In the following description, like reference numerals refer to like elements, unless the context clearly dictates otherwise. The following description of exemplary embodiments is not intended to represent all embodiments in accordance with the present application. Rather, they are merely examples in accordance with some aspects of the present application as detailed in the appended claims.
[0025] It should be noted that the text comparison method, device, electronic equipment, medium and product provided by the present application can be used in the field of artificial intelligence, and can also be used in any field other than artificial intelligence. The application field of the text comparison method, device, electronic equipment, medium and product of the present application is not limited.
[0026] Text data comparison is a common requirement in data processing and verification, especially in system migration, data synchronization, version control and other scenarios.
[0027] For example, in the process of database localization transformation, when migrating the original database to a domestic database, it is necessary to verify whether the text data (such as reports and export files) generated by the application program after migration is consistent with that before migration.
[0028] In the financial industry, in bank or securities systems, the consistency of transaction reconciliation files generated by multiple channels (such as fixed-length UnionPay files) needs to be checked daily.
[0029] In the software testing and version release scenario, it is necessary to test whether the output files (such as CSV logs) generated by the new version of software are compatible with the old version.
[0030] In the cross-system scenario, when heterogeneous systems interact with data through files, it is necessary to ensure the consistency of data between the two parties.
[0031] The existing text comparison tools often directly compare line by line when comparing the contents of two texts. When the contents of the two texts are consistent but the recording order of the contents is different, the text comparison result will show that there are a large number of differences, and the comparison result is not accurate.
[0032] Therefore, how to accurately compare texts is a problem that needs to be solved in the industry.
[0033] The text comparison method, device, electronic equipment, medium and product provided in the application aim to solve the above technical problems of the prior art. In the text comparison process, as long as the corresponding records exist in both texts, even if the order and position of the records are different, the comparison is considered consistent. Compared with the direct comparison method without logic in the prior art, the text can be accurately compared.
[0034] The technical solutions of the application and how the technical solutions of the application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the application will be described below with reference to the drawings.
[0035] Figure 1 The flowchart of the text comparison method provided in the embodiments of the application is shown in FIG. 1. Figure 1 As shown in the figure, the method comprises the following steps.
[0036] S101, obtaining a first text and a second text, and determining, according to a preset comparison rule, an index item and at least one comparison item corresponding to each row in the first text and the second text; the index item is used to uniquely identify the row where the index item is located.
[0037] Optionally, the two text files to be compared can be taken as a file group, and a corresponding comparison rule is set for each file group. The comparison rules of different file groups can be different, so that the comparison of the text content can be flexibly performed.
[0038] Optionally, the index items of the first text and the second text can be primary keys of the first text and the second text, and the comparison items of the first text and the second text can be field values of each primary key.
[0039] Optionally, the index items of the first text and the second text can be unique keys of the first text and the second text, and the comparison items of the first text and the second text can be field values of each unique key.
[0040] S102, comparing the differences of the index items of the first text and the second text, and comparing the differences of the comparison items of the first text and the second text under the same index item, to obtain a comparison result.
[0041] Optionally, the comparison result file can be generated in file granularity, and the line comparison result is written in the comparison result file according to the index item, so as to quickly locate the text problem of the user and improve the processing efficiency.
[0042] For example, the A file and the a file are defined as a comparison group, and after comparison of the comparison group, a comparison result file is generated to store the differences between the A file and the a file.
[0043] If the index item 1 exists in the file A and does not exist in the file a, the file A. index item 1 does not exist in the file a is recorded in the comparison result file. If the index item 2 exists in the file A and the file a, and the comparison item value corresponding to the index item 2 in the file A is inconsistent with the comparison item value corresponding to the index item 2 in the file a, the file A. index item 1. comparison item is not equal to the file a. index item 1. comparison item is recorded in the comparison result file.
[0044] Optionally, the above steps can be repeatedly performed for multiple comparison groups to achieve batch efficient comparison of multiple groups of texts.
[0045] In the embodiments of the present application, according to the preset comparison rule, the index item and the at least one comparison item corresponding to each row in the first text and the second text are determined, the rows of the text are uniquely identified through the index item, and the mapping relationship between the records of the first text and the second text is established through the comparison item, which upgrades the comparison of physical rows to the comparison of logical records; by comparing the index item difference and the comparison item difference under the same index item of the first text and the second text, the comparison of the texts can be efficiently and accurately performed when the record orders of the two text files are different.
[0046] On the basis of the above embodiments, the comparison rule can be flexibly configured according to actual needs. In some embodiments, the comparison rule includes: the index item and the at least one comparison item are obtained according to a preset length; or, the index item and the at least one comparison item are obtained according to a separator.
[0047] In a specific implementation, each file group to be compared is configured with a corresponding comparison rule in advance. Each comparison rule includes the file name of the first file, the file name of the second file, and the acquisition rule of the index item and the comparison item. The first file is used to store the first text, and the second file is used to store the second text.
[0048] In a possible implementation, the acquisition rule of the index item and the comparison item can be that the index item and the at least one comparison item are obtained according to a preset length.
[0049] Optionally, the lengths of the index item and the comparison item can be different, and the lengths of different comparison items can also be different. The length of each index item and each comparison item can be flexibly set according to the actual text type or comparison needs.
[0050] Optionally, when the acquisition rule of the index item and the comparison item is that the index item and the at least one comparison item are obtained according to a preset length; the comparison rule further includes: the start point and the end point of the index item and the at least one comparison item, or the length of the index item and the at least one comparison item.
[0051] According to the start point and the end point of the index item and the at least one comparison item or the length of the index item and the at least one comparison item, each line of the first text and the second text can be divided into the index item and the at least one comparison item.
[0052] It can be understood that the division of the index item and the comparison item in each line of the first text and the second text is the same, so that the index item and the comparison item in different lines of the first text and the second text can be compared.
[0053] For example, the comparison rule can include:
[0054] File group number: 1;
[0055] First file name: A.bin;
[0056] Second file name: a.bin;
[0057] Acquisition rule of the index item and the comparison item: fixed length;
[0058] Start point and end point of the index item: 1, 10;
[0059] Start point and end point of the comparison item 1: 11, 15;
[0060] Start point and end point of the comparison item 2: 16, 17;
[0061] Start point and end point of the comparison item 3: 18, 26;
[0062] Start point and end point of the comparison item 4: 27, 30.
[0063] For example, the comparison rule can further include:
[0064] File group number: 1;
[0065] First file name: A.bin;
[0066] Second file name: a.bin;
[0067] Acquisition rule of the index item and the comparison item: fixed length;
[0068] Length of the index item: 10;
[0069] Length of the comparison item 1: 5;
[0070] Length of the comparison item 2: 2;
[0071] Length of the comparison item 3: 9;
[0072] Length of the comparison item 4: 4.
[0073] In a possible implementation, the obtaining rule of the index item and the contrast item can be that the index item and the at least one contrast item are obtained according to the delimiters.
[0074] The delimiters can include, but are not limited to, line breaks, paragraph marks (such as commas, periods), or other logical delimiters for organizing text in a document.
[0075] In the embodiments of the present application, the index item and the contrast item obtained in the fixed-length or delimiter manner are supported, and the contrast rule is flexible and can be adapted to various text types.
[0076] In some embodiments, the difference between the index items of the first text and the second text is contrasted, including:
[0077] The first index item and the second index item are determined by contrasting the respective index items of the first text and the second text; wherein the first text contains the first index item and does not contain the second index item, and the second text contains the second index item and does not contain the first index item.
[0078] In a specific implementation, by contrasting the index items in the first text with the index items in the second text, the index items not contained by each other in the first text and the second text can be determined, that is, the first index item contained by the first text but not contained by the second text, and the second index item contained by the second text but not contained by the first text, so as to determine the row record missing in the first text and the second text.
[0079] In a possible implementation, the difference between the contrast items of the first text and the second text under the same index item is contrasted, including:
[0080] The third index item is determined, which is an index item contained by both the first text and the second text.
[0081] For the third index item, a first contrast item corresponding to the third index item in the first text is obtained, and a second contrast item corresponding to the third index item in the second text is obtained.
[0082] The difference between the first contrast item and the second contrast item is determined.
[0083] In a specific implementation, after the third index item contained by both the first text and the second text is determined, each first contrast item value corresponding to the third index item in the first text can be contrasted with each first contrast item value corresponding to the third index item in the second text, so that the field value difference of the row record in the first text and the second text can be determined.
[0084] In the embodiments of the present application, by contrasting the index item missing and the contrast item difference of the first text and the second text, the row record level difference and the field level difference of the first text and the second text can be determined, and the contrast of the text can be accurately and clearly implemented.
[0085] In some embodiments, the first text and the second text are obtained, including:
[0086] loading the first text and the second text into memory;
[0087] determining, according to a preset comparison rule, an index item and at least one comparison item corresponding to each line in the first text and the second text, including:
[0088] parsing, according to the comparison rule, the memory object of the first text and the memory object of the second text to determine the index item and the at least one comparison item corresponding to each line in the first text and the second text;
[0089] storing the parsed first text and the parsed second text as a memory object in memory respectively, and storing the index item and the at least one comparison item corresponding to each line as a sub-object of the memory object.
[0090] In a specific implementation, the first file and the second file to be compared are stored in different file directories, the first file stores the first text, and the second file stores the second text. The first file, the second file, and the corresponding comparison rule are loaded into memory respectively, and the first file and the second file are parsed according to the comparison rule, and each line of the first file and the second file is divided to obtain the index item and the at least one comparison item. The parsed first file and the parsed second file are stored as a memory object in memory, wherein each memory object includes a plurality of sub-objects, and each sub-object is used to store the index item and the comparison item corresponding to a line of the text.
[0091] When comparing the first file and the second file, the index item stored in each sub-object in the memory object corresponding to the first file can be compared with the index item stored in each sub-object in the memory object corresponding to the second file to determine the difference between the index items of the first file and the second file. For the index item involved in both the first file and the second file, the comparison item value in the sub-object of the first file corresponding to the index item and the comparison item value in the sub-object of the second file corresponding to the index item are obtained and compared to determine the difference between the comparison items of the first text and the second text under the same index item, so that the comparison of the texts is efficiently and orderly performed.
