Stanford CoreNLP gives NullPointerException

Question

I\'m trying to get my head around the Stanford CoreNLP API. I wish to get a simple sentence to be tokenized using following code:

    Properties props = new          


        

Answer 1

This line retrieves sentence annotations.

List sentences = document.get(SentencesAnnotation.class);

But your pipeline contains only the tokenizer, not the sentence splitter.

Change the following line:

    props.put("annotators", "tokenize, ssplit"); // add sentence splitter
