Description

Technical Field

[0001] This invention relates to the field of tourism-related natural language processing, and more specifically, to a method, system, device, and storage medium for updating the status of Points of Interest (POIs) based on information tracking. Background Technology

[0002] Currently, OTA (Online Travel Agency) websites and review websites provide various information about Points of Interest (POIs), including their operating status and hours. However, the lack of effective channels to verify the operating hours and status of these POIs leads to:

[0003] (1) The data update frequency is low and the timeliness is lagging;

[0004] (2) Information accuracy cannot be guaranteed.

[0005] Taking the post-pandemic era as an example, many Points of Interest (POIs) may face closures or adjustments to their operating hours. However, due to limited manpower or negligence, POI operators may not update this data to the platform in a timely manner. This can result in users encountering closed or temporarily unavailable POIs when they visit them, wasting their time and reducing their trust in the platform and POIs, thus severely impacting the user experience.

[0006] Therefore, the present invention provides a method, system, device and storage medium for updating POI status based on information tracking. Summary of the Invention

[0056] Figure 1 This is a flowchart of the POI status update method based on information tracking according to the present invention. Figure 1 As shown, the POI status update method based on information tracking of the present invention includes:

[0057] S110. Establish a set of corresponding tracking channels based on each point of interest on the platform.

[0058] S120. Perform semantic recognition on the information of the tracking channel set, and establish an update status information group based on the field corresponding to the preset business status keyword and the publication timestamp of the webpage that collects the field.

[0059] S130, Based on sorting, the update status information group with the latest publication time is selected as the current status information group. And...

[0060] S140. Correct the business status information of the point of interest based on the current status information group.

[0061] POI stands for "Point of Interest." In Geographic Information Systems (GIS), a POI can be a building, a shop, a mailbox, a bus stop, etc. Traditional GIS data collection methods require cartographers to use sophisticated surveying instruments to obtain the latitude and longitude of a point of interest before marking it. Because POI collection is a very time-consuming and labor-intensive task, the number of POIs in a GIS, to a certain extent, represents the value of the entire system. Each POI contains four aspects of information: name, category, coordinates, and classification. Comprehensive POI information is essential for enriching navigation maps. Timely POI information can remind users of road branching points and detailed information about surrounding buildings, and also facilitate finding the places you need during navigation, allowing you to choose the most convenient and smooth route for route planning. Therefore, the number of POIs on a navigation map directly affects the usability of the navigation system.

[0062] This invention retrieves social media accounts such as WeChat official accounts and Weibo accounts associated with Points of Interest (POIs) on a weekly basis and establishes a mapping relationship. It monitors social media (WeChat official accounts, Weibo) posts related to each POI in real time (daily) and identifies information involving dynamic field changes, thereby updating the dynamic fields accordingly.

[0063] In a preferred embodiment, step S110 includes:

[0064] S111. Collect the official webpages preset within the platform for each point of interest in the platform to establish a collection of official webpages.

[0065] S112. Using the name and corresponding address information of each point of interest, traverse external websites and collect web pages whose exposure parameters for each point of interest exceed a preset threshold as popular web pages to establish a set of popular web pages.

[0066] S113. Establish a set of tracking channels for corresponding points of interest based on official webpage sets and popular webpage sets, but not limited to this.

[0067] In a preferred embodiment, the exposure parameter is the number of times and / or frequency of occurrence of the point of interest on the webpages of an external website, but is not limited thereto.

[0068] In a preferred embodiment, step S120 includes:

[0069] S121. Periodically collect and track information from the channel set and perform semantic recognition to obtain target paragraphs associated with points of interest.

[0070] S122. Using preset business status keywords, a trained neural network is used to annotate the target paragraph to obtain the corresponding preset business status keyword hit fields.

[0071] S123. Create an update status information group based on a hit field and a corresponding preset business status keyword, but not limited to this.

[0072] In a preferred embodiment, step S130 includes:

[0073] S131. Sort the updates based on the publication timestamps in the update information group.

[0074] S132. The update status information group with the latest publication time shall be used as the current status information group to ensure that the latest information is used for updates and to avoid interference from historical information, but this is not a limitation.

[0075] In a preferred embodiment, step S140 includes:

[0076] S141. Based on the preset business status keywords in the current status information group, traverse the platform's published information about points of interest.

[0077] S142. If no match is found, add the preset business status keywords and the matched fields from the current status information group to the published information.

[0078] S143. When a hit occurs, the corresponding field in the published information is updated based on the hit field in the current status information group, but this is not the only limitation.

[0079] In a preferred embodiment, the business status information includes at least business status and business hours, but is not limited thereto.

[0080] The text parsing monitoring of POI dynamic fields in this invention is a systematic real-time data processing system built upon the core objective of ensuring the accuracy of POI dynamic fields. This invention periodically and purposefully monitors social media tweets, automatically determining which content involves information related to dynamic field changes through text parsing algorithms and updating the data accordingly. The advantages of this method are: 1) Information posted by official social media accounts is the most accurate; 2) Information posted by official tweets is the most timely. Thus, this invention solves the problems of inaccurate and untimely updates to dynamic fields.

[0081] This invention ensures that all dynamic fields of POIs are updated online through the system, and all data changes are traceable. It monitors data changes in real time, ensuring timely updates to POI operating hours and status information. It monitors information posted on official social media accounts and extracts information using text parsing algorithms, greatly reducing the effort required for review and improving accuracy.

[0082] Example 1: Dafang County Library is temporarily closed for renovation. Map providers such as Dianping, Baidu Maps, and Gaode Maps have not promptly disclosed this information. Using the OTA platform of this invention, the platform collects the official webpages of the point of interest "Dafang County Library" within the platform to establish an official webpage set A (which may include official webpages A1, A2, etc.). Furthermore, the name and corresponding address information of the point of interest "Dafang County Library" are used to traverse external websites, collecting webpages with exposure parameters exceeding a preset threshold as popular webpages (e.g., forums or other platforms). The exposure parameter is the number of times and frequency of the point of interest appearing on external websites, establishing a popular webpage set B (which may include popular webpages B1 and B2). The exposure parameters are obtained using existing weighted statistical algorithms, which will not be elaborated here. Based on the official webpage set and the popular webpage set, a set of tracking channels for the corresponding point of interest is established.

[0083] The OTA platform periodically collects and tracks information from a collection of channels and performs semantic recognition to obtain target paragraphs associated with points of interest. It then uses pre-defined business status keywords (e.g., business status, business hours, start of business hours, end of business hours, closing day, etc.) to annotate the target paragraphs using a trained neural network to obtain the corresponding pre-defined business status keyword's hit field. Based on a hit field and a corresponding pre-defined business status keyword, an update status information group is established. For example, if a search on a local online forum that frequently mentions the Dafang County Library reveals "The opening hours of the Dafang County Library have changed; it now opens at 10:00 AM," the pre-defined business status keyword "start of business hours" is obtained from this statement, and the hit field is "10:00 AM," but this is not a limitation.

[0084] The update status information group is sorted based on its publication timestamp, and the group with the latest publication time is designated as the current status information group. The platform's published information about points of interest is then iterated through based on preset business status keywords in the current status information group. If no match is found, the preset business status keywords and the matched fields from the current status information group are added to the published information. If a match is found, the corresponding field in the published information is updated according to the matched field in the current status information group (e.g., updating the field corresponding to "Start of Business Hours" for Dafang County Library to 10:00).

[0085] Therefore, based on the above process, the text parsing monitoring system of this invention can capture the relevant posts published by the official account in the first instance, locate the relevant information through the parsing algorithm, and finally adjust the business status of the scenic spot POI in a timely manner based on the information.

[0086] Similarly, in Example 2: When the Jiaozuo Science and Technology Museum adjusted its visiting hours, map providers such as Dianping, Baidu Maps, and Gaode Maps did not update the opening hours in a timely manner. However, the text parsing monitoring system captured the relevant posts published on the official WeChat account in the first instance and located the relevant information through the parsing algorithm. Ultimately, the opening hours of the scenic spot's POI were adjusted in a timely manner based on this information. The process will not be described in detail here.

[0087] After using this invention, the accuracy of POI dynamic fields has improved. For example, the 2022H1 sampling results show that the accuracy rate of Jingwan POI's business hours is 84.56%, which is 8.95 percentage points higher than that of Dianping; the accuracy rate of business status is 95.89%, which is 4.65 percentage points higher than that of Dianping. Furthermore, the accuracy of the parsing algorithm has improved. For example, the accuracy rate of the text parsing algorithm (the percentage of relevant information parsed) has increased from 13.73% to 84.39%, reaching a considerable level.

[0092] Information correction module 54 corrects the business status information of the point of interest based on the current status information group.

The POI status update method based on information tracking as described in claim 1, characterized in that, The step of correcting the business status information of the point of interest based on the current status information group includes: Based on the preset business status keywords in the current status information group, the platform's published information about the points of interest is traversed. If no match is found, the preset business status keywords from the current status information group and the matched field are added to the published information; and If a hit is achieved, the corresponding field in the published information is updated based on the hit field in the current status information group.

5. The POI status update method based on information tracking as described in claim 1, characterized in that, The business status information includes at least the business status and business hours.

6. A POI status update system based on information tracking, used to implement the POI status update method based on information tracking as described in claim 1, characterized in that, include: The channel collection module establishes a corresponding tracking channel collection based on each point of interest on the platform, including: collecting the official web pages preset within the platform for each point of interest to establish an official web page collection; traversing external websites with the name and corresponding address information of each point of interest, collecting web pages whose exposure parameters of the point of interest are greater than a preset threshold as popular web pages to establish a popular web page collection; and establishing a tracking channel collection corresponding to the point of interest based on the official web page collection and the popular web page collection. The update status module performs semantic recognition on the information of the tracking channel set and establishes an update status information group based on the field corresponding to the preset business status keyword and the publication timestamp of the webpage that collects the field. This includes: periodically collecting information from the tracking channel set and performing semantic recognition to obtain target paragraphs associated with the points of interest; using preset business status keywords to annotate the target paragraphs based on a trained neural network to obtain the hit field corresponding to the preset business status keyword; and establishing an update status information group based on a hit field and a corresponding preset business status keyword. The current status module, based on sorting, uses the update status information group with the latest publication time as the current status information group; and The information correction module corrects the business status information of the point of interest based on the current status information group.
