Method Detail

usage

public static void usage()

Prints the following usage message:
BuildIndex class in package pitt.search.semanticvectors
Usage: java pitt.search.semanticvectors.BuildIndex PATH_TO_LUCENE_INDEX
BuildIndex creates termvectors and docvectors files in local directory.
Other parameters that can be changed include vector length,
(number of dimensions), seed length (number of non-zero
entries in basic vectors), minimum term frequency,
and number of iterative training cycles.
To change these use the following command line arguments:
-dimension [number of dimensions]
-seedlength [seed length]
-minfrequency [minimum term frequency]
-numnonalphabetchars [number non-alphabet characters (-1 for any number)]
-trainingcycles [training cycles]
-docindexing [incremental|inmemory] Switch between building doc vectors incrementally"
(requires positional index) or all in memory (default case).
