This webpage contains papers, conference presentations and
supplementary material relating to our research on representing
the meaning underlying stories by directed acyclic graphs.

The earliest of the papers, the first below, gives an overview
of our basic premise. We have subsequently considered a wide range
of the features which occur in narratives: the representation of
space, semantic repetition, time, ethics and behavioural issues,
and so on. Papers relating to these topics may be found in the
other papers and the section on supplementary material.

A much expanded version of the Istanbul paper, containing a more
comprehensive discussion of the premise has been completed, and will be
posted here in due course.

The slide sets below include incremental sequences. On browsers
which use Adobe Acrobat the arrow keys should cause them to build
incrementally.
