Systems and methods are provided for organizing text content of one or more text passages, such as text passages obtained in response to a search query, and/or other text passages, using an organization based on concept terms obtained from the one or more text passages. A hierarchical structure is used to organize the documents in a way that informs the user about co-occurrence relations among terms that represent concepts, indicating the relative degree of occurrence and context of discussion of the terms within the search results. One or more candidate hierarchies may be generated, each with a different term in the most-dominant position. The one or more candidate hierarchies can be evaluated, and a hierarchy to be displayed can be selected based on the evaluation.
