<p><b>Spreading activation</b> is a method for searching associative networks, <a href="page.php?w=Neural_network_%28biology%29">biological</a> and <a href="page.php?w=Neural_network_%28machine_learning%29">artificial neural networks</a>, or <a href="page.php?w=semantic_network">semantic network</a>s. 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.
