\section{List of Dialogues}
%==========================
\label{app:dialoglist}

\vspace{1em}

Below we give a table with information about each dialogue.  The order
of the list reflects the order in which the dialogs were collected.  The
first column gives the name of the dialog.  The second and third give
the codes for the user and system, which can be used to look up more
specific information about them in the table in
Appendix~\ref{app:speakers}.  The fourth column gives the problem
number, which can be used to access the problem descriptions in
Appendix~\ref{app:problems}.  The fifth column gives the length of the
dialogues in minutes and seconds.

The sixth column states whether a valid plan, which completes the
specified task within the specified constraints, was found: ``Y''
indicates one was found, ``N'' indicates that the proposed plan is not
valid, and ``G'' indicates that the system and user gave up and did
not complete a plan.  If the system miscalculated the time required
for the plan, but it does in fact meet the time constraints, then the
plan is marked as being valid.

The seventh column indicates the errors that the system or user made
that were not later resolved and that impacted the planning
process\footnote{Not all mistakes are viewed as errors.  Only the
following types of mistakes are included: those caused the time to be
computed wrong; those that forced the user to reject the current plan;
and those that caused the final proposed plan to be wrong.} The error
codes are explained in Appendix~\ref{app:errors}.  If the same type of
error was made more than once, its error code will be reported once
for each occurence.  Only errors that are part of the final plan were
included.  Errors that resulted in the initial plan being abandoned
are reported in the comments column.

Finally, the eighth column indicates any other comments.
