Grant Description

Summary and Description of the grant

We have a richness of data about numerous aspects of our activities, yet these
data are only any use when we know what they are, agree upon what they are and
how they relate to each other. Semantic descriptions of data, the means by
which we can achieve these aims, are widely used to help exploit data in
industry, academia and at home. One way of providing such meaning or semantics
for data is through "ontologies", yet these ontologies can be hard to build,
especially for the very people that are expert in the fields whose knowledge
is being captured but who are not experienced in the specialised "modelling" field.

In the "what if...?" project we look at
the problems of creating ontologies using the Web
Ontology Language (OWL). With OWL logical forms, computers can
deduce knowledge that is only
implied within the statements made by the modeller. So any statement made
by a modeller can have a dramatic effect on what is implied.
These implications can be both "good" and "bad" in terms of the aims of the
modeller. Consequently, a
modeller is always asking themself "what if...?" questions as they model a field
of interest. Such a question might be "what happens if I say that a planet
must be orbiting a star?" or "what happens if I add in this date/time
ontology?".

The aim of the "what if...?" project is to
build a dialogue system allowing a person building an ontology
to ask such questions and get
meaningful answers. This requires getting the computer to determine what
the consequences of a change in the ontology would be and getting it to
present these consequences in a meaningful way. To do a good job,
the system will have to understand something about what the person is trying
to do and what sorts of results will be most interesting to them. For this,
we need to understand more about
how ontologists model a domain and interact with tools; be able to model the
dialogues between a human and the authoring system; achieve responsive
auttomated reasoning that can provide the dialogue system with the information
it nees to create that dialogue.
