precision is the fraction of retrieved instances that are relevant, while recall (also known as sensitivity) is the fraction of relevant instances that are retrieved. I know their meaning but I don't know why it is called recall? I am not a native-speaker of English. I know recall means remember, then I don't know the relevance of this meaning to this concept! maybe coverage was better as it shows how many instances were covered...or even retrieve to mean how successful was to retrieve relevant data is better but recall?! to mean remember is not straightforward...Moreover sensitivity is also insensible for me!could you help me to associate these words to the concept and have a sense of them?
Performance measure: why it is called recall?
