Class RaspGraphReader

java.lang.Object
  sem.graphreader.RaspGraphReader

All Implemented Interfaces:

GraphReader

public class RaspGraphReader
extends java.lang.Object
implements GraphReader

Graph reader for the default RASP format.

The RASP toolkit: http://ilexir.co.uk/2011/open-source-rasp-release/

The small files were parsed with: ./rasp.sh -m -p'-ogi -n10'

The large file was parsed with: ./rasp.sh -m -p'-og'

Constructor Detail

RaspGraphReader

public RaspGraphReader(java.lang.String inputPath,
                       boolean getAllParses)
                throws GraphFormatException

Throws:

GraphFormatException

Method Detail

parseLabel

public static java.util.LinkedHashMap<java.lang.String,java.lang.String> parseLabel(java.lang.String label)
                                                                             throws GraphFormatException

Parses a string that represents a token/lemma. It is designed to handle formats: lemma+suffix:id_POS, lemma+suffix:id, lemma. For example: algorithm+s:6_NOUN, algorithm+s:6_NOUN, algorithms Returns a LinkedHashMap with four fields: lemma, suffix, index, pos

Parameters:

label -

Returns:

Throws:

GraphFormatException

parseGr

public static java.util.LinkedHashMap<java.lang.String,java.lang.String> parseGr(java.lang.String line,
                                                                                 boolean simpleEdgeFormat)
                                                                          throws GraphFormatException

Parses a line that represents a GR and return a LinkedHashMap with the arguments. The hashmap has five keys: type, subtype, head, dependent, initialgr.

Parameters:

line -

Returns:

Throws:

GraphFormatException

hasNext

public boolean hasNext()

Check whether there are more graphs available.

Specified by:

hasNext in interface GraphReader

Returns:

True if there are more graphs available.

next

public Graph next()
           throws GraphFormatException

Get the next graph from the corpus.

Specified by:

next in interface GraphReader

Returns:

The next graph.

Throws:

GraphFormatException

nextSentence

public java.util.ArrayList<Graph> nextSentence()
                                        throws GraphFormatException

Specified by:

nextSentence in interface GraphReader

Returns:

List of graphs

Throws:

Specified by:

reset in interface GraphReader

Throws:

GraphFormatException

close

public void close()

Specified by:

close in interface GraphReader

main
