Recent trends in website design have an impact on methods used for web data extraction. Many existing methods rely on structural analysis of web pages and, with the introduction of CSS, table-based layouts are no longer used, while responsive design means that layout and presentation are dependent on browsing context which also makes the use of visual clues more complex. We present DeepDesign, ...

Record extraction from data-rich, unstructured, multiplerecord Web documents works well [9], but only if the text for each record can be located and isolated. Although some multiple-record Web documents present records as contiguous, delineated chunks of text (which can thus be located and isolated [10]), many do not. When some values of textual records are factored out, are split unnaturally a...

The design of web information extraction systems becomes more complex and time-consuming. Detection of data region is a significant problem for information extraction from the web page. In this paper, an approach to vision-based deep web data extraction is proposed for web document clustering. The proposed approach comprises of two phases: 1) Vision-based web data extraction, and 2) web documen...
