StanfordParser

public StanfordParser(String parserModel,
                      boolean loadFromJar)

Creates a new StanfordParser using the provided model location. If loadFromJar is true, then the path is assumed to refer to a file within the currently running jar. This Parser can readily by used within a map reduce job by setting loadFromJar to true and including the parser model within the map reduce jar.

Method Detail

parseText

public String parseText(String header,
                        String document)

Each parse tree will be padded with new lines. If header is not null, then it will be first line of each parse tree, otherwise only padded parse trees will be returned.

Specified by:

parseText in interface Parser

Parameters:

header - The header text that should label each parsed tree

document - The raw text to be parsed

parseText

public String parseText(String header,
                        StringPair[] sentence)
