The Stanford CoreNLP Natural Language Processing Toolkit

The paper describes the design and use of Stanford CoreNLP, an extensible processing pipeline that provides core natural language analysis components. It emphasizes a simple, approachable design with straightforward interfaces so that a range of users can integrate robust natural language processing into their work.

The toolkit is widely used both in the research NLP community and among commercial and government users of open-source NLP technology. The authors suggest this broad adoption follows from its approachable design, robust and good-quality analysis components, and its avoidance of requiring a large amount of associated baggage.
