<p>The DeepSpot Agent Toolbox exploits online Web data sources using reconfigurable Web wrapper agents. These agents are rapidly generated and executed on the basis of the XML-based Web Navigation Description Language and extraction rule generator IEPAD (information extraction based on pattern discovery). A WNDL script describes how to locate, extract, and combine data. By executing different WNDL scripts, users can automate all types of Web browsing sessions. They also describe IEPAD, a data extractor based on pattern discovery techniques. IEPAD lets software agents automatically discover the extraction rules to extract the contents of a structurally formatted Web page without the need to label a Web page to train a wrapper. With this programming-by-example authoring tool, users can generate a complete Web wrapper agent by browsing the target Web sites. Various applications demonstrate this approach's feasibility.</p>
