Book excerpt: This open access book introduces Vector semantics, which links the formal theory of word vectors to the cognitive theory of linguistics. The computational linguists and deep learning researchers who developed word vectors have relied primarily on the ever-increasing availability of large corpora and of computers with highly parallel GPU and TPU compute engines, and their focus is with endowing computers with natural language capabilities for practical applications such as machine translation or question answering. Cognitive linguists investigate natural language from the perspective of human cognition, the relation between language and thought, and questions about conceptual universals, relying primarily on in-depth investigation of language in use. In spite of the fact that these two schools both have ‘linguistics’ in their name, so far there has been very limited communication between them, as their historical origins, data collection methods, and conceptual apparatuses are quite different. Vector semantics bridges the gap by presenting a formal theory, cast in terms of linear polytopes, that generalizes both word vectors and conceptual structures, by treating each dictionary definition as an equation, and the entire lexicon as a set of equations mutually constraining all meanings.

Book Synopsis Embeddings in Natural Language Processing by : Mohammad Taher Pilehvar
Download or read book Embeddings in Natural Language Processing written by Mohammad Taher Pilehvar and published by Morgan & Claypool Publishers. This book was released on 2020-11-13 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Embeddings have undoubtedly been one of the most influential research areas in Natural Language Processing (NLP). Encoding information into a low-dimensional vector representation, which is easily integrable in modern machine learning models, has played a central role in the development of NLP. Embedding techniques initially focused on words, but the attention soon started to shift to other forms: from graph structures, such as knowledge bases, to other types of textual content, such as sentences and documents. This book provides a high-level synthesis of the main embedding techniques in NLP, in the broad sense. The book starts by explaining conventional word vector space models and word embeddings (e.g., Word2Vec and GloVe) and then moves to other types of embeddings, such as word sense, sentence and document, and graph embeddings. The book also provides an overview of recent developments in contextualized representations (e.g., ELMo and BERT) and explains their potential in NLP. Throughout the book, the reader can find both essential information for understanding a certain topic from scratch and a broad overview of the most successful techniques developed in the literature.
Book Synopsis Neuromimetic Semantics by : Harry Howard
Download or read book Neuromimetic Semantics written by Harry Howard and published by Elsevier. This book was released on 2010-08-10 with total page 555 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book attempts to marry truth-conditional semantics with cognitive linguistics in the church of computational neuroscience. To this end, it examines the truth-conditional meanings of coordinators, quantifiers, and collective predicates as neurophysiological phenomena that are amenable to a neurocomputational analysis. Drawing inspiration from work on visual processing, and especially the simple/complex cell distinction in early vision (V1), we claim that a similar two-layer architecture is sufficient to learn the truth-conditional meanings of the logical coordinators and logical quantifiers. As a prerequisite, much discussion is given over to what a neurologically plausible representation of the meanings of these items would look like. We eventually settle on a representation in terms of correlation, so that, for instance, the semantic input to the universal operators (e.g. and, all)is represented as maximally correlated, while the semantic input to the universal negative operators (e.g. nor, no)is represented as maximally anticorrelated. On the basis this representation, the hypothesis can be offered that the function of the logical operators is to extract an invariant feature from natural situations, that of degree of correlation between parts of the situation. This result sets up an elegant formal analogy to recent models of visual processing, which argue that the function of early vision is to reduce the redundancy inherent in natural images. Computational simulations are designed in which the logical operators are learned by associating their phonological form with some degree of correlation in the inputs, so that the overall function of the system is as a simple kind of pattern recognition. Several learning rules are assayed, especially those of the Hebbian sort, which are the ones with the most neurological support. Learning vector quantization (LVQ) is shown to be a perspicuous and efficient means of learning the patterns that are of interest. We draw a formal parallelism between the initial, competitive layer of LVQ and the simple cell layer in V1, and between the final, linear layer of LVQ and the complex cell layer in V1, in that the initial layers are both selective, while the final layers both generalize. It is also shown how the representations argued for can be used to draw the traditionally-recognized inferences arising from coordination and quantification, and why the inference of subalternacy breaks down for collective predicates. Finally, the analogies between early vision and the logical operators allow us to advance the claim of cognitive linguistics that language is not processed by proprietary algorithms, but rather by algorithms that are general to the entire brain. Thus in the debate between objectivist and experiential metaphysics, this book falls squarely into the camp of the latter. Yet it does so by means of a rigorous formal, mathematical, and neurological exposition – in contradiction of the experiential claim that formal analysis has no place in the understanding of cognition. To make our own counter-claim as explicit as possible, we present a sketch of the LVQ structure in terms of mereotopology, in which the initial layer of the network performs topological operations, while the final layer performs mereological operations.The book is meant to be self-contained, in the sense that it does not assume any prior knowledge of any of the many areas that are touched upon. It therefore contains mini-summaries of biological visual processing, especially the retinocortical and ventral /what?/ parvocellular pathways; computational models of neural signaling, and in particular the reduction of the Hodgkin-Huxley equations to the connectionist and integrate-and-fire neurons; Hebbian learning rules and the elaboration of learning vector quantization; the linguistic pathway in the left hemisphere; memory and the hippocampus; truth-conditional vs. image-schematic semantics; objectivist vs.

Book Synopsis The Legacy of János S. Petőfi by : Margarita Borreguero Zuloaga
Download or read book The Legacy of János S. Petőfi written by Margarita Borreguero Zuloaga and published by Cambridge Scholars Publishing. This book was released on 2019-02-06 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: János S. Petőfi (1931-2013) was one of the founders of Text Linguistics in Germany in the early ‘70s. He developed different text models, the most famous of which were the Text Structure World Structure Theory (TeSWeST) and Semiotic Textology. In this volume, some of his colleagues and disciples discuss his theoretical contributions to prove the enormous impact of his thoughts in the fields of linguistics, literary theory, rhetoric and semiotics. The essays here consider the notion of coherence, which Petőfi deemed to be the only sufficient condition for textuality, the relationships between his textual models and disciplines such as cognitive, computational and corpus linguistics, and his contributions to the analysis of literary and multimedial texts.
Book Synopsis Semantic Change and Collective Knowledge in 18th Century Britain by : John Regan
Download or read book Semantic Change and Collective Knowledge in 18th Century Britain written by John Regan and published by Bloomsbury Publishing. This book was released on 2023-07-27 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: An in-depth digital investigation of several 18th-century British corpora, this book identifies shared communities of meaning in the printed British 18th century by highlighting and analysing patterns in the distribution of lexis. There are forces of attraction between words: some are more likely to keep company than others, and how words attract and repel one another is worthy of note. Charting these forces, this book demonstrates how distant reading 18th-century corpora can tell us something new, methodologically defensible and, crucially, interesting, about the most common constructions of word meanings and epistemes in the printed British 18th century. In the case studies in this book, computation brings to light some remarkable facts about collectively-produced forms of meaning, without which the most common meanings of words, and the ways of knowing that they constituted, would remain matters of conjecture rather than evidence. Providing the first investigation of collective meaning and knowledge in the British 18th century, this interdisciplinary study builds on the existing stores of close reading, praxis, and history of ideas, presenting a view constructed at scale, rather than at the level of individual texts.

Available in PDF, EPUB and Kindle. Book excerpt: Euro-ParConferenceSeries The European Conference on Parallel Computing (Euro-Par) is an international conference series dedicated to the promotion and advancement of all aspects of parallel and distributed computing. The major themes fall into the categories of hardware, software, algorithms, and applications. This year, new and interesting topicswereintroduced,likePeer-to-PeerComputing,DistributedMultimedia- stems, and Mobile and Ubiquitous Computing. For the ?rst time, we organized a Demo Session showing many challenging applications. The general objective of Euro-Par is to provide a forum promoting the de- lopment of parallel and distributed computing both as an industrial technique and an academic discipline, extending the frontiers of both the state of the art and the state of the practice. The industrial importance of parallel and dist- buted computing is supported this year by a special Industrial Session as well as a vendors’ exhibition. This is particularly important as currently parallel and distributed computing is evolving into a globally important technology; the b- zword Grid Computing clearly expresses this move. In addition, the trend to a - bile world is clearly visible in this year’s Euro-Par. ThemainaudienceforandparticipantsatEuro-Parareresearchersinaca- mic departments, industrial organizations, and government laboratories. Euro- Par aims to become the primary choice of such professionals for the presentation of new results in their speci?c areas. Euro-Par has its own Internet domain with a permanent Web site where the history of the conference series is described: http://www.euro-par.org. The Euro-Par conference series is sponsored by the Association for Computer Machinery (ACM) and the International Federation for Information Processing (IFIP).
Book Synopsis Automatic SIMD Vectorization of SSA-based Control Flow Graphs by : Ralf Karrenberg
Download or read book Automatic SIMD Vectorization of SSA-based Control Flow Graphs written by Ralf Karrenberg and published by Springer. This book was released on 2015-06-12 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ralf Karrenberg presents Whole-Function Vectorization (WFV), an approach that allows a compiler to automatically create code that exploits data-parallelism using SIMD instructions. Data-parallel applications such as particle simulations, stock option price estimation or video decoding require the same computations to be performed on huge amounts of data. Without WFV, one processor core executes a single instance of a data-parallel function. WFV transforms the function to execute multiple instances at once using SIMD instructions. The author describes an advanced WFV algorithm that includes a variety of analyses and code generation techniques. He shows that this approach improves the performance of the generated code in a variety of use cases.

Book Synopsis Studying Religion, Past and Present by : Nickolas P. Roubekas
Download or read book Studying Religion, Past and Present written by Nickolas P. Roubekas and published by Bloomsbury Publishing. This book was released on 2024-09-05 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: Celebrating the contributions of Panayotis Pachis to the field, this book discusses the past, present, and future of the study of religion in antiquity and modernity. Panayotis Pachis has dedicated his celebrated career at the Aristotle University of Thessaloniki to the study of various aspects of ancient religions. The contents of this book reflect Pachis' conviction that the study of religious ideas and practices should be focused on three pillars: the study of history, the formulation and application of theoretical frameworks, and the utilization of traditional as well as innovative methodological tools. Chapters range from the scientific study of Roman-Graeco religions, cultural evolution, and neurocognitive theories in the history and study of religion, to a look at why we need an integrative approach to study religion, past and present.
Book Synopsis Joachim Lambek: The Interplay of Mathematics, Logic, and Linguistics by : Claudia Casadio
Download or read book Joachim Lambek: The Interplay of Mathematics, Logic, and Linguistics written by Claudia Casadio and published by Springer Nature. This book was released on 2021-04-21 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is dedicated to the life and work of the mathematician Joachim Lambek (1922–2014). The editors gather together noted experts to discuss the state of the art of various of Lambek’s works in logic, category theory, and linguistics and to celebrate his contributions to those areas over the course of his multifaceted career. After early work in combinatorics and elementary number theory, Lambek became a distinguished algebraist (notably in ring theory). In the 1960s, he began to work in category theory, categorical algebra, logic, proof theory, and foundations of computability. In a parallel development, beginning in the late 1950s and for the rest of his career, Lambek also worked extensively in mathematical linguistics and computational approaches to natural languages. He and his collaborators perfected production and type grammars for numerous natural languages. Lambek grammars form an early noncommutative precursor to Girard’s linear logic. In a surprising development (2000), he introduced a novel and deeper algebraic framework (which he called pregroup grammars) for analyzing natural language, along with algebraic, higher category, and proof-theoretic semantics. This book is of interest to mathematicians, logicians, linguists, and computer scientists.

This book was released on 2023-05-19 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: We are now at a point where 'analytical advances' permit researchers to theoretically and empirically formulate, model, and test many of the ideas pertaining to the working of Richard Florida's 'creative class' in interesting and new ways. The kind of advances we have in mind include, but are not limited to, recent developments in growth theory in economics, improvements in statistics and in regional science that permit researchers to analyze data in novel ways, and progress in computer science that allows researchers to take advantage of, for instance, natural language processing. The objective of this book is to demonstrate how new analytical advances permit one to have a richer and more nuanced understanding of the ways in which the creative class has functioned and the ways in which its abilities can be harnessed for the betterment of society at large.

Available in PDF, EPUB and Kindle. Book excerpt: Text is everywhere, and it is a fantastic resource for social scientists. However, because it is so abundant, and because language is so variable, it is often difficult to extract the information we want. There is a whole subfield of AI concerned with text analysis (natural language processing). Many of the basic analysis methods developed are now readily available as Python implementations. This Element will teach you when to use which method, the mathematical background of how it works, and the Python code to implement it.
Book Synopsis Quantum Physics and Linguistics by : Chris Heunen
Download or read book Quantum Physics and Linguistics written by Chris Heunen and published by OUP Oxford. This book was released on 2013-02-21 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: New scientific paradigms typically consist of an expansion of the conceptual language with which we describe the world. Over the past decade, theoretical physics and quantum information theory have turned to category theory to model and reason about quantum protocols. This new use of categorical and algebraic tools allows a more conceptual and insightful expression of elementary events such as measurements, teleportation and entanglement operations, that were obscured in previous formalisms. Recent work in natural language semantics has begun to use these categorical methods to relate grammatical analysis and semantic representations in a unified framework for analysing language meaning, and learning meaning from a corpus. A growing body of literature on the use of categorical methods in quantum information theory and computational linguistics shows both the need and opportunity for new research on the relation between these categorical methods and the abstract notion of information flow. This book supplies an overview of how categorical methods are used to model information flow in both physics and linguistics. It serves as an introduction to this interdisciplinary research, and provides a basis for future research and collaboration between the different communities interested in applying category theoretic methods to their domain's open problems.
