Call for Papers ACM Transactions on Intelligent Systems and Technology (ACM TIST) Special Issue on Intelligent Multimedia Systems and Technology Recent years witnessed the explosion of multimedia data on the Internet, desktop and mobile devices, and there has been an increasing demand of intelligent systems and technology to understand, index, manage, search and consume these data. Machine learning and data mining have proven to be promising approaches in many data-intensive applications, and many such efforts have also been dedicated to multimedia data. The objective of this special issue is to bring together latest research along this direction. We look for effective machine learning and data mining algorithms, frameworks, systems, and implementations that particularly work on multimedia data (including image, video, and audio, which may be also associated with textual information). The focus is to identify real challenges in intelligent multimedia systems and technology and to investigate practical solutions to the core problems of multimedia applications in both theoretical and practical perspectives. Topics of interest include but not limited to: (1) Intelligent systems for multimedia data management, index, search and sharing. (2) Machine learning technology for image, video and audio content understanding. (3) Machine learning technology for multimedia search. (4) Mining of multimedia data (image, video, audio, or any combination of them). (5) Social media analysis and mining. (6) Intelligent technology for Internet multimedia search. (7) Large-scale learning and mining algorithms for multimedia data. We will publish two issues on this topic, and the two issues have different submission deadlines.
