Abstract: An Internet portal allows potential buyers to locate and to communicate directly with suppliers of various goods or services. Potential buyers can conduct a search for suppliers through the Internet portal. The potential buyer then selects from a list of suppliers that have been identified through one or more searches. The buyer can link directly to the website of the selected suppliers. The buyer can then select one or more products displayed on the supplier's web site. Unstructured information relating to the selected products is then converted to structured information and stored in a database. The buyer can transmit requests for information, requests for quotes, and purchase orders directly to suppliers through the Internet portal. Buyers and suppliers can collaborate and negotiate with each other through the Internet portal to reach a final acceptable state for a transaction.
