Machine Processing of Dialogue States; Speculations on Conversational Entropy

Part of the Lecture Notes in Computer Science book series (LNAI,volume 9811)

Abstract

This keynote talk presents some ideas about ‘conversational’ speaking machines, illustrated with examples from the Herme dialogues. Herme was a small device that initiated conversations with passers-by in the Science Gallery at Trinity College in Dublin and managed to engage the majority in short conversations lasting approximately three minutes. No speech recognition was employed. Experience from that data collection and analyses of human-human conversational interactions has led us to consider a theory of Conversational Entropy wherein tight couplings become looser through time as topics decay and are refreshed by speaker changes and conversational restarts. Laughter is a particular cue to this decay mechanism and might prove to be sufficient information for machines to intrude into human conversations without causing offence.

Notes

  1. 1.

    There was a large screen behind Herme’s stand showing passers-by what she could see, with a coloured circle drawn around each face in the scene.

  2. 2.

    A Roland Sound Canvas.

  3. 3.

    Lectures delivered under the auspices of the Dublin Institute for Advanced Studies at Trinity College, Dublin, in February 1943.

  4. 4.

    The idea that household devices might be capable of eavesdropping on nearby conversations is rightly anathema to many kitchen owners and occupants.
