The use of Web2.0 style technologies among Chinese civil society organizations

Based on a nationwide survey of more than 500 CSOs in China conducted in 2009, the research presented herein provides the first set of data and the first quantitative analysis regarding the use of Web2.0 technologies among Chinese CSOs. First, it attempts to answer the basic but crucial questions: Whether, on the whole, China’s CSOs use Web2.0 style technologies, and how widely different Web2.0 style technologies have been adopted among China’s CSOs. Second, it attempts to answer whether there is a regional difference (East China/Central China/West China) in the adoption of Web2.0 technologies; whether there is a difference in Web2.0 technologies adoption by financial resource (of CSOs); if yes, which group of CSOs are disadvantaged. This research found that most of the chosen Web2.0 style technologies have been widely adopted by CSOs. The use of Web2.0 style technologies and social media is likely to become a widespread phenomenon among CSOs in China. We found CSOs with medium financial support are more likely to use Web2.0, whereas CSOs with high financial support are left behind in the use of some Web2.0 technologies. More importantly, we found there is a regional inequality in the adoption of Web2.0 style technologies. CSOs in western China are left behind in the adoption of Web2.0. And CSOs in eastern China are more likely to use blog and Forum/BBS; CSOs in central China are more likely to upload video materials.     

COMSOC's chief information officer-technology serving the society

Previous President's Pages have touched on the wide range of activities conducted by the Communications Society. Many of these activities have evolved over many years, with beginnings even before personal computers and the Internet had become ubiquitous. With the advent of new information technologies, ComSoc realized it had an opportunity to significantly enhance existing services and introduce new services to its members. Achieving this would be no small task, and to provide proper focus on this challenge, the Board of Governors created the volunteer position of Chief Information Officer. This month's column is on the key role the Chief Information Officer (CIO) and the Information Technology (IT) department at ComSoc headquarters play in leveraging Information and Communications Technology (ICT) to keep up with the demands of our members for ever more valuable products and services? or "how to apply Web 2.0 to ComSoc 2.0."

The semantic Web: what, why, how, and when

The semantic Web aims to enrich the existing Web with a layer of machine-interpretable metadata so that a computer program can draw conclusions (that is, derive new information) predictably (that is, all programs that receive this information draw the same conclusions from it). The semantic Web has two motivators. The first is data integration, which is a significant bottleneck in many IT applications. The second motivator is more intelligent support for end users. If computer programs can infer consequences of information on the Web, they can give better support in finding information, selecting information sources, personalizing information, combining information from different sources and so on. To achieve these goals, we must meet the challenges of providing i) a syntax for representing metadata ii) vocabularies for expressing the metadata iii) metadata for lots of Web pages     

Devising Collective Knowledges for the Technical Writing Classroom: A Course-Based Approach to Using Web 2.0 Writing Technologies in Collaborative Work

Technical and professional writing pedagogies have traditionally understood collaborative writing as an aggregate, cooperative venture between writers and subject matter experts. In contrast, this tutorial argues that Web 2.0 technologies offer technical and professional communication pedagogies more advantageous conceptions and practices of collaborative writing. The tutorial analyzes how new media technologies create a different collaborative writing environment and then discusses how these environments help collaborative writing methods create an alternative writing situation. The study concludes by examining the outcomes of student Web 2.0 research projects and by offering technical and professional writing instructors new pedagogical strategies for teaching collaborative writing.      

Multilayer context cloud framework for mobile Web 2.0: a proposed infrastructure

Existing context‐aware systems focus only on characterizing the situation of an entity to exhibit the advantage of contextual information association, but they have no mechanism to facilitate the interoperation and reuse of contextual information. Cloud computing offers an adaptable and flexible solution for existing context‐aware applications, integrating Mobile Web 2.0 technologies. This work presents a multilayer context cloud framework (MCCF) that integrates Web 2.0 technologies into a mobile context‐aware system for use in a cloud computing environment. The proposed MCCF includes a context sensor layer, a context information layer, a context service layer, a context representation layer, a cloud computing layer, and a mobile Web 2.0 context‐aware Software as a Service layer. To demonstrate the feasibility of this approach, a Mobile Web 2.0‐based context‐aware Software as a Service platform, which is a cloud computing application based on MCCF, is implemented to provide continuous and context‐aware monitoring of a specific application.
