Longitudinal study of website structure

This is an instance of the LabPal experimental environment that processes data files about the structure of web sites. The lab contains results of a large-scale survey of websites, in order to measure various features related to their size and structure: DOM tree size, maximum degree, depth, diversity of element types and CSS classes, among others. The goal of this research is to serve as a reference point for studies that include an empirical evaluation on samples of web pages.
