Summary:

There continue to be enormous changes and advancements in the indexing and retrieval of online health information made possible by the Internet. Coupled with this growth and integration of the World Wide Web into all aspects of information access and delivery, the topic of information retrieval has had a massive impact on consumer health information and genomics.

Totally rewritten, this new edition of Information Retrieval: A Health and Biomedical Perspective, Third Edition, provides an overview of the theory, practical applications, evaluation, and research directions of all aspects of medical information retrieval systems presented in four sections covering basic principles, state of the art, research systems, and special topics. Covering theory, practical applications, evaluation, and research directions, the book demystifies the jargon and defines terminology, models, resources, indexing, information retrieval, statistical and linguistic systems, and the clinical narrative. It also explains the role of multimedia, digital libraries, and the Internet.

This book details the technical state-of-the-art and focuses on research results in health/medical information retrieval. The increasing importance of health information retrieval makes the book an invaluable tool for those involved in this area, such as medical informaticians, computer scientists, library/information scientists, IT developers, and administrators from hospitals, companies, and universities.
