Technique to allow AI to learn words in the flow of dialogue developed [osaka-u.ac.jp]

A group of researchers at Osaka University has developed a new method for dialogue systems. This new method, lexical acquisition through implicit confirmation, is a method for a computer to acquire the category of an unknown word over multiple dialogues by confirming whether or not its predictions are correct in the flow of conversation.

[...] The group led by Professor Komatani developed an implicit confirmation method by which the computer acquires the category of an unknown word during conversation with humans. This method aims for the system to predict the category of an unknown word from user input during conversation, to make implicit confirmation requests to the user, and to have the user respond to these requests. In this way, the system acquires knowledge about words during dialogues.

In this method, the system decides whether the prediction is correct or not by using the user response following each request, its context, by using machine learning techniques. In addition, this system's decision performance improved by taking the classification results gained from dialogues with other users into consideration.
