Innovations in Information Retrieval: Perspectives for Theory and Practice

摘要

To navigate through the massively expanding amounts of information, systems of information retrieval are becoming more and more vital, including tagging, metadata, catalogues, search engines, and classification systems. The author have considered retrieval systems for all formats of information, physical and digital as well as for new and expanding formats such video, audio, photos, web pages, and some of the complex issues that these involve. The book covers a diverse range of topics including serendipity, semantic navigation, retrieval in fiction and music, folksonomies, social tagging, and web search engines. Most chapters review the literature over the last 20 years, with the authors adding their perspectives to the trends. In every area researched it was illuminating how radically information retrieval has changed through the digital age so far. I would have liked more forward-looking predictions and more ideas for future directions in this rapidly changing field. Many of the chapters concluded with a "call to action" or a hope that some of the issues and problems would be overcome.
