Citizen journalism, also known as public or participatory journalism, is the act of citizens "playing an active role in the process of collecting, reporting, analyzing and disseminating news and information," according to the seminal report We Media: How Audiences are Shaping the Future of News and Information, by Shayne Bowman and Chris Willis. They say, "The intent of this participation is to provide independent, reliable, accurate, wide-ranging and relevant information that a democracy requires."[1] Citizen journalism should not be confused with civic journalism, which is practiced by professional journalists. Citizen journalism is a specific form of citizen media as well as user generated content.

Cloud Computing

• Web services

• Grid computing

• Network resources• Grid computing is a technology approach to

managing a cloud. In effect, all clouds are managed by a grid but not all grids manage a cloud. More specifically, a compute grid and a cloud are synonymous, while a data grid and a cloud can be different.

Tag Clouds

A tag cloud is a set of related tags with corresponding weights. Typical tag clouds have between 30 and 150 tags. The weights are represented using font sizes or other visual clues. Meanwhile, histograms or pie charts are most commonly used to represent approximately a dozen different weights. Hence, tag clouds can represent many more weights, though less accurately so. Also, frequently, tag clouds are interactive: tags are hyperlinks typically allowing the user to drill down on the data.

Semantic MediaWiki

• The WikiProject "Semantic MediaWiki" provides a common platform for discussing extensions of the MediaWiki software that allow for simple, machine-based processing of Wiki content. This usually requires some form of "semantic annotation," but the special Wiki environment and the multitude of envisaged applications impose a number of additional requirements.
