The 21st ACM International Conference on Information and Knowledge Management (CIKM 2012) will be held from October 29 to November 2, 2012 in Maui, USA. CIKM is a well-known top tier and premier ACM conference in the areas of information retrieval, knowledge management and database. 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 2012, we will continue the tradition of promoting collaboration among multiple areas. We encourage submissions of high quality papers on all topics in the general areas of databases, information retrieval, and knowledge management. Papers that bridge across these areas are of special interest and will be considered for a "Best Interdisciplinary Paper" award. Topics of interest in the three tracks include, but are not limited to:

Databases:
Access methods and indexing
Authorization, data privacy and security
Concurrency control and recovery
Data adaptability, reusability and quality
Database languages and models
Information integration, data provenance, probabilistic databases
Mobile databases and distributed data management
Peer-to-peer, parallel and distributed databases
Query processing, optimization and performance
Real-time and active databases
Scientific and biological databases
Semantic Web
Semi-structured data processing, XML filtering and routing
Stream-based processing and network databases
String databases, blogs and social search
Systems, middleware, applications and experiences
Temporal, spatial and multimedia databases
User experience: languages, models, interfaces

Information Retrieval:
Citation Analysis, Social Networks for IR
Distributed IR, Peer to Peer Search
Domain-specific IR (e.g., Legal IR, Genome, Mobile IR, IR for chemical structures)
Filtering (e.g., Routing, Collaborative filtering, Topic tracking, Recommender systems)
Foundation of Information Retrieval (e.g., theory, ranking)
IR Architectures, Scalability and Efficiency
IR Evaluation
Language Specific IR (Multi-lingual, Cross-lingual, NLP, Question and Answer)
Machine Learning for IR
Multimedia IR (Audio, Speech, Video, Image)
Semi-Structured Information Retrieval
Distributed IR, Peer to Peer Search
User Modeling for IR, Search Personalization
User Studies, Interactive Information Retrieval, Interfaces and PIM
Web Search, Advertising, Adversarial
Other topics related to IR (Privacy, Spam, Feature Engineering, et. al.)

Paper Submissions for CIKM 2012
Authors are invited to submit original, unpublished research papers that are not being considered for publication in any other forum. Manuscripts should be submitted electronically, in PDF format and formatted using the ACM camera-ready templates available at: http://www.acm.org/sigs/publications/proceedings-templates
ACM CIKM review is double-blind. Therefore, please anonymize your submission. Papers cannot exceed 10 pages in length. There is no short paper track. The organizers may offer the authors of selected paper submissions to prepare a shorter version of their paper for presentation.

Note
Accepted workshop papers will also be published in the CIKM workshop proceedings, which will be printed on CD only and indexed in the ACM digital library, together with the main CIKM 2012 proceedings.
