Quality Estimation for Machine Translation
Many applications within natural language processing involve performing text-to-text transformations, i.e., given a text in natural language as input, systems are required to produce a version of this text (e.g., a translation), also in natural language, as output. Automatically evaluating the output of such systems is an important component in developing text-to-text applications. Two approaches have been proposed for this problem: (i) to compare the system outputs against one or more reference outputs using string matching-based evaluation metrics and (ii) to build models based on human feedback to predict the quality of system outputs without reference texts. Despite their popularity, ref...
From Complex Sentences to a Formal Semantic Representation using Syntactic Text Simplification and Open Information Extraction
This work presents a discourse-aware Text Simplification approach that splits and rephrases complex English sentences within the semantic context in which they occur. Based on a linguistically grounded transformation stage, complex sentences are transformed into shorter utterances with a simple canonical structure that can be easily analyzed by downstream applications. To avoid breaking down the input into a disjointed sequence of statements that is difficult to interpret, the author incorporates the semantic context between the split propositions in the form of hierarchical structures and semantic relationships, thus generating a novel representation of complex assertions that puts a semant...
New Language Technologies and Linguistic Research
This book is a collection of the papers presented and discussed at the 11th Corpus Linguistics Symposium (ELC 2012), held at the Instituto de Ciências Matemáticas e de Computação (Institute of Mathematics and Computer Science) of the University of São Paulo, at São Carlos, Brazil. The sessions addressed the following six topics: Corpus Linguistics and Language Description; Translation, Terminology and Corpora; Spoken Language and Corpora; Natural Language Processing and Corpora; Corpus Annotation; and Corpora and Multiple Documents. These unique studies will inspire readers with an interest in Linguistics, and will provide motivation for conducting further research in the interdisciplinary area of Language Technologies and Linguistic Research.
Conversational AI
This book provides a comprehensive introduction to Conversational AI. While the idea of interacting with a computer using voice or text goes back a long way, it is only in recent years that this idea has become a reality with the emergence of digital personal assistants, smart speakers, and chatbots. Advances in AI, particularly in deep learning, along with the availability of massive computing power and vast amounts of data, have led to a new generation of dialogue systems and conversational interfaces. Current research in Conversational AI focuses mainly on the application of machine learning and statistical data-driven approaches to the development of dialogue systems. However, it is impo...
Applying Linguistics in Health Research, Education, and Policy
Researchers in applied linguistics have found medical and health contexts to be fertile grounds for study, from macro-levels of conceptual analyses to micro-levels of the "turn-by-turn." The rich array of health contexts include medical research itself, clinical encounters, medical education and training, caregivers and patients in everyday life – from the formal and ritualized to the ad hoc and ephemeral. This volume foregrounds the crucial role of applied linguists addressing real world problems, while simultaneously highlighting the varied ways that health can be understood as a rich site of language inquiry in its own right. Chapters cover a range of health topics including medical training, medical interaction, disability in education, health policy analysis and recommendations, multidisciplinary research teams, and medical ethics. While reporting and reflecting on their specific topics in clinical and health contexts, contributors also articulate their own hybrid identities as professional collaborators in health research, education, and policy.
Natural Language Processing for Social Media, Third Edition
In recent years, online social networking has revolutionized interpersonal communication. The newer research on language analysis in social media has been increasingly focusing on the latter's impact on our daily lives, both on a personal and a professional level. Natural language processing (NLP) is one of the most promising avenues for social media data processing. It is a scientific challenge to develop powerful methods and algorithms that extract relevant information from a large volume of data coming from multiple sources and languages in various formats or in free form. This book will discuss the challenges in analyzing social media texts in contrast with traditional documents. Researc...
Validity, Reliability, and Significance
Empirical methods are means to answering methodological questions of empirical sciences by statistical techniques. The methodological questions addressed in this book include the problems of validity, reliability, and significance. In the case of machine learning, these correspond to the questions of whether a model predicts what it purports to predict, whether a model's performance is consistent across replications, and whether a performance difference between two models is due to chance, respectively. The goal of this book is to answer these questions by concrete statistical tests that can be applied to assess validity, reliability, and significance of data annotation and machine learning ...
Translation, interpreting, cognition
Cognitive aspects of the translation process have become central in Translation and Interpreting Studies in recent years, further establishing the field of Cognitive Translatology. Empirical and interdisciplinary studies investigating translation and interpreting processes promise a hitherto unprecedented predictive and explanatory power. This collection contains such studies which observe behaviour during translation and interpreting. The contributions cover a vast area and investigate behaviour during translation and interpreting – with a focus on training of future professionals, on language processing more generally, on the role of technology in the practice of translation and interpreting, on translation of multimodal media texts, on aspects of ergonomics and usability, on emotions, self-concept and psychological factors, and finally also on revision and post-editing. For the present publication, we selected a number of contributions presented at the Second International Congress on Translation, Interpreting and Cognition hosted by the Tra&Co Lab at the Johannes Gutenberg University of Mainz.
Human Language Technologies – The Baltic Perspective
Throughout the last decade, the Baltic states have played an active role in regional and international language technology activities, supporting less-resourced languages in the digital age. This book presents the proceedings of the 7th International Conference: Human Language Technologies – The Baltic Perspective (Baltic HLT 2016), held in Riga, Latvia, in October 2016. Baltic HLT 2016 provided a forum for sharing ideas and recent advances in human language processing with a special focus on less-resourced languages. Papers selected for the conference cover a wide range of topics, including a general overview of language technology progress in the Baltic states, actual research topics in written and spoken language processing, the creation of language resources and their applications, and proposals for a European language platform. The book is divided into five sections: overview; speech technologies and corpora; machine translation; written language resources; and methods and tools for language processing. The book will be a useful resource, not only for Baltic language researchers, but also for those working with other less-resourced languages in Europe and beyond.
