Method Detail

getPossibleTextLabelKeys

public static java.lang.Object[] getPossibleTextLabelKeys()

Return an array of a possible arguments to FancyLoader.loadTextLabels()

loadTextLabels

public static TextLabels loadTextLabels(java.lang.String script)

Try to load a TextLabels object 'foo' in one of these ways.

1. If 'foo' is "sampleK.train" or "sampleK.test" for K=1,2,3 then a hard-coded small sample TextLabels object will be returned.
2. If 'foo' is the name of a file, treat it as a bean shell script, and return the result of executing it.
3. If script is a file stem "foo" and a file "foo.base" exists, load a textBase from "foo.base" (one document per line, line name used as document id).
4. If script is a file stem "foo" and a directory "foo" exists, load a textBase from "foo" (one document per file).
5. If a file named "data.properties" is on the classpath, and 'foo' is the name of a file in the value of the parameter edu.cmu.minorthird.scriptDir, as defined in data.properties, treat that file as a bean shell script, and return the result of executing it. When the script is executed, the variables "dataDir" and "labelDir" will be bound to Files defined by edu.cmu.minorthird.dataDir and edu.cmu.minorthird.labelDir.

SGML markup in the files "foo/*" or "foo.base" will be interpreted as annotations iff "foo" matches the regex defined by edu.cmu.minorthird.sgmlPattern. After any SGML markup is interpreted, FancyLoader will look for additional labels in "foo.labels" or "foo.mixup", in that order.

Parameters:

script - the name of the bean shell script, directory, file, ...

Returns:

TextLabels object

getProperty

public static java.lang.String getProperty(java.lang.String prop)

                 throws bsh.EvalError,
                        java.io.IOException

Throws:
