The Theory and Implementation of a Bidirectional Question Answering System


Book Description

Abstract: "This paper describes a question answering system which is a limited instance of the general bidirectional architecture suggested by Appelt (1987). The novel features of our approach include the use of a linguistically well-motivated set of functional features; a bidirectional grammar which encodes these features directly; a question answering program which uses the thematic organisation of the user's input to construct a cooperative reply; and a tactical generation component which can be used with Montague semantics."




Reversible Grammar in Natural Language Processing


Book Description

Reversible grammar allows computational models to be built that are equally well suited for the analysis and generation of natural language utterances. This task can be viewed from very different perspectives by theoretical and computational linguists, and computer scientists. The papers in this volume present a broad range of approaches to reversible, bi-directional, and non-directional grammar systems that have emerged in recent years. This is also the first collection entirely devoted to the problems of reversibility in natural language processing. Most papers collected in this volume are derived from presentations at a workshop held at the University of California at Berkeley in the summer of 1991 organised under the auspices of the Association for Computational Linguistics. This book will be a valuable reference to researchers in linguistics and computer science with interests in computational linguistics, natural language processing, and machine translation, as well as in practical aspects of computability.

Bidirectional Optimality Theory


Book Description

Bidirectional Optimality Theory (BiOT) emerged at the turn of the millennium as a fusion of Radical Pragmatics and Optimality Theoretic Semantics. It stirred a wealth of new research in the pragmatics‑semantics interface and heavily influenced e.g. the development of evolutionary and game theoretic approaches. Optimality Theory holds that linguistic output can be understood as the optimized products of ranked constraints. At the centre of BiOT is the insight that this optimisation has to take place both in production and interpretation, and that the production-interpretation cycle has to lead back to the original input. BiOT is now generally interpreted as a description of diachronically stable and cognitively optimal form–meaning pairs. It found applications beyond the semantics-pragmatics interface in language acquisition, historical linguistics, phonology, syntax, and typology. This book provides a state of the art overview of these developments. It collects nine chapters by leading scientists in the field.




Bidirectional Transformations


Book Description

Bidirectional transformations (BX) are means of maintaining consistency between multiple information sources: when one source is edited, the others may need updating to restore consistency. BX have applications in databases, user interface design, model-driven development, and many other domains. This volume represents the lecture notes from the Summer School on Bidirectional Transformations, held in Oxford, UK, in July 2016. The school was one of the final activities on the project "A Theory of Least Change for Bidirectional Transformations", running at the University of Oxford and the University of Edinburgh from 2013 to 2017 and funded by the UK Engineering and Physical Sciences Research Council. The five chapters included in this volume are a record of most of the material presented at the summer school. After a comprehensive introduction to bidirectional transformations, they deal with triple graph grammars, modular edit lenses, putback-based bidirectional programming, and engineering of bidirectional transformations.




Visual Question Answering


Book Description

Visual Question Answering (VQA) usually combines visual inputs like image and video with a natural language question concerning the input and generates a natural language answer as the output. This is by nature a multi-disciplinary research problem, involving computer vision (CV), natural language processing (NLP), knowledge representation and reasoning (KR), etc. Further, VQA is an ambitious undertaking, as it must overcome the challenges of general image understanding and the question-answering task, as well as the difficulties entailed by using large-scale databases with mixed-quality inputs. However, with the advent of deep learning (DL) and driven by the existence of advanced techniques in both CV and NLP and the availability of relevant large-scale datasets, we have recently seen enormous strides in VQA, with more systems and promising results emerging. This book provides a comprehensive overview of VQA, covering fundamental theories, models, datasets, and promising future directions. Given its scope, it can be used as a textbook on computer vision and natural language processing, especially for researchers and students in the area of visual question answering. It also highlights the key models used in VQA.
