Only model names, merchandise names, and substances are Employed in the current analysis. Retrieval was performed quickly using a robotic scraper in compliance Using the retailer’s phrases of use and robotic exclusion protocol (). The scraping application was penned in Java and utilized the XPath extensions to traverse the retailer’s revealed web-site map, as well as Apache HttpClient (Edition three.1; Apache Software Basis) to ask for item Web content. (On the other hand, users need to be knowledgeable that HttpClient is no more supported.
