24. Conclusions Do not submit a paper too fast ! –Reflection not only on the contents, but also on the titles needed Mining Text/Web/Semi-structured Data are very popular now. Statistics and Probability is a very stronger topic. Security and Privacy Issues become stronger. Visualization/Interaction are emerging in ICDM 2003: –Visualization/Human-Machine Interaction –Postprocessing of DM Results –Process-centric DM
