In this post, I am going to talk about precision and recall and their importance in information retrieval. First of all, let’s talk about what we mean by information retrieval. Suppose you wake up one morning and decide you want to make muffins for breakfast. You take out your laptop and search for “healthy muffin recipe” on Google. Then, you go through the search results, decide on a recipe and get started on it. This is an example of information retrieval where the search engine (Google in this case) retrieved the results for your search query “healthy muffin recipe”.
