Upon the retirement of an area editor, Hendrik Blockeel, we are happy to introduce two new area editors, Kouzo Ohara and Fujio Toriumi. Ohara succeeds Blockeel and continues to handle the major field Data Mining, though the topics of the field slightly change due to the expertise of Ohara. We have decided to set up the new area Computational Social Science, whose area editor is Toriumi. The description of these two major fields follows this introduction. We sincerely hope that these two research areas will make the journal further contribute to new computing paradigms and computational intelligence.
