12. The system of claim 11 , wherein the instructions are executable to rank the number of first nodes based on the relevance of the number of second nodes in the different relevance maps of the number of first nodes to the target user node include instructions executable to: create a different relevance map for each of the number of second nodes; and rank the number of first nodes and the number of second nodes based on a correlation between the different relevance maps of the number of first nodes and the relevance map of the target user node and a correlation between the different relevance maps of the number of second nodes and the relevance map of the target user node.
11. A system for relevance map linking, comprising: a processing resource in communication with a memory resource, wherein the memory resource includes a set of instructions, executable by the processing resource to: receive a query; identify a number of first nodes that meet the search criteria of the query; create a different relevance map for each of the number of first nodes wherein: the different relevance maps of the number of first nodes link the number of first nodes to a number of second nodes; the number of second nodes provide a context by which the number of first nodes are ranked; and each of the different relevance maps defines the relevance of the number of first nodes to a different particular one of the number of first nodes; rank the number of first nodes based on a relevance of the number of second nodes in the different relevance maps of the number of first nodes to a target user node; create a number of links, in a relevance map of the target user node, between the target user node and each of the number of first nodes that are ranked; assign a weight to each of the number of links wherein the weights represent a relevance of the number of nodes to the target user node and wherein the weights are expressed as numerical values; and adjust at least one of the weights in response to receipt of a user issued edit operation issued by a target user, wherein the edit operation includes a user provided value to adjust the at least one of the weights and an ID of a node to which the edit operation applies.
