The chapter on artificial intelligence has been significantly expanded to include a host of related topics such as automatic summarization, question answering, natural language searching, and the semantic web.As in the first edition, Chu emphasizes principles and fundamentals. She reviews key concepts and major developmental stages of the field, and then systematically examines information representation methods, IRR languages, retrieval techniques and models, and internet retrieval systems. In addition, she explains the retrieval of multilingual, multimedia, and hyperstructured information and explores the user dimension and evaluation issues.
