Details¶
This node performs namefinder using OpenNLP to easily detect named entities and numbers in text.
To be able to detect entities the Name Finder needs a model. The model is dependent on the language and entity type it was trained for.
The OpenNLP project offers a number of pre-trained name finder models which are trained on various freely available corpora. They can be downloaded at the OpenNLP download page.
