The unregulated nature of the web means that anyone can make content available on the web, some of which could be harmful to children and unsuspecting adults. Content filtering is aimed at blocking out undesirable material from reaching the end user. Most existing software content filters make use an access control list which involves some sort of manual search, gathering and classification of undesirable...
The paper deals with the following topics: Internet; social science computing; computer-aided instruction; blogs; image retrieval; data security; query processing; ontology; e-commerce; data mining; Web service; and telecommunication computing.
We live in 21st century, a time when the speed of flow of information is the indicator of the quality of life. Therefore, it is rightly called the century of information. We need information in our everyday life, but we need to get it in bulk, with ease and with assured quality. The best and easiest way to get it is through the World Wide Web. Although there are a good number of search engines available...
SIP provides powerful capabilities for building audio conferencing services. However, the scalability for SIP-based telephony systems is mainly limited by both the capability of server and the availability of bandwidth. Based on the study of the SIP and P2P protocol, the paper proposes a pure hierarchical P2P architecture for SIP-based telephony systems. The architecture can dynamically increase the...
This paper conducts a quantitative analysis about cyber communication based on the data collected by questionnaires got from the Adolescent in Zhejiang, Hunan and Gansu. It finds that the internet has become a new field of daily communication, cyber communication will not only help adolescent to keep up with existing relations, but also expand their relative network.

"Web 2.0" refers to a second generation of web-based communities and online services, such as social-networking sites, wikis, and social indexing sites, which enable creativity, collaboration and sharing between users. With the rapid development of “Web 2.0”, network education is changing a lot. In contrast to traditional LMS-driven VLE solutions, PLE based on web2.0 takes a more natural...
As a new community, the virtual community is rising along with the development of Internet. Netizens establish and develop new forms of power relation through online interaction. In the condition of body absence, reconstructing rules, argument of opinions and collectively resisting become the main ways of power relation. Cyberpower is a flowing power. Its body, object and ways become uncertain.
The Web is now playing an important part in people's real-life activities. Scientists of not only computer science but also sociology and economics might be interested in mining on information directly related to real-life events, or news-related information on the Web. In this paper we propose a system to enable mining on news-related articles instead of raw web pages. There are functionally two...
The effectiveness of incentive mechanism in virtual community determines whether this virtual community can achieve its primary goals when it's first established. Meantime it's also a key factor to determine whether the community will exist over a long period of time as long as its profit is more than the cost. As a special virtual community, the campus virtual community provides students a platform...
The paper explores research concerned with improving aspects of the Web information gathering task. This type of task involves finding source of information on the Web, comparing different types of information, and re-finding information for reasoning and decision making. Research in Web information retrieval has explored visualization, clustering, and re-finding for improving the effectiveness of...
Recent developments in Graphics Processing Units (GPUs) have enabled inexpensive high performance computing for general-purpose applications. Due to GPU's tremendous computing capability, it has emerged as the co-processor of CPU to achieve a high overall throughput. CUDA programming model provides the programmers adequate C language like APIs to better exploit the parallel power of the GPU. K-nearest...
Internet is quickly becoming one of the most important parts in social life. As such people could pay more attention to the Internet events. However, it is not clear that which psychological factors influence Internet event attitudes. The present research was to investigate the mechanism of how Big-Five personality and regulatory emotional self-efficacy influence the attitude on Internet event. In...
Adolescent internet addiction is becoming a serious problem in China. The aim of the present study was to examine the relationship between resilience and internet addiction. Three hundred and forty-eight vocational technical school students from Hebei province completed the self-reported questionnaire. Structural Equation Model was used to explore the effects of resilience, perceived class climate,...
There is a growing body of evidence indicating that individual differences and Internet usage have an interaction relationship. We conducted a questionnaire survey of personal blog authors to extend this research to a popular online format for expression: blogging. The results indicate that bloggers and non-bloggers share lots of similarities in personality-related characters. Additionally, self-esteem...

The participants were 42 undergraduates who acted to come to Students Counseling Center for help for the first time. Five graduates of clinical psychology acted as their counselors. The counselors...
Video-on-Demand (VoD) is popular on the Internet for offering time-unconstrained viewing experience. In order to reduce their operational costs, VoD service providers call for assistance of the participating peers via employing peer-to-peer technologies. However, perfect viewing experiences perceived on the home DVD players are still hardly (or impractical) implemented on the Internet because of Internet...
In this paper we establish a general social intelligent algorithmic framework for packing problem under the help of the conception of social computing. In this framework, packing problem can be solved intelligently, with the same asymptotic bounds by applying the existing packing algorithms. More precisely, our framework is designed to intelligently adopt the most proper one among all the given existing...
