It presents a large number of techniques in great detail, supporting the explanations with detailed examples and critic reviews of work published in journals and conferences. Various NLP techniques can be used to, at least partially, improve the retrieval performance of IR models. Smith (1979), in an extensive survey of artificial intelligence techniques for information retrieval, stated that "the application of truncation to content terms cannot be done automatically to duplicate the use of truncation by intermediaries because any single rule [used by the conflation algorithm] has numerous exceptions" ( p. 223).
