Our mission

is to

advance cutting
-
edge research and
applications of

knowledge technologies
that
suppor
t

the

analysis,
modeling and
management

of knowledge and
data
.


We have authored and edited numerous scientific books
and coordinated several EU projects.


Our technologies have been successfully applied to many
practical problems.


We are active in education and transfer of knowledge, and
act as a bridge between science and industry in Slovenia
and abroad.
