First of all, we appreciate the hard work of all the authors who contributed to ICEC 2005 by submitting their papers. ICEC 2005 attracted 95 technical paper submissions, 8 poster submissions and 7 demo submissions, in total 110. This number is nearly equal to ICEC 2004. Based on a thorough review and selection process carried out by 76 international experts from academia and industry as members of the senior and international program committees, a high-quality program was compiled. The program committee consisted of experts from all over the world: 1 from Austria, 3 from Bulgaria, 2 from Canada, 4 from China, 1 from Finland, 4 from France, 10 from Germany, 1 from Greece, 1 from Ireland, 1 from Israel, 1 from Italy, 26 from Japan, 1 from Korea, 4 from The Netherlands, 1 from New Zealand, 1 from Norway, 1 from Singapore, 1 from Thailand, 4 from the UK, and 8 from the USA. In this number, reviewers are included. The final decision was made at the senior program committee meeting based on three reviewers' feedback, available online via the conference management tool. Through earnest and fair discussion at the meeting, 25 technical papers were accepted as long papers and 32 technical papers were accepted as short papers from 95 submitted technical papers. Moreover, 3 poster papers and 5 demo papers were accepted.
