關於本電子書
This volume celebrates the twentieth anniversary of CLEF - the Cross-Language Evaluation Forum for the first ten years, and the Conference and Labs of the Evaluation Forum since – and traces its evolution over these first two decades. CLEF’s main mission is to promote research, innovation and development of information retrieval (IR) systems by anticipating trends in information management in order to stimulate advances in the field of IR system experimentation and evaluation.
The book is divided into six parts. Parts I and II provide background and context, with the first part explaining what is meant by experimental evaluation and the underlying theory, and describing how this has been interpreted in CLEF and in other internationally recognized evaluation initiatives. Part II presents research architectures and infrastructures that have been developed to manage experimental data and to provide evaluation services in CLEF and elsewhere. Parts III, IV and V represent the core of the book, presenting some of the most significant evaluation activities in CLEF, ranging from the early multilingual text processing exercises to the later, more sophisticated experiments on multimodal collections in diverse genres and media. In all cases, the focus is not only on describing “what has been achieved”, but above all on “what has been learnt”. The final part examines the impact CLEF has had on the research world and discusses current and future challenges, both academic and industrial, including the relevance of IR benchmarking in industrial settings.
Mainly intended for researchers in academia and industry, it also offers useful insights and tips for practitioners in industry working on the evaluation and performance issues of IR tools, and graduate students specializing in information retrieval.

關於作者
Nicola Ferro is an Associate Professor of Computer Science at the University of Padua, Italy. His research interests include information retrieval, its experimental evaluation, multilingual information access and digital libraries. He is the coordinator of the CLEF evaluation initiative, which includes more than 200 research groups around the globe involved in large-scale IR evaluation activities. He was also the coordinator of the EU Seventh Framework Programme Network of Excellence PROMISE on information retrieval evaluation.
Carol Peters, now Research Associate, was a Researcher at the Italian National Research Council’s “Istituto di Scienza e Tecnologie dell'Informazione.” Her main research activities focused on the development of multilingual access mechanisms for digital libraries and evaluation methodologies for cross-language information retrieval systems. She was leader of the EU Sixth Framework MultiMatch project, and coordinated the Cross-Language Evaluation Forum (CLEF) during its first ten years of activity. In 2009, in recognition of her work for CLEF, she was awarded the Tony Kent Strix Award.
