In the import-export ratio algorithm, α 1 is 200, α 2 is 150;

[0042] Import data JK n1 All trading countries in MG n1 The country selling the goods is recorded as the trading country MG n1 Importing country; export data CK n1 All Buy Trade Countries MG n1 The country of the commodity is recorded as trading country MG n1Exporting countries; using the import and export ratio algorithm to obtain the trading country MG n1 Import and export

[0043] F= a 1 ×g 1 ×f n1

[0044] Eigenvalue; the in-out ratio algorithm is: α 2 ×g 2 × sum , where F is the import and export characteristic value, α 1 For trading countries MG n1 The number of importing countries, α 2 For trading countries MG n1 The number of exporting countries, g 1 For trading countries MG n1 Import data of JK n1 The sum of all commodity prices recorded in g 2 For trading countries MG n1 Export data of CK n1 The sum of all commodity prices recorded in, f n1 For trading countries MG n1 The sum of all commodity prices recorded in the corresponding cross-border trade data, f sum It is the sum of all commodity prices recorded in the cross-border data corresponding to all trading countries MG;

[0045] In the specific implementation process, for example, during a data processing, the trade country MG n1 The number of importing and exporting countries is 5 and 10 respectively. 1 and 2 are 10000 and 500000 respectively, f n1 is 510000, f sum is 5100000, then the import and export characteristic value can be calculated to be 0.001;

[0046] Trade country MG n1 All importing countries, all exporting countries, and import and export characteristic values ​​are recorded as trading countries MG n1 Characteristics of cross-border trade;

[0047] Based on trade country MG n1 The method for obtaining cross-border trade characteristics is to obtain the cross-border trade characteristics corresponding to all trading countries MG.

[0048] The search feedback upload module is used to record the searched data as searched trade data when the user searches for trade data, perform text extraction on the searched trade data, and provide search feedback to the user based on the text extraction result;

[0049] The search feedback uploading module includes a search feedback generating unit, and the search feedback generating unit is configured with a search feedback generating strategy, and the search feedback generating strategy includes:

[0050] When a user searches for trade data, the data searched by the user is recorded as search trade data, and the search trade data is segmented based on text extraction, and all Chinese words obtained by segmentation are recorded as search Chinese words SZ 1 To search Chinese word SZ k , extract nouns from all search Chinese words SZ based on AI, and record the mentioned nouns as search nouns SM 1 To search term SM j , where j is a positive integer less than or equal to k and greater than or equal to 1;

[0051] In the specific implementation process, for example, in a data processing, the search trade data obtained is "China exports high-quality silk to Japan", then all the Chinese words SZ obtained through word segmentation processing are "China", "to", "Japan", "export", "of", "high-quality" and "silk", and the search nouns SM obtained by noun extraction are "China", "Japan", "export" and "silk"; by screening the Chinese words SZ to obtain the search noun SM, it can reduce the time consumed in data search, and improve the search efficiency of the search engine while refining the search target;

[0052] Use all search terms SM to retrieve the cross-border trade data of all trading countries MG, and record the trading countries MG corresponding to the cross-border trade data containing all search terms SM as candidate countries;

[0053] The commodity exporting countries and commodity importing countries in the searched trade data are recorded as the searched exporting countries and the searched importing countries respectively. When the searched exporting countries are not included in the candidate countries, the search feedback is set to no search target; when the searched exporting countries are included in the candidate countries, the searched exporting countries in the candidate countries are recorded as the central countries; when the searched importing countries are included in the importing countries of the central country, the search feedback is set to successful search; when the searched importing countries are not included in the importing countries of the central country and the searched importing countries are included in the exporting countries of the central country, the search feedback is set to import and export errors;

[0054] In the specific implementation process, for example, in a data processing, if the export country of the goods in the searched trade data is China and the import country is Japan, the central country is set to China. When China's import countries include Japan, the search feedback is set to a successful search, that is, the trade data required by the user can be searched;

[0055] When the searched import country is not included in the import countries and export countries of the central country, the search feedback is set to no search target.

[0056] The search result generation module is used to segment the cross-border trade database based on the generated search feedback, and use AI to search the search trade data in the cross-border trade database, and send the search results to the user, wherein the cross-border trade database is used to store the cross-border trade data of all countries obtained from the Internet;

[0057] The search result generation module includes a search result generation unit, and the search result generation unit is configured with a search result generation strategy, and the search result generation strategy includes:

[0058] When the search feedback is no search target, all cross-border trade data are recorded as invalid data; when the search feedback is import and export errors, the cross-border trade data between the central country and the searched import country are recorded as retained data and all other cross-border trade data are recorded as invalid data; when the search feedback is a successful search, the cross-border trade data between the central country and the searched import country are recorded as valid data and all other cross-border trade data are recorded as invalid data;

[0059] When the reserved data or valid data is obtained, AI is used to search the search trade data in the cross-border trade database, and the search results are sent to the user; when AI is used to search the search trade data, the cross-border trade data corresponding to multiple trading countries MG are obtained, and the searched cross-border trade data are sorted from large to small based on the import and export characteristic values ​​of the trading countries MG corresponding to the cross-border trade data;

[0060] In the specific implementation process, the larger the import and export characteristic value, the more market share the trading country MG corresponding to the import and export characteristic value occupies in world trade. Therefore, when searching for multiple cross-border trade data, sorting the searched cross-border trade data from large to small based on the import and export characteristic values ​​can help users select the searched data, give priority to popular trading countries or unpopular trading countries, thereby improving the user's trade data search efficiency.
