Modern information retrieval: The concepts and technology behind search

This book aims to provide a thorough and updated introduction to the key Information Retrieval (IT) concepts nad technologes behind search engines. IN the modern online world, seeking and finding informaiton of value is of paramound importance and, for this, people often refer to search engines because of their inherent effectiveness and simplicity. Search engines work because they are anchored on the field of IR--the primary goal of an IR system is to retrieve all teh documents as possible. This ambitious view of the problem naturally leads to a wealth of concepts and technologies, which are required to implement the search box paradigm. From parsing to indexing, clustering to classification, retrieval to ranking, and user feedback to retrieval evaluation, all of the most important concepts are carefully introduced and exemplified. The contents and structure of the book have been carefully designed by the two main authors, and the contributions of Eric Brown, Carlos Castillo, Marcos Gonçalves, David Hawking, Marti Jearst, Mounia Lalmas, Yoelle Maarek, Christian Middleton, Gonzalo Navarro, Dulce Ponceleón, Edie Rasmussen, Malcolm Slaney, and Nivio Ziviani greatly enrich the text with individual expertise from leaders in the field. This completely reorganized, revised and enlarged second edition of Modern INformaiton Retrieval contains four new chapters and double the number of pages nad bibliographic refrences of the first edition, and a companion website with teaching material. It will prove invaluable to students, professors, researchers, practitioners, and scholars of this fascinating field of IR.
