Proceedings of the 24th ACM International on Conference on Information and Knowledge Management

Warm welcome to the 2016 ACM International Conference on Information and Knowledge Management (CIKM 2016)! CIKM is held annually at locations all over the world. The last two years it has been in Australia and China. In 2016 it returns to the United States in Indianapolis and is held Oct. 24-28. CIKM 2016 will be the 25th running of the conference, which remains the only conference that inherently focuses on the need for users to have unified systems that access structured and unstructured data. With a new theme on Frontier and Applications of Big Data Science, CIKM 2016 further broadens the scope of topics of CIKM to include all topics in the general area of data science, including both foundational work and applications and encouraging interdisciplinary topics across multiple relevant communities such as information retrieval, databases, data mining, and knowledge management. CIKM has traditionally emphasized on relevance to industry and government applications; CIKM 2016 continues this tradition and further increases this emphasis by including a CIKM Cup Workshop and expanding its Industry Track to include a variety of submissions including long papers, short papers, and software system demonstrations in addition to its invited talks. Furthermore, to facilitate recruiting and encourage interactions between students and industry recruiters, CIKM 2016 introduced a new Career Day event. The conference also has a special session \"CIKM at its 25th Anniversary\" to celebrate its growth and success. The whole conference program includes eight tutorials, eight workshops, 182 oral presentations of full papers, 116 poster presentations of short papers, 20 system demonstrations, and three keynote talks. We are honored and grateful to have three outstanding members of National Academy of Engineering as our keynote speakers, Rakesh Agrawal, Andrei Broder, and Susan Dumais.
