Interactive interface for viewing retrieval results

An interactive interface for visualizing results from a search of a corpus of machine-readable documents, each document being associated with at least one category of a category hierarchy, the interactive interface operating on a computer system including a display, a processor coupled to a cursor control device and a memory storing instructions for the processor, the search returning results including at least one document of the corpus, the interactive interface comprising:

• a) a page object generation component coupled to the memory, the page object generation component generating for each document of the results a link page and a content page, the link page of each document including at least one link to at least one category of the category cone tree associated with the results, the content page of each document including a portion of the document;
• b) a book generation component coupled to the page object generation component, the book generation component generating and displaying on the display a representation of the pages for the documents of the results as a book, the book including 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;
• c) a page turning component responsive to the cursor control device, the page turning component causing a second link page of a second document of the results to be displayed in the first area and a second content page of the second document of the results to be displayed in the second area;
• d) a cone tree generation component coupled to the memory, the cone tree generation component generating and displaying the cone tree, the cone tree being perceptible as three dimensional and representing a portion of the category hierarchy, each category being represented as a node, the cone tree having a primary display position for displaying first category nodes associated with a first document;
• and
• e) a cone tree rotation component responsive to the page turning component, the cone tree rotation component causing second category nodes associated with the second document to be displayed in the primary viewing position.
