  • Patent number: 8688751
    Abstract: A computer implemented method and system is provided for associating and extracting content artifacts from a graphical representation of electronic content. A multi-dimensional virtual lattice comprising one or more grid layers is created. The nodes of the multi-dimensional virtual lattice represent metadata acquired from predefined content criteria. Electronic content comprising content artifacts acquired from multiple content sources is graphically represented within the multi-dimensional virtual lattice using the grid layers. Each of the content artifacts from the electronic content attaches to one or more nodes of the multi-dimensional virtual lattice. A user provides search criteria comprising keywords. The content artifacts attached to nodes of the multi-dimensional virtual lattice whose metadata matches with the keywords are extracted and displayed to the user.
