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 take the objects you wish to annotate and pass them in and get back in return a fully annotated object. Please see the package level javadoc for sample usage and a more complete description.

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.

requirementsSatisfied

public java.util.Set<Annotator.Requirement> requirementsSatisfied()

Description copied from interface: Annotator

Returns a set of requirements for which tasks this annotator can provide. For example, the POS annotator will return "pos".

Specified by:

requirementsSatisfied in interface Annotator

requires

public java.util.Set<Annotator.Requirement> requires()

Description copied from interface: Annotator

Returns the set of tasks which this annotator requires in order to perform. For example, the POS annotator will return "tokenize", "ssplit".

Specified by:

requires in interface Annotator

main

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

Throws:

java.io.IOException

java.lang.ClassNotFoundException
