Information Retrieval systems are systems that provide the ability to search for and find specific data or information within a collection.

Learning Objectives and Outcomes: By the end of this course students will be able to: Explain fundamental concepts and theories of information retrieval. Differentiate between and apply index compression and search effectiveness techniques. Compute weights and scores of documents within an IR system. Determine the effectiveness of an information retrieval system using a known document corpus. Construct a complete information retrieval system. Construct a web search system by integrating indexer, search engine, and web crawler (spider) components.
