EDITING OF CONCEPT SUBNETWORKS WITH A MICROCOMPUTER‐BASED DISPLAY SYSTEM

A quick, clear, and consistent automatic graphic display system has been developed for easy editing of complex concept subnetworks using only a floppy diskette drive and a PET2001–8 microcomputer. Initially implemented using Farradane's relations, it has an underlying data structure that facilitates merging with a general concept network. The primary display format is an enhanced triangular matrix; concepts may be sorted according to a standard citation order, and the display may also be automatically ‘compressed’.
