Tag Clouds are visual representations of the tags, Course Tags, and Discipline Tags used to classify a set of bookmarks. Tag Clouds are sorted alphabetically, but the size of the individual tags in the tag cloud indicates the frequency with which the tag was used -- the more frequent the tag, the larger the size of that tag in the Tag Cloud. You can click on a tag in the Tag Cloud to filter the set of bookmarks by that tag.

You'll see four kinds of Tag Clouds in Scholar:  

• My Tag Cloud appears on the My Scholar Home page and in the My Bookmarks view. It shows the tags, Discipline Tags and Course Tags you have used to classify the bookmarks you have saved. Since only users in a course can see the Course Tags for that course, this is the only Tag Cloud where your Course Tags appear.
• User Tag Cloud appears on the User Bookmarks view for a particular user. It shows the tags and Discipline Tags that user has used to classify the bookmark she or he has added.
• Recent Tag Cloud appears on the All Bookmarks view and shows the most recently added tags and Discipline Tags.

• Popular Tag Cloud appears on the Popular URLs view and shows the tags and Discipline Tags used for the most popular bookmarked sites.
