he European Conference on Machine Learning and Principles and Practice of Knowledge Discovery in Databases (ECML PKDD) took place in Athens, Greece from September 5th to 9th, 2011. This event builds upon a very successful series of 21 ECML and 14 PKDD conferences, which have been jointly organized for the past ten years.

It has become the major European scientific event in these fields and in 2011 it comprised presentations of contributed papers and invited speakers, a wide program of workshops and tutorials, a discovery challenge, a demo track and an industrial track.

The European Conference on Machine Learning and Principles and Practice of Knowledge Discovery in Databases (ECML PKDD 2011) took place in Athens, Greece, during September 5-9, 2011. This year we have completed the first decade since the junction between the European Conference on Machine Learning and the Principles and Practice of Knowledge Discovery in Data Bases conferences, which as independent conferences date back to 1986 and 1997, respectively. During this decade there has been an increasing integration of the two fields, as ref lected by the rising number of submissions of top-quality research results. In 2008 a single ECML PKDD Steering Committee was established, which gathered senior members of both communities
