Method Detail

getExtractorFramesRare

public static Extractor[] getExtractorFramesRare(String identifier)
Get an array of rare word feature Extractor identified by a name. Note: Names used here must also be known in getExtractorFrames, so we can appropriately add error messages. So if you add a keyword here, add it there as one to be ignored, too. (In the next iteration, this class and ExtractorFrames should probably just be combined).

Parameters:
identifier - Describes a set of extractors for rare word features
Returns:
A set of extractors for rare word features
