User interface for displaying document comparison information

Abstract

A user interface for use with a document comparison program that allows a user to efficiently and effectively examine results from the document comparison is described. The user interface has at least one frame for displaying one or more overview bars. Each overview bar represents a document. An overview bar includes sub-bands or segments where each segment represents a passage in the document that matches a passage in at least one other document. Each sub-band is assigned a color and the same color is used to highlight text or content in the passage that matches another passage. By activating the sub-band, e.g. a point-and-click operation using a mouse, the user can pull up the corresponding passage in another frame displaying content from the document. This activation is implemented through an internal link, such as an HTML hypertext link. The user can also activate the text portion in the document and bring up the matching passage in another document in another frame in the user interface. The two passages are displayed in a manner such that they can be easily compared. The two passages are also internally linked so that activating one passage will display the other passage.

Dependencies are inferred from the claim text.
