document: DOM-based content extraction of HTML documents Web pages often contain clutter ( such as pop-up ads , unnecessary images and extraneous links ) around the body of an article that distracts a user from actual content . Extraction of `` useful and relevant '' content from web pages has many applications , including cell phone and PDA browsing , speech rendering for the visually impaired , and text summarization . Most approaches to removing clutter or making content more readable involve changing font size or removing HTML and data components such as images , which takes away from a webpage 's inherent look and feel . Unlike `` Content Reformatting '' , which aims to reproduce the entire webpage in a more convenient form , our solution directly addresses `` Content Extraction '' . We have developed a framework that employs easily extensible set of techniques that incorporate advantages of previous work on content extraction . Our key insight is to work with the DOM trees , rather than with raw HTML markup . We have implemented our approach in a publicly available Web proxy to extract content from HTML web pages .
