4. A computer implemented method for managing taxonomies comprising: retrieving a first taxonomy comprising at least one first category and one or more second taxonomies, at least one second category being associated with at least one of the one or more second taxonomies; analyzing a set of content profiles for content of the first taxonomy using evidence terms from content items; generating, using a computer processor, a category profile for the at least one first category of the first taxonomy based at least in part on the analysis of the set of content profiles for content of the first taxonomy; and creating a new taxonomy by merging the first taxonomy with the second taxonomy based on a comparison of a first category profile of the at least one first category with a second category profile of the at least one second category, wherein the comparing comprises applying a comparator function that identifies a match when a comparison between category profiles is above a threshold value, wherein the first taxonomy, the one or more second taxonomies, and the new taxonomy each comprise a controlled vocabulary organized hierarchically to represent relationships between terms in the controlled vocabulary, and wherein categories of the first taxonomy, the one or more second taxonomies, and the new taxonomy each comprise at least one labeled vocabulary term, wherein the creation of the new taxonomy comprises a taxonomy workflow process including review and approval of a plurality of tasks in a specified order.
