The Wrapper Induction Environment

Nick Kushmerick and Brett Grace

There is much interest in systems that automatically interact with Internet information sites. Such systems are hard to build, partly because they use hand-crafted wrappers to extract a site’s content. We advocate wrapper induction, a technique for automatically learning wrappers. Our Wrapper Induction ENvironment (WIEN) enables users to quickly capture a set of example page; our wrapper learning algorithm then handles the low-level details of constructing the wrapper.
