Mark Lee and a number of my students have created implementations of this approach and linked it to dialogue and other applications, but there has been no major application showing its essential role in a functioning conversational theory where complex belief states are created in real time.
like others, I came to see this assumption was quite untrue, and myself moved towards Machine learning (Ml) approaches to word-sense disambiguation (e.g., Stevenson and Wilks 2001) and I now work in Ml methods applied to dialogue corpora (as I shall mention subsequently).
