CONCEPT
spreading activation
a method for searching associative networks, neural networks, or semantic networks; the search process is initiated by labeling a set of source nodes (e.g. concepts in a semantic network) with weights or "activation" and then iteratively propagating or "spreading" that activation out to other nodes linked to the source nodes.
