- E. Chang, Shih-Fu Chang, Alexander Hauptmann, Thomas S. Huang. 2012. Web-Scale Multimedia Processing and Applications. Abstract: This special issue provides a timely and comprehensive review of recent progress, applications, and challenges spurred by the introduction of web-scale data resources, involving text, image, video, speech, user recommendation, and their combinations. The first group of papers covers fundamental crosscutting techniques critical for developing web-scale systems, including large-scale linear classification, optimal hashing, robust graph-based semisupervised learning, and classifier adaptation. The second group reviews techniques for discovering knowledge, extracting information, and combining knowledge with multimedia content networks. The third group surveys representative work demonstrating the unique impact of web-scale data in practical applications, such as image annotation, media recommendation, enterprise social networks, and social media networks. This special issue is intended for broad audience interested in gaining comprehensive understanding of technical issues and opportunities in this important field. I . INTRODUCTION
