Abstract: A neural intelligent mail query agent. The neural intelligent mail query agent includes an online analytical processing system for accessing and analyzing data in at least one database, a query-by-mail system coupled to the online analytical processing system for receiving and processing queries from users for information derived from databases, and a neural network coupled to the remote query-by-mail system for providing learning capabilities in response to the remote mail queries. An expert system provides inference functions and the neural network is trained using a data stream from the databases as it is generated by the received mail queries. The neural network reports intelligence abstracts to the query-by-mail system as well as reports and organizes new rules constructed from the intelligence abstracts and existing rules.
