Web application slicing

Abstract

Program slicing revealed a useful way to limit the search of software defects during debugging and to better understand the decomposition of the application into computations. We propose to extend the extraction of slices to Web applications, in order to produce a reduced Web application which behaves as the original one with respect to some criterion, i.e., some displayed information of interest. After presenting the theoretical implications of applying slicing to Web applications, we demonstrate its usefulness with reference to an example, derived from a survey of a set of travel agency sites. Web application slicing helps to disclose relevant information and understand the internal system structure.
