Cognition holds the key to the holy grail of human-computer interaction - natural language and intelligent dialogue, technology that will transform how we interface with machines. Decades of research by the company's founders in the fields of computational linguistics and semantics have led to a system that understands what users actually mean and is able to follow the thread of a conversation, dynamically adapting to the direction of the dialogue.Cognition was acquired by Nuance Communications in June 2013.
