Abstract
Description
Input: two Url of original list |
Output: the forward Longest Common Substring of representing the Data-rich district |
Algorithm steps: |
(1) input is based on the Url of two pages of same module. |
(2) respectively the HTML Tag of two pages tree is carried out degree of depth recurrence, if find to have the paging navigation nodes in its subtree, then its father node of mark is the start node of step (3), otherwise is start node with the root node of HTMLTag tree. |
(3) root node with mark in the step (2) begins, and HTML Tag tree is carried out degree of depth recurrence relatively, judges whether its subtree is consistent.If the path unanimity then is labeled as unanimity to this subpath, turn back to father node, continue to choose next single sub path relatively.If all subpaths of father node are all consistent, then the path of representative is the noise branch. |
(4) the forward Longest Common Substring of the different subtrees that will obtain output is as the tree path of Data-rich. |
The container class label | Modify the class label |
Table/tr/td/div/ul/li etc. | A/strong/font etc. |
