Class ToMapSymbolToAscii

java.lang.Object

gov.nih.nlm.nls.lvg.Flows.Transformation

gov.nih.nlm.nls.lvg.Flows.ToMapSymbolToAscii

All Implemented Interfaces:

java.lang.Cloneable

public class ToMapSymbolToAscii
extends Transformation
implements java.lang.Cloneable

This class converts Unicode punctuation and symbols to ASCII by table mapping. This is a pure table mapping method and is used to preserve the original document in NLP.

Users may define their own mapping in $LVG/data/Unicode/symbolMap.data.

Method Detail

Mutate

public static java.util.Vector<LexItem> Mutate(LexItem in,
                                               java.util.Hashtable<java.lang.Character,java.lang.String> symbolMap,
                                               boolean detailsFlag,
                                               boolean mutateFlag)

Performs the mutation of this flow component.

Parameters:

in - a LexItem as the input for this flow component

symbolMap - a hash table contains the unicode symbols mapping

detailsFlag - a boolean flag for processing details information

mutateFlag - a boolean flag for processing mutate information

Returns:

the results from this flow component - a collection (Vector) of LexItems

GetSymbolMapFromFile

public static java.util.Hashtable<java.lang.Character,java.lang.String> GetSymbolMapFromFile(Configuration config)

Read in unicode symbol to ASCII mapping list from configuration file

Parameters:

config - Configuratin object

Returns:

a hash table of unicode symbol mapping list

Get unicode synonym

Parameters:

inChar - an input character

unicodeSymbolMap - a hash table contains the unicode symbols

Returns:

the mapped unicode symbol string in ASCII

main
