Adding custom entity extraction to my pipeline

Hola! We are working on a paper about entity extraction for Spanish person’s names, and have various models in the works, including one with CRF+BERT. My question is whether we could integrate this into Rasa stack as a custom entity extractor. How flexible is Rasa in this aspect? Is there an example of someone doing this in the past that I could look at? Best! Brandon

Hi @bubjanes,

indeed this would be possible. I’d like to point you to Custom Components which are capable of what you want to achieve.

A working example could be Naokos Regex Extractor but keep in mind that this was done in the past and some modifications would need to be done (e.g. regarding sparse/dense featurization).


Great! thanks @JulianGerhard!
