Computer systems and methods for connecting buyers and sellers of products or services

摘要

The present invention relates to a computer-implemented system for connecting a buyer (1) and a seller (2) of a product or service (36) comprising a data storage site (11) which is a knowledge base comprising product or service definitions (36) offered for sale or purchase and associated structured data including classification criteria. The computer-implemented system further includes an internet access through which a potential buyer (1) can make a request for a product or service (36) that he / she wants to purchase and through which a seller (2) may make offers for a product or service (36) that he wishes to sell. The computer-implemented system includes a multi-part analysis engine including a classification engine for transforming a request made in natural language into a set of structured criteria corresponding to structured data in said data archiving site (11).
