Book excerpt: Evaluation is a critical element in the development process of many natural language based systems. In this thesis, we will present critical analyses of standard evaluation methodologies applied in the following Natural Language Processing (NLP) domains: machine reading comprehension (MRC), question generation (QG), and open-domain dialogue. Generally speaking, systems from tasks like MRC are usually evaluated by comparing the similarity between hand-crafted references and system generated outputs using automatic evaluation metrics, thus these metrics are mainly borrowed from other NLP tasks that have been well-developed, such as machine translation and text summarization. Meanwhile, the evaluation of QG and dialogues is even a known open problem as such tasks do not have the corresponding references for computing the similarity, and human evaluation is indispensable when assessing the performance of the systems from these tasks. However, human evaluation is unfortunately not always valid because: i) human evaluation may cost too much and be hard to deploy when experts are involved; ii) human assessors can lack reliability in the crowd-sourcing environment. To overcome the challenges from both automatic metrics and human evaluation, we first design specific crowdsourcing human evaluation methods for these three target tasks, respectively. We then show that these human evaluation methods are reproducible, highly reliable, easy to deploy, and cost-effective. Additionally, with the data collected from our experiments, we measure the accuracy of existing automatic metrics and analyse the potential limitations and disadvantages of the direct application of these metrics. Furthermore, in allusion to the specific features of different tasks, we provide detailed statistical analyses on the collected data to discover their underlying trends, and further give suggestions about the directions to improving systems on different aspects.

Book excerpt: Teaching machines to understand human language documents is one of the most elusive and long-standing challenges in Artificial Intelligence. This thesis tackles the problem of reading comprehension: how to build computer systems to read a passage of text and answer comprehension questions. On the one hand, we think that reading comprehension is an important task for evaluating how well computer systems understand human language. On the other hand, if we can build high-performing reading comprehension systems, they would be a crucial technology for applications such as question answering and dialogue systems. In this thesis, we focus on neural reading comprehension: a class of reading comprehension models built on top of deep neural networks. Compared to traditional sparse, hand-designed feature-based models, these end-to-end neural models have proven to be more effective in learning rich linguistic phenomena and improved performance on all the modern reading comprehension benchmarks by a large margin. This thesis consists of two parts. In the first part, we aim to cover the essence of neural reading comprehension and present our efforts at building effective neural reading comprehension models, and more importantly, understanding what neural reading comprehension models have actually learned, and what depth of language understanding is needed to solve current tasks. We also summarize recent advances and discuss future directions and open questions in this field. In the second part of this thesis, we investigate how we can build practical applications based on the recent success of neural reading comprehension. In particular, we pioneered two new research directions: 1) how we can combine information retrieval techniques with neural reading comprehension to tackle large-scale open-domain question answering; and 2) how we can build conversational question answering systems from current single-turn, span-based reading comprehension models. We implemented these ideas in the DrQA and CoQA projects and we demonstrate the effectiveness of these approaches. We believe that they hold great promise for future language technologies.

Download or read book Zones of Control written by Pat Harrigan and published by MIT Press. This book was released on 2016-04-15 with total page 845 pages. Available in PDF, EPUB and Kindle. Book excerpt: A look at wargaming’s past, present, and future—from digital games to tabletop games—and its use in entertainment, education, and military planning. With examples from Call of Duty: Modern Warfare, Harpoon, Warhammer 40,000, and more! Games with military themes date back to antiquity, and yet they are curiously neglected in much of the academic and trade literature on games and game history. This volume fills that gap, providing a diverse set of perspectives on wargaming’s past, present, and future. In Zones of Control, contributors consider wargames played for entertainment, education, and military planning, in terms of design, critical analysis, and historical contexts. They consider both digital and especially tabletop games, most of which cover specific historical conflicts or are grounded in recognizable real-world geopolitics. Game designers and players will find the historical and critical contexts often missing from design and hobby literature; military analysts will find connections to game design and the humanities; and academics will find documentation and critique of a sophisticated body of cultural work in which the complexity of military conflict is represented in ludic systems and procedures. Each section begins with a long anchoring chapter by an established authority, which is followed by a variety of shorter pieces both analytic and anecdotal. Topics include the history of playing at war; operations research and systems design; wargaming and military history; wargaming’s ethics and politics; gaming irregular and non-kinetic warfare; and wargames as artistic practice.

Download or read book Transforming the Workforce for Children Birth Through Age 8 written by National Research Council and published by National Academies Press. This book was released on 2015-07-23 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: Children are already learning at birth, and they develop and learn at a rapid pace in their early years. This provides a critical foundation for lifelong progress, and the adults who provide for the care and the education of young children bear a great responsibility for their health, development, and learning. Despite the fact that they share the same objective - to nurture young children and secure their future success - the various practitioners who contribute to the care and the education of children from birth through age 8 are not acknowledged as a workforce unified by the common knowledge and competencies needed to do their jobs well. Transforming the Workforce for Children Birth Through Age 8 explores the science of child development, particularly looking at implications for the professionals who work with children. This report examines the current capacities and practices of the workforce, the settings in which they work, the policies and infrastructure that set qualifications and provide professional learning, and the government agencies and other funders who support and oversee these systems. This book then makes recommendations to improve the quality of professional practice and the practice environment for care and education professionals. These detailed recommendations create a blueprint for action that builds on a unifying foundation of child development and early learning, shared knowledge and competencies for care and education professionals, and principles for effective professional learning. Young children thrive and learn best when they have secure, positive relationships with adults who are knowledgeable about how to support their development and learning and are responsive to their individual progress. Transforming the Workforce for Children Birth Through Age 8 offers guidance on system changes to improve the quality of professional practice, specific actions to improve professional learning systems and workforce development, and research to continue to build the knowledge base in ways that will directly advance and inform future actions. The recommendations of this book provide an opportunity to improve the quality of the care and the education that children receive, and ultimately improve outcomes for children.
