Class AnnotationPipeline

java.lang.Object
  edu.stanford.nlp.pipeline.AnnotationPipeline

All Implemented Interfaces:

Annotator

Direct Known Subclasses:

StanfordCoreNLP

public class AnnotationPipeline
extends java.lang.Object
implements Annotator

This class is designed to apply multiple Annotators to an Annotation. The idea is that you first build up the pipeline by adding Annotators, and then you takes the objects you wish to annotate and pass them in and get in return a fully annotated object. Please see package level javadocs for sample usage and a more complete description.

At the moment this mainly serves as an example of using the system and actually more complex annotation pipelines are in their own classes that don't extend this one.

Method Detail

addAnnotator

public void addAnnotator(Annotator annotator)

annotate

public void annotate(Annotation annotation)

Run the pipeline on an input annotation. The annotation is modified in place

Specified by:

annotate in interface Annotator

Parameters:

annotation - The input annotation, usually a raw document

annotate

public void annotate(java.lang.Iterable<Annotation> annotations)

Annotate a collection of input annotations IN PARALLEL, making use of all available cores.

Parameters:

annotations - The input annotations to process

annotate

public void annotate(java.lang.Iterable<Annotation> annotations,
                     Function<Annotation,java.lang.Object> callback)

Annotate a collection of input annotations IN PARALLEL, making use of all available cores

Parameters:

annotations - The input annotations to process

callback - A function to be called when an annotation finishes. The return value of the callback is ignored

annotate

public void annotate(java.lang.Iterable<Annotation> annotations,
                     int numThreads)

Annotate a collection of input annotations IN PARALLEL, making use of threads given in numThreads

Parameters:

annotations - The input annotations to process

numThreads - The number of threads to run on

annotate

public void annotate(java.lang.Iterable<Annotation> annotations,
                     int numThreads,
                     Function<Annotation,java.lang.Object> callback)

Annotate a collection of input annotations IN PARALLEL, making use of threads given in numThreads

Parameters:

annotations - The input annotations to process

numThreads - The number of threads to run on

callback - A function to be called when an annotation finishes. The return value of the callback is ignored.

getTotalTime

protected long getTotalTime()

Return the total pipeline annotation time in milliseconds.

Returns:

The total pipeline annotation time in milliseconds

timingInformation

public java.lang.String timingInformation()

Return a String that gives detailed human-readable information about how much time was spent by each annotator and by the entire annotation pipeline. This String includes newline characters but does not end with one, and so it is suitable to be printed out with a println().

Returns:

Human readable information on time spent in processing.

main

public static void main(java.lang.String[] args)
                 throws java.io.IOException,
                        java.lang.ClassNotFoundException

Throws:

java.io.IOException

java.lang.ClassNotFoundException
