Throws:

java.lang.Exception

XeroxParcTaggerClient

public XeroxParcTaggerClient(gov.nih.nlm.nls.utils.GlobalBehavior pSettings)
                      throws java.lang.Exception

This is a constructor for TaggerClient

Parameters:

pSettings -

Throws:

java.lang.Exception

Method Detail

init

public void init(gov.nih.nlm.nls.utils.GlobalBehavior pSettings)
          throws java.lang.Exception

Method init

Parameters:

pSettings -

Throws:

java.lang.Exception

close

public void close()

Method close

Specified by:

close in interface TaggerInterface

tag

public void tag(Sentence pSentence)

Method tag implements the tagInterface for the xerox parc tagger client

Specified by:

tag in interface TaggerInterface

Parameters:

pSentence -

processTaggerInput

public void processTaggerInput(Sentence pSentence,
                               java.util.Vector pTaggerTokens)

Method processTaggerInput adds the tagger tag to each token of the input.

Parameters:

pSentence -

pTaggerTokens -

processXeroxParcTag

public void processXeroxParcTag(Token pToken,
                                java.lang.String pTaggerInput)

Method processXeroxParcTag marries the tagger's tag to the token.

Parameters:

pToken -

pTaggerInput -

convert

public static int convert(java.lang.String pTag)

Method convert converts XeroxParc part of speech tags to the part of speech tags we use.

Parameters:

pTag -

Returns:

int from Category.java

correctTheTag

public int correctTheTag(java.lang.String pString)

correctTheTag checks for a string, and corrects it to what we are expecting. There are cases where we know that the Xerox Parc tagger does a poor job of tagging. Known cases: In (initial caps) is tagged by the tagger as a noun rather than a prep. At (initial caps) is tagged by the tagger as a noun rather than a prep. run is never tagged as a verb by the tagger.

Parameters:

pString -

Returns:

pTag (Category.UNKNOWN if the tag is not to be changed )

finalize

protected void finalize()
                 throws java.lang.Throwable

Release any resources used for Tagger access upon object finalization. That is close the socket to the tagger.

Overrides:

finalize in class java.lang.Object

Throws:

java.lang.Throwable

main

public static final void main(java.lang.String[] argv)

This is a test main, whose purpose is to test the functionality of each method developed for this class. This main strives to test the boundary conditions as well as some sample common ways each public method is intended to be used.

Parameters:

argv - The command line input, tokenized
