Method and system for defining relationships among labels

In a content system where labels are used to organize content, relationships between labels may be defined. A relationship may be unidirectional or bidirectional. A label may have multiple relationships to or from other labels. When the user selects a first label, information corresponding to a second label may be displayed in accordance with the relationship between the first and second labels. Relationships between labels may also be inferred by examining the labels and the content associated with the labels.
