Example Embodiment

[0032] With reference to the accompanying drawings, the present invention is further described:

[0033] A method for generating in-page navigation oriented to the accessibility of webpage content, the method includes the following steps:

[0034] 1. After scraping web pages from the Internet, do the following for each web page:

[0035] 1) Use the data item extraction algorithm to extract the data items of the web page, that is, the data presented in the web page through a consistent structure.

[0036] 2) Use the page block division algorithm to divide the page into blocks, and the parallel data items are divided into the same block during block division;

[0037] 3) A two-level navigation index tree is established by using data items and divided blocks. The first level is the blocks of the web page, and the second level is the data entries in each block.

[0038] 2. The data entry extraction algorithm described in step 1) is as follows:

[0039] 1) Establish the HTML tag...

Abstract

The invention discloses an in-page navigation generation method facing barrier-free access to webpage contents. After webpages are captured from an Internet, aiming at each webpage, the method comprises the following steps of: resolving the webpage into a document object model (DOM) tree structure through a hyper text mark-up language (HTML) resolver, and performing data item extraction on the webpage according to an editing distance between DOM trees; initially dividing the webpage according to some rules, detecting a separator between initially divided blocks, calculating the inconsistency degree of the inner parts of the blocks according to the maximum separator, and performing actual block division on the webpage according to the inconsistency degree of the inner parts of the blocks; and finally arranging the blocks of the webpage and the data items to form a two-level in-page navigation. The method has the advantages that the two-level in-page navigation is supplied to the webpage; a user, particularly a user who suffers from vision disability and accesses the webpage contents through screen reading software, can quickly learn about the contents of respective parts of the webpage so as to quickly lock the contents in which the user is interested; and the surfing experience of the user is enhanced.

Description

technical field [0001] The invention relates to the technical field of in-page navigation generation of barrier-free web pages, in particular to an in-page navigation generation method based on web page data item extraction and web page segmentation. Background technique [0002] According to the results of the second national sample survey of disabled people in 2006, there are 12.33 million people with visual disabilities in my country, and they are a group with special difficulties in society. With the high popularity of the Internet and the increasing importance of the Internet in daily life, the problem of webpage information accessibility for the visually disabled has become an important content of my country's information accessibility construction. Due to physical impairment, the visually impaired cannot normally read the content on the webpage, so the problem of surfing the Internet is particularly prominent. [0003] Visually impaired people often use screen reader...
