Abstract
Methods and systems generate content-categorization hierarchies and assign each content object to a set of nodes in the hierarchies. Each hierarchy includes a series of levels, each level including nodes which represent a categorization. A node in a top level is connected with multiple nodes in a lower level via a direct path. Each content object is assigned to a set of nodes, such that assignment to a lower-level node also results in assignment to each higher-level node in the lower-level node's direct path to a top of the hierarchy. Metadata of the content object is then modified to include a set of tags, each tag being a term from an assigned node. Tags are used to categorize the content object, summarize of the content object, identify recommended content objects, identify content objects responsive to a search query, and/or identify other content objects to supplement the content object.
