Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
According to an aspect of the embodiment of the present invention, there is provided a document processing method, which may be applied to a user equipment or a server.
As shown in fig. 1, the document processing method may include:
step 101: text blocks in the target layout document are identified.
For the target layout document, the text content in each page is recorded in the form of at least one text block. Wherein each text block includes: a rectangular box (i.e., box) and text content within the rectangular box. The rectangular box may be used to define information such as the location of text content within the box in the page, the space occupied, etc.
According to the embodiment of the invention, the text blocks in the target format document can be identified according to the format grammar corresponding to the target format document. The format of the target format document may be a portable document format (Portable Document Format, PDF for short), or may be other types of format document formats.
Step 102: in the process of converting the target format document into the streaming document, a space character is added between the first text block and the second text block according to the text information of the first text block and the second text block respectively.
The first text block and the second text block are two adjacent text blocks in the reading direction in the target layout document. The first text block and the second text block may be in the same line, or may be two adjacent lines in the same paragraph (for example, the first text block is the last text block in the previous line of the two adjacent lines, and the second text block is the first text block in the next line of the two adjacent lines).
In the embodiment of the invention, whether the space character is added between the first text block and the second text block can be determined according to the text information of the first text block and the second text block respectively. Wherein, the text information described herein may include: at least one of font, font size, and character type of the text. And the character types of the text may include: chinese, english, number, punctuation and operation symbol.
The font, size, character type, etc. of the text may often determine whether adding a space character is necessary. For example, for a character type, when the character types of the text in the first text block and the second text block are english, it is necessary to add a space character between the two text blocks to separate words from each other. For another example, in a layout document, since some space characters are represented by setting positions of text blocks to make a separation distance between adjacent two text blocks, it is possible to determine whether or not a space character needs to be supplemented according to the separation distance between the adjacent two text blocks. The space character width may be different between the texts with different fonts and/or character sizes, so that the spacing distance used for representing the space character is also different, and therefore, whether the spacing distance between two text blocks is used for representing the space character or not can be determined according to the fonts and/or character sizes of the texts, and if the space character is represented, the space character needs to be supplemented; if the space character is not represented, no supplemental space character is needed.
In summary, in the embodiment of the present invention, in the process of converting a format document into a streaming document, whether a space symbol needs to be added between two adjacent text blocks or not may be determined according to text information of the two adjacent text blocks, and the space symbol is added when the space symbol needs to be added, so as to reduce the problem that a sentence is difficult to break when a user reads due to lack of the space symbol.
According to another aspect of the embodiment of the present invention, a document processing method is provided, which may be applied to a user device or a server.
As shown in fig. 2, the document processing method includes:
step 201: text blocks in the target layout document are identified.
For the target layout document, the text content in each page is recorded in the form of at least one text block. Wherein each text block includes: a rectangular box (i.e., box) and text content within the rectangular box. The rectangular box may be used to define information such as the location of text content within the box in the page, the space occupied, etc.
According to the embodiment of the invention, the text blocks in the target format document can be identified according to the format grammar corresponding to the target format document. The format of the target format document can be a portable document format or other types of format document formats.
Step 202: in the process of converting the target format document into the streaming document, determining the reference space width between the first text block and the second text block according to the text information of the first text block and the second text block respectively.
The first text block and the second text block are two adjacent text blocks in the reading direction in the target layout document, and the first text block and the second text block are in the same row.
In the embodiment of the invention, the reference space width between the first text block and the second text block can be determined according to the text information of the first text block and the second text block respectively. Wherein, the text information described herein may include: at least one of font, font size, and character type of the text. And the character types of the text may include: chinese, english, number, punctuation and operation symbol.
When at least two reference space widths can be determined according to the text information of the first text block and the text information of the second text block, the reference space width with the smallest numerical value can be taken as the reference space width between the first text block and the second text block so as to reduce omission of space characters and add the space characters to the greatest extent. For example, according to the text information of the first text block and the text information of the second text block, two different values of reference space widths, namely m and n, can be determined, and at this time, the minimum value of m and n is taken as the reference space width between the first text block and the second text block.
Step 203: in the case where the separation distance between the first text block and the second text block is greater than or equal to the reference space width, a space character is added between the first text block and the second text block.
After determining a reference space width between the first text block and the second text block, a separation distance between the first text block and the second text block is compared to the reference space width. If the separation distance is greater than or equal to the reference space width, the separation distance is considered to represent a space character, and it is determined that a space character is added between the first text block and the second text block. If the separation distance is less than the reference space width, the separation distance is considered to be not indicative of a space character, and it is determined that no space character needs to be added between the first text block and the second text block.
For a better understanding of the flow of adding a space character, the text content shown in fig. 3 is exemplified below.
The a-graph in fig. 3 illustrates a piece of text content in a target layout document. In the process of converting the target format document into the stream document, the text content is identified, the text block corresponding to the text content is determined, and the number of the text blocks corresponding to the text content is 6 as shown in the b diagram in fig. 3, and the text blocks are respectively: the text content "english master copy" corresponds to one text block, the text content "O' reily" corresponds to one text block, the text content "Media", the text content "inc." corresponds to one text block, the text content "publication" corresponds to one text block, the text content "2011". "corresponds to a block of text". After the recognition is completed, extraction analysis is performed on the text content to determine which positions require addition of a space character. The c-chart in fig. 3 illustrates the position in the text content of the segment where the space character needs to be added, and the black dot above the lower line in the c-chart indicates that the space character should be added at the position where the black dot is located. After determining which places in the piece of text content require adding space characters, adding space characters at corresponding positions. The d-diagram in fig. 3 illustrates the typesetting effect of the text content after converting the target layout document into a stream document, wherein the gray rectangles in the diagram illustrate the space characters between the text content.
In the embodiment of the invention, in the process of converting the format document into the streaming document, the reference space width between two adjacent text blocks can be determined according to the text information of the two adjacent text blocks respectively. And comparing the interval distance between two adjacent text blocks with the reference space width, determining whether a space character needs to be supplemented between the two adjacent text blocks according to the comparison result, and adding the space character when the space character needs to be supplemented so as to reduce the problem that the user is difficult to break sentences when reading due to the lack of the space character.
Optionally, in the embodiment of the present invention, before determining whether to add a space character between two adjacent text blocks according to the text information of the text blocks (for example, before determining the reference space width between the first text block and the second text block according to the text information of the first text block and the second text block, respectively), whether a space character is set between the first text block and the second text block may be determined first. If a space symbol is provided, it is described that the space symbol is not required to be added, namely: judging whether to add a space character or not according to the text information; if the space character is not set, whether the space character is added is judged according to the text information. Therefore, the situation that whether the space character is added or not is judged according to the text information can be eliminated, the processing time is saved, and the processing efficiency is improved.
Wherein, can adopt the mode of extracting text content, judge whether to set up the space character between two adjacent text blocks. If a space character can be extracted, a space character is set in the description, and if a space character cannot be extracted, a space character is not set in the description.
Optionally, step 202: determining a reference space width between the first text block and the second text block based on text information of the first text block and the second text block, respectively, may include:
step one: and determining the target space width according to the fonts and/or the word sizes of the texts in the first text block and the second text block respectively.
Different fonts and/or font sizes (i.e., different fonts, different font sizes and different font and font size combinations) may correspond to different preset space widths, for example, the preset space width corresponding to "regular script number four" is 0.5mm, the preset space width corresponding to "regular script number one" is 0.6mm, the preset space width corresponding to "Song body number four" is 0.4mm, and so on. The preset space width described herein may also be understood as a standard space width corresponding to a font and/or a font size. Based on the above, the embodiment of the invention can determine the target space width according to the fonts and/or the word sizes of the texts in the first text block and the second text block respectively.
Wherein, the target space width is: and determining the space width with smaller value in the two space widths according to the fonts and/or the word sizes of the texts in the first text block and the second text block respectively. In the embodiment of the invention, when the space width corresponding to the font and/or the font size of the text in the first text block is different from the space width corresponding to the font and/or the font size of the text in the second text block, the rule of taking the small rule is selected. For example, according to preset corresponding relations between different fonts and/or word sizes and space widths, determining a first space width corresponding to the fonts and/or word sizes of the texts in the first text block and a second space width corresponding to the fonts and/or word sizes of the texts in the second text block respectively; and then determining the space width with smaller value of the first space width and the second space width as the target space width.
When determining the space widths corresponding to two adjacent text blocks, the method is performed according to the same text information. For example, space widths corresponding to fonts and font sizes of text within a block of text are each determined, space widths corresponding to font sizes of text within a block of text are each determined, or space widths corresponding to a combination of fonts and font sizes of text are each determined.
Step two: and determining the target space width ratio value according to the character types of the texts in the first text block and the second text block.
In the layout document creation process, there may be a case where the space distance representing the space character is compressed. In addition, boxes of english, numerals, punctuation marks may be larger than the actual space occupied by characters, and there may be a leading space or a trailing space, so that when a layout document is produced, there may be a case where the space distance for representing a space symbol is compressed by adjusting the position of a text block. In both cases, the actual distance between two adjacent text blocks is smaller than the distance corresponding to the space symbol, which affects the judgment of whether to add the space symbol or not according to the distance between the two adjacent text blocks. Wherein, different characters have different font space distribution, and the compressible space is different in size, so that the size of the compressed space can be determined according to the character types in the text block.
In the embodiment of the present invention, in order to avoid the above situation as much as possible from determining whether to add a space character, different space width ratio parameters (i.e., space width ratio values) are set for different character types, so in the embodiment of the present invention, the target space width ratio value may be determined according to the character type of the text in the first text block and the character type of the text in the second text block, respectively. The target space width ratio value is: and determining the space width ratio value with smaller numerical value in the two space width ratio values according to the character types of texts in the first text block and the second text block respectively.
In the embodiment of the invention, when the space width ratio value corresponding to the character type of the text in the first text block is different from the space width ratio value corresponding to the character type of the text in the second text block, the rule of taking the space width ratio value is selected. For example, according to a preset corresponding relation between different text types and space width ratio values, a first space width ratio value corresponding to the character type of the text in the first text block and a second space width ratio value corresponding to the character type of the text in the second text block are respectively determined; and determining the space width ratio value with the smaller numerical value of the first space width ratio value and the second space width ratio value as the target space width ratio value.
Optionally, in the case that a text of at least two character types is included in one text block, determining a space width ratio value of which the value in the space width ratio values respectively corresponding to the at least two character types is the smallest as the space width ratio value corresponding to the character type of the text in the text block.
Alternatively, when a text block includes text of at least two character types, the corresponding space width ratio value in each text block may be determined according to the character type of the first character or the character type of the last character in the text block. For example, in the reading direction, the first text block precedes the second text block, and the space width ratio value corresponding to the character type of the last character in the first text block may be determined as the space width ratio value corresponding to the character type of the text in the first text block; for the second text block, the space width ratio value corresponding to the character type of the first character in the second text block can be determined as the space width ratio value corresponding to the character type of the text in the second text block.
Step three: the product of the target space width and the target space width ratio value is determined as a reference space width between the first text block and the second text block.
After the target space width to target space width ratio value is obtained, the product of the target space width and the target space width ratio value is determined as the reference space width between the first text block and the second text block. By such processing, the value of the reference space width for determining whether to add a space symbol can be reduced, and the addition of a space symbol can be performed to the maximum extent.
In summary, in the embodiment of the present invention, in the process of converting a format document into a streaming document, for two adjacent text blocks in the same line, the distance between the two adjacent text blocks may be compared with the reference space width, and whether to supplement a space symbol between the two adjacent text blocks is determined according to the comparison result, and when the space symbol is needed to be supplemented, the space symbol is added, so as to reduce the problem that the user is difficult to break the sentence when reading due to lack of the space symbol.
According to another aspect of the embodiment of the present invention, a document processing method is provided, which may be applied to a user device or a server.
As shown in fig. 4, the document processing method includes:
step 401: text blocks in the target layout document are identified.
For the target layout document, the text content in each page is recorded in the form of at least one text block. Wherein each text block includes: a rectangular box (i.e., box) and text content within the rectangular box. The rectangular box may be used to define information such as the location of text content within the box in the page, the space occupied, etc.
According to the embodiment of the invention, the text blocks in the target format document can be identified according to the format grammar corresponding to the target format document. The format of the target format document can be a portable document format or other types of format document formats.
Step 402: in the process of converting the target format document into the stream document, if the character type of the last character in the first text block is the target character type and/or if the character type of the first character in the second text block is the target character type, a space character is added between the first text block and the second text block.
The first text block and the second text block are two text blocks adjacent to each other in the reading direction in the target layout document, and the first text block and the second text block are respectively located in two adjacent lines in the same paragraph, for example, the first text block is the last text block of the previous line in the two adjacent lines, and the second text block is the first text block of the next line in the two adjacent lines.
For two text blocks that are respectively located in two adjacent lines of the same paragraph and are adjacent in the reading direction, since text contents in the two adjacent text blocks may be located in the same line or the same column in the streaming document after the format document is converted into the streaming document, it is also necessary to determine in advance whether a space character needs to be added between the two adjacent text blocks in order to ensure the separation that should be present between the two text contents. The embodiment of the invention can be provided with: in the case that the character type of the last character in the first text block is the target character type and/or in the case that the character type of the first character in the second text block is the target character type, it is determined to add a space character between the first text block and the second text block. The character types of text described herein may include: chinese, english, number, punctuation and operation symbol. The target character types described herein may include: at least one of English and number.
For a better understanding of the flow of adding a space character, the text content shown in fig. 5 is exemplified below.
As shown in fig. 5, a diagram a in fig. 5 illustrates a piece of text content in a target layout document. And in the process of converting the target format document into the streaming document, identifying the text content, and determining a text block corresponding to the text content. The last text block in the first line of the piece of text content (i.e. text block a corresponding to text content "O' reproduction", hereinafter) and the first text block in the second line (i.e. text content "Media", corresponding to text block, hereinafter text block b) are illustrated in fig. 5 b. After the recognition is completed, the text content is extracted and analyzed to determine whether a space character needs to be added between the text block a and the text block b. The graph c in fig. 5 illustrates that a space character needs to be added between the text block a and the text block b, and the black dot above the lower line in the graph c indicates that the space character should be added at the position where the black dot is located. After determining that a space character needs to be added between the text block a and the text block b, the space character is added. The d-diagram in fig. 5 illustrates the typesetting effect of the text content after converting the target layout document into a streaming document, wherein the gray rectangles in the diagram illustrate the space characters between the text content "O' reily" and "Media".
In summary, in the embodiment of the present invention, in the process of converting a format document into a streaming document, for two text blocks that are respectively located in two adjacent lines of the same paragraph and are adjacent in the reading direction, whether a space character needs to be supplemented between the two adjacent text blocks or not may be determined according to the character type of the last character in the preceding text block and/or the character type of the first character in the following text block, respectively, in the two adjacent text blocks, and the space character is added when the space character needs to be supplemented, so as to reduce the problem that the user is difficult to break a sentence when reading due to the lack of the space character.
