Information organization and navigation by user-generated associative overlays

摘要

A method of linking together digital information objects of a digital information space includes creating an overlay. The overlay includes at least one concept node, each concept node expressing one concept. A digital information object in the digital information space is accessed. The digital information object is examined to determine if at least one concept in common with concepts expressed in concept nodes is included. If the digital information object and the overlay include at least one common concept, the digital information object is automatically and dynamically linked to each concept node expressing common concepts. A user may create an information node in the overlay representing the digital information object.
