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. This book covers everything from what is a season and how it came to be and whether dinosaurs experienced seasons, to myths and legends, seasons at sea, and a timeline of seasons all around the world. This book is ideal for children with an interest in nature, weather, geography, and the natural world, and anyone who wants to learn all about the history and science behind what seems like such a simple part of our lives.

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.

Abnormal behaviour patterns, from the jumping and somersaulting of caged laboratory mice to the pacing of enclosed 'big cats', are displayed by many millions of farm, zoo, research and companion animals. Including new chapters and over 30 contributors, this book focuses on the causation and treatment of these environment-induced stereotypic behaviours, and their implications for animal welfare and normalcy of brain functioning. The book begins by taking an ethological perspective, focusing on the constraints captivity places on animals' normal behavioural repertoires, and the effects these have on specific motivational systems. It then addresses the role of dysfunction, particularly the impact of chronic stress and impoverished environments on brain functioning. The book then moves on to explore how stereotypic behaviours can be tackled, once they have emerged, using diverse techniques from environmental enrichment to pharmaceutical intervention. It concludes by giving a new definition for 'stereotypic behaviour', and a discussion of future research directions.

Katja’s fairy tale romance with her dentist comes to an abrupt end when she learns that he is having an affair. Just when it seems that things can’t get any worse, her husband is killed in a car accident. Filled with grief, Katja thinks she is going crazy, but then two mysterious men enter her life: Dr. Frederich Blank and Armin the fireman, whose uniform looks like it came from a costume shop. Armin cannot see Blank, who is recently deceased and has only returned to haunt the neighborhood in hope of visiting his wife one last time. Katja begins a relationship with Armin, which leads to serious consequences, just as holes begin appearing in Dr. Blank. When the doctor starts to fade away, Katja desperately applies bandages to patch his holes. In one moving scene, Blank visits his wife’s apartment and Katja, lifted up in the cherrypicker of Armin’s fire engine, watches the visit through the upper-floor window. But Katja quickly realizes that Blank’s wife cannot see him; she merely continues to kiss her new lover. Blank spends his remaining days easing Katja into her new role as a soon to be mother.
