Method and device for generating or displaying webpage label and information sharing system

Abstract

The invention discloses a method and a device for generating or displaying a webpage label and an information sharing system based on the webpage label. The method for generating webpage label information comprises the following steps: responding to a user to select a target webpage element on a current webpage loaded on a client Web browser as a labelled object and extracting an XPath path of the labelled object in a document object model (DOM) tree of the current webpage; based on the labelled object and contents of context webpage elements next to the front and back parts of the labelled object in the current webpage, generating a feature code CF of the labelled object; and based on the XPath path and the feature code CF of the labelled object and a label input by the user, generating the webpage label information, wherein the webpage label information is stored in a label database of a remote label server and the feature code CF of the labelled object consists of a content-based feature (CBF) of the labelled object and the CBFs of the context webpage elements of the labelled object.

Description

technical field [0001] The present invention generally relates to webpage tagging technology, and in particular to a technology for generating or displaying webpage tagging considering content of a target web page element on a web page as an tagged object, and a technology for realizing information sharing based on such web page tagging. Background technique [0002] Annotation is a technique for adding information to documents. This concept was originally produced in print media, including highlighting key words, adding marginalia, etc. With the rapid development and popularization of computer and network technology, the current network media has become one of the important ways for people to understand information. In this case, the technology of webpage annotation has also been paid attention to and developed, and webpage annotation has gradually become one of the hot topics in various fields including digital library, computer-aided collaborative work, information shari...

AI Technical Summary

Problems solved by technology

[0009] - Cannot handle the case where the annotated object is transferred to other pages

In many websites, specific elements in a page are often automatically listed in other pages as the content scrolls, and traditional webpage labeling methods cannot display such labels;

[0010] -When the format of the tagged object in the web page undergoes certain tolerable changes (for example, the font in the tagged object becomes italic or blackened, etc.), the tag cannot be displayed correctly;

[0011] -In many cases, some modifications are often made to the content of the tagged object. In the traditional web tagging system, the tagged object whose content has been modified is considered to be no longer the original tagged content, so its tagging will no longer be displayed
