KDD 2017 is the 23rd SIGKDD Conference on Knowledge Discovery and Data Mining, one of the world’s largest and best Data Science conferences. Started in 1989, KDD is the oldest & largest data mining conference worldwide. We pioneered “Big Data”, “Data Science”, and “Predictive Analytics” solutions before these names even existed – some of the first & most highly cited research papers on these topics were published in our conference. Other notable innovations that originated in our conference include crowd sourcing; large scale data mining competitions with over 10,000 participants, personalized advertising, e.g., on Google, graph mining algorithms that power Facebook & LinkedIn, and recommender systems used by Netflix, Amazon, etc. After 25 years and an explosive growth in this industry, we are still the home for the latest cutting-edge research in these topics. Even today, the technology & research discussed at our conference is often 1-3 years ahead of any other conference!
