# precision-recall

Given two arrays of strings (don't have to be unique), will calculate the precision, recall and f1 values. Returned as an JSON object. If one of the arrays is empty (or falsy), will return { precision: 0, recall: 0, f: 0 }.

* Install using "npm install precision-recall" or "yarn add precision-recall"

```javascript

import precisionRecall from 'precision-recall';

// what we expect to get

const relevant = ['relevant1', 'relevant2'];

// what we actually got

const retrieved = ['relevant1', 'irrelevant1', 'irrelevant2'];

// call the func

const sentences = precisionRecall(relevant, retrieved);

// results in { precision: 0.3333333333333333, recall: 0.5, f: 0.4 }

```
