For humans, understanding a natural language sentence or discourse is so effortless that we hardly ever think about it. For machines, however, the task of interpreting natural language, especially grasping meaning beyond the literal content, has proven extremely difficult and requires a large amount of background knowledge. This book focuses on the interpretation of natural language with respect to specific domain knowledge captured in ontologies. The main contribution is an approach that puts ontologies at the center of the interpretation process. This means that ontologies not only provide a formalization of domain knowledge necessary for interpretation but also support and guide the construction of meaning representations. We start with an introduction to ontologies and demonstrate how linguistic information can be attached to them by means of the ontology lexicon model lemon. These lexica then serve as basis for the automatic generation of grammars, which we use to compositionally construct meaning representations that conform with the vocabulary of an underlying ontology. As a result, the level of representational granularity is not driven by language but by the semantic distinctions made in the underlying ontology and thus by distinctions that are relevant in the context of a particular domain. We highlight some of the challenges involved in the construction of ontology-based meaning representations, and show how ontologies can be exploited for ambiguity resolution and the interpretation of temporal expressions. Finally, we present a question answering system that combines all tools and techniques introduced throughout the book in a real-world application, and sketch how the presented approach can scale to larger, multi-domain scenarios in the context of the Semantic Web.

Insomnia is the difficulty initiating or maintaining sleep, including poor quality or quantity of sleep, often leading to impaired functioning and development of chronic sleep disturbances. Insomnia affects up to 50% of the general population globally, of which approximately 10% suffer from chronic insomnia. However, according to the National Sleep Foundation, less that 20% of patients with insomnia and related sleep disorders use a pharmacological intervention, highlighting a significant treatment gap. Handbook of Insomnia provides clinically-applicable insight into this condition, delving into the causes of insomnia, available and emerging treatment options and patient-centered guidelines for improving sleep hygiene and adopting successful lifestyle adjustments. This concise, fully illustrated handbook is the ideal resource for busy medical professionals and trainees with an interest in best-practice, evidence-based approaches to the management of insomnia and related sleep disorders
This comprehensive text focuses on the social contexts of ageing, looking at the diversity of ageing and older people, and at different factors that are important to experiences of old age and ageing. It includes key chapters on: theoretical and methodological bases for the study of ageing demographic context of the 'ageing' population health and illness family and social networks formal and informal care and other services for older people. Providing an invaluable introduction to the major issues involved in the study of ageing, this book is essential reading for students of sociology, gerontology, social policy, health and social care, and professionals working with older people.
Many strategies fail not because they are improperly formulated but because they are poorly implemented. The Oxford Handbook of Strategy Implementation examines the crucial role of implementation in how business and managerial strategies produce returns. In this wide-ranging collection of essays, leading scholars address governance, resources, human capital, and accounting-based control systems, advancing our understanding of strategy implementation and identifying opportunities for future research on this important process.
Disruptive behavior is extremely common in normal and clinical populations. This book addresses its development, the newly grouped diagnoses associated with it and their bio-psycho-social causes and treatment. The past decade has seen a great deal of progress in the psychiatric and psychological literature, which has greatly advanced our understanding of these disorders. The book discusses state of the art studies of taxonomy, epidemiology, etiology, and treatment. Each chapter concludes with a thorough discussion of the clinical implications of this new information, exemplified by real case material. A whole chapter is devoted to the forensic implications of this important grouping of disorders. The chapter begins with a discussion of the exemplary cases in the legal literature, providing the clinician and the expert with a concise briefing of the legal underpinnings of these disorders which in essence seek to bring the world of medicine to the world of crime. The final chapter provides a concise summary of all preceeding chapter, summarizing what we have learned and showing the way into the future in terms of basic research, translational research and clinical practice. Sources and resources are provided for clinicians, researchers, teacher, primary care physicians, criminologists, forensic experts and interested lay people.
The persistence of poverty in advanced welfare states casts doubt on the fundamental operating procedures of income distribution and redistribution. What are the reasons for this apparent failure of the welfare state in alleviating poverty? Why are some countries more effective than others in this respect and what can explain these variations in effectiveness? Addressing one of the major puzzles in comparative welfare state research, this volume examines why there is income poverty in highly developed welfare states. Focusing on the basic safety net of the welfare state, it offers a systematic analysis of the effectiveness of minimum income schemes in a comparative study across three highly developed welfare states: Germany, Sweden and the United Kingdom. Blending insights from a combination of institutional information and quantitative data from income surveys, the author evaluates the causal mechanisms for the persistence of income poverty in highly developed welfare states and derives conclusions for political reforms
