In this paper, we presented a tool to exploit online Web data sources using reconfigurable Web wrapper agents. We described how these agents can be rapidly generated and executed based on the script language WNDL and extraction rule generator IEPAD. WNDL is an XML-based language that provides a representation of a Web browsing session. A WNDL script describes how to locate the data, extract the...

To decouple test code from web page details, web testers adopt the Page Object design pattern. Page objects are facade classes abstracting the internals of web pages (e.g., form fields) into high-level business functions that can be invoked by test cases (e.g., user authentication). However, writing such page objects requires substantial effort, which is paid off only later, during software evo...

The presence of replicas or near-replicas of documents is very common on the Web. Whilst replication can improve information accessibility for the users, the presence of near-replicas can hinder the effectiveness of search engines. We propose a method to detect similar pages, in particular replicas and near-replicas, which is based on a pair of signatures. The first signature is obtained by a r...
