Information Retrieval Questions
The evaluation measure mean reciprocal rank (MRR) is a metric used to assess the effectiveness of information retrieval systems. It calculates the average of the reciprocal ranks of the first relevant document retrieved for a set of queries. In other words, MRR measures how well a system ranks the most relevant document at the top of the search results. A higher MRR value indicates better performance, with 1 being the perfect score.
