When an author submits a paper, they will be asked to select one primary subject area, and up to 10 secondary subject areas from the sets of terms below. The terms have been grouped to provide a somewhat systematic overview of topics relevant to the KDD conference. For example, a paper about information extraction from Web pages using latent variables could select the combination primary = text, secondary = [hidden/latent variables, Web and ecommerce]; a paper about outlier detection in protein sequences could select primary = outlier and anomaly detection, secondary = [bioinformatics, sequences]; a paper about theoretical results related to the complexity of "learning to rank" problems could select primary = ranking, secondary = complexity analysis; and so on.

For reference the list of subject areas that will appear to authors and reviewers in the CMT conference management system:
