A proposal for a formal model, Fragment Grammars, that treats productivity and reuse as the target of inference in a probabilistic framework. Language allows us to express and comprehend an unbounded number of thoughts. This fundamental and much-celebrated property is made possible by a division of labor between a large inventory of stored items (e.g., affixes, words, idioms) and a computational system that productively combines these stored units on the fly to create a potentially unlimited array of new expressions. A language learner must discover a language's productive, reusable units and determine which computational processes can give rise to new expressions. But how does the learner differentiate between the reusable, generalizable units (for example, the affix -ness, as in coolness, orderliness, cheapness) and apparent units that do not actually generalize in practice (for example, -th, as in warmth but not coolth)? In this book, Timothy O'Donnell proposes a formal computational model, Fragment Grammars, to answer these questions. This model treats productivity and reuse as the target of inference in a probabilistic framework, asking how an optimal agent can make use of the distribution of forms in the linguistic input to learn the distribution of productive word-formation processes and reusable units in a given language. O'Donnell compares this model to a number of other theoretical and mathematical models, applying them to the English past tense and English derivational morphology, and showing that Fragment Grammars unifies a number of superficially distinct empirical phenomena in these domains and justifies certain seemingly ad hoc assumptions in earlier theories.

Why our use of language is highly creative yet also constrained We use words and phrases creatively to express ourselves in ever-changing contexts, readily extending language constructions in new ways. Yet native speakers also implicitly know when a creative and easily interpretable formulation—such as “Explain me this” or “She considered to go”—doesn’t sound quite right. In this incisive book, Adele Goldberg explores how these creative but constrained language skills emerge from a combination of general cognitive mechanisms and experience. Shedding critical light on an enduring linguistic paradox, Goldberg demonstrates how words and abstract constructions are generalized and constrained in the same ways. When learning language, we record partially abstracted tokens of language within the high-dimensional conceptual space that is used when we speak or listen. Our implicit knowledge of language includes dimensions related to form, function, and social context. At the same time, abstract memory traces of linguistic usage-events cluster together on a subset of dimensions, with overlapping aspects strengthened via repetition. In this way, dynamic categories that correspond to words and abstract constructions emerge from partially overlapping memory traces, and as a result, distinct words and constructions compete with one another each time we select them to express our intended messages. While much of the research on this puzzle has favored semantic or functional explanations over statistical ones, Goldberg’s approach stresses that both the functional and statistical aspects of constructions emerge from the same learning mechanisms.
Why are there more English words ending in -ness than ending in -ity? What is it about some endings that makes them more widely usable than others? Can we measure the differences in the facility with which the various affixes are used? Does the difference in facility reflect a difference in the way we treat words containing these affixes in the brain? These are the questions examined in this book. Morphological productivity has, over the centuries, been a major factor in providing the huge vocabulary of English and remains one of the most contested areas in the study of word-formation and structure. This book takes an eclectic approach to the topic, applying the findings for morphology to syntax and phonology. Bringing together the results of twenty years' work in the field, it provides new insights and considers a wide range of linguistic and psycholinguistic evidence.
Speakers and learners, based on memory and experience, implicitly know that certain language elements naturally pair together. However, they also understand, through abstract and frequency-independent categories, why some combinations are possible and others are not. The frequency-grammar interface (FGI) bridges these two types of information in human cognition. Due to this interface, the sediment of statistical calculations over the order, distribution, and associations of items (the regularities) and the computation over the abstract principles that allow these items to join together (the rules) are brought together in a speaker’s competence, feeding into one another and eventually becoming superposed. In this volume, it is argued that a specific subset of both first and second language grammar (termed ‘combinatorial grammar’) is both innate and learned. While not derived from language usage, combinatorial grammar is continuously recalibrated by usage throughout a speaker’s life. In the domain of combinatorial grammar, both generative and usage-based theories are correct, each shedding light on just one component of the two that are necessary for any language to function: rules and regularities.
Structuring, or, as it is referred to in the title of this book, the art of structuring, is one of the core elements in the discipline of Information Systems. While the world is becoming increasingly complex, and a growing number of disciplines are evolving to help make it a better place, structure is what is needed in order to understand and combine the various perspectives and approaches involved. Structure is the essential component that allows us to bridge the gaps between these different worlds, and offers a medium for communication and exchange. The contributions in this book build these bridges, which are vital in order to communicate between different worlds of thought and methodology – be it between Information Systems (IS) research and practice, or between IS research and other research disciplines. They describe how structuring can be and should be done so as to foster communication and collaboration. The topics covered reflect various layers of structure that can serve as bridges: models, processes, data, organizations, and technologies. In turn, these aspects are complemented by visionary outlooks on how structure influences the field.
An effective, quantitative approach for estimating and managing software projects How many people do I need? When will the quality be good enough for commercial sale? Can this really be done in two weeks? Rather than relying on instinct, the authors of Software Measurement and Estimation offer a new, tested approach that includes the quantitative tools, data, and knowledge needed to make sound estimations. The text begins with the foundations of measurement, identifies the appropriate metrics, and then focuses on techniques and tools for estimating the effort needed to reach a given level of quality and performance for a software project. All the factors that impact estimations are thoroughly examined, giving you the tools needed to regularly adjust and improve your estimations to complete a project on time, within budget, and at an expected level of quality. This text includes several features that have proven to be successful in making the material accessible and easy to master: * Simple, straightforward style and logical presentation and organization enables you to build a solid foundation of theory and techniques to tackle complex estimations * Examples, provided throughout the text, illustrate how to use theory to solve real-world problems * Projects, included in each chapter, enable you to apply your newfound knowledge and skills * Techniques for effective communication of quantitative data help you convey your findings and recommendations to peers and management Software Measurement and Estimation: A Practical Approach allows practicing software engineers and managers to better estimate, manage, and effectively communicate the plans and progress of their software projects. With its classroom-tested features, this is an excellent textbook for advanced undergraduate-level and graduate students in computer science and software engineering.

For the near future, the recent predictions and roadmaps of silicon semiconductor technology all agree that the number of transistors on a chip will keep growing exponentially according to Moore's Law, pushing technology towards the system-on-a-chip (SOC) era. However, we are increasingly experiencing a productivity gap where the chip complexity that can be handled by current design teams falls short of the possibilities offered by technological advances. Together with growing time-to-market pressures, this drives the need for innovative measures to increase design productivity by orders of magnitude. It is commonly agreed that the solutions for achieving such a leap in design productivity lie in a shift of the focus of the design process to higher levels of abstraction on the one hand and in the massive reuse of predesigned, complex system components (intellectual property, IP) on the other hand. In order to be successful, both concepts eventually require the adoption of new languages and methodologies for system design, backed-up by the availability of a corresponding set of system-level design automation tools. This book presents the SpecC system-level design language (SLDL) and the corresponding SpecC design methodology. The SpecC language is intended for specification and design of SOCs or embedded systems including software and hardware, whether using fixed platforms, integrating systems from different IPs, or synthesizing the system blocks from programming or hardware description languages. SpecC Specification Language and Methodology describes the SpecC methodology that leads designers from an executable specification to an RTL implementation through a well-defined sequence of steps. Each model is described and guidelines are given for generating these models from executable specifications. Finally, the SpecC methodology is demonstrated on an industrial-size example. The design community is now entering the system level of abstraction era and SpecC is the enabling element to achieve a paradigm shift in design culture needed for system/product design and manufacturing. SpecC Specification Language and Methodology will be of interest to researchers, designers, and managers dealing with system-level design, design flows and methodologies as well as students learning system specification, modeling and design.
