Method Summary

void	readClassification(Graph graph, Classification labels, java.io.File input) Read from a given file a estimate of classifications for nodes in the given graph.
Classification	readClassification(Graph graph, java.lang.String nodeType, AttributeCategorical attribute, java.io.File input) Read from a given file a estimate of classifications for nodes in the given graph.

Method Detail

readClassification

Classification readClassification(Graph graph,
                                  java.lang.String nodeType,
                                  AttributeCategorical attribute,
                                  java.io.File input)

Read from a given file a estimate of classifications for nodes in the given graph. Return these classifications in a Classification object.

Parameters:

graph - The graph whose nodes are two be classified

nodeType - The nodeType which the classification object refers to

attribute - The categorial values to map classification-names against.

input - The file from which to read classifications

Returns:

A Classification object for the classifications read in. Nodes whose classifications were not in the given file are classified as index '-1'

readClassification

void readClassification(Graph graph,
                        Classification labels,
                        java.io.File input)

Read from a given file a estimate of classifications for nodes in the given graph. Fill these into the given Classification object.

Parameters:

graph - The graph whose nodes are two be classified

labels - The classification object to fill in with the read in labels. The calling function should lock the valuemap if no new labels are to be accepted.

input - The file from which to read classifications
