Abstract: An artificially intelligent system comprising a plurality of autonomous virtual machines, anonymously matching advertisements over a publicly accessible electronic network. The system automates matching of free form electronic documents for supply and demand of goods or services. Each machine employs an expert system with a geographical bias, an inherent learning capability, and tendency to improve accuracy over time. Advertisements and knowledge bases are replicated to identically configured networked machines. Each machine elicits a qualified, interactive response to an advertisement, employing electronic commerce in the purchase of contact information for a supplier, by a demander.
