18. A method comprising: providing a navigable visual representation of a taxonomy, the navigable visual representation reflecting a plurality of nodes of the taxonomy that have associated publications; generating statistics associated with an individual node of the taxonomy, wherein the statistics reflect a recent trend in a number of publications that are associated with the individual node; and facilitating user modification of the taxonomy, the facilitating comprising: determining that the recent trend is an increasing trend that indicates that the number of publications that are associated with the individual node is increasing, determining that there are a relatively large number of publications associated with the individual node, and responsive to determining that the trend is an increasing trend and that there are a relatively large number of publications associated with the individual node, displaying, on the navigable visual representation, a suggested modification to split the individual node by adding at least two nodes to the taxonomy as children of the individual node, wherein at least the facilitating is performed by a computing device.
