System and method for distributed querying and presentation of information from heterogeneous data sources

摘要

A method, system, business method, and computer program product for retrieving and organizing networked data, wherein fetch rules and extraction rules enable a user to automatically collect and extract information from a remote network site. The fetch rules reproduce the interaction a client executes if interacting directly with the remote site, so a server cannot be shut out. The extraction rules allow the client, preferably via an applet, to glean relevant information from the acquired pages for presentation in a general interface. As an electronic commerce business method, information about remote site responsiveness, fetch rules, and extraction rules may be shared between server and client for a fee. The server accumulates vendor contacts, stores query rules, and provides common interface rules. The invention can gather statistics on vendor responsiveness and can resell information to vendors or others.
