The 23rd ACM International Conference on Information and Knowledge Management (CIKM 2014) will be held from Nov 3-7, 2014 in Shanghai, China. 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. The purpose of the conference is to identify challenging problems facing the development of future knowledge and information systems, and to shape future research directions through the publication of high quality, applied and theoretical research findings. In CIKM 2014, we will continue the tradition of promoting collaboration among multiple areas. We encourage submissions of high quality research papers and posters on all topics in the general areas of databases, information retrieval, and knowledge management.
