Simplified Named-Entity Extraction Pipeline in Idyl NLP

Idyl NLP 1.1.0 introduces a simplified named-entity extraction pipeline that can be created in just a few lines of code. The following code block shows how to make a pipeline to extract named-person entities from natural language English text in Idyl NLP.

NerPipelineBuilder builder = new NerPipeline.NerPipelineBuilder();
NerPipeline pipeline =;

EntityExtractionResponse response ="George Washington was president.");
for(Entity entity : response.getEntities()) {

When you run this code a single line will be printed to the screen:

Text: George Washington; Confidence: 0.96; Type: person; Language Code: eng; Span: [0..2);

Internally, the pipeline creates a sentence detector, tokenizer, and named-entity recognizer for the given language. Currently only person-entities for English is supported but we will be adding support for more languages and more entity types in the future. The goal of this functionality is to simplify the amount of code needed to perform a complex operation like named-entity extraction. The NerPipeline class is new in Idyl NLP 1.1.0-SNAPSHOT.
