Fig. 1 is a flowchart illustrating a text comparison method according to an exemplary embodiment of the present disclosure. As shown in fig. 1, the method includes steps 101 to 104.
In step 101, an original text file and a comparison text file are obtained. The original text file and the comparison text file can be files in any format, such as a PDF file, a picture file, even a video file, and the like.
In step 102, a first character string composed of the original text and a second character string composed of the comparison text are respectively obtained according to the original text file and the comparison text file. The original text and the comparison text are character information obtained by identification in the original text file and the comparison text file, and the character information obtained by identification corresponding to the original text and the comparison text is respectively determined as a whole continuous character string, so that the first character string formed by the original text and the second character string formed by the comparison text are obtained.
Whether the original text file and the comparison text file are single-page or multi-page files, the original text and the comparison text identified from the original text file and the comparison text file are respectively taken as an integral character string.
In step 103, the first character string and the second character string are compared to determine a comparison result.
After the original text and the comparison text identified in the original text file and the comparison text file are respectively determined as the first character string and the second character string, comparison between the original text file and the comparison text file can be directly performed according to the first character string and the second character string. Therefore, the comparison information between the original text file and the comparison file can be determined and obtained through the comparison result between the character strings.
In step 104, the comparison result is displayed in the original text file and/or the comparison text file.
The method for displaying the comparison result in the original text file and/or the comparison text file can be various. For example, the comparison result may be displayed in both the original text file and the comparison text file, or may be displayed only in the original text file or only in the comparison text file; the comparison result may be displayed in a list form, or each comparison result may be displayed according to a text position associated with the comparison result, and the like. When the comparison result is displayed according to the text position associated with the comparison result, when the first character string and the second character string are determined according to the original text and the comparison text identified in the original text file and the comparison text file, the configuration of the original text and the comparison text in the first character string and the second character string can be determined according to, for example, the page number order and the text arrangement order in each page, so that the positions of the comparison result in the original text file and the comparison text file can be determined according to the positions of the comparison result in the first character string and the second character string respectively, and the comparison result is displayed in the corresponding files.
According to the technical scheme, when the original text file and the comparison text file are compared, the first character string and the second character string can be respectively formed by the original text identified in the original text file and the comparison text identified in the comparison text file, so that any file information except characters in the two character strings is not required to be considered when the original text file and the comparison text file are compared, a method for comparing different text files is greatly simplified, the text comparison efficiency is improved, comparison results obtained by comparing the first character string corresponding to the original text file and the second character string corresponding to the comparison text file can be displayed in the original text file and/or the comparison text file, and the comparison results can be displayed more intuitively.
In a possible embodiment, the comparison result is one or more tag data, and the tag data includes a tag type and a tag position; wherein the label position comprises a start-stop character position of a first text corresponding to the label data in the first character string and a start-stop character position of a second text corresponding to the label data in the second character string, and the start-stop character position of the first text and the start-stop character position of the second text are start-stop character offset values of the label position in the first character string and the second character string respectively; the tag types include one or more of the following four types: the tag type may also include other types, and the kind of the tag type is not limited in this disclosure. In addition, the tag data may further include tag IDs, which may be sequentially assigned from 0 to characterize the number of the tag data.
Specifically, the tag data in the alignment result can be shown in table 1. Four different types of tag data are shown in table 1, wherein tag _ ID characterizes the tag ID of the tag data; tag represents the tag type of the tag data, including equal (same), replace (replacement), delete (deletion) and insert (insertion); the array A in the tag position represents the first character string formed by the original text in the original text file, the array B in the tag position represents the second character string formed by the comparison text in the comparison text file, and the number of each character in the character string is represented by an array subscript, for example, A [0] represents the first character in the array A; that is, the start-stop character position of the first text corresponding to the tag data in the first character string and the start-stop character position of the second text corresponding to the tag data in the second character string may be represented in the form of an array; the start-stop character offset value may be an offset value relative to the first character in the string, i.e., may be represented by the array index.
TABLE 1
In addition, because the format of the original text file and the format of the comparison text file can be any format, before the first character string and the second character string are obtained, a certain conversion process can be performed on the original text file and the comparison text file, and then the text content in the original text file and the comparison text file can be extracted to obtain the first character string and the second character string. An exemplary method of obtaining the first string and the second string is given in fig. 2.
Fig. 2 is a flowchart illustrating a text comparison method according to yet another exemplary embodiment of the present disclosure. As shown in fig. 2, the method further includes steps 201 to 203.
In step 201, the original text file and the comparison text file are converted into one or more image format files. The specific image format of the image format file is not limited in this disclosure.
In step 202, character recognition is performed on the image format files to obtain text information corresponding to each image format file. The method of character recognition may be conventional OCR recognition, or may be any other method of character recognition.
In step 203, according to the page number sequence of the image format file in the original text file or the comparison text file, the text information corresponding to the image format file is spliced to obtain the first character string and the second character string corresponding to the original text file and the comparison text file, respectively.
Under the condition that the original text file and/or the comparison text file comprises a plurality of file pages, the text information obtained by identification also respectively corresponds to corresponding page information, and at the moment, the text information respectively corresponding to the plurality of pages can be sequentially spliced according to the sequence of the original pages, so that the first character string and the second character string respectively corresponding to the original text file and the comparison text file are obtained. If the document page number in the original text file and/or the comparison file is a single page, the first character string and/or the second character string can be determined only according to the arrangement sequence of the text information obtained by identification in the original text file or the comparison text file.
Fig. 3 is a flowchart illustrating a text comparison method according to yet another exemplary embodiment of the present disclosure. As shown in fig. 3, the method further comprises step 301 and step 302.
In step 301, a target file corresponding to the tag data is determined according to the tag type in the tag data, where the target file includes an original text file and/or a comparison text file.
In step 302, the tag data are respectively displayed in the target files corresponding to the tag data.
As shown in table 1 above, the tag types of the tag data may be equal (same), replace (replacement), delete (deletion), insert (insertion). For an original text file, the tag data belonging to the insert type is characterized by comparing text contents which are newly inserted and do not exist in the text file relative to the original text file in the text file, so that the tag position of the tag data in the original text file only corresponds to an insertion position, and no corresponding text exists, and therefore the tag data of the type can not be displayed in the original text file, and therefore, the target file corresponding to the tag data of which the tag type is the insert type can be preset and does not include the original text file. For the comparison text file, the label data belonging to the delete type represents the deleted text content which does not exist in the original text file relative to the comparison text file, so that the label position of the label data in the comparison text file only corresponds to one insertion position and does not have a corresponding text, and the label data of the type also does not need to be displayed in the comparison text file, so that the target file corresponding to the label data of which the label type is the delete type can be preset and does not include the comparison text file. The label data with the label types of equal and replace can be displayed in both the original text file and the comparison text file, so that the target file corresponding to the label data with the label types of equal and replace can comprise both the original text file and the comparison text file.
Fig. 4a is a schematic diagram illustrating a comparison result displayed in an original text file in a text comparison method according to yet another exemplary embodiment of the present disclosure, and fig. 4b is a schematic diagram illustrating a comparison result displayed in a comparison text file in a text comparison method according to yet another exemplary embodiment of the present disclosure. As shown in fig. 4a, the original text file shows tag data of equal (same) type 1, replace (replacement) type 2, delete (deletion) type 3, as shown in fig. 4b, and the comparison text file shows tag data of equal (same) type 1, replace (replacement) type 2, insert (insertion) type 4; the label data of equal (same) type 1 is displayed in the text in a straight-down line form, the label data of place (replacement) type 2 is displayed in the text in a wavy-down line form, the label data of delete (type 3) is displayed in the text in a deleted symbol form, and the label data of insert (type 4) is displayed in the text in a double-down straight-down line form.
Therefore, before the comparison result is displayed in the original text file and the comparison text file, the corresponding relation between each label type and the original text file and the corresponding relation between each label type and the comparison text file can be preset according to the self meaning of each label type, so that the label data are distributed, and the display picture can be clearer and simpler when the comparison result is finally displayed.
Fig. 5 is a flowchart illustrating a text comparison method according to yet another exemplary embodiment of the present disclosure. As shown in fig. 5, the method further includes step 501 and step 502.
When the comparison result is mapped back to the original text file and the comparison text file for display, the mapping may be performed according to the correspondence between each character in the first character string and the second character string and the text position in the original text file and the comparison text file, and therefore, the text comparison method may further include step 501 as shown in fig. 5.
In step 501, page information of the original text file and the comparison text file is obtained, where the page information includes a file page number, a total number of characters included in each page of file, a number of text lines included in each page of file, and a number of characters included in each text line. The step 501 may be executed according to an execution sequence of the steps shown in fig. 5, or may be executed before or after the first character string and the second character string are obtained, where the execution sequence of the steps is not limited as long as it is ensured that the tag data can be displayed according to the page information of the original text file and the comparison text file when the tag data is displayed.
Further, when the tag data is displayed in the target files corresponding to the tag data, the display may be performed according to step 502 and step 503 shown in fig. 5.
In step 502, a mapping relationship between the tag data and the corresponding target file is determined according to the page information and the tag position.
In step 503, the label data are mapped to the corresponding target files for display according to the mapping relationship.
In the process of determining the mapping relationship, according to the label position corresponding to each label data, text position information corresponding to the label data can be directly searched in the original text file and/or the comparison text file, so that each label data is mapped to the corresponding text content.
For example, after comparing the original text file and the comparison text file as shown in fig. 4a and 4b, the obtained comparison result may include the tag data as shown in table 2 below.
TABLE 2
The tag positions included in the tag data with the tag ID of 0 in table 2 are a [0] -a [72] "- >" B [0] -B [72], and since the tag type is equal (same) type, the tag data can be simultaneously displayed in the original text file and the comparison text file, and the mapping relationship between the tag data with the tag ID of 0 and the original text file and the comparison text file can be determined by searching the text character position corresponding to the 1 st character and the text character position corresponding to the 73 th character in the original text file and the comparison text file from the head, that is, the first character to the sixth character in the fourth row in the first row of the two text files. Alternatively, the tag data may be displayed according to a display method as described below.
In a possible implementation manner, under the condition that the page information of the original text file and the comparison text file is known, where the page information includes a file page number, a total number of characters included in each page file, a number of text lines included in each page file, and a number of characters included in each text line, the method for displaying the tag data on the corresponding text of the original text file and/or the comparison text file respectively through the page information and the tag position may first allocate the text page, the text line in each page, and each character in each line step by step, and then search for a specific position of the corresponding character. For example, the file page number corresponding to the tag data may be determined according to the file page number and the total number of characters included in each file, so that the tag data corresponding to each file can be obtained first; then determining a text line corresponding to the label data according to the number of the text line rows included in each page of the file and the number of characters included in each text line, and further positioning the label data to the specific text line of each page of the file; and finally, calculating the positions of the first text and the second text corresponding to the label data in the original text file and the comparison text file respectively according to the file page number corresponding to the label data, the text line corresponding to the label data and the label position, namely under the condition that the label data corresponding to each page and the text line specifically corresponding to the label data are known, and specifically obtaining the character offset specifically corresponding to the label data in the corresponding text line according to the label position in the label data. In this way, compared with the direct character-level mapping, the calculation amount in the mapping process can be greatly reduced, and the mapping of the label data is improved.
In addition, the mapping method of the tag data may be performed when the corresponding target file is determined for the tag data according to the tag type, or may be performed when the target file corresponding to the tag data is not determined, and when the target file corresponding to the tag data is not determined, all the tag data may be mapped to the original text file and the comparison text file for display directly according to the tag positions included in the tag data.
