A handwriting-based note generation method, an electronic device and a storage medium

[0016] Example one

[0017] figure 1 It shows a schematic flow chart of a method for generating notes based on handwriting handwriting provided in the first embodiment of the present invention, which is used to extract the core knowledge points marked in the process of reading the e-book by the user. Such as figure 1 As shown, the note generation method based on handwriting includes:

[0018] In step S101, extract each original text abstract from the e-book according to the handwriting of the user in the process of reading the e-book.

[0019] The handwriting includes at least one or more of circle, line, abstract identifier, and handwritten text. For handwriting as circle or line, the original content of the user's circle or line can be directly used as the original text; for handwriting as handwritten text, the content of the handwritten text is recognized and based on the original content of the handwritten text and e-book The relative position determines that the original content associated with the handwritten text is the original abstract; for handwriting as the abstract identifier, if it is detected that the abstract identifier is drawn in the e-book, the text located at the abstract identifier will be used as the original abstract, where The abstract identifier can be a triangle symbol, a star symbol, etc., and based on preset rules, different abstract identifiers can represent the importance of the original text abstract, so that the typesetting information of each original abstract can be determined according to the importance. . In this way, by extracting the original text abstract corresponding to the handwriting, it can be ensured that all the core knowledge points of the e-book that the user thinks are extracted, so that the user will not miss the knowledge points when learning through the extracted original text abstract later.

[0020] Step S102: Determine the hierarchical relationship between the original text abstracts, and determine the typesetting information of each original text abstract.

[0021] Exemplarily, when determining the hierarchical relationship between the original text abstracts, the hierarchical relationship of the chapters of each original text abstract in the e-book may be based on the detailed catalog of the e-book as the hierarchical relationship of each original text abstract. Further, the number of pages and paragraphs of the original abstract can also be used as a supplement, and also as a hierarchical relationship of the original abstract. In addition, since the abstract identifiers are all associated with levels, the hierarchical relationship of the abstract identifiers associated with each abstract original text can be used as the hierarchical relationship of each abstract original text. Therefore, by determining the hierarchical relationship between the original text abstracts, the relevance between the original text abstracts can be ensured, and thus the user can be more organized in learning.

[0022] Before determining the typesetting information of each original text abstract, the association relationship between the candidate identifier and the candidate typesetting information is determined in advance, where the typesetting information includes at least one of the font, font size, bolding and color of the text. Exemplarily, candidate identifiers are divided into multiple levels according to their importance, and each level corresponds to different typesetting information. For example, the typesetting information of the first-level candidate identifier is "No. 3 Song Ti, bold, and red", except for this. For more important candidate identifiers, the corresponding typesetting information can optionally include highlighting in different colors.

[0023] When determining the typesetting information of each original text abstract, the abstract identifier associated with each original text abstract is matched with the association relationship between the candidate identifier and the candidate typesetting information to determine the typesetting information of the original text abstract. That is, the abstract identifier associated with any original text abstract is matched with the candidate identifier, and the typesetting information corresponding to the candidate identifier that matches the abstract identifier is used as the typesetting information of the original text abstract. By displaying the original text abstracts in different layouts, it is convenient for users to clarify the importance of each original text abstract when learning, and then learn more specifically.

[0024] Step S103, according to the hierarchical relationship between the original text abstracts and the typesetting information of each original text abstract, an abstract note including the content of the original text abstract is generated.

[0025] Based on the above steps, a summary note including the content of the original abstract can be generated directly according to the hierarchical relationship between the original abstracts and the typesetting information of each original abstract, and displayed on the abstract note display interface for users to view.

[0026] Further, there may be original text abstracts with parallel hierarchical relationships in the determined original text abstracts, such as the original text abstracts corresponding to the abstract identifiers "①, ②, ③...". Therefore, before generating summary notes, it is necessary to check the parallel hierarchical relationships. The original abstract is processed as follows:

[0027] S1: If at least two original text abstracts are in a parallel hierarchical relationship, determine the parent title of the at least two original text abstracts.

[0028] Exemplarily, if the at least two original text abstracts belong to the same chapter, then the chapter name is used as the parent title; otherwise, text processing technology and content recognition technology can be used to extract the public key from the at least two original text abstracts Words, using a common keyword as the parent title; or, recognizing handwriting text from the handwriting associated with the at least two original text abstracts, and using the recognized handwriting text as the parent title.

[0029] S2, using the at least two original text abstracts as the node content of the parallel connector, and using typesetting information to typeset the node content.

[0030] The typesetting information of the node content can be determined according to the above step S102, which will not be repeated here.

[0031] S3. Use the parent title as the name of the parallel connector.

[0032] After the original text summaries of the parallel hierarchical relationship are processed through steps S1-S3, the hierarchical relationship in the generated summary notes generated according to step S103 is clear, and the readability and organization of the summary notes are increased.

[0033] According to the handwriting-based note generation method of the present invention, on the basis of obtaining the original text abstract by using the handwriting handwriting, an abstract note is generated for the user according to the determined hierarchical relationship and typesetting information of the original text abstract. As a result, it is possible to extract the marked core content from the e-book read by the user and present it to the user in the form of summary notes, so that the user can learn through the summary notes to improve the user's learning efficiency.

[0034] Example two

[0035] figure 2 It shows a flowchart of a method for generating notes based on handwriting in the second embodiment of the present invention. This embodiment is applied to the situation of using the generated summary notes, such as figure 2 As shown, the method includes:

[0036] Step S201, extracting each original text abstract from the e-book according to the handwriting of the user in the process of reading the e-book.

[0037] Step S202: Determine the hierarchical relationship between the original text abstracts, and determine the typesetting information of each original text abstract.

[0038] Step S203: According to the hierarchical relationship between the original text abstracts and the typesetting information of each original text abstract, an abstract note including the content of the original text abstract is generated.

[0039] After the summary note is generated, it can be displayed on the summary note display interface. In addition, the abstract note and the original text of the e-book can be switched through an index relationship. For details, refer to steps S204 and S205. It is also possible to perform corresponding functions by operating other controls on the summary note display interface, such as step S206. In this embodiment, there is no sequence between S204, S205 and S206.

[0040] In step S204, if a touch operation acting on any text summary in the summary note display interface is monitored, link to the original text of the e-book associated with the text summary.

[0041] In this embodiment, by detecting the position coordinates of the user's touch operation in the summary note display interface, the original text abstract to be operated by the user can be determined, and based on the index relationship of the pre-stored original text abstract, link to the e-book associated with the original text abstract original.

[0042] Step S205: If a touch operation acting on any handwriting in the e-book is monitored, link to the original abstract in the summary note associated with the handwriting.

[0043] By detecting the position coordinates of the user's touch operation on the original text interface of the e-book, the handwritten note to be operated by the user is determined, and the handwritten note is linked to the original abstract associated with the handwritten handwriting in the abstract note. Therefore, the browsing efficiency can be improved by switching between the summary notes and the original text of the e-book.

[0044] Step S206: If a touch operation acting on the handwriting identifier of any original text summary in the summary note display interface is monitored, a screenshot of the handwriting handwriting in the e-book of the original text summary is obtained, and the summary note display interface is displayed. Screenshot of handwriting.

[0045] In the summary note display interface, a handwriting identifier is set at each text summary, and the handwriting identifier may be a highlighted bubble or dot. In response to the user's operation of touching the note identifier of a certain original text abstract, the handwriting screenshot of the original text abstract in the e-book is obtained. The handwriting screenshot is taken during the process of the user's handwriting mark. By recognizing the handwriting, the range of the handwriting is determined, and then screenshots of the handwriting within the determined range are taken, where the handwriting is preferably the user's handwritten text. Moreover, the obtained handwriting screenshots can also be displayed in the summary note display interface, so that the original text summary and its corresponding handwriting screenshots can be displayed on the summary note display interface at the same time, and the learning efficiency of users can be improved through comparative learning.

[0046] According to the handwriting-based note generation method of the present invention, according to the user's touch operation, it is possible to quickly switch between the summary note and the original text of the e-book, and through the touch handwriting identifier, the handwriting can be screenshots and corresponded to the original text The summary is displayed on the summary note display interface at the same time, so that the user can compare and view the learning, thereby improving the user's learning efficiency.

[0047] Example three

[0048] image 3 It shows a flowchart of a method for generating notes based on handwriting in the third embodiment of the present invention. This embodiment is applied to a situation where abstract notes of different e-books are merged, such as image 3 As shown, the method includes:

[0049] Step S301: According to the user's handwriting in the process of reading the e-book, extract each original text abstract from the e-book.

[0050] Step S302: Determine the hierarchical relationship between the original text abstracts, and determine the typesetting information of each original text abstract.

[0051] Step S303: According to the hierarchical relationship between the original text abstracts and the typesetting information of each original text abstract, an abstract note including the content of the original text abstract is generated.

[0052] In this embodiment, after the summary note is generated, it can be displayed on the summary note display interface, and the summary note display interface provides a sharing control so that the user can share the generated summary note with others through the sharing control so that others can directly Learn based on the summary notes without reading the entire e-book, thereby improving the learning efficiency of the people who use the summary notes. In addition, the summary notes of different books can be merged, see S304 for details.

[0053] Step S304: In response to the note fusion request of other e-books, integrate the part of the summary notes to be merged into the summary notes of the current e-book.

[0054] Specifically, in response to the note fusion request of other e-books, determine the relevance of the summary note part of other e-books to be merged with the original abstract in the summary note of the current e-book, and add the summary note part to the current e-book The most relevant source abstract in the abstract notes of the book. For example, other e-books and current e-books are both legal books, and the summary notes of other e-books to be integrated are the legal definition of the term "being brave to do what is right". If the summary notes of the current e-book contain more than one target source text abstract If it involves "being brave for righteousness", it is determined that the part of the summary notes to be merged is strongly related to the target original text abstract in the current e-book, and the legal definition of the term "being brave for righteousness" can be added to the target source text abstract. It is ensured that users can further understand the meaning of the target source text abstract after seeing the legal definition of the term "being brave to do what is right", thereby ensuring the efficiency of user learning.

[0055] According to the handwriting-based note generation method of the present invention, after the summary note is generated, in addition to sharing, part of the summary notes of other books can also be added to the relevant original abstract in the summary note of the current e-book, so that users can Combined with the newly added note content, deepen the understanding of the original text summary of the current e-book, thereby ensuring the efficiency of user learning.

[0056] In one embodiment of the present invention, the method for generating notes based on handwriting is applied to an e-book reader, which displays the content of the book through an ink (e-ink) screen, and has a built-in electromagnetic board. To receive the handwriting electromagnetic signal triggered by the handwriting electromagnetic pen on the ink screen, and convert the electromagnetic signal into handwriting handwriting, which is superimposed on the book content and displayed in the ink screen.
