Recogito Flair NER Plugin

An (experimental) plugin to the Recogito annotation platform that adds Flair by Zalando Research as a Named Entity Recognition Engine.

The plugin consists of two parts:

1. a minimal Python script that takes a filename as input, runs NER with Flair, and writes JSON results to STDOUT
2. a Scala wrapper that implements the Recogito plugin interface, and calls out to the Python script via the command line

Pre-Requisites

Make sure Flair is installed on your system: pip install flair

Testing

To run just the Python script use

python plugins/recogito.plugins.ner.flair/parse.py {filename}

To test parsing throught the Scala wrapper run

sbt test

Compile and Deploy

• build the plugin using sbt package. This will create the .jar file target\recogito-plugin-ner-flair-0.1.jar.
• copy the .jar into a subfolder inside the Recogito /plugins folder
• copy the Python script to the same subfolder
• make sure Flair is installed on the Recogito server
