A query analysis module receives a current query and processes the query against the document collection to select a set of documents that satisfy the query. A dynamic content organization module processes the document set according to defined parameters and a user selection or automatic selection of a desired topic arrangement to create various types of topic arrangements. These topic arrangements include supertopics, subtopics, perspective topic, and theme topic arrangements. A supertopic arrangement is a set of parent topics of a topic derived from the query, which parent topics best generalize the document set. A …
