Constructor & Destructor Documentation

joshua.decoder.JoshuaDecoder.JoshuaDecoder ( String configFile )

Constructs a new decoder using the specified configuration file.

Parameters:

configFile Name of configuration file.

Here is the call graph for this function:

joshua.decoder.JoshuaDecoder.JoshuaDecoder ( ) [private]

Constructs an uninitialized decoder for use in testing.

This method is private because it should only ever be called by the getUninitalizedDecoder() method to provide an uninitialized decoder for use in testing.

Here is the caller graph for this function:

void joshua.decoder.JoshuaDecoder.changeBaselineFeatureWeights ( double[] weights )

Here is the call graph for this function:

Here is the caller graph for this function:

void joshua.decoder.JoshuaDecoder.changeDiscrminativeModelOnly ( String discrminativeModelFile )

Here is the call graph for this function:

void joshua.decoder.JoshuaDecoder.changeFeatureWeightVector	(	double[]	weights,
		String	discrminativeModelFile
	)

Sets the feature weight values used by the decoder.

This method assumes that the order of the provided weights is the same as their order in the decoder's configuration file.

Parameters:

weights Feature weight values

Here is the caller graph for this function:

void joshua.decoder.JoshuaDecoder.cleanUp ( )

Here is the caller graph for this function:

void joshua.decoder.JoshuaDecoder.decodeSentence	(	String	testSentence,
		String[]	nbests
	)

Decode a sentence. This must be non-parallel.

void joshua.decoder.JoshuaDecoder.decodeTestSet	(	String	testFile,
		String	nbestFile,
		String	oracleFile
	)		throws IOException

Decode a whole test set. This may be parallel.

Parameters:

testFile
nbestFile
oracleFile

Here is the call graph for this function:

Here is the caller graph for this function:

void joshua.decoder.JoshuaDecoder.decodeTestSet	(	String	testFile,
		String	nbestFile
	)

Here is the call graph for this function:

static JoshuaDecoder joshua.decoder.JoshuaDecoder.getUninitalizedDecoder ( ) [static]

Gets an uninitialized decoder for use in testing.

This method is called by unit tests or any outside packages (e.g., MERT) relying on the decoder.

Here is the call graph for this function:

JoshuaDecoder joshua.decoder.JoshuaDecoder.initialize ( String configFile )

Initialize all parts of the JoshuaDecoder.

Parameters:

configFile File containing configuration options

Returns:: An initialized decoder
