The Probabilistic Relevance Framework (PRF) is a formal framework for document retrieval, grounded in work done in the 1970-80s, which led to the development of one of the most successful text-retrieval algorithms, BM25. In recent years, research in the PRF has yielded new retrieval models capable of taking into account structure and link-graph information. Again, this has led to one of the most successful web-search and corporate-search algorithms, BM25F. The Probabilistic Relevance Framework: BM25 and Beyond presents the PRF from a conceptual point of view, describing the probabilistic modelling assumptions behind the framework and the different ranking algorithms that result from its application: the binary independence model, relevance feedback models, BM25, BM25F. Besides presenting a full derivation of the PRF ranking algorithms, it provides many insights about document retrieval in general, and points to many open challenges in this area. It also discusses the relation between the PRF and other statistical models for IR, and covers some related topics, such as the use of non-textual features, and parameter optimization for models with free parameters. The Probabilistic Relevance Framework: BM25 and Beyond is self-contained and accessible to anyone with basic knowledge of probability and inference

Take a look at the incredible changes that take place in the natural world and learn all about the seasons! From the science behind the seasons and how they affect the world around them to myths and legends and practical tips to enjoy the seasons, it's all in this incredible book for children ages 7 to 9. In Vicky Woodgate’s follow-up title to The Magic of Sleep, children learn everything there is to know about the seasons. How do we measure a season? Why do we divide our years up and when did we start doing this? Are seasons the same for everyone? How do they work? All these questions and many more are covered in The Magic of Seasons, a practical guide to everything there is to know about the way we measure changes in weather, ecology, and daylight hours and how it affects us and the world around us.

Zoo Animal Welfare thoroughly reviews the scientific literature on the welfare of zoo and aquarium animals. Maple and Perdue draw from the senior author’s 24 years of experience as a zoo executive and international leader in the field of zoo biology. The authors’ academic training in the interdisciplinary field of psychobiology provides a unique perspective for evaluating the ethics, practices, and standards of modern zoos and aquariums. The book offers a blueprint for the implementation of welfare measures and an objective rationale for their widespread use. Recognizing the great potential of zoos, the authors have written an inspirational book to guide the strategic vision of superior, welfare-oriented institutions. The authors speak directly to caretakers working on the front lines of zoo management, and to the decision-makers responsible for elevating the priority of animal welfare in their respective zoo. In great detail, Maple and Perdue demonstrate how zoos and aquariums can be designed to achieve optimal standards of welfare and wellness.

An understanding of the work of zoos and aquariums is central to many programmes of study in wildlife conservation and more specialised programmes in zoo and aquarium science and management. This book is intended as a study and revision guide for students following these programmes. It contains 600 multiple-choice questions (and answers) set at three levels - foundation, intermediate and advanced - and grouped into 10 major topic areas. The book has been produced in a convenient format so that it can be used at any time in any place. It allows the reader to learn and revise the meaning of terms used in zoo and aquarium biology, the principles of animal husbandry and enclosure design, the behaviour of zoo visitors, the operation of captive breeding programmes, the international organisation of zoos, their legal regulation and much more.
