主要内容：Recent years have witnessed the revolutionary changes brought about by the development of multimedia technologies. These changes advance many disciplines and industries, and health is no exception. In such context, we observed: 1) With the help of crowd-based and social networking services, healthcare knowledge is more convenient to share, acquire and disseminate among health seekers and providers. This greatly facilitates the doctor-doctor, doctor-patient and patient-patient communication; 2) As compared to the traditional pure textual descriptions, health today is complementarily characterized by multi-modal data, such as images, audios and sometimes the videos. This enables doctors to concisely comprehend the health conditions of the patients; 3) Rather than embrace doctors’ orders, patients nowadays actively seek for online health information, and post their disease control experiences. At the same time, they are frequently overwhelmed by uneven health data in quality; and 4) Mobiles and other wearable health sensors are equipped by patients and doctors to track the health and exercises. This makes it possible for real-time monitoring and remote health support. The remarkable changes in health domain, at the same time, bring us many research opportunities in a broad spectrum of application domains, such as health data quality assessment, cross-source learning for better lifestyles, personalized health with sensor data, and health data visualization. In this talk, I will first elaborate the popular online health systems and health data collected from these systems, and then introduce the research efforts we have dedicated to the health domain in past three years. Following that, I will detail our latest work, i.e., progression modeling of chronic diseases. Finally, future potential research topics in health domain are discussed.
