Description

This lecture covers the implementation of Fagin's algorithm for information retrieval, focusing on parallel scanning of posting lists and aggregation of tf-idf scores. The algorithm aims to efficiently retrieve top-k documents by scanning posting lists and combining scores. It also discusses the theoretical basis and practical application of the algorithm.
