[0002] For digital documents, in order to improve the speed of finding content and the reading speed, readers usually hope that they can jump to the corresponding text part by clicking on a certain table of contents item or page reference information in the text. For this purpose, a table of contents page is usually set in the document. The main purpose of setting the table of contents is to facilitate readers to have a general understanding of the content and structure of the full text before reading the document. When readers need to further understand a certain part of the content, they can rely on the table of contents to save the time for finding the document page.

[0048] The term "and / or" is a description of the association relationship of objects and indicates that three relationships can exist. For example, A and / or B means: A or B, or, the three relationships of A and B.

[0049] The term "corresponding" may refer to an association relationship or a binding relationship. That A corresponds to B means there is an association relationship or a binding relationship between A and B.

[0050] As shown in combination with Figure 1 The embodiments of the present disclosure provide a method for page jump, including:

[0051] Step S101, in response to a user's operation instruction in a document, determine the area in the currently displayed document page corresponding to the operation instruction;

[0052] Step S102, identify the characters in the area corresponding to the operation instruction;

[0053] Step S103, in the case where a first feature string exists in the identified characters, determine the target page corresponding to the first feature string in the document;

[0054] Step S104, jump from the currently displayed document page to the target page.

[0055] By using the method for page jump provided by the embodiments of the present disclosure, it is possible to, in response to a user's operation instruction, determine the area in the currently displayed document page corresponding to the operation instruction; by identifying the characters in the area and in the case where a first feature string exists in the identified characters, determine the target page, and after determining the target page, further realize jumping from the currently displayed document page to the target page. By adopting the above method, even when there is no pre-set jump link in the document, it is also possible to identify the feature string in the area corresponding to the user operation instruction by character recognition and determine the target page corresponding to the feature string, thereby realizing page jump.

[0056] Optionally, the document includes a word document, a PDF document, etc. Optionally, the operation instruction includes a click instruction, and the area corresponding to the operation instruction is the click area corresponding to the click instruction.

[0057] Optionally, the first feature string includes one or more of a string for characterizing a document chapter, a string for characterizing a chapter title, and a string for characterizing a page reference.

[0058] Optionally, determine the digits at preset positions among the recognized characters as the strings representing the document chapters. In some embodiments, the string representing the document chapter is the digit at the first character position among the recognized characters. For example: if the digit at the first character position among the recognized characters is "1", "1.1", or "1.2.1", then "1", "1.1", or "1.2.1" is determined as the string representing the document chapter. In some embodiments, if the string representing the document chapter is the digit at the first position among the recognized characters, then it is within parentheses. For example: if the digit within parentheses at the first character position among the recognized characters is "(1)", then "(1)" is determined as the string representing the document chapter.

[0059] Optionally, determine the Chinese characters or English characters at set positions among the recognized characters as the strings representing the chapter titles. In some embodiments, the string representing the chapter title is the Chinese character or English character after the string representing the document chapter. For example: if "2.1 Platform and Architecture" is recognized, where "2.1" is the string representing the document chapter, then "Platform and Architecture" is the string representing the chapter title.

[0060] Optionally, determine the string with page reference information as the string representing the page reference. For example: "Refer to page X", "See details on page X", etc.

[0061] In some embodiments, the first feature string is only the string used to represent the document chapter, such as "1", "1.1", or "1.2.1". In some embodiments, the first feature string is only the string used to represent the chapter title, such as "Platform and Architecture". In some embodiments, the first feature string includes the string used to represent the document chapter and the string used to represent the chapter title, such as "2.1 Platform and Architecture". In some embodiments, the first feature string includes the string used to represent the document chapter and the string used to represent the page reference, such as "1.1 Refer to page X" or "Chapter 1.1 Refer to page X". In some embodiments, the first feature string includes the string used to represent the chapter title and the string used to represent the page reference, such as: "Platform and Architecture See details on page X". In some embodiments, the first feature string includes the string used to represent the document chapter, the string used to represent the chapter title, and the string used to represent the page reference, such as: "2.1 Platform and Architecture See details on page X".

[0062] Optionally, determine the area corresponding to the operation instruction in the currently displayed document page, including: detecting whether the currently displayed document page contains a table of contents area; in the case where the currently displayed document page contains a table of contents area, determine the area corresponding to the operation instruction in the table of contents area.

[0063] Combined Figure 2 As shown, in some embodiments, the following method for page jumping is provided:

[0064] S201, in response to a user's operation instruction in a document, detect whether the currently displayed document page contains a table of contents area; if the currently displayed document page contains a table of contents area, perform step S202; if the currently displayed document page does not contain a table of contents area, end the page jump.

[0065] S202, determine the area corresponding to the operation instruction in the table of contents area.

[0066] S203, identify the characters in the area corresponding to the operation instruction.

[0067] S204, if a first feature string exists in the identified characters, determine the target page corresponding to the first feature string in the document.

[0068] S205, jump from the currently displayed document page to the target page, and then end the page jump.

[0069] In this way, without adding jump links to the table of contents area of the document, when browsing the table of contents area of the document, it is also possible to perform feature string recognition on the area corresponding to the user's operation instruction in the table of contents area of the document, and determine the target page corresponding to the feature string, thereby realizing the jump from the table of contents area to the body text page, making it more convenient for users to consult the document.

[0070] Optionally, detecting whether the currently displayed document page contains a table of contents area includes:

[0071] Determine whether the currently displayed document page includes a preset second feature string; the second feature string is a string characterizing the document table of contents;

[0072] If the currently displayed document page includes a preset second feature string, determine that the currently displayed document page contains a table of contents area;

[0073] If the currently displayed document page does not include a preset second feature string, perform recognition processing on the currently displayed document page to determine whether the currently displayed document page contains a table of contents area.

[0074] Identify the characters in the currently displayed document page. If the preset second feature string is recognized, it is determined that the currently displayed document page includes the preset second feature string; if the preset second feature string is not recognized, it is determined that the currently displayed document page does not include the preset second feature string. Optionally, the second feature string is a preset keyword. In some embodiments, the preset keywords are: "Table of Contents", "Outline", "Content", etc.

[0075] Optionally, perform an identification process on the currently displayed document page to determine whether the currently displayed document page contains a table of contents area, including:

[0076] Determine whether the currently displayed document page is a picture;

[0077] If the currently displayed document page is a picture, perform image recognition on the currently displayed document page to obtain the page text corresponding to the currently displayed document page;

[0078] Determine whether the string in the page text includes the second feature string;

[0079] If the string in the page text includes the second feature string, it is determined that the currently displayed document page contains a table of contents area.

[0080] Optionally, perform image recognition on the currently displayed document page to obtain the page text corresponding to the currently displayed document page, including: using OCR character recognition technology to recognize the characters in the currently displayed document page to obtain the page text corresponding to the currently displayed document page.

[0081] Generally, the document pages in scanned documents are usually pictures. Therefore, it is necessary to perform character recognition on the document pages in picture form to obtain the text information in the pictures, and then determine whether the table of contents area is included according to the strings in the recognized text information. In this way, it is also possible to determine the table of contents area for pages in picture form, improving the success rate of table of contents area recognition, and further improving the success rate of jumping from the table of contents area to the body text page, making it more convenient for users to view documents.

[0082] Combined Figure 3 As shown, in some embodiments, the following method for page jumping is provided:

[0083] S301. In response to a user's operation instruction in the document, determine whether the currently displayed document page includes a preset second feature string. If the currently displayed document page includes the preset second feature string, determine that the currently displayed document page contains a table of contents area and execute step S305. If the currently displayed document page does not include the preset second feature string, execute step S302.

[0084] S302. Determine whether the currently displayed document page is a picture. If the currently displayed document page is a picture, execute step S303. If the currently displayed document page is not a picture, end the page jump.

[0085] S303. Perform image recognition on the currently displayed document page to obtain the page text corresponding to the currently displayed document page, and then execute step S304.

[0086] S304. Determine whether the string in the page text includes the second feature string. If the string in the page text includes the second feature string, determine that the currently displayed document page contains a table of contents area and execute step S305. If the string in the page text does not include the second feature string, end the page jump.

[0087] S305. Determine the area corresponding to the operation instruction in the table of contents area, and then execute step S306.

[0088] S306. Recognize the characters in the area corresponding to the operation instruction, and then execute step S307.

[0089] S307. If a first feature string exists in the recognized characters, determine the target page corresponding to the first feature string in the document, and then execute step S308.

[0090] S308. Jump from the currently displayed document page to the target page, and then end the page jump.

[0091] Optionally, determining the target page corresponding to the first feature string in the document includes: detecting whether there are numbers in the area corresponding to the operation instruction; if there are numbers, determine the target page corresponding to the first feature string according to the numbers; if there are no numbers, determine the target page corresponding to the first feature string according to a preset matching strategy.

[0092] In this way, regardless of whether there are numbers in the area corresponding to the operation instruction, the target page can be determined, thereby providing a jump basis for realizing the jump from the currently displayed document page to the target page.

[0093] Optionally, detect whether there is a number in the area corresponding to the operation instruction, including: obtaining the string in the area corresponding to the operation instruction, determining whether the characters at the preset number of digits of the string are numeric characters, and if the characters at the preset number of digits of the string are numeric characters, determining that there is a number in the area corresponding to the operation instruction; if the characters at the preset number of digits of the string are not numeric characters, determining that there is no number in the area corresponding to the operation instruction. And determine the number at the preset number of digits in the string as the number for determining the target page. For example, if the characters at the last m digits of the string in the area corresponding to the operation instruction are numeric characters, it is determined that there is a number in the area corresponding to the operation instruction, and the m-digit number is determined as the page number of the target page to be jumped to, where m is a positive integer.

[0094] Combined with Figure 4 As shown, in some embodiments, the following method for page jumping is provided:

[0095] S401, in response to the user's operation instruction in the document, determine the area corresponding to the operation instruction in the currently displayed document page.

[0096] S402, identify the characters in the area corresponding to the operation instruction.

[0097] S403, determine whether there is a first feature string in the identified characters. If there is a first feature string in the identified characters, execute step S404; if there is no first feature string in the identified characters, end the page jump. The first feature string includes one or more of a string for characterizing a document chapter, a string for characterizing a chapter title, and a string for characterizing a page reference.

[0098] S404, detect whether there is a number in the area corresponding to the operation instruction. If there is a number, execute step S405; if there is no number, execute step S406.

[0099] S405, determine the target page according to the number, and then execute step S407.

[0100] S406, determine the target page according to the preset matching strategy, and then execute step S407.

[0101] S407, jump from the currently displayed document page to the target page, and then end the page jump.

[0102] In this way, without adding jump links to the table of contents page of the document, when browsing the table of contents page of the document, it is also possible to perform string recognition in the table of contents page part of the document according to the area corresponding to the user's operation instruction. In the presence of the first feature string, page jumping is achieved, simplifying the jump function steps and making it more convenient for users to access the document.

[0103] Optionally, determining the target page according to the number includes: detecting the page number area of each document page; for the document pages with page number areas, identifying the page number information in the page number area; and determining the page with the same page number information as the number in the area corresponding to the operation instruction as the target page corresponding to the first feature string.

[0104] In this way, it is convenient to determine the page corresponding to the number in the area corresponding to the operation instruction, thereby providing a jump basis for realizing the jump from the currently displayed document page to the target page.

[0105] Optionally, if there are page numbers in the preset area of each document page, then determine the preset area of the document page as the page number area. For example, if there are page numbers at the bottom / top of the document page, then determine the bottom / top of the document page containing the page numbers as the page number area.

[0106] Optionally, after detecting the page number area of each document page, it further includes: for the document pages without page number areas, obtaining the page index position corresponding to the first feature string; and determining the page corresponding to the page index position as the target page. In this way, for the situation where the document page has no page number area or page number information, a method for realizing page jumping is provided, increasing the success rate of page jumping.

[0107] Optionally, obtaining the page index position corresponding to the first feature string includes: starting from the preset page in the document and counting, and determining the page when the count reaches the number in the area corresponding to the operation instruction as the page index position. Optionally, the preset page is the first page of the document.

[0108] Combined with Figure 5 As shown in the following, in some embodiments, the following method for page jumping is provided:

[0109] S501, in response to the user's operation instruction in the document, determine the area corresponding to the operation instruction in the currently displayed document page.

[0110] S502, identify the characters in the area corresponding to the operation instruction.

[0111] S503. Determine whether there is a first feature string among the recognized characters. If there is a first feature string among the recognized characters, execute step S504; if there is no first feature string among the recognized characters, end the page jump. The first feature string includes one or more of a string for characterizing a document chapter, a string for characterizing a chapter title, and a string for characterizing a page reference.

[0112] S504. Detect whether there are numbers in the area corresponding to the operation instruction. If there are numbers, execute step S505; if there are no numbers, execute step S508.

[0113] S505. Detect whether there is a page number area on each document page; if there is a page number area on the document page, execute step S506, if there is no page number area on the document page, execute step S507.

[0114] S506. Identify the page number information in the page number area; determine the page with the same page number as the number as the target page, and then execute step S509.

[0115] S507. Obtain the page index position corresponding to the first feature string; determine the page corresponding to the page index position as the target page, and then execute step S509.

[0116] S508. Determine the target page according to the preset matching strategy, and then execute step S509.

[0117] S509. Jump from the currently displayed document page to the target page, and then end the page jump.

[0118] In this way, without pre-adding jump links to the document, during document browsing, string recognition is performed on the area corresponding to the user's operation instruction. When there is a first feature string, page jump is achieved according to the number in the area corresponding to the operation instruction or according to the preset matching strategy, simplifying the jump function steps and making it more convenient for users to consult the document.

[0119] Optionally, determining the target page according to the preset matching strategy includes: determining one or more document pages to be detected; detecting whether there is a first feature string in the one or more document pages to be detected; determining the document page with the first feature string as the target page.

[0120] In this way, page jump can be achieved only through the first feature string, increasing the success rate of page jump.

[0121] Optionally, when there are multiple document pages to be detected that contain the first feature string, randomly select one document page from the multiple document pages containing the first feature string and determine it as the target page, or select the document page closest to the currently displayed document page from the multiple document pages containing the first feature string and determine it as the target page.

[0122] Optionally, the document pages to be detected may include the currently displayed document page, or may not include the currently displayed document page. For example, when the number of document pages to be detected exceeds a preset threshold, the document pages to be detected do not include the currently displayed document page. In this way, detection resources can be saved. When the number of document pages to be detected does not exceed the preset threshold, the document pages to be detected include the currently displayed document page. In this way, the accuracy of detection can be improved.

[0123] Optionally, determining one or more document pages to be detected includes: obtaining the number of document pages; when the number of document pages is greater than N, obtaining N document pages and determining the obtained N document pages as the document pages to be detected; or, when the number of document pages is less than or equal to N, taking all document pages as the document pages to be detected; where N is a preset positive integer. In this way, since the maximum matching range for obtaining the document pages to be detected is set, infinite matching can be prevented, and the efficiency of implementing page jumps is improved.

[0124] Optionally, take the N pages after / before the currently displayed document page as the document pages to be detected. Optionally, when the number of pages after / before the currently displayed document page is less than N, take all the pages after / before the currently displayed document page as the document pages to be detected. Optionally, N is a preset fixed value, and in some embodiments, 1 ≤ N ≤ 20.

[0125] Optionally, obtain the chapter corresponding to the string characterizing the document chapter in the area corresponding to the operation instruction, obtain the number of document pages corresponding to this chapter, when the number of document pages corresponding to this chapter is greater than N, obtain N document pages and determine the obtained N document pages as the document pages to be detected; or, when the number of document pages corresponding to this chapter is less than or equal to N, take all the document pages corresponding to this chapter as the document pages to be detected. For example, the document pages corresponding to the second chapter are pages 24 to 36, which do not exceed 20 pages, then pages 24 to 36 are all determined as the document pages to be detected.

[0126] Combined with Figure 6 As shown, in some embodiments, the following method for page jumping is provided:

[0127] S601. In response to a user's operation instruction in a document, determine the area in the currently displayed document page corresponding to the operation instruction.

[0128] S602. Identify the characters in the area corresponding to the operation instruction.

[0129] S603. Determine whether a first feature string exists in the identified characters. If the first feature string exists in the identified characters, execute step S604; if the first feature string does not exist in the identified characters, end the page jump. The first feature string includes one or more of a string for characterizing a document chapter, a string for characterizing a chapter title, and a string for characterizing a page reference.

[0130] S604. Detect whether there are numbers in the area corresponding to the operation instruction. If there are numbers, execute step S605; if there are no numbers, execute step S608.

[0131] S605. Detect whether there is a page number area on each document page; if there is a page number area on the document page, execute step S606; if there is no page number area on the document page, execute step S607.

[0132] S606. Identify the page number information in the page number area; determine the page with the same page number information as the number as the target page, and then execute step S610.

[0133] S607. Obtain the page index position corresponding to the first feature string; determine the page corresponding to the page index position as the target page, and then execute step S610.

[0134] S608.

[0135] S609. Determine the document page with the first feature string as the target page, and then execute step S610.

[0136] S610. Jump from the currently displayed document page to the target page, and then end the page jump.

[0137] In this way, without adding jump links to the table of contents page of the document, when browsing the table of contents page of the document, string recognition can also be performed in the table of contents page section of the document according to the area corresponding to the user's operation instruction. In the presence of the first feature string, page jumping is achieved according to the numbers in the area corresponding to the operation instruction, or according to whether the first feature string exists in the document page to be detected, simplifying the jump function steps and making it more convenient for users to consult the document.

[0138] As shown in combination with Figure 7 In some embodiments, the following method for PDF document page jumping is provided:

[0139] S701, in response to a user's click instruction on a PDF page in the document, determine whether the currently displayed PDF page includes a preset second feature string; if the currently displayed PDF page includes the preset second feature string, determine that the currently displayed PDF page contains a table of contents area and execute step S705; if the currently displayed PDF page does not include the preset second feature string, execute step S702.

[0140] S702, determine whether the currently displayed PDF page is a picture; if the currently displayed PDF page is a picture, execute step S703; if the currently displayed PDF page is not a picture, end the page jump.

[0141] S703, perform image recognition on the currently displayed PDF page to obtain the page text corresponding to the currently displayed PDF page, and then execute step S704.

[0142] S704, determine whether the string in the page text includes the second feature string; if the string in the page text includes the second feature string, determine that the currently displayed PDF page contains a table of contents area and execute step S705. If the string in the page text does not include the second feature string, end the page jump.

[0143] S705, determine the click area corresponding to the click instruction in the table of contents area, and then execute step S706.

[0144] S706, recognize the characters in the click area, and then execute step S707.

[0145] S707, determine whether there is a string for characterizing the document chapter among the recognized characters. If there is a string for characterizing the document chapter among the recognized characters, execute step S708; if there is no string for characterizing the document chapter among the recognized characters, end the page jump.

[0146] S708. Determine whether there is a string for characterizing the chapter title among the recognized characters. If there is a string for characterizing the chapter title among the recognized characters, execute step S709; if there is no string for characterizing the chapter title among the recognized characters, end the page jump.

[0147] S709. Detect whether there are numbers in the click area. If there are numbers, execute step S710; if there are no numbers, execute step S713.

[0148] S710. Detect whether there is a page number area on each PDF page; if there is a page number area on each PDF page, execute step S711, if there is no page number area on the PDF page, execute step S712.

[0149] S711. Identify the page number information in the page number area; determine the page with the same page number information as the number in the click area as the target page, and then execute step S715.

[0150] S712. Obtain the page index position corresponding to the first feature string; determine the page corresponding to the page index position as the target page, and then execute step S715.

[0151] S713. Determine one or more PDF pages to be detected; detect whether there is a first feature string in the one or more PDF pages to be detected; if there is a first feature string in the PDF page to be detected, execute step S714; if there is no first feature string in the PDF page to be detected, end the page jump.

[0152] S714. Determine the target page according to the PDF page where the first feature string exists, and then execute step S715.

[0153] S715. Jump from the currently displayed PDF page to the target page, and then end the page jump.

[0154] In this way, without pre-adding jump links to the table of contents page of the PDF document, when browsing the table of contents area of the PDF document, it is also possible to perform string recognition in the table of contents section of the PDF document according to the click area corresponding to the user's click instruction, and then implement page jump, making it more convenient for users to view the PDF document. In the above embodiment, by determining whether the currently displayed PDF page includes a preset second feature string, and at the same time performing image recognition for the case where the currently displayed PDF page is a picture and characters cannot be directly recognized, and then performing character recognition on the text obtained by the image recognition, to determine whether the currently displayed PDF page contains a table of contents area, this can improve the recognition probability of the table of contents area and avoid ineffective recognition of the table of contents area. After recognizing whether the currently displayed PDF page contains a table of contents area, recognize the characters in the click area, first determine the string representing the document chapter, and then determine the string representing the chapter title. In the case where there are strings representing the document chapter and strings representing the chapter title, then determine the numbers in the click area and perform page jump, which improves the probability that the information recognized in the click area is table of contents entry information, and the page jump is more in line with the user's operation purpose. The above embodiment can not only match the page number information in the PDF page for page jump, but also perform page jump through the page index position corresponding to the first feature string in the click area when there is no page number information in the PDF page, and can also match the pages containing the first feature string in each PDF page of the PDF document for page jump. Since multiple jump methods are provided, the success rate of page jump is improved.
