Feature extraction logic is operated on a digital source text to organize a machine memory into a source feature representation of one or more of a system, an apparatus, a process, and a composition of matter. The source feature representation is applied as a control sequence to a database management system for a digital database to produce a group of correlated feature representations that exceed an overall feature correlation threshold with the source feature representation. Transformation logic is operated on the correlated feature representations to produce a digital multiplex of graphical drawings depicting the correlated feature representations.
