	Precision "точність": What fraction of the returned results are relevant to the information need?
	tp / len(chosen) = tp / (tp + fp)

Recall - "повнота": What fraction of the relevant documents in the collection were returned by the system?
	== sensitivity:
	tp / (tp + fn)

accuracy - "правильність":
	(tp + tn) / (tp + tn + fp + fn)
