In this publication, Melucci and Baeza-Yates current a wide-spectrum representation of contemporary learn ends up in complex components relating to info retrieval. Readers will locate chapters on e.g. aggregated seek, electronic ads, electronic libraries, discovery of unsolicited mail and evaluations, details retrieval in context, multimedia source discovery, quantum mechanics utilized to details retrieval, scalability demanding situations in net se's, and interactive info retrieval review. All chapters are written through recognized researchers, are thoroughly self-contained and entire, and are complemented through an built-in bibliography and topic index.
With this feature, the editors give you the latest survey of subject matters frequently now not addressed intensive in conventional (text)books on info retrieval. The presentation is meant for a large viewers of individuals attracted to info retrieval: undergraduate and graduate scholars, post-doctoral researchers, teachers, and commercial researchers.
