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.
Seminar paper from the year 2016 in the subject English Language and Literature Studies - Linguistics, grade: 1,0, University of Leipzig, language: English, abstract: This seminar paper is concerned with the linguistic concept of productivity. The term is defined and factors that limit productivity in linguistics are pointed out (Constraints on Productivity). Finally, the relevance of productivity for English lessons is shown, which should be interesting for teachers to be.
This book is a contribution to the study of morphological productivity, that is, the property of word-formation processes whereby new words are created to satisfy a naming need. It presents an up-to-date picture of this phenomenon, characterising its major attributes and addressing neighbouring theoretical concepts like availability, profitability or lexicalisation. Links are also established between those notions and N+N compounding, a word-formation process regarded as very productive but traditionally overlooked in studies of this type. Unlike other productivity surveys, mostly directed at affixation, a corpus of N+N compounds is here compiled to which the mainstream models of productivity are applied. This allows to detect the pros and cons of those proposals and to propose a model of productivity. Two measures, Indicator of Profitability (π) and Trend of Profitability (Π), are introduced which can be applied across word-formation processes and are able to compute their productivity based on semantic categories.
This book constitutes the refereed proceedings of the 12th International Conference on Software Reuse, ICSR 2011, held in Pohang, South Korea, in June 2011. The 16 revised full papers were carefully reviewed and selected from 43 submissions. They are presented together with one keynote, three workshop papers, a doctoral symposium report and two tutorials. Topics of interest are domain analysis and modeling; asset search and retrieval; architecture-centric approaches to reuse; component-based reuse; COTS-based development; generator-based techniques; domain-specific languages; testing in the context of software reuse; aspect-oriented techniques; model-driven development; reuse of non-code artifacts; reengineering for reuse; software product line techniques; quality-aspects of reuse; economic models of reuse; benefit and risk analysis, scoping; legal and managerial aspects of reuse; transition to software reuse; industrial experience with reuse; light-weight approaches; software evolution and reuse.
This book presents formal testplanning guidelines with examples focused on creating assertion-based verification IP. It demonstrates a systematic process for formal specification and formal testplanning, and also demonstrates effective use of assertions languages beyond the traditional language construct discussions Note that there many books published on assertion languages (such as SystemVerilog assertions and PSL). Yet, none of them discuss the important process of testplanning and using these languages to create verification IP. This is the first book published on this subject.
This book is designed for professionals and students in software engineering or information technology who are interested in understanding the dynamics of software development in order to assess and optimize their own process strategies. It explains how simulation of interrelated technical and social factors can provide a means for organizations to vastly improve their processes. It is structured for readers to approach the subject from different perspectives, and includes descriptive summaries of the best research and applications.
Covering a variety of areas including software analysis, design, coding and maintenance, this text details the research conducted since the 1970s in this fast-developing field before going on to define a computer program from the viewpoint of computing and cognitive psychology. The two essential sides of programming, software production and software understanding, are given detailed treatment, with parallels drawn throughout between studies on processing texts written in natural language and processing computer programs. Of particular interest to researchers, practitioners and graduates in cognitive psychology, cognitive ergonomics and computer science.
