This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 semantic layer on top of the simplified sentences. In a second step, she leverages the semantic hierarchy of minimal propositions to improve the performance of Open IE frameworks. She shows that such systems benefit in two dimensions. First, the canonical structure of the simplified sentences facilitates the extraction of relational tuples, leading to an improved precision and recall of the extracted relations. Second, the semantic hierarchy can be leveraged to enrich the output of existing Open IE approaches with additional meta-information, resulting in a novel lightweight semantic representation for complex text data in the form of normalized and context-preserving relational tuples.

Book Synopsis Automatic Text Simplification by : Horacio Saggion
Download or read book Automatic Text Simplification written by Horacio Saggion and published by Morgan & Claypool Publishers. This book was released on 2017-04-25 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thanks to the availability of texts on the Web in recent years, increased knowledge and information have been made available to broader audiences. However, the way in which a text is written—its vocabulary, its syntax—can be difficult to read and understand for many people, especially those with poor literacy, cognitive or linguistic impairment, or those with limited knowledge of the language of the text. Texts containing uncommon words or longand complicated sentences can be difficult to read and understand by people as well as difficult to analyze by machines. Automatic text simplification is the process of transforming a text into another text which, ideally conveying the same message, will be easier to read and understand by a broader audience. The process usually involves the replacement of difficult or unknown phrases with simpler equivalents and the transformation of long and syntactically complex sentences into shorter and less complex ones. Automatic text simplification, a research topic which started 20 years ago, now has taken on a central role in natural language processing research not only because of the interesting challenges it posesses but also because of its social implications. This book presents past and current research in text simplification, exploring key issues including automatic readability assessment, lexical simplification, and syntactic simplification. It also provides a detailed account of machine learning techniques currently used in simplification, describes full systems designed for specific languages and target audiences, and offers available resources for research and development together with text simplification evaluation techniques.
Book Synopsis Semantics by : Igor? Aleksandrovi? Mel??uk
Download or read book Semantics written by Igor? Aleksandrovi? Mel??uk and published by John Benjamins Publishing. This book was released on 2012 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an innovative and novel approach to linguistic semantics, beginning with the idea that language can be described as a system for the expression of linguistic Meanings as particular surface forms or Texts. Semantics is specifically that system of rules that ensures a correct transition from a Semantic Representation of the Meaning of a family of synonymous sentences to the Deep Syntactic Representation of a particular sentence. Framed in the terms of Meaning-Text linguistics, this volume discusses in detail the problems of Semantic Representation including the semantic structure of utterances, the semantics of Causation in English, and communicative, or information, structure. Based on the author's life-long dedication to the study of the semantics and syntax of natural language, this book is a paradigm-shifting contribution to the language sciences whose originality and daring will make it essential reading for linguists, anthropologists, semioticians, and computational linguists.

The highly cited material, covers questions, imperatives, copular clauses, and existential sentences. It also includes essential research on sentence types, and explains central concepts in the theory of information structure and discourse structure, such as topics, cohesion and coherence, accessibility and discourse particles.
Book Synopsis The Semantics of Syntax by : Denis Bouchard
Download or read book The Semantics of Syntax written by Denis Bouchard and published by University of Chicago Press. This book was released on 1995-12 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last thirty years, most linguists and philosophers have assumed that meaning can be represented symbolically and that the mental processing of language involves the manipulation of symbols. Scholars have assembled strong evidence that there must be linguistic representations at several abstract levels—phonological, syntactic, and semantic—and that those representations are related by a describable system of rules. Because meaning is so complex, linguists often posit an equally complex relationship between semantic and other levels of grammar. The Semantics of Syntax is an elegant and powerful analysis of the relationship between syntax and semantics. Noting that meaning is underdetermined by form even in simple cases, Denis Bouchard argues that it is impossible to build knowledge of the world into grammar and still have a describable grammar. He thus proposes simple semantic representations and simple rules to relate linguistic levels. Focusing on a class of French verbs, Bouchard shows how multiple senses can be accounted for by the assumption of a single abstract core meaning along with background information about how objects behave in the world. He demonstrates that this move simplifies the syntax at no cost to the descriptive power of the semantics. In two important final chapters, he examines the consequences of his approach for standard syntactic theories.
Book Synopsis Semantics by : Igorʹ Aleksandrovič Melʹčuk
Download or read book Semantics written by Igorʹ Aleksandrovič Melʹčuk and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an innovative approach to linguistic semantics, starting from the idea that language is a mechanism for the expression of linguistic meanings as particular surface forms (texts). Semantics is that system of rules that ensures a transition from a Semantic Representation of the meaning of a family of synonymous sentences to the Deep-Syntactic Representation of a particular sentence. Framed in terms of Meaning-Text linguistics, this volume discusses the Deep-Syntactic Representation and the transition from Semantics to Deep-Syntax via Semantic paraphrasing (the equivalence amongst Semantic Representations), Deep-Syntactic paraphrasing (the equivalence amongst Deep-Syntactic Representations), and the passage between the two. A chapter is dedicated to the Explanatory Combinatorial Dictionary, a semantically based and co-occurrence-centered lexicon. Reflecting the author's life-long dedication to semantics and syntax, this book is a paradigm-shifting contribution to language studies whose originality and daring will make it essential reading for linguists, anthropologists, semioticians, and computational linguists.

Book Synopsis Multi-source, Multilingual Information Extraction and Summarization by : Thierry Poibeau
Download or read book Multi-source, Multilingual Information Extraction and Summarization written by Thierry Poibeau and published by Springer Science & Business Media. This book was released on 2012-08-14 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: Information extraction (IE) and text summarization (TS) are powerful technologies for finding relevant pieces of information in text and presenting them to the user in condensed form. The ongoing information explosion makes IE and TS critical for successful functioning within the information society. These technologies face particular challenges due to the inherent multi-source nature of the information explosion. The technologies must now handle not isolated texts or individual narratives, but rather large-scale repositories and streams---in general, in multiple languages---containing a multiplicity of perspectives, opinions, or commentaries on particular topics, entities or events. There is thus a need to adapt existing techniques and develop new ones to deal with these challenges. This volume contains a selection of papers that present a variety of methodologies for content identification and extraction, as well as for content fusion and regeneration. The chapters cover various aspects of the challenges, depending on the nature of the information sought---names vs. events,--- and the nature of the sources---news streams vs. image captions vs. scientific research papers, etc. This volume aims to offer a broad and representative sample of studies from this very active research field.
Book Synopsis Information Structure and Sentence Form by : Knud Lambrecht
Download or read book Information Structure and Sentence Form written by Knud Lambrecht and published by Cambridge University Press. This book was released on 1996-11-13 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Why do speakers of all languages use different grammatical structures under different communicative circumstances to express the same idea? Professor Lambrecht explores the relationship between the structure of the sentence and the linguistic and extra-linguistic context in which it is used. His analysis is based on the observation that the structure of a sentence reflects a speaker's assumption about the hearer's state of knowledge and consciousness at the time of the utterance. This relationship between speaker assumptions and formal sentence structure is governed by rules and conventions of grammar, in a component called 'information structure'. Four independent but interrelated categories are analysed: presupposition and assertion, identifiability and activation, topic, and focus.
Book Synopsis The Syntactic Process by : Mark Steedman
Download or read book The Syntactic Process written by Mark Steedman and published by MIT Press. This book was released on 2001-07-27 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers topics in formal linguistics, intonational phonology, computational linguistics, and experimental psycholinguistics, presenting them as an integrated theory of the language faculty. In this book Mark Steedman argues that the surface syntax of natural languages maps spoken and written forms directly to a compositional semantic representation that includes predicate-argument structure, quantification, and information structure without constructing any intervening structural representation. His purpose is to construct a principled theory of natural grammar that is directly compatible with both explanatory linguistic accounts of a number of problematic syntactic phenomena and a straightforward computational account of the way sentences are mapped onto representations of meaning. The radical nature of Steedman's proposal stems from his claim that much of the apparent complexity of syntax, prosody, and processing follows from the lexical specification of the grammar and from the involvement of a small number of universal rule-types for combining predicates and arguments. These syntactic operations are related to the combinators of Combinatory Logic, engendering a much freer definition of derivational constituency than is traditionally assumed. This property allows Combinatory Categorial Grammar to capture elegantly the structure and interpretation of coordination and intonation contour in English as well as some well-known interactions between word order, coordination, and relativization across a number of other languages. It also allows more direct compatibility with incremental semantic interpretation during parsing. The book covers topics in formal linguistics, intonational phonology, computational linguistics, and experimental psycholinguistics, presenting them as an integrated theory of the language faculty in a form accessible to readers from any of those fields.
Book Synopsis Semantics-Oriented Natural Language Processing by : Vladimir Fomichov A.
Download or read book Semantics-Oriented Natural Language Processing written by Vladimir Fomichov A. and published by Springer. This book was released on 2009-12-04 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gluecklich, die wissen, dass hinter allen Sprachen das Unsaegliche steht. Those are happy who know that behind all languages there is something unsaid Rainer Maria Rilke This book shows in a new way that a solution to a fundamental problem from one scienti?c ?eld can help to ?nd the solutions to important problems emerged in several other ?elds of science and technology. In modern science, the term “Natural Language” denotes the collection of all such languages that every language is used as a primary means of communication by people belonging to any country or any region. So Natural Language (NL) includes, in particular, the English, Russian, and German languages. The applied computer systems processing natural language printed or written texts (NL-texts) or oral speech with respect to the fact that the words are associated with some meanings are called semantics-oriented natural language processing s- tems (NLPSs). On one hand, this book is a snapshot of the current stage of a research p- gram started many years ago and called Integral Formal Semantics (IFS) of NL. The goal of this program has been to develop the formal models and methods he- ing to overcome the dif?culties of logical character associated with the engineering of semantics-oriented NLPSs. The designers of such systems of arbitrary kinds will ?nd in this book the formal means and algorithms being of great help in their work.
Download or read book Computing Meaning written by Harry Bunt and published by Springer Science & Business Media. This book was released on 2008-07-03 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an in-depth view of the current issues, problems and approaches in the computation of meaning as expressed in language. Aimed at linguists, computer scientists, and logicians with an interest in the computation of meaning, this book focuses on two main topics in recent research in computational semantics. The first topic is the definition and use of underspecified semantic representations, i.e. formal structures that represent part of the meaning of a linguistic object while leaving other parts unspecified. The second topic discussed is semantic annotation. Annotated corpora have become an indispensable resource both for linguists and for developers of language and speech technology, especially when used in combination with machine learning methods. The annotation in corpora has only marginally addressed semantic information, however, since semantic annotation methodologies are still in their infancy. This book discusses the development and application of such methodologies.

Book Synopsis From Discourse to Logic by : Hans Kamp
Download or read book From Discourse to Logic written by Hans Kamp and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 730 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preface This book is about semantics and logic. More specifically, it is about the semantics and logic of natural language; and, even more specifically than that, it is about a particular way of dealing with those subjects, known as Discourse Representation Theory, or DRT. DRT is an approach towards natural language semantics which, some thirteen years ago, arose out of attempts to deal with two distinct problems. The first of those was the semantic puzzle that had been brought to contempo rary attention by Geach's notorious "donkey sentences" - sentences like If Pedro owns some donkey, he beats it, in which the anaphoric connection we perceive between the indefinite noun phrase some donkey and the pronoun it may seem to conflict with the existential meaning of the word some. The second problem had to do with tense and aspect. Some languages, for instance French and the other Romance languages, have two morphologically distinct past tenses, a simple past (the French Passe Simple) and a continuous past (the French Imparfait). To articulate precisely what the difference between these tenses is has turned out to be surprisingly difficult.
