Abstract

A network-based intelligent information-sourcing system has capabilities akin to an automated universal teacher, researcher, or expert, in that the system is able to interpret, both independently and in context, and provide comprehensive answers to received queries on substantially any subject. This capability is achieved by enhancing existing telecommunications networks and intelligent networks to incorporate a knowledge-processing capability. This network uses the communication capability of the network to collect queries from, e.g., students in an interactive mode, then passes the question to a "knowledge ring" which comprises numerous knowledge bases arranged hierarchically, and then sends the response back from an "artificially intelligent instructor". Once the query is understood, the system restates the question back to the student in the way the particular knowledge base is integrated, Upon confirmation, the system delivers the response back to the student.
