Description

Technical Field

[0001] This invention relates to the field of logistics technology, and in particular to a method and related equipment for identifying the status of parcel transportation. Background Technology

[0002] With the rapid development of cross-border e-commerce, the online shopping demand of global users has surged. This increased downstream demand has spurred upstream development, resulting in a proliferation of e-commerce platforms and shipping channels, each with its own unique characteristics. The most obvious manifestation of this is the exponential increase in the number of parcels shipped in recent years. Along with this surge, monitoring the transportation status of these parcels has become a major concern. Currently, logistics providers offer only three basic tracking statuses: pending shipment, delivered, and arrived. E-commerce platforms struggle to monitor the detailed status of parcels in a timely manner, and buyers, lacking concrete understanding of these status descriptions, become confused about the tracking status, leading to unnecessary communication costs between buyers and sellers. Furthermore, the difficulty of monitoring the specific status of parcels makes it difficult for e-commerce platforms to intervene promptly when issues arise, resulting in a poor shopping experience for buyers. Summary of the Invention

[0003] The technical problem this invention aims to solve is that the logistics trajectory status of most parcels is relatively simple. To address the shortcomings of existing technologies, this invention provides a parcel transportation status identification method and related equipment.

[0007] Based on the package information, obtain the logistics trajectory information corresponding to the package information, wherein the logistics trajectory information includes a number of logistics nodes and node information corresponding to each logistics node;

[0008] For each logistics node, the node status corresponding to that logistics node is determined based on the node information corresponding to that logistics node.

[0011] The package transportation status identification method further includes, after obtaining the logistics trajectory information corresponding to the package information, the following steps:

[0012] When the logistics tracking information is empty, the transportation status corresponding to the package information is "cannot be found".

[0013] The package transportation status identification method, wherein determining the node status corresponding to the logistics node based on the node information corresponding to the logistics node includes:

[0017] The package transportation status identification method, wherein determining the node status corresponding to the logistics node based on the status word includes:

[0018] When the status word is a receipt word, determine whether the status words corresponding to the first N logistics nodes of the logistics node are receipt words, where the receipt word is a word related to receipt, and N is a positive integer;

[0019] If so, then the node status corresponding to that logistics node is determined to be successfully signed for.

[0020] The package transportation status identification method, wherein determining the node status corresponding to the logistics node based on the status word includes:

[0021] When the type of the status word is a transportation word, determine whether there is a logistics node with a status change between the node time corresponding to the logistics node and the current time.

[0022] When there are no logistics nodes that are in a state change between the node time corresponding to the logistics node and the current time, calculate the time difference between the node time and the current time;

[0023] When the time difference is greater than a preset time threshold, the node status corresponding to the logistics node is determined to be "transportation too long".

[0024] The package transportation status identification method, wherein determining the transportation status corresponding to the package information based on the node status corresponding to all the logistics nodes includes:

[0025] When the number of logistics trajectory information is greater than one, all the logistics trajectory information is merged to obtain logistics merge information;

[0026] The logistics node closest to the corresponding node in the logistics consolidation information is taken as the target node, and the node status corresponding to the target node is taken as the transportation status corresponding to the package information.

First, the parcel information to be identified is obtained, and then logistics trajectory information is derived based on this information. Next, the status of each logistics node in the logistics trajectory information is confirmed. Since the status of each logistics node is confirmed, rather than relying on lengthy descriptions typical of logistics, users can quickly obtain the status of their parcel at each logistics node. Furthermore, the transportation status of the parcel is determined based on the status of all logistics nodes, allowing users to quickly and easily assess and process parcels in different statuses.

It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0043] like Figure 1 As shown, this embodiment provides a method for identifying the status of package transportation. For ease of explanation, a common server is used as the execution subject in the description. The server here can be replaced by a tablet, computer, or other device with data processing capabilities. The method for identifying the status of package transportation includes the following steps:

[0044] S10. Obtain package information.

[0045] Specifically, after a user sends a package, the logistics provider provides package information linked to that package. The user then enters this package information into the server. When the server initiates package delivery status recognition, it retrieves the package information from the stored data.

[0046] In this embodiment, the package information includes the package tracking number and may also include the name of the logistics provider responsible for the package. Since different logistics providers currently use different tracking numbers, a different tracking number identification algorithm is pre-set in the server, allowing the server to easily identify the logistics provider's name based on the tracking number. However, globally, there are many logistics providers, and naming rules change rapidly. Including the logistics provider's name in the package information will make subsequent retrieval of logistics tracking information more accurate and faster.

[0047] S20. Based on the package information, obtain the logistics trajectory information corresponding to the package information.

[0048] Specifically, since the logistics status of logistics providers is publicly available and searchable, after the server obtains the package information, it can retrieve the logistics trajectory information corresponding to the package information through the logistics trajectory query interface corresponding to the service provider's name.

[0049] The logistics trajectory information includes several logistics nodes and node information corresponding to each logistics node. The logistics trajectory information includes multiple logistics nodes, each logistics node representing a point where the package's transportation status changes. For example, "On date B, year A, the express delivery arrived at location D," this is a logistics node, and its corresponding node information is "the express delivery arrived at location D."

[0050] Because some logistics providers do not necessarily enter the logistics data into their systems when issuing package tracking numbers, the logistics tracking information obtained through the query interface may show "No relevant information found." If the obtained logistics tracking information does not include logistics nodes, this logistics node information is considered empty, and the transportation status corresponding to the package information is directly confirmed as unsearchable.

[0051] S30. For each logistics node, determine the node status corresponding to that logistics node based on the node information corresponding to that logistics node.

[0052] Specifically, for each logistics node, since it carries node information, and this node information includes the node's status, its corresponding status, i.e., the node status, can be determined based on the node information. Because different logistics providers use vastly different descriptive languages, the same status can be expressed in different ways, such as "express delivery arrived at location D," "express delivery delivered to the branch at location D," or "express delivery is at location D." Although the expressions differ, the meaning is the same. Therefore, a unified status language is pre-defined to describe node status; this unified status language is the node status type. In this embodiment, node status types include: not found, pending online tracking, in transit, arrived for pickup, successfully signed for, delivery failed, anomaly present, and transit time too long. Subsequently, node information is matched with node status types.

[0053] In one method of determining node states based on node information, a semantic recognition model can be pre-trained. This model can categorize training sentences with different content into pre-defined node state types. Therefore, once node information is obtained, it can be input into the trained semantic recognition model, and the model can then perform semantic recognition on the node information to determine its corresponding node state type.

[0054] Since most languages ​​describing package status are quite similar and use relatively few words, another method for determining node status in this embodiment is to use the keyword method. The specific process is as follows:

[0055] A10. Extract keywords from the node information corresponding to the logistics node to obtain the main status keywords.

[0056] Specifically, since node information is generally a single sentence, the logistics node information is first segmented into several words. For example, "express delivery arrived at location D" in the previous text can be segmented into "express delivery", "arrived", and "location D". These words are then used as the main status keywords.

[0057] A20. Based on a preset state term library, match the main state keywords to obtain the state terms corresponding to the main state keywords.

[0058] Specifically, a lexicon containing multiple state words is pre-set, i.e., a state lexicon.

[0059] Different state words are categorized into different types because they describe different states. Therefore, different state words are pre-classified into different types.

[0060] The obtained main status keyword is matched with status words in the status word library. The match does not need to be identical; a similarity score can be used. For example, if the main status word is "arrived," the matching keyword is "delivered." The similarity score between the two words is calculated. When the similarity score reaches a preset threshold, "delivered" is determined to correspond to the main status keyword "arrived."

[0061] A30. Determine the node status corresponding to the logistics node based on the type of the status word.

[0062] Specifically, multiple status words can correspond to a status type. For example, the status type of "in transit" can be represented by status words such as "arrived", "delivered", "next station", and "sent out".

[0063] Therefore, once the status word corresponding to the main status keyword is determined, the node status corresponding to the logistics node can be determined based on the type of status word.

[0064] In this embodiment, the node status of "awaiting online", "in transit", "arrived for pickup", and "delivery failed" can be directly determined by keyword matching. However, keyword matching may not be accurate for "transit time too long" and "successfully signed for".

[0065] Regarding "successfully signed for," in the actual delivery process, once a package is signed for, the logistics tracking information provided by the logistics provider stops updating. In a complete package tracking information list, the most recent entries will show keywords related to package signing such as "signed for," "picked up," "delivered successfully," and "placed in a parcel locker." Therefore, to ensure that the currently identified logistics node truly indicates that the package has been signed for, the determination of whether a logistics node is "successfully signed for" is based on the node status of the previous few logistics nodes. The process is as follows:

[0066] A311. When the status word is a receipt word, determine whether the status words corresponding to the first N logistics nodes of the logistics node are receipt words.

[0067] Specifically, the number of logistics nodes preceding the current logistics node to be judged is preset. Here, "previous" is arranged according to the chronological order of other logistics nodes relative to this current logistics node. For example, the nodes in the logistics trajectory information are arranged in chronological order as node E, node F, node G, and node H. If the current determined logistics node is node H, and the preset N is 2, then the preceding N logistics nodes are nodes F and G.

[0068] When the status word is of type "receipt word", determine whether the status words corresponding to the first N logistics nodes are "receipt words".

[0069] A312. If so, then determine that the node status corresponding to the logistics node is successful receipt.

[0070] Specifically, if so, it means that the logistics status is close to being signed for before the current logistics node, therefore, the node status corresponding to the logistics node is determined to be "successfully signed for".

[0071] A313. If not, then the node status of the logistics node shall be further determined.

[0072] Specifically, if not, it means that the logistics status of the logistics node was not close to the sign-for status before that logistics node, but rather the logistics node itself was close to the sign-for status. Therefore, it is necessary to further determine the status of the logistics node.

[0073] In this embodiment, further determination of logistics nodes may include any one of the following methods for determining the node status as "awaiting online", "in transit", "arrived for pickup", "successfully signed for", "delivery failed", "abnormality exists", and "transit time too long". In addition to the methods for further determining the node status provided in this embodiment, other publicly available or used methods for determining the node status may also be used, such as determining based on keywords or semantics.

[0074] Because keyword matching cannot truly understand the meaning of node information compared to semantic recognition, it has a high false positive rate for the "successfully signed" status. Comparing the current logistics node's status with previous nodes can further improve the accuracy of determining whether the current node's status is "successfully signed."

[0075] Regarding the "transit time too long" scenario, it is not directly displayed in the logistics track node. Therefore, the method used to determine whether a node status is "transit time too long" is as follows:

[0076] A321. When the type of the state word is a transportation word, determine whether there is a logistics node with a state change between the node time corresponding to the logistics node and the current time.

[0077] The transport term refers to a status term related to the node status type during transport, such as "heading to", "next stop is", or "sent out".

[0078] When the status word of a logistics node is "transportation," it means that at the corresponding node time, the package has been transported. If there is a status change during the package transportation process, for example, if the current logistics node is node A with the status word "in transit," and the next node, node B, has the status word "arrived for pickup," then the logistics node with a status word different from the current logistics node's status word is called a status change node.

[0079] If the status of a package does not change for a long time, there may be an anomaly. In this case, the user and the logistics provider need to communicate in a timely manner. Therefore, packages that may have excessively long transit times need to be marked separately.

[0080] The judgment method used in this embodiment is to determine whether there is a state change node between the node time corresponding to the logistics node, such as 12:00 on March 12, 2022, and the current time, such as 12:00 on March 14, 2022.

[0081] A322. When there are no logistics nodes that are state-changing nodes between the node time corresponding to the logistics node and the current time, calculate the time difference between the node time and the current time.

[0082] Specifically, if the condition is met, it means the package is in normal delivery status and has moved from transit to the next stage. If the condition is not met, it means the package is still in transit.

[0083] If the transportation time is short, it may be in a normal transportation state; if the transportation time is too long, it may be in an abnormal state of excessively long transportation.

[0084] Calculate the time difference between the logistics node and the current time to evaluate whether the transportation time corresponding to the logistics node is reasonable.

[0085] A323. When the time difference is greater than a preset time threshold, the node status corresponding to the logistics node is determined to be "transportation too long".

[0086] In this embodiment, different time thresholds are pre-set for different logistics scenarios. These time thresholds can be statistically analyzed based on the user's past waybill data, for example, calculating the average time for transportation from location A to location B. When the origin of the current package information is location A and the destination is location B, the time threshold corresponding to this logistics trajectory information is set to the previously calculated average time.

[0087] When the time difference is greater than a preset time threshold, the node status corresponding to that logistics node is determined to be "transportation too long". Similarly, when the time difference is less than the preset time threshold, the node status corresponding to that logistics node is determined to be "in transit".

[0088] S40. Determine the transportation status corresponding to the package information based on the node status of all the logistics nodes.

[0089] Specifically, when the node status of all logistics nodes is obtained, the node status of the logistics node closest to the corresponding node at that time is taken as the transportation status of the package information.

[0090] For example, some packages may be redelivered after their status has changed from "arrived and awaiting pickup" to "arrived and awaiting pickup," for instance, if the recipient requests a change of address. This will generate a new logistics tracking path, and if the delivery ultimately fails, the package status will be "delivery failed" at the latest logistics node. Alternatively, some packages may fail to be delivered and then be redelivered, eventually reaching the "arrived and awaiting pickup" node. In this case, the package status will be determined as "arrived and awaiting pickup."

[0091] Furthermore, some logistics providers have more than one tracking record. For example, Dutch Post typically has five tracking records. Therefore, when the number of tracking records is greater than one, all tracking records are merged to obtain merged tracking information. Then, the logistics node with the smallest time difference between its corresponding time and the current time in the merged tracking information is selected as the target node. Finally, the node status corresponding to the target node is used as the corresponding transportation status of the package.

[0092] Based on the above-described parcel transportation status identification method, the present invention also provides a parcel transportation status identification device 100. The device includes:

[0093] The first acquisition module 110 is used to acquire package information, wherein the package information includes the package tracking number;

[0098] The parcel transportation status device further includes a query result module, which is used for:

[0099] When the logistics tracking information is empty, the transportation status corresponding to the package information is "cannot be found".

[0102] The matching unit is used to match the main state keyword based on a preset state word library to obtain the state word corresponding to the main state keyword;

[0103] The determining unit is used to determine the node status corresponding to the logistics node based on the type of the status word.

[0104] Specifically, the determining unit is used for:

[0105] When the status word is a receipt word, determine whether the status words corresponding to the first N logistics nodes of the logistics node are receipt words, where the receipt word is a word related to receipt, and N is a positive integer;

[0106] If so, then the node status corresponding to that logistics node is determined to be successfully signed for.

[0107] The determining unit is further configured to:

[0108] When the type of the status word is a transportation word, determine whether there is a logistics node with a status change between the node time corresponding to the logistics node and the current time.

[0109] When there are no logistics nodes that are in a state change between the node time corresponding to the logistics node and the current time, calculate the time difference between the node time and the current time;

[0110] When the time difference is greater than a preset time threshold, the node status corresponding to the logistics node is determined to be "transportation too long".
