摘要：
An increasing amount of Web data is accessible only by filling out HTML forms to query an underlying data source. While this is most welcome from a user perspective (queries are easy and precise) and from a data management perspective (static pages need not be maintained; databases can be accessed directly), automated agents have greater difficulty accessing data behind forms. In this paper we present a method for automatically filling in forms to retrieve the associated dynamically generated pages. Using our approach automated agents can begin to systematically access portions of the "hidden Web."
