1. A computer-implemented network structure, comprising: a memory that stores instructions to create: a first node that is a semantic Janus unit, wherein the first node possesses an existing time-variable state; a second node containing informational contents; and a link between the first node and the second node, wherein the link contains relational contents that describes the relationship between the first node and the second node, wherein the first node carries out operations on the second node and on the link, wherein the existing time-variable state determines which operations are carried out, and wherein a pattern in an image is recognized by carrying out the operations.
