With continued reference to FIG. 2, a flow diagram 200 of one embodiment of a method for relocation of user annotation data in an electronic book is shown, in accordance with the present application. The user marked data repositioning method in the electronic book comprises the following steps:
In some alternative implementations, the to-be-updated version of the electronic book may be a latest version of the electronic book, and the current version of the electronic book may be an earlier version stored locally (e.g., the terminal device shown in fig. 1).
And step 220, generating an update chain of the electronic book based on the version information of the version to be updated and the version information of the current version to obtain a location update file from the current version to the version to be updated of the electronic book, wherein the update chain comprises location update data of any at least two adjacent versions between the version to be updated and the current version.
In some alternative implementations, the versions of the electronic book may be stored in a server. Each version may include, for example, version information for that version and content information for the version of the electronic book.
Here, the version information may be understood as identity information corresponding to content information of a certain version of the electronic book one by one, for example, a unique version number may be adopted as the version information of a certain version of the electronic book.
In addition, the location update data may be understood as differences of the contents of the two adjacent versions, including but not limited to different locations of the same content in the two adjacent versions, locations of contents added by a newer version in the two adjacent versions, and the like.
In some application scenarios, assuming that an electronic book includes A, B, C versions according to the chronological order of update time, the update chain of the electronic book may include location update data from version a to version B, and location update data from version B to version C, for example.
After getting the location update data in the update chain, the location update data may be merged to get a location update file from the current version of the electronic book to the version to be updated.
Here, the user annotation data may be any mark made to the electronic book by a reader reading the electronic book, including but not limited to an annotation, a mark (e.g., an underline, a wavy line, an accent mark marked on a text of a part of the electronic book) and the like made by the reader at a certain position of the electronic book.
And 240, updating the user annotation data of the current version based on the location updating file, and obtaining the user annotation data corresponding to the version to be updated.
In some embodiments, the location update data may include, for example: the version number of any at least two adjacent versions, the file name of each file content contained in any at least two adjacent versions and mapping data corresponding to the file name; the mapping data comprises position change information of file contents with the same file name in any at least two adjacent versions.
In some embodiments, the location change information may be obtained via a process 300 as shown in FIG. 3.
Specifically, in step 310, the contents of each file included in any at least two adjacent versions are parsed to obtain the elements to be displayed in any at least two adjacent versions respectively.
Here, the file content may include, for example, the content of each chapter of the electronic book, and the element to be displayed may be understood as any content that may be presented on a screen (e.g., the screen of the terminal device shown in fig. 1) in the electronic book, such as text, pictures, audio, video, graphics, and forms (e.g., control elements) that may be operated by a user in the electronic book.
In some alternative implementations, the adjacent two versions of the element to be displayed may be separately saved in a list manner.
In step 320, the Longest Common Substring (LCS) of the elements to be displayed having the same file name in any at least two adjacent versions is obtained. Here, LCS is understood to be the longest identical part of the adjacent two versions. In some optional implementations, the sections of each version may be stored in different lists, and in these optional implementations, LCS of each section in two adjacent versions may be obtained respectively.
In step 330, based on the longest common substring, the mapping relationship of the to-be-displayed elements with the same file name in any at least two adjacent versions is obtained as position change information.
Here, the same file name may be used to characterize the same chapter in any at least two adjacent versions of an electronic book, for example.
In some optional implementations, the updating the current version of the user annotation data based on the location update file in step 240, and obtaining the user annotation data corresponding to the version to be updated may further include: acquiring user marking data of a current version; analyzing the position information of each user label in the user label data of the current version; and updating the position information of each user label in the user label data of the current version based on the position updating file.
