Tóm tắt nội dung

It covers both classical IR models (like Boolean and vector space models) and web‑oriented retrieval techniques, including basics of web search and indexing. The book also discusses text classification, clustering, and machine learning methods applied to document collections, with clear examples and figures to illustrate key concepts. It explains evaluation methods for IR systems to measure effectiveness and compare approaches. Designed primarily for advanced undergraduate and graduate computer science courses, it also serves as a reference for researchers and practitioners in search technologies. Written from a computer science perspective by leading experts, this work blends theory and practical implementation of modern retrieval systems
