Information Retrieval Questions
The precision-recall curve is a graphical representation that illustrates the trade-off between precision and recall for a given information retrieval system. It plots the precision values on the y-axis and the corresponding recall values on the x-axis. The curve shows how the precision of the system changes as the recall increases. It is commonly used to evaluate and compare the performance of different retrieval systems, particularly in cases where the balance between precision and recall is crucial, such as in information retrieval tasks like document retrieval or web search.
