Gui for viewing and manipulating connected tag clouds

A computer readable storage medium storing a program of instructions executable by a machine to perform a method of visualizing and interacting with a joint term graph for a given topic X and two or more group Gs, each of the group Gs defined by a set of values d for a set of dimensions D, comprising:

• identifying one or more shared terms that are commonly used in two or more term graphs associate with respective two or more group Gs;
• presenting the shared terms;
• retrieving a term graph associated with said each group G associated with topic X;
• identifying a set of terms in the term graph associated with said each group G;
• displaying, by a processor, the set of terms as tags in a tag cloud for each group G, wherein multiple tag clouds are displayed;
• and
• linking, for each of the shared terms, a shared term to a tag in the tag clouds that represents a same term as the shared term.
