## Facts and Figures

### POS Tagger models

**Enlgish POS tagger model (UD_English-EWT)**

Only `en_ewt-ud-train.conllu` file was used to train the model:

Precision, Recall and F1-Score against the test dataset `en_ewt-ud-test.conllu`

|Tokens |Precision  |Recall |F1-Score |

|-------|-----------|-------|---------|

| 25831 |0.93       |0.91   |0.92     |

Precision, Recall and F1-Score against the training dataset `en_ewt-ud-train.conllu`

|Tokens |Precision  |Recall |F1-Score |

|-------|-----------|-------|---------|

| 63785 |0.98       |0.98   |0.98     |

> **Precision** is "how useful the POS results are", and **Recall** is "how complete the results are". Precision can be seen as a measure of **exactness or quality**, whereas recall is a measure of **completeness or quantity**. https://en.wikipedia.org/wiki/Precision_and_recall

> The **F1 score** is the harmonic average of the precision and recall, where an F1 score reaches its best value at 1 (perfect precision and recall) and worst at 0. https://en.wikipedia.org/wiki/F1_score
