The parser will then be able to read the models from that jar file. For example, in the distribution, the models are included in stanford-parser-2.0.4-models.jar The easiest way to access these models is to include this file in your classpath.
#Stanford headfinder how to#
I am not sure how to "provide the appropriate HeadFinder". In recent distributions, the models are included in a jar file inside the parser distribution. Parameters: t - The tree to display printTree public void printTree ( Tree t, java.io.PrintWriter pw) Prints the tree, with an empty ID. This and other options are handled by specifying the -tlpp flag, which lets you choose the class for a TreebankLangParserParams. hf - The HeadFinder used in printing output Method Detail printTree public void printTree ( Tree t) Prints the tree to the default PrintWriter. An appropriate HeadFinder needs to be provided. Example usage for Java HeadFinder fields. It is possible to train the Shift-Reduce Parser for languages other than English. Java HeadFinder fields, constructors, methods, implement or subclass. Implements a variant on the HeadFinder found in Michael Collins 1999 thesis. I am trying to train a constituency parser for Portuguese (from the terminal), but the instructions are rather vague (or I am too inexperienced).
