Data mining is the science of finding unexpected, valuable, or interesting structures in large data sets. It is an interdisciplinary activity, taking ideas and methods from statistics, machine learning, database technology, and other areas. It poses novel challenges, in part arising from the sheer size of modern data sets. Although there is no doubt that it addresses important questions, there are deep issues to be resolved relating to data quality and the nature of inference. Statisticians have an important role to play in resolving these issues.
