Current WYSIWYM applications
We have applied WYSIWYM to a number of systems being developed
at the ITRI. Here is a sample list:
- Drafter-II: Origins
- WYSIWYM developed from the GIST and DRAFTER projects which
were in progress during 1993-96. The first WYSIWYM system was
a re-implementation of DRAFTER by Richard Power in 1996, which
generates software instructions in English, French and Italian.
-
- Drafter-III: Coreference
- A serious limitation of Drafter-II was the lack of any control
over coreference. The knowledge author could not specify that
two phrases in the feedback text referred to two different tokens
of the same type, rather than to the same token. In 1998 Kees
van Deemter and Richard Power designed a further version of DRAFTER
in which the editing operations were extended to allow control
over coreference.
-
- Iconoclast: Logical scope
- To meet the requirements of the Iconoclast project, in which
we generate Patient Information Leaflets (which include much
logically complex material such as conditionals), the editing
operations in WYSIWYM were extended further to allow some control
over logical scope. During 1998-99 Richard Power, with help from
Rodger Kibble and Kees van Deemter, developed a demonstration
system in which the editing choices made by the author lead to
the construction of a Discourse Representation Structure, entities
being assigned logical scopes by binding them to DRT boxes.
-
- CLIME: Query definition
- Complex queries to a database or an expert system usually
have to be expressed in a special formalism. In the CLIME system,
which answers questions about maritime law, a WYSIWYM interface
allows users to define their queries through a feedback text,
either in English or Italian. The system has been developed during
1998-99 by Paul Piwek.
-
- CLIME: Plurals
- In the latest version of the CLIME query interface, Paul
Piwek has added new WYSIWYM editing operations which allow the
user to construct plural entities (e.g. the pumps) and
to define relations between individual entities and collections
(one of the pumps) or between collections and sub-collections
(some of the pumps). These operations are related to a
DRT treatment of plurals.
-
- PILLS: Patient Information Leaflets
- A web-based application was developed in 1997 to illustrate
the potential of WYSIWYM as the basis for a system that could
generate patient information leaflets in many languages and styles.
In addition to the Drafter-II languages the PILLS system generates
output in German, Dutch and Portuguese. Intended as a demonstration
of the concept rather than a full NLG system, PILLS does not
allow authors to control the meaning of the output texts in detail;
most choices result in the creation of a prefabricated proposition
rather than an individual entity.
