dicators to be evaluated for a given set of impacting
actions.
The knowledge base of IASEIA has been devel-
oped by relying on the CDS pattern, an ontology de-
sign pattern to create ontologies that allows the char-
acterization of the significant domain information of
a given context. The CDS pattern promotes modu-
larity and reusing of the knowledge models. Thus, it
is possible to enhance the models by adding or cre-
ating more specific ontologies covering more detailed
aspects of the EIA process. The context and the do-
main ontologies can be easily extended with addi-
tional knowledge to describe additional actions and
indicators. Building a comprehensive actions ontol-
ogy is a difficult task, and therefore it may be neces-
sary to incorporate new terms to describe actions that
were not predicted in the development of the context
ontology. Similarly, indicators may change if differ-
ent assessment methodologies are used.
Actually, our ongoing and future work is focused
on the enhancement of the knowledge models under
the supervision of environmental experts. The devel-
opment of more accurate models will serve as a basis
for the future real use of the system, both in indoors
and outdoors scenarios.
