Beschreibung:
Dr. sc. nat. Christoph Meinel (1954) is President and CEO of the Hasso-Plattner-Institut for IT-Systems Engineering (HPI) and full professor (C4) for computer science at the University of Potsdam. His research field is Internet and Web Technologies and Systems. Beside he is a teacher at the HPI School of Design Thinking, a visiting professor at the Computer Science School of the Technical University of Beijing (China) and a research fellow of the interdisciplinary center SnT at the University of Luxembourg. Since 2008 he is program director of the HPI-Stanford Design Thinking Research Program. He is author or co-author of 10 text books and monographs and has published more than 350 per-reviewed scientific papers in highly recognised international scientific journals and conferences.
Dr. rer. nat. ing. Serge Linckels (1971) has studied computer-science in Luxembourg, France, and Germany. His research interests are Semantic Web, Multimedia Information Management and Retrieval, and the study and improvement of the way students learn, especially in a computer-based learning environment. He is the author of a textbook about algorithms and programming and has published over 20 peer-reviewed scientific papers in recognized international scientific journals and conferences. He is a computer-science teacher at the Lycée Technique d'Esch/Alzette, a technical high-school in Luxembourg. He lectures at the University of Luxembourg and is a researcher at the Hasso-Plattner-Institut (HPI) at the chair of Prof. Dr. Christoph Meinel.
This book introduces a new approach in designing E-Librarian Services. Such a system is able to retrieve multimedia resources from a digital library in a more efficient way than by browsing through an index, or by using a simple keyword search. It combines recent advances in multimedia information retrieval with aspects of human-machine interfaces. The user can enter his question in natural language. The premise is that more pertinent results would be retrieved if the search engine understood the sense of the user's query. The returned results are then logical consequences of an inference rather than of keyword matchings. An E-Librarian Service simulates a human librarian. Hence, it does not return the answer to the user's question, but it retrieves the most pertinent document(s), in which the user finds the answer to his question. Also, an E-Librarian Service always proposes a solution to the user, even if the system concludes that there is no exhaustive answer.
