrative addresses.
[0053] Implementation Method 1: When determining to extract multiple administrative addresses, the administrative address element sequence is split according to the aforementioned administrative address codes to obtain one or more new administrative address element sequences. For example, if the aforementioned administrative address elements include "Guangdong Province, Bao'an District", the administrative address element sequence is split to obtain a new administrative address element sequence of "Guangdong Province, Bao'an District". Similarly, if the aforementioned administrative address elements include "Guangdong Province, Bao'an District, Beijing, Chaoyang District", the administrative address element sequence is split to obtain two new administrative address element sequences: "Guangdong Province, Bao'an District" and "Beijing, Chaoyang District".
[0054] The above-mentioned determination to extract multiple administrative addresses refers to processing the above-mentioned administrative address element sequence for the purpose of extracting multiple administrative addresses, and does not guarantee that multiple new administrative address element sequences will be obtained.
[0055] In the above description of the implementation method, the administrative address codes of all administrative address elements are omitted, and only the administrative address names are used to replace the administrative address elements. The same substitution method may appear in the following description. It is only an abbreviation for the convenience of expression and does not represent a limitation on the administrative address elements. It will not be repeated hereafter.
[0056] It should be noted that the above-mentioned splitting of administrative address elements is to split administrative address elements from the original sequence of administrative address elements into a new sequence of administrative address elements, rather than splitting the internal composition of administrative address elements.
[0057] Implementation Method 2: When determining to extract an administrative address, based on the aforementioned administrative address code, the administrative address element sequence is processed by deleting administrative address elements to obtain a new administrative address element sequence. For example, if the aforementioned administrative address elements include "Guangdong Province, Bao'an District, Beijing, Chaoyang District", then "Guangdong Province, Bao'an District" can be deleted to obtain a new administrative address element sequence of "Beijing, Chaoyang District"; alternatively, "Beijing, Chaoyang District" can be deleted to obtain a new administrative address element sequence of "Guangdong Province, Bao'an District".
[0058] Step S103: Determine the administrative level four address corresponding to the new administrative address element sequence according to the preset address element extraction logic.
[0059] The embodiments of the present invention do not limit the specific implementation of the above-mentioned address element extraction logic. Any implementation of the address element extraction logic that can extract the fourth-level administrative address can be applied to the embodiments of the present invention. For example, the deletion processing logic, the filtering processing logic, the merging processing logic, the sorting position of the administrative address element in the administrative address element sequence, etc.
[0060] As an optional implementation method, determining the administrative level four address corresponding to the above-mentioned new administrative address element sequence includes:
[0061] Output the administrative address names of the administrative address elements in the new sequence of administrative address elements according to their sorting positions, and associate them with the administrative division levels respectively;
[0062] The administrative address code of the last administrative address element in the new administrative address element sequence is retained.
[0063] The aforementioned Level 4 administrative addresses conform to the national administrative division standards, including at least one of the four administrative division levels: province, city, district / county, and town / township / street, as well as the administrative address code corresponding to the lowest administrative division level. For example, a Level 4 administrative address includes: 'Province': 'Guangdong Province', 'City': 'Shenzhen City', 'District': 'Bao'an District', 'adcode': '440306000000', where the adcode is the administrative address code.
[0064] It should be noted that when determining to extract multiple administrative addresses, the final number of administrative level 4 addresses obtained is consistent with the number of new administrative address element sequences obtained; when determining to extract only one administrative address, a final administrative level 4 address is obtained.
[0065] The embodiments of the present invention can meet the needs of extracting one or more administrative level 4 addresses in different scenarios, improve the accuracy of extracting administrative level 4 addresses, and ensure the timeliness and accuracy of logistics.
[0066] It should be noted that the embodiments of the present invention do not limit the specific implementation of the above-mentioned method of obtaining the administrative address element sequence by matching the preset address elements of the current address to be extracted. Any implementation method that can obtain the above-mentioned administrative element sequence can be applied to the embodiments of the present invention, such as trie, administrative address database matching, etc.
[0067] As an optional implementation, the above-mentioned method of obtaining an administrative address element sequence by matching preset address elements of the current address to be extracted includes:
[0068] Construct an address dictionary that includes administrative level four address information; the administrative level four address information includes administrative address code, administrative address name, and address latitude and longitude information.
[0069] In some implementation scenarios, information such as the administrative address name, and / or administrative address affiliation, and / or administrative address level, and / or administrative address code of a Level 4 administrative address may change. By constructing an address dictionary for Level 4 administrative addresses, the address dictionary can be directly modified in implementation scenarios where the aforementioned Level 4 administrative address information changes. This facilitates rapid maintenance of Level 4 administrative address information and avoids errors in Level 4 administrative address extraction due to failure to respond promptly to updates.
[0070] Based on the address dictionary, construct an address information object (addressInfo) that includes the above-mentioned administrative level four address information, and construct an AC automaton dictionary tree;
[0071] In constructing the AC automaton dictionary tree, the abbreviation and full name of the administrative address name are determined. The abbreviation and full name of the administrative address name are used as words to construct the AC automaton dictionary tree. The words corresponding to the abbreviation and full name of the administrative address name of the same administrative address are set to point to the same address information object.
[0072] Using administrative address names to determine the abbreviation and full name, such as the full name of Beijing Municipality being Beijing Municipality and the abbreviation being Beijing; and the full name of Xinjiang Uygur Autonomous Region being Xinjiang Uygur Autonomous Region and the abbreviation being Xinjiang, can improve the accuracy of matching administrative addresses at the fourth level.
[0073] The administrative level 4 address information in the AC automaton trie is used as a preset address element; the preset address element is matched against the current address to be extracted; if the text in the AC automaton trie matches the word, the matched word and the attributes of the corresponding address information object are returned; the attributes include administrative address code, administrative address name, address longitude, address latitude, and administrative address level; based on the returned word and address information object, the administrative address name and administrative address code of the address are parsed and returned as the administrative address element sequence.
[0074] In some embodiments, when determining to extract multiple administrative addresses, the administrative address element sequence is split into administrative address elements according to the aforementioned administrative address code, including:
[0075] Determine the hierarchical relationship between the above administrative address elements, and split the administrative address elements that have a hierarchical relationship and are arranged in adjacent positions into the same administrative address element sequence.
[0076] In one specific embodiment, when determining to extract multiple administrative addresses, the hierarchical relationship between the aforementioned administrative address elements is determined, that is, the hierarchical relationship between the administrative address names among the aforementioned administrative address elements is determined. If there is a hierarchical relationship between the multiple administrative address elements and their sorting positions are adjacent, then these administrative address elements are split into the same administrative address element sequence; if the aforementioned administrative address elements contain multiple non-hierarchical administrative address elements, then the multiple non-hierarchical administrative address elements are split into different administrative address element sequences respectively.
[0077] If multiple administrative address elements have a subordinate relationship in terms of administrative division, that is, the first administrative address element belongs to or is subordinate to the second administrative address element, for example, Shenzhen belongs to Guangdong Province, or Guangdong Province is subordinate to Shenzhen, or multiple administrative address elements are the same, for example, two administrative address elements are both Shenzhen, then there is a subordinate relationship between the above multiple administrative address elements, which will not be elaborated further.
[0078] Specifically, the numbers at different positions in the above-mentioned administrative address codes represent administrative addresses at different administrative division levels. If the numbers at the positions representing administrative addresses at the same administrative division level are the same in the administrative address codes of several administrative address elements, it is determined that the above-mentioned administrative address elements have a subordinate relationship, which will not be elaborated further.
[0079] As one implementation method, the aforementioned administrative address elements include "Guangdong Province, Bao'an District, Beijing, Chaoyang District". When determining to extract multiple administrative addresses, the aforementioned administrative address element sequence is split into administrative address elements to obtain a first new administrative address element sequence including "Guangdong Province, Bao'an District" and a second new administrative address element sequence including "Beijing, Chaoyang District".
[0080] As another implementation method, the aforementioned administrative address elements include "Beijing, Guangdong, Shenzhen, Bao'an District, Hangcheng Subdistrict, Beijing, Chaoyang District". When determining to extract multiple administrative addresses, the above administrative address element sequence is split into administrative address elements to obtain a third new administrative address element sequence including "Beijing", a fourth new administrative address element sequence including "Guangdong, Shenzhen, Bao'an District, Hangcheng Subdistrict", and a fifth new administrative address element sequence including "Beijing, Chaoyang District".
[0081] In this embodiment of the invention, administrative address elements that have a subordinate relationship and are arranged in adjacent positions in the above-mentioned administrative address element sequence are split into the same administrative address element sequence, which can accurately extract multiple administrative addresses.
[0082] In some embodiments, when determining to extract an administrative address, administrative address element deletion processing is performed on the administrative address element sequence based on the aforementioned administrative address code, including:
[0083] Determine the hierarchical relationship between the above administrative address elements, and delete the administrative address elements in the above administrative address element sequence that do not have a hierarchical relationship with the administrative address element that is first in the sequence.
[0084] In one specific embodiment, when determining the extraction of an administrative address, the hierarchical relationship between the aforementioned administrative address elements, that is, the hierarchical relationship between the administrative address names among the aforementioned administrative address elements, is considered. If, in the sequence of administrative address elements, there exists an administrative address element that does not have a hierarchical relationship with the administrative address element in the first position of the sequence, then that administrative address element is deleted.
[0085] As one implementation method, the aforementioned administrative address elements include "Guangdong Province, Beijing, Bao'an District". When determining to extract an administrative address, the aforementioned administrative address elements are deleted. Among the aforementioned administrative address elements, the first administrative address name is Guangdong Province, and the second administrative address name is Beijing. Since Beijing is not subordinate to Guangdong Province, this administrative address element is deleted, resulting in a new sequence of administrative address elements, which includes "Guangdong Province, Bao'an District".
[0086] This invention eliminates interfering administrative address elements in the above-mentioned administrative address element sequence by deleting administrative address elements that do not have a subordinate relationship with the administrative address element in the first position of the sequence.
[0087] In some embodiments, the administrative level four address corresponding to the new administrative address element sequence is determined according to a preset address element extraction logic, including:
[0088] Based on the above administrative address names, several administrative address elements in the above new administrative address element sequence that have character inclusion relationships and are arranged in adjacent positions are filtered out, and the administrative address element with the most characters in its administrative address name is retained.
[0089] Based on the newly filtered sequence of administrative address elements, the corresponding fourth-level administrative address is determined.
[0090] It should be noted that the above character inclusion relationship may include administrative division levels that are not included. For example, "Hongjiang City" and "Hongjiang Management District". Although "Hongjiang Management District" does not include the administrative division level "city" of "Hongjiang City", there is still a character inclusion relationship.
[0091] As one implementation method, if the new administrative address element sequence includes "Hunan Province, Huaihua City, Hongjiang City, Hongjiang Management District, Xinjie Subdistrict", and "Hongjiang City" and "Hongjiang Management District" in the new administrative address element sequence have a character inclusion relationship and are arranged in adjacent positions, then the administrative address element with the most characters in the address name is taken, that is, "Hongjiang Management District" is retained. Then the corresponding fourth-level administrative address can include 'Province': 'Hunan Province', 'City': 'Huaihua City', 'District': 'Hongjiang Management District', 'Town': 'Xinjie Subdistrict'.
[0092] This invention improves the accuracy of extracting fourth-level administrative addresses by retaining the administrative address element with the most characters in the administrative address name.
[0093] In some embodiments, the administrative level four address corresponding to the new administrative address element sequence is determined according to a preset address element extraction logic, including:
[0094] Based on the administrative address level determined by the above administrative address code, administrative address elements in the above new administrative address element sequence that have a higher administrative address level than the administrative address element that appears earlier in the sequence are deleted.
[0095] Based on the newly generated sequence of administrative address elements after deletion, the corresponding fourth-level administrative address is determined.
[0096] As an optional implementation, the aforementioned administrative address level is determined by the aforementioned administrative address code. Different positions of the digits in the aforementioned administrative address code represent administrative addresses at different administrative division levels. If a position is filled with 0, it indicates that an administrative address at that administrative division level does not exist. For example, an administrative address code ending with 10 zeros corresponds to an administrative address level of 0, representing an administrative division level of province or municipality; ending with 8 zeros corresponds to an administrative address level of 1, representing an administrative division level of prefecture-level city; ending with 6 zeros corresponds to an administrative address level of 2, representing an administrative division level of county-level city, county, or district; and ending with other digits corresponds to an administrative address level of 3, representing an administrative division level of town, township, or street.
[0097] As one implementation method, if the new administrative address element sequence includes "Guangdong Province, Bao'an District, Shenzhen City", in which the first administrative address name is Guangdong Province, the second administrative address name is Bao'an District, and the third administrative address name is Shenzhen City, and Shenzhen City has a higher administrative address level than Bao'an District, and Shenzhen City is deleted, then the corresponding fourth-level administrative address can include 'Province': 'Guangdong Province', 'District': 'Bao'an District'.
[0098] In this embodiment of the invention, by deleting administrative address elements with higher administrative address levels than the preceding administrative address elements in the new administrative address element sequence, the resulting corresponding administrative level four addresses can be sorted according to administrative address level, which is beneficial to the accuracy of logistics delivery.
[0099] In some embodiments, the administrative level four address corresponding to the new administrative address element sequence is determined according to a preset address element extraction logic, including:
[0100] Based on the above administrative address names, administrative address elements with the same administrative address name and adjacent positions in the above new administrative address element sequence are merged.
[0101] Based on the newly merged sequence of administrative address elements, the corresponding fourth-level administrative address is determined.
[0102] It should be noted that the embodiments of the present invention do not limit the number of the above-mentioned adjacent administrative address elements, which can be two or more.
[0103] As one implementation method, if the new administrative address element sequence includes "Beijing, Beijing, Beijing, Chaoyang District, Chaoyang District, Wangjing Subdistrict", then administrative address elements with the same administrative address name and adjacent positions in the above new administrative address element sequence are merged. Several Beijings are merged into one until the next different administrative address name "Chaoyang District" appears. Similarly, several Chaoyang Districts are merged into one until the next different administrative address name "Wangjing Subdistrict" appears. The corresponding fourth-level administrative address can include 'Province': 'Beijing', 'City': 'Beijing', 'District': 'Chaoyang District', 'Town': 'Wangjing Subdistrict'.
[0104] This invention avoids duplication of administrative address names in the fourth-level administrative address by merging administrative address elements with the same name and adjacent positions in the new administrative address element sequence.
[0105] It should be noted that the address element filtering logic, address element deletion logic, and address element merging logic in the above-described embodiments can be combined in specific ways according to the specific implementation situation to obtain more embodiments. The present invention does not impose any limitation on the number or order of the combined logic.
[0106] As another implementation method, if the administrative address element sequence includes "Guangdong Province, Shenzhen City, Bao'an District, Beijing City, Beijing City, Chaoyang District", when extracting multiple administrative addresses from the administrative address element sequence, the hierarchical relationship between several administrative address elements in the above administrative address element sequence is determined, and administrative address elements with hierarchical relationship and adjacent positions in the above administrative address element sequence are split into the same administrative address element sequence, thus obtaining a new administrative address element sequence "Guangdong Province, Shenzhen City, Bao'an District" and another new administrative address element sequence "Beijing City, Beijing City, Chaoyang District". In "Beijing City, Beijing City, Chaoyang District", administrative address elements with the same administrative address name and adjacent positions are merged, then the two Beijing cities are merged into one, and the new administrative address element sequence "Beijing City, Beijing City, Chaoyang District" can be represented by the following fourth-level administrative address: 'Province': 'Beijing', 'City': 'Beijing City', 'District': 'Chaoyang District'.
[0107] In some embodiments, the process of determining the corresponding administrative level four address further includes:
[0108] The aforementioned administrative address elements also include administrative address levels;
[0109] In the newly processed sequence of administrative address elements, retain the administrative address code of the lowest-ranking administrative address element, and use this administrative address code to complete the administrative address elements that appear earlier in the sequence.
[0110] As an optional implementation, the administrative address name of the administrative address element that appears first in the sequence is completed based on the administrative address code.
[0111] The numbers in different positions of the above administrative address codes represent administrative addresses at different administrative division levels. Therefore, the administrative address elements that appear first in the sequence can be completed based on the administrative address codes.
[0112] The processed new administrative address element sequence can be a sequence of new administrative address elements after filtering, or a sequence of new administrative address elements after deletion, or a sequence of new administrative address elements after merging, or a sequence of new administrative address elements after any two of the above processing methods, or a sequence of new administrative address elements after all three of the above processing methods.
[0113] As one implementation method, if the processed new administrative address element sequence includes "(Guangdong Province, 440000000000), (Bao'an District, 440306000000)", retaining the administrative address code of the lowest administrative address level administrative address element, then the above new administrative address element sequence becomes "Guangdong Province, Bao'an District, 440306000000". Based on the administrative address code 440306000000 corresponding to Bao'an District, the administrative address element at the beginning of the sequence is completed, then the above new administrative address element sequence becomes "Guangdong Province, Shenzhen City, Bao'an District, 440306000000". The corresponding fourth-level administrative address includes 'Province': 'Guangdong Province', 'City': 'Shenzhen City', 'District': 'Bao'an District', 'adcode': '440306000000'.
[0114] As another implementation, null characters are used to supplement the other administrative address names of the above-mentioned administrative level four address. That is, if a certain administrative level four address includes 'province': 'Guangdong Province', 'city': 'Shenzhen City', 'district': 'Bao'an District', 'adcode': '440306000000', the above-mentioned administrative level four address can also be 'province': 'Guangdong Province', 'city': 'Shenzhen City', 'district': 'Bao'an District', 'town': 'None', 'adcode': '440306000000'.
[0115] As another implementation, administrative address names in the administrative address element sequence that are unrelated to the fourth-level administrative address can be retained or deleted. For example, if the administrative address element sequence includes "Beijing, Beijing, Chaoyang District, Chaoyang District, Wangjing Street, Wangjing SOHO Tower 3", then the corresponding fourth-level administrative address can include 'Province': 'Beijing', 'City': 'Beijing', 'District': 'Chaoyang District', 'Town': 'Wangjing Street', 'Wangjing SOHO Tower 3', 'adcode': '110105026000'; the corresponding fourth-level administrative address can also include 'Province': 'Beijing', 'City': 'Beijing', 'District': 'Chaoyang District', 'Town': 'Wangjing Street', 'adcode': '110105026000'.
[0116] In this embodiment of the invention, by retaining the administrative address code of the lowest administrative address element in the newly processed administrative address element sequence, and supplementing the administrative address element at the beginning of the sequence with the administrative address code, the fourth-level administrative address can be made more complete.
[0117] In practice, some users' addresses are not standardized. For example, the address may contain province / city conflicts, multiple provinces / municipalities, or abbreviations. Existing administrative address extraction schemes cannot retrieve the correct administrative address information. This invention provides an administrative address extraction method. It obtains an administrative address element sequence by matching preset address elements to the current address to be extracted. When determining whether to extract multiple or one administrative address, it splits or deletes administrative address elements from the sequence based on the administrative address code to obtain a new sequence. According to preset address element extraction logic, it determines the corresponding administrative address level four address. This allows for the extraction of correct administrative address information, improving the timeliness and accuracy of logistics delivery. Due to specific business needs, it may be desirable to extract both single and multiple addresses for addresses containing multiple provinces / municipalities. This invention enables both single and multiple address extraction, improving the efficiency of administrative address extraction.
