In a computerized data mining context, user input relating to positive and negative information is incorporated into node proximity measurements on a weighted, directed graph. Starting from a source node, links are added to nodes for which positive feedback is received. Where negative information is received, a sink node is substituted for nodes receiving negative information. Nodes neighboring that sink node have links added to the sink. These changes yield an altered graph. Afterwards, proximity information is determined from the altered graph.
