MLIR systems can facilitate the researchers and the end users to discover appropriate information in the preferred language. Due to the versatile applicability of MLIR systems, these systems require careful and thorough evaluations to demonstrate their desired performance. Therefore, the work reported in this book describes the greater efforts that are taken to develop a set of Metrics under Binary Retrieval and Ranked Relevance scheme for Evaluating the Performance of MLIR Systems. An Empirical and Statistical analysis is done to validate the proposed metrics under specified scheme of IR systems.
