Abstract

A user of an information network is provided with information contained within at least one of plurality of network sites in view of a user search criteria by searching a database that is populated with a plurality of other search criteria provided by other network users and a plurality of search strategies. Each of the search strategies includes information regarding network sites likely to contain information relevant to the other search criteria. The other search criteria within the database are linked with the search strategies. At least one search strategy is selected from the database based upon the user'"'"'s search criteria. The search strategy is executed and the results are provided to the user in one embodiment, users can employ software agents to assist in searching, collecting, and reporting on data in accordance with the user'"'"'s specified criteria.

11. In an information network comprising a plurality of provider network sites, each having a provider associated therewith, and a plurality of requester network sites, each having a requester associated therewith, a method of introducing providers and requesters to each other based on a search criteria provided by at least one of said providers and requesters, said method comprising the steps of:

providing a database;

populating said database with network site data representative of the content of the network site from a plurality of said requester network sites and provider network sites, a plurality of other search criteria provided by other providers and requesters, and a plurality of search strategies comprising information regarding network sites likely to contain information relevant to said other search criteria;

linking at least one of said search strategies with at least one of said other search criteria;

on behalf of each requester providing requester search criteria, creating a requester search agent and employing said search agent to;

search said database for network site data and other search criteria relevant to said requester search criteria;

for each relevant other search criteria, executing said at least one search strategy linked with said other search criteria to search said information network for network sites having data relevant to said requester search criteria;

providing search results to said requester; and

on behalf of each provider providing provider search criteria, creating a provider search agent and employing said search agent to;

search said database for network site data and other search criteria relevant to said provider search criteria;

for each relevant other search criteria, executing said at least one search strategy linked with said other search criteria to search said information network for network sites having data relevant to said provider search criteria; and

providing search results to said provider.

12. The method of claim 11 wherein at least one of said providers and at least one of said requesters provides negotiation parameters in addition to said respective search criteria and said respective provider search agent and requester search agent are further employed to negotiate with other respective requester search agents and provider search agents in order to complete an introduction.

13. The method of claim 12 wherein said negotiation parameters includes at least one of a maximum offer price, starting offer price, counteroffer prices, time between counteroffers and negotiation time.

14. The method of claim 12 wherein at least one of said requesters provides consummation data in addition to said search criteria and said respective requester search agent is further employed to initiate and consummate a transaction with at least one provider search agents.
