“This year CIKM Cup presents two realistic industry problems and serves as an excellent opportunity for learning about data science and exploring novel ideas highly relevant to CIKM including, data mining, information retrieval, machine learning, and NLP, among others.”

“To be a successful (data) scientist in the modern era, researchers and practitioners alike need to engage in both research and practice on realworld problems. The CIKM Cup 2016 provides two real-world competitions. Consider preparing a submission (and win some money)!”
