VOX : an extensible natural language processor

VOX is a Natural Language Processor whose knowledge can be extended by interaction with a user.VOX consists of a text analyzer and an extensibility system that share a knowledge base. The extensibility system lets the user add vocabulary, concepts, phrases, events, and scenarios to the knowledge base. The analyzer uses information obtained in this way to understand previously unhandled text.The underlying knowledge representation of VOX, called Conceptual Grammar, has been developed to meet the severe requirements of extensibility. Conceptual Grammar uniformly represents syntactic and semantic information, and permits modular addition of knowledge

Nomad, a naval message understanding system

We are building systems to automatically analyze Navy messages. Such messages typically are terse and use many abbreviations and Navy jargon. As a result, they are more difficult to understand than everyday English.The NOMAD system interacts with a message sender to ensure that only unambiguous and reasonably correct messages are generated. The VOX system will allow a human tutor to interactively extend the knowledge base of NOMAD
