Abstract: An interactive interface for visualizing results from a search of a corpus of machine-readable documents, each of which is associated with at least one category of a category hierarchy. The interactive interface includes a page object generation component, a book generation component, a page turning component, a cone tree generation component, and a cone tree rotation component. The page object generation component generates for each document of the results a link page and a content page. The link page of each document includes at least a link to categories of a category cone tree, which visually represents the category hierarchy. The content page of each document includes a portion of the document. The book generation component generates a visual representation of the pages for the documents of the results as a book. The book includes a first area for displaying a first link page of a first document of the results and a second area for displaying a first content page of the first document.
