Abstract:
1. A non-transitory computer-readable medium embodying a program executable in at least one computing device, the program comprising: code that obtains, from a data store, a first album representing a first sequence of captures corresponding to a first subset of a plurality of web pages from an electronic commerce system, wherein individual ones of the first sequence of captures comprise a respective image of a respective rendering of a respective one of the web pages in a browser, a respective document object model (DOM) tree of the rendering, and a plurality of attributes of the respective one of the web pages; code that obtains, from the data store, a second album representing a second sequence of captures of a second subset of the plurality of web pages from the electronic commerce system; code that identifies a plurality of correlated pairs between the first album and the second album, wherein the plurality of correlated pairs are identified as having a positive degree of correlation between the attributes of a respective first capture from the first album and a respective second capture from the second album; code that generates a differential for individual ones of the correlated pairs comprising a plurality of locations at which one of a plurality of pixels differs between a respective first image of the respective first capture and a respective second image of the respective second capture in a respective correlated pair and a measure of a difference in dimensions between a respective first DOM tree of the respective first capture and a respective second DOM tree of the respective second capture in the respective correlated pair; and code that generates a notice associated with the correlated pairs in response to at least one of the differentials meeting a predefined threshold.
