Abstract [en]

For several NLP tasks, an important substep is the identification of noun phrases in running text. This has typically been done by “chunking” - a way of finding minimal noun phrases by token classification. However, chunking-like methods do not represent the fact that noun phrases can be nested. This paper presents a novel method of finding all noun phrases in a sentence, nested to an arbitrary depth, using the BERT model for token classification. We show that our proposed method achieves very good results for both Swedish and English.
