I-ViDE: An Improved Vision-Based Approach for Deep Web Data Extraction

Provided by: Iosrjournals
Topic: Big Data
Format: PDF
Deep Web contents are accessed by queries submitted to Web databases and the returned data records are enwrapped in dynamically generated Web pages (they will be called deep Web pages in this paper). Extracting structured data from deep Web pages is a challenging problem due to the underlying intricate structures of such pages. Until now, a large number of techniques have been proposed to address this problem, but all of them have inherent limitations because they are HTML language dependent. Visual features are not taken into consideration.
