By identifying the opinion leaders, companies or governments can manipulate the selling or guiding public opinion, respectively. Additionally, detecting the influential comments is able to understand the source and trend of public opinion formation. However, mining opinion...
This paper looks at the potential of information visualization for multi-device co-located synchronous collaboration. That is, the capability of interactive graphical user interfaces to support face-to-face collaboration with networked devices such as large displays with motion recognition and mobile touchscreen devices. This is done by first considering how information visualization can be developed...
With the growth of data center (DC) size, the network topology becomes complicated and the maintenance workload increases significantly. To evaluate the workload, this paper presents a metric named MNT, Maintainability of Networking Topology. MNT consists of numbers of definitions of DC network model, such as cost of maintaining a node, cost of maintaining a link and recursive level. They can quantify...
Detecting the P2P swarm, analyzing their distribution is a challenging task, which has not received the deserved attention. In this paper, we demonstrate an active measurement methodology to continuously trace the real-world Bit Torrent and eMule/eDonkey swarms over the Internet from a stub network and for a long period of time. Our measurements achieve the ability of real-time scanning the online...
In the next-generation Internet architecture, more functionality will be placed in the data path of routers in the form of "services" and other packet processing features. This trend will increase the amount of state information that is maintained by system inside the network. In this paper, we present a framework for structuring and managing network state information distributed across...
