Book Summary:
We're drowning in a glut of information--how can we organize it all and present it in meaningful ways? Information Storage and Retrieval explores every facet of this complex problem facing programmers and system designers. Robert Korfhage addresses different components of the problem; for example, in addressing querying, he explores not just the familiar Boolean-logic queries but also vector queries, weighted queries, fuzzy queries, and probabilistic queries. The book also discusses techniques for determining the similarity of two documents, methods for incorporating user profiles into queries, and nontraditional ways of presenting query results. And, importantly, Korfhage includes measures for rating the effectiveness of information retrieval systems. While Information Storage and Retrieval won't necessarily tell you what solution will best suit your needs, it offers a useful survey of the numerous options so you can decide which are most appropriate for further consideration.The way information is stored, retrieved and displayed is changing. Simple bibliographic databases are giving way to unregulated and unorganized multimedia data repositories, which can give the user great difficulty when searching for information. A methodology is needed to keep all of this information in its various forms retrievable. This is the first modern survey of the field of information storage and retrieval to discuss how to work with information in all its varying forms. It shows information professionals how to handle full-text, graphics, video and audio, and how to distribute these massive databases over networks. |
