Description

Segments given tokens into chunks (e.g. noun groups, verb groups, ...) and appends the found chunks to the stream.

---

Required input

Needs a stream with two string list properties:

1. A list of tokens
2. A list of part-of-speech tags (the Part-of-Speech processing element can be used for that)

---

Configuration

Assign the tokens and the part of speech tags to the corresponding stream property. To use this component you have to download or train an openNLP model: https://opennlp.apache.org/models.html

Output

Example:

Input:

tokens: ["John", "is", "a", "Person"]
tags: ["NNP", "VBZ", "DT", "NN"]

Output:

tokens: ["John", "is", "a", "Person"]
tags: ["NNP", "VBZ", "DT", "NN"]
chunks: ["John", "is", "a Person"]
chunkType: ["NP", "VP", "NP"])
