Description

Information Retrieval Models and Concepts is a comprehensive book that educates on both the fundamental ideas and the rapidly expanding reach of Information Retrieval (IR) as a field. It presents an introduction to the fundamental topics underlying modern search technologies. This book includes algorithms, different data structures, indexing techniques, retrieval, and evaluation parameters. It addresses all kinds of concepts, algorithms-related IR for research purposes, especially in the Web search engine domain.
