Abstract: A method for effecting transactions across multiple vendors in an integrated environment, wherein the user may purchase each of a plurality of items the user finds independent of the vendors. The user's selections are received from the user and mapped to selected set of vendors. When the user is finished, she invokes a check-out application to fill in one or many order entry forms for each of the relevant vendors whose goods the user selected during the course of shopping. The check-out application uses common information, such as name, address and credit card number, previously provided by the user in order to fill in the order entry forms for each vendor without requiring the user to fill in these forms. Finally, the check-out application tracks confirmation numbers in a common information store.

Abstract: A method of automatically filling in on-line forms presented by web pages in an internet transactional environment by determining based upon selectable criteria a form identifier corresponding to a particular on-line form, and thereupon, for each form so identified, identifying one or many corresponding match patterns with which a page containing a target on-line form is parsed to obtain a plurality of attributes, and thereupon, for each attribute obtained in the parsing step, indexing into a database to obtain and then appropriately transform user information which may be used to fill in the target form.

Abstract: A method is provided for determining how semistructured information is organized in disparate semistructured resources by providing a wrapper to extract information and to provide structured information (e.g., tuples of an SQL database) to a mapper coupled to a standard relational database engine. In a specific embodiment, a querying agent is provided on top of the mapper. Further according to the invention, structured high-level user queries are processed across the disparate semistructured resources using a plurality of wrappers each dedicated to a particular resource.
