NBi S started as a workshop and for 9 years it was held together with DEXA International Conference and is the oldest among DEXA Workshops. The wo- shop has been very successful in quantity and quality. We received many paper submissions every year, but as a workshop we could accept only a limited n- ber of papers. This was the?rst year that NBi S was run as an international conference together with DEXA. We received 122 research papers from all over the world. The submitted papers were carefully reviewed by at least two reviewers.
