MLG 2007 is a followup to the successful series of conference workshops called Mining and Learning with Graphs (MLG), and Mining Graphs, Trees and Sequences (MGTS) organized within ECML-PKDD during the past four years. Because of the growing interest of machine learning and data mining researchers in the area of structured data (sequences, trees, graphs), MLG 2007 is organized as an independent event. Below is a list of past editions.
