@vntk/conlleval

CoNLL format evaluator for Node.

This repository was inspired by connlleval.py

Usage and Installation

Install using npm:

npm install @vntk/conlleval

Then calculate the metrics:

var conlleval = require('./conlleval');
var metrics = conlleval.measure_performance('./diff.txt');

console.log('CoNLL format evaluation:', metrics);

Result output:
