CORPUS-BASED DIALOGUE SIMULATION FOR AUTOMATIC STRATEGY LEARNING AND EVALUATION

June 2001
This paper describes a method for simulating mixed initiative human-machine dialogues using data collected by a prototype dialogue system. The behaviour of the user population is modelled probabilistically using an explicit representation of user state. Recognition and understanding errors are also modelled. The simulation can be used for evaluation of competing strategies, as well as automatic learning of dialogue strategies.
If you have difficulty viewing files that end '.gz'
,
which are gzip compressed, then you may be able to find
tools to uncompress them at the gzip
web site.
If you have difficulty viewing files that are in PostScript, (ending
'.ps'
or '.ps.gz'
), then you may be able to
find tools to view them at
the gsview
web site.
We have attempted to provide automatically generated PDF copies of documents for which only PostScript versions have previously been available. These are clearly marked in the database - due to the nature of the automatic conversion process, they are likely to be badly aliased when viewed at default resolution on screen by acroread.
