‘Perched on the back of a sunlit chair was something about 9 inches tall and shaped rather like a plump toy penguin with a nose-job. It appeared to be wearing a one-piece knitted jumpsuit of pale grey fluff with brown stitching, complete with an attached balaclava helmet. From the face-hole of the fuzzy balaclava, two big, shiny black eyes gazed up at me trustfully. Kweep, it said quietly.’ When author Martin Windrow met the tawny owlet that he christened Mumble, it was love at first sight. Raising her from a fledgling, through adolescence and into her prime years, Windrow recorded every detail of their time living together (secretly) in a south London tower block, and later in a Sussex village. This is the touching, intriguing and eccentric story of their 15-year relationship, complete with photographs and illustrations of the beautiful Mumble. Along the way, we are given fascinating insight into the ornithology of owls – from their evolution and biology to their breeding habits and hunting tactics. The Owl Who Liked Sitting on Caesar is a witty, quirky and utterly charming account of the companionship between one man and his owl.

An instant New York Times bestseller! A New York Times Notable Book of 2023 Named a Best Book of 2023 by Publishers Weekly From the author of The Genius of Birds and The Bird Way, a brilliant scientific investigation into owls—the most elusive of birds—and why they exert such a hold on human imagination With their forward gaze and quiet flight, owls are often a symbol of wisdom, knowledge, and foresight. But what does an owl really know? And what do we really know about owls? Some two hundred sixty species of owls exist today, and they reside on every continent except Antarctica, but they are far more difficult to find and study than other birds because they are cryptic, camouflaged, and mostly active at night. Though human fascination with owls goes back centuries, scientists have only recently begun to understand the complex nature of these extraordinary birds. In What an Owl Knows, Jennifer Ackerman joins scientists in the field and explores how researchers are using modern technology and tools to learn how owls communicate, hunt, court, mate, raise their young, and move about from season to season. Ackerman brings this research alive with her own personal field observations; the result is an awe-inspiring exploration of owls across the globe and through human history, and a spellbinding account of the world’s most enigmatic group of birds.

After a slow incubation period of nearly 15 years, a large and growing number of organizations now have one or more projects using the Semantic Web stack of technologies. The Web Ontology Language (OWL) is an essential ingredient in this stack, and the need for ontologists is increasing faster than the number and variety of available resources for learning OWL. This is especially true for the primary target audience for this book: modelers who want to build OWL ontologies for practical use in enterprise and government settings. The purpose of this book is to speed up the process of learning and mastering OWL. To that end, the focus is on the 30% of OWL that gets used 90% of the time. Others who may benefit from this book include technically oriented managers, semantic technology developers, undergraduate and post-graduate students, and finally, instructors looking for new ways to explain OWL. The book unfolds in a spiral manner, starting with the core ideas. Each subsequent cycle reinforces and expands on what has been learned in prior cycles and introduces new related ideas. Part 1 is a cook's tour of ontology and OWL, giving an informal overview of what things need to be said to build an ontology, followed by a detailed look at how to say them in OWL. This is illustrated using a healthcare example. Part 1 concludes with an explanation of some foundational ideas about meaning and semantics to prepare the reader for subsequent chapters. Part 2 goes into depth on properties and classes, which are the core of OWL. There are detailed descriptions of the main constructs that you are likely to need in every day modeling, including what inferences are sanctioned. Each is illustrated with real-world examples. Part 3 explains and illustrates how to put OWL into practice, using examples in healthcare, collateral, and financial transactions. A small ontology is described for each, along with some key inferences. Key limitations of OWL are identified, along with possible workarounds. The final chapter gives a variety of practical tips and guidelines to send the reader on their way.

In 400 BC while SOCRATES the Greek philosopher who shaped Western philosophy and his student PLATO stroll through an enchanted fortress they encounter an extraordinary Being who possesses the key to immortality. Over 2000 years later SOCRATO SCHAPIRELLI a direct descendant of Socrates uncovers a secret competition in Boston whereby 3 courageous contestants, psychiatrist LUKE TALBOT, ophthalmologist MARNI RIVERS and performance artist JAMIE DAWNE vie to be chosen as The One. The victor will achieve the gift of immortality. To the ruthless scientist MARGOT PAYNE, head of the most powerful dynasty in America, her son JONATHAN and her daughter TARA, conquerors who will stop at nothing, the key in securing eternity for themselves and acquiring the secret to immortality lies with the capture of THE OWL, the extraordinary Being who has survived despite thousands of years of pursuit. A nefarious plan is launched to capture this wondrous Being and acquire the secret to its power; a force if unleashed threatens to change the course of the modern world. A deadly race begins in the sinister, threatening fortress known as The Tomb where nightmares come alive. Through trials by astonishing disasters and unimaginable battles, their inventive genius and relentless drive to survive bring them to a final, spine-chilling confrontation in the very heart of their domain - The Tomb with the clock ticking against devastating odds a confrontation in which Luke, Marni and Jamie gain triumph only at the last seconds as a shocking secret is finally revealed.

With the advent of the Semantic Web and Semantic Technologies, ontologies have become one of the most prominent paradigms for knowledge representation and reasoning. However, recent progress in the field faces a lack of well structured ontologies with large amounts of instance data due to the fact that engineering such ontologies requires a considerable investment of resources. Nowadays, knowledge bases often provide large volumes of data without sophisticated schemata. Hence, methods for automated schema acquisition and maintenance are sought. Schema acquisition is closely related to solving typical classification problems in machine learning, e.g. the detection of chemical compounds causing cancer. In this work, we investigate both, the underlying machine learning techniques and their application to knowledge acquisition in the Semantic Web.

An inspiring introduction to capture-and-release research, this mother-daughter story about owl conservation will spark curiosity in young nature, bird, and science lovers. Sova’s mother is a scientist who studies birds and their migratory patterns. Each night she goes into the woods to conduct research, and finally Sova is old enough to join her. Securing headlamps, Sova and her mother head into the woods to capture, measure, and release saw-whet owls. Through the quiet night, Sova learns about the patience, persistence, and excitement that comes with conservation efforts and scientific research. This heartwarming mother-daughter story is the perfect primer to conservation, science, and amazing owls!
