Description
This lecture covers the architecture of text retrieval systems, user feedback, and indexing techniques for information retrieval, such as inverted files. It discusses the inverted file structure, addressing granularity, and access structures, including B+-Tree and Hashing. The lecture also explains Heap's Law, which relates the collection size to vocabulary size, and the payload of postings in information retrieval.
