Method Detail

createGraphs

public void createGraphs()

Description copied from class: DocumentNGramGraph

Creates the graph of n-grams, for all the levels specified in the MinSize, MaxSize range.

Overrides:

createGraphs in class DocumentNGramGraph

createSymEdgesConnecting

public void createSymEdgesConnecting(Graph gGraph,
                                     java.lang.String sStartNode,
                                     java.util.List lOtherNodes,
                                     java.util.HashMap hAppearenceHistogram)

Creates an edge in [gGraph] connecting [sStartNode] to each node in the [lOtherNodes] list of nodes, as well as other nodes to [sBaseNode]. If an edge exists, its weight is increased by [iIncreaseWeight], else its weight is set to [iStartWeight]

Parameters:

gGraph - The graph to use

sStartNode - The node from which all edges begin

lOtherNodes - The list of nodes to which sBaseNode is connected. The list MUST BE ORDERED ASCENDINGLY based on distance from the sStartNode.

hAppearenceHistogram - The histogram of appearences of the terms

main
