complaints of the citizens can be expressed. Further,
they assumed that by using answer set semantics and
DLV-HEX as a solver, they can generate more expre-
sive rules than using Semantic Web Rule Language
(SWRL) (SWRL, 2004). They applied constraints on
the complaints to rank them based on their impor-
tance. For our case, this approach can also be investi-
gated and applied.
6 CONCLUSIONS AND FUTURE
WORK
We have presented an approach for integrating rele-
vant parts of context in user interaction process us-
ing semantic web technologies, Answer Set Program-
ming and DLV-HEX as a solver. This approach al-
lowed us by the use of constraints to limit and to pri-
oritize the set of fired facts. We have achieved thereby
an efficient problem reduction, since this approach
scales the size of the answer sets and the run time.
We plan to enable the user interface characteristics to
change dynamically, according to dynamic change of
user characteristics and situations that are detected at
run-time from the Context Ontology. The combina-
tion of concepts from other ontologies such as User
Profile Ontology (UPO) and the Context Ontology are
possible. Furthermore, we plan to automatically de-
tect the user’s intention.
