    Abstract
    The emergence of information retrieval systems as a means of satisfying information needs has resulted in a large number of theoretical and practical ideas being introduced. These advancements provide the foundation for the theory of IR systems detailed in this book. Attention is also focused on the other areas of information science and how these differing theories interact and rely on each other. The book details algorithms in each process in the system, including those that are radically new in the retrieval process and those that are adaptable to the individual. New apporaches to evaluating information retrieval studying their performance are included
