Discovering hyponym relations among domain-specific terms is a fundamental task in taxonomy learning and knowledge acquisition. However, the great diversity of various domain corpora and the lack of labeled training sets make this task very challenging for conventional methods that are based on text content. The hyperlink structure of Wikipedia article pages was found to contain recurring network...
The Vehicular Ad hoc Networks (VANETs) have been recently introduced to provide high-speed Internet access to vehicles by deploying 802.11 enhanced Roadside Units (RSUs) along roads. However, few content downloading oriented RSU deployment strategies have been proposed. In this paper, we propose a new RSU deployment strategy for content downloading in VANETs. The encounters between vehicles and RSUs...
BitTorrent has generated a significant and continuously increasing portion of Internet traffic. Several designs have been recently proposed to reduce the BitTorrent traffic without sacrificing user downloading performance. However, Most of these designs only consider IPv4-only Internet, not thinking about IPv4/IPv6 hybrid network. With the exhaustion of IPv4 addresses and the development of IPv6,...
As the rapid development of Internet technology and the deployment of Internet multimedia applications, it's urgent to solve the QoS problems of the real-time multimedia services in the network for clients. This paper proposes a real-time video stream key frame identification algorithm for QoS, named RVKI. In this algorithm, the frame type of IP packets could be identified at the real-time multimedia...
In modern multimedia applications, images are often organized and managed by web sites or local applications with geographic information like GPS. But now this kind of multimedia applications doesn't come up in mobile communication environment. This paper proposes a method in image organization and sharing on mobile terminal whose resources are limited. We use the K-means clustering algorithm and...
Conventional content-based recommendation systems use different classifying algorithms to group items into several groups and for each group generate a ranking list of items. An important characteristic of conventional content-based recommendation systems is that they use the same ranking list to make recommendations for items in each group, ignoring differences among items inside of a group. The...
Online community (OC, or termed as "virtual community") provides a social sphere for people to share their information, knowledge and other resources. It is becoming an unprecedentedly ubiquitous online phenomenon. The contents which are jointly provided by participants are considered as public goods (Kollock, 1999). For public goods provided by collective action, there have been many papers...
We can envision that future sensor networks (WSNs) are ubiquitous, large-scale, interconnected, which we call worldwide sensor network (WWSN). Currently, most of the WSNs are working as isolated islands. Without sharing sensor data across different domains, the most important features of ubiquitous computing (e.g. context awareness) will not be easily achieved. For sharing among WWSN, the first nut...
