Given the Table 3 Average accuracies by the network flow method (NF), Manhattan distance (Man), skew divergence (skew div), and Jensen-Shannon divergence (JS) on different profiles: original ("raw"), Li  Our experiments use semantic profiles created directly from the word frequencies, as described earlier.
research has explored the possibility of generalizing this kind of "raw" data to a semantic profile that more appropriately reflects the coherent concepts expressed in the original set of weighted concept nodes.
