The result format tagcloud, part of the Extension "Semantic Result Formats" extension, can be used to display result values in a tag cloud. It has been written by Jeroen De Dauw for WikiWorks and is partly based on code from the FolkTagCloud extension.

With the deployment of SRF 1.8 the tagcloud format will support template inclusion,a sphere widget, class parameter, and wordcloud widget.

Usage

A simple example - displaying a tag cloud of authors of books:

{{#ask:
 [[Category:Books]]
 |?Has author
 |format=tagcloud
}}

Displaying a tag cloud of things with the most related items. The pages themselves are also listed, as they are related to themselves. Depending on the cloud order, the biggest tags are shown first (tagorder=desc) and limited by the parameter limit=.

Styling support

Assigning cascading style sheet classes (classs=) to a tagcloud query will influence its positioning, width/height etc.. The width= and height= parameters are only recognized by a widget type output.

.demo-30-percent-width {
    width:30%;
    clear:both;
}

.demo-float-right {
    clear:both;
    float:right;
    margin-left:10px;
    margin-bottom:10px;
}

{{#ask:
 [[Category:Books]]
 |?Has author
 |format=tagcloud
 |class=demo-30-percent-width demo-float-right
}}

Template support

In a scenario where a page title is represented by a unique ID rather than a human readable title a inclusion template can be used to retrieve and replace a tag with a human readable name (stored as property-value pair). (See example Template:tagcloud.tag.title)

Wordcloud widget

The widget shows tags as word cloud map using d3.cloud.js plug-in. (see here)

Sphere widget

The sphere output implements some basic settings but for a more elaborate option set, please adjust the JavaScript accordingly. (See available options).

The plugin that is used to create the sphere output requires that tags are a link type entity therefore normal text (of type string etc.) entities need to be converted into a link type using a template (see above) that creates a wiki link (such as [[{{{1}}}]]). The class parameter can be used to position the tagcloud easily within a page.
