 A tag cloud with terms related to Web 2.0 A tag cloud or word cloud (or weighted list in visual design) is a visual depiction of user-generated tags, or simply the word content of a site, used typically to describe the content of web sites. Tags are usually single words and are typically listed alphabetically, and the importance of a tag is shown with font size or color. [1] Thus both finding a tag by alphabet and by popularity is possible. The tags are usually hyperlinks that lead to a collection of items that are associated with a tag.

Definition
 A word cloud of the content of this article. 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.

History The first use of tag clouds on a high-profile website was on the photo sharing site Flickr, created by Flickr co-founder and interaction designer Stewart Butterfield.[2] That implementation was based[citation needed] on Jim Flanagan's Search Referral Zeitgeist,[3] a visualization of Web site referrers. Tag clouds have also been popularized by Del.icio.us and Technorati, among others. Flickr is a photo sharing website and web services suite, and an online community platform, which is generally considered an early example of a Web 2. ...

The first published appearance of a tag cloud (or at least a weighted list) can be attributed to the "subconscious files" in Douglas Coupland's Microserfs (1995). In Lester Leaps Out, the Welsh poet Doug Lang uses the same logic of weighted texts to create a graphical word-map of jazz music. The poem appears in his book, Magic Fire Chevrolet(1980). Douglas Coupland (born December 30, 1961) is a major Canadian fiction writer as well as a playwright and visual artist. ...

Types
 A data cloud showing the population of each of the world's countries. Color visually separates the countries, font size indicates 2007 population. There are three main types of tag cloud applications in social software, distinguished by their meaning rather than appearance. In the first type, there is a tag cloud for each item whereas in the second type, we have global tag clouds where the frequencies are aggregated over all items and users.

In the first type, size represents the number of times that tag has been applied to a single item.[4] This is useful as a means of displaying metadata about an item that has been democratically 'voted' on and where precise results are not desired. A good example of this is Last.fm, which uses this method as a means of displaying the genre with which an artist or track has been tagged. Metadata is data about data. ...

In the second, more commonly used type, size represents the number of items to which a tag has been applied, as a presentation of each tag's popularity. Examples of this type of tag cloud are used on the image-hosting service Flickr and the blog aggregator Technorati. Look up popularity in Wiktionary, the free dictionary. ...

In the third type, tags are used as a categorization method for content items. Tags are represented in a cloud where larger tags represent the quantity of content items in that category.
More generally, the same visual technique can be used to display non-tag data[5], as in a word cloud or a data cloud.
Visual appearance
 A data cloud showing stock price movement. Color indicates positive or negative change, font size indicates percentage change. Tag clouds are typically represented using inline HTML elements. APML (Attention Profiling Markup Language) is often used to store and import/export Tag Clouds. The tags can appear in alphabetical order, in a random order, they can be sorted by weight, and so on. Some prefer to cluster the tags semantically[6][7] so that similar tags will appear near each other. Heuristics can be used to reduce the size of the tag cloud whether or not we are trying to cluster the tags.[7] Image File history File links Size of this preview: 800 × 292 pixelsFull resolution (1280 × 467 pixel, file size: 24 KB, MIME type: image/png) File historyClick on a date/time to view the file as it appeared at that time. ...

Data clouds A data cloud is a data display which uses font size and/or color to indicate numerical values[8] It is similar to a tag cloud[9] but instead of word count, displays data such as population or stock market prices. A stock market or (equity market) is a private or public market for the trading of company stock and derivatives of company stock at an agreed price; both of these are securities listed on a stock exchange as well as those only traded privately. ...
