CogComp Curator

The Curator acts as a central server that can annotate text using several annotators. With this package, we can connect to the Curator to get those annotations and build our own NLP-driven application. This package contains code for interacting with Curator, using the data structures from cogcomo-core-utilities.

To use, first create a CuratorAnnotatorService to use the pipeline:

using edu.illinois.cs.cogcomp.curator.CuratorFactory;

AnnotatorService annotator = CuratorFactory.buildCuratorClient();

// Or alternatively to use the pipeline:
// using edu.illinois.cs.cogcomp.pipeline.main.PipelineFactory;
// AnnotatorService annotator = PipelineFactory.buildPipeline();

and then create a TextAnnotation component and add the Views you need:

TextAnnotation ta = annotator.createBasicTextAnnotation(corpusID, taID, "Some text that I want to process.");

Of course the real fun begins now! Using AnnotatorService you can add different annotation Views using their canonical name:

annotator.addView(ta, ViewNames.POS);
annotator.addView(ta, ViewNames.NER_CONLL);

These Views as well as the TextAnnotation object are now locally cached for faster future access.

You can later print the existing views:

System.out.println(ta1.getAvailableViews());

or access the views them directly:

TokenLabelView posView = (TokenLabelView) ta.getView(ViewNames.POS);

for (int i = 0; i < ta.size(); i++) {
    System.out.println(i + ":" + posView.getLabel(i));
}

Frequently Asked Questions

• Why curator tests take so much time/fail? We have some unit tests in this module which need connection to a remote curator system. Since it is often inaccessble to CIs, we skip them on Semaphore. If you’re running locally and seeing failures (or unexpected long delays on its tests) it must be that you don’t have connection to Curator (in which case you can just ignore it).
