The 24th ACM International Conference on Information and Knowledge Management (CIKM 2015) will be held from Oct 19-23, 2015 in Melbourne, Australia. CIKM is a top-tier ACM conference in the areas of information retrieval, knowledge management and databases. Since 1992, it has successfully brought together leading researchers and developers from the three communities, with the purpose of identifying challenging problems facing the development of advanced knowledge and information systems, and shaping future research directions through the publication of high quality, applied and theoretical research findings. With CIKM 2015, we will continue the tradition of promoting collaboration among multiple areas and are arranging an exciting program for the conference, including workshops, tutorials, industry speakers, keynote speakers, research papers, and posters.
