A data processing system for managing a multiplicity of tags identified to indicate content of a document, the data processing system comprising:

• one or more processors, a computer-readable storage device, and a computer-readable memory;
• first program instructions to identify one or more groups of tags from the multiplicity of tags identified to indicate the content of the document, wherein the tags in each of the groups are sufficiently similar in meaning to each other to indicate same subject matter within the content of the document;
• second program instructions to identify one or more representative tags in each of the groups to represent the respective one or more groups of tags;
• and
• third program instructions to display the one or more representative tags in a tag cloud and not displaying all other tags in the one or more groups, wherein the first program instructions, the second program instructions, and the third program instructions are stored on the computer-readable storage device for execution by at least one of the one or more processors via the computer-readable memory.
