【书名】：Enriched Meanings: Natural Language Semantics with Category Theory

【作者】：Ash Asudeh, Gianluca Giorgolo

【年份】：2020年

【出版社】：牛津大学出版社

【简介】：走在语义学前沿的著作，将被视为可取代集合论作为数学基础的范畴论用于语义研究

This book develops a theory of enriched meanings for natural language interpretation that uses the concept of monads and related ideas from category theory, a branch of mathematics that has been influential in theoretical computer science and elsewhere. Certain expressions that exhibit complex effects at the semantics/pragmatics boundary live in an enriched meaning space, while others live in a more basic meaning space. These basic meanings are mapped to enriched meanings only when required compositionally, which avoids generalizing meanings to the worst case. Ash Asudeh and Gianluca Giorgolo show that the monadic theory of enriched meanings offers a formally and computationally well-defined way to tackle important challenges at the semantics/pragmatics boundary. In particular, they develop innovative monadic analyses of three phenomena - conventional implicature, substitution puzzles, and conjunction fallacies - and demonstrate that the compositional properties of monads model linguistic intuitions about these cases particularly well. The analyses are accompanied by exercises to aid understanding, and the computational tools used are available on the book's companion website. The book also contains background chapters on enriched meanings and category theory. The volume is interdisciplinary in nature, with insights from semantics, pragmatics, philosophy of language, psychology, and computer science, and will appeal to graduate students and researchers from a wide range of disciplines with an interest in natural language understanding and representation.

【书名】：Chinese as a Second Language Multilinguals’ Speech Competence and Speech Performance: Cognitive, Affective, and Sociocultural Perspectives

【作者】：Peijian Paul Sun

【年份】：2020年

【出版社】：Springer出版社

【简介】：This book offers a comprehensive and systematic review of multilingual L2 learners’ spoken Chinese, focusing on the dual dimensions of speech competence and speech performance. Specifically, by adopting a mixed-methods approach, it explores the cognitive, affective, and socio-cultural differences between intermediate and advanced multilingual learners’ L2 Chinese speech competence and speech performance. Drawing on a theoretical framework underpinned by the affective filter hypothesis, L2 willingness to communicate model, L2 motivational self-system, and L2 speech production models, this book not only contributes to our theoretical understanding of the roles of various factors in L2 Chinese speech competence and speech performance, but also offers practical insights into the implications for both teachers and learners in terms of how to minimize the gap between these two dimensions among L2 Chinese learners. It concludes with a discussion on the limitations of L2 Chinese speech and on future directions for the field.
