Web page annotation system and method

Abstract

The invention relates to a webpage annotating structure, a webpage annotating system and a method thereof. A webpage browser opens a webpage as a bottom webpage which is covered with a layer of XML vector graph webpage annotation, wherein the annotation comprises an annotation layer established by a user; moreover, each user can establish a self annotation layer on the same webpage to make a multilayer vector graph annotation layer covered on the same bottom webpage; the user can edit various annotation objects on the bottom webpage and can put the annotation objects in the self annotation layer; and all annotation objects are XML vector graph elements and have excellent maneuverability. When the user wants to share the webpage annotation with another user, he or she just needs to transmit the website of the bottom webpage and the self annotation layer to the object user. When the user changes an annotation layer, other users just need to replace the changed annotation layer without copying an entire file, thereby reaching the goal of common edit by means of a more efficient difference update mode.

Description

technical field [0001] The present invention relates to a webpage annotation system and method, in particular to a webpage annotation system and method using XML-based vector graphic technology, wherein XML is an extensible markup language (eXtensible Markup Language) Abbreviation for . Background technique [0002] In the age of the Internet, web pages are one of the main sources of information for modern people. At present, there are billions of webpages in the world providing people with various types of information services, and the number of webpages is still growing rapidly. When people browse the web, they sometimes need to add their own opinions, labels, or annotations (annotations) on the content provided by the webpage, such as adding their own opinions to the news, drawing labels on the stock price trend chart , Or write down your own experience on the teaching webpage. In this case, people usually print out the webpage and add these annotations on the printed ...

AI Technical Summary

Problems solved by technology

First, web pages are converted into bitmap files that occupy a considerable space, requiring more storage and bandwidth resources for storage and transmission

Second, the annotations made on the web page bitmap files are themselves bitmaps, which lack manipulability, such as moving, copying, rotating, hiding, zooming, changing the color and transparency of individual annotations, etc.

Third, sharing the bitmap file of webpage annotations is to copy and send the entire file to each user, and each user has his own copy file, so the subsequent annotations made by any user cannot be updated to other users. Duplicate archives from the same source

In other words, sharing groups cannot co-edit the same page annotation

Fourth, when a webpage annotation bitmap file is annotated by multiple people, the content will appear disorderly, and users cannot selectively delete or hide some unnecessary annotations

Fifth, although some software such as CorelDraw or Adobe's Illustrator can be used to convert the web page into a vector graphics file supported by it, and then annotate it with the annotation tool that supports vector graphics editing, but these software are all For window-based applications, it does not support differential updates and co-editing, and cannot be directly displayed in a web browser

The disadvantage of this kind of annotation on web pages in HTML format is the lack of graphical annotation functions such as handwriting or highlighter

In addition, this kind of annotation in HTML format lacks a multi-level structure, and it is impossible for each user to have different levels of annotation on the same web page, so it cannot support sharing, differential update and joint editing
