Method Summary

static java.lang.String	getBoundaryCharacter()
static java.lang.String	IOBToString(java.util.List<CoreLabel> labeledSequence, java.lang.String prefixMarker, java.lang.String suffixMarker) Convert a list of labeled characters to a String.
static java.util.List<CoreLabel>	StringToIOB(java.util.List<CoreLabel> tokenList, java.lang.Character segMarker, boolean applyRewriteRules) Convert a String to a list of characters suitable for labeling in an IOB segmentation model.
static java.util.List<CoreLabel>	StringToIOB(java.lang.String string) This version is for turning an unsegmented string to an IOB input, i.e., for processing raw text.
