The emergence of microblog brings a fundamental change to traditional information diffusion patterns. While there are a significant amount of studies on modelling the information propagation in microblog networks, little prior work has considered sentiments of messages as factors or information entities for propagation studies. In this paper, we present our work on characterizing the impact of sentiments...
Nowadays, as social activities in the real world are getting more and more popular, it is important to understand the social interaction features and the social contexts of users (meetings, social gatherings, etc.) to support social activity organization. By leveraging the social context and activities of users, various services can be provided (e.g., recommendation of friends, activities, etc.)....
Internet is steaming with a great variety of information including instant news, music, advertisement, etc. However, users will be overwhelmed by too much information presented on web page at once. In this paper, we propose a context-aware mobile web browsing system to reduce user distraction and ultimately enhance user experience. First, we capture user context such as time and location information...
With the development of wireless communication, the popularity of smart phones, the increasing of social networking services, mobile social networking has become a hot research topic. The characteristics of mobile devices and requirements of services in social environments raise a challenge on building a platform for mobile social services. In this paper, we elaborate a flexible system architecture...
With the development of sensing, wireless communication, and Internet technologies, we are now living in a world that is filled with various smart things ¨C the Internet of Things. This paper introduces and prospects an emerging research area ¨C Embedded Intelligence (EI), which aims at revealing the individual behaviors, spatial contexts, as well as social patterns and urban dynamics by mining the...
Human memory is generally poor and often fails in unpredictable ways, sometimes with dire consequences. On social occasions, it usually causes embarrassing situations (e.g., forgetting the name of a friend). Moreover, as the number of contacts increases, people feel difficult to maintain their social contacts with merely memory. Aiming at helping people better manage their social contacts, a powerful...
There are many devices embedded in a smart home environment. It is a challenge to operate these devices due to the heterogeneity and the mobility of them. In this paper, we propose a context-aware resource management framework, which aims to (1) discover available resources and update the states of those devices according to the changes of contexts; (2) allocate suitable resources to meet the needs...
H.264/AVC is the latest international video coding standard, which provides a superior coding efficiency, compared with MPEG-4 and other previous standards. Context Adaptive Binary Arithmetic Coding (CABAC) was adopted by H.264/AVC and plays a very important role in improving the video coding efficiency. However, the coding speed of CABAC is restricted by high computational complexity, which becomes...
