This book was released on 1995 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prepositional phrase (PP) attachment is notorious for causing structural ambiguity problems in natural language processing. A structure like V-NP-PP where the PP is an optional locative PP forms a case in point. If we apply syntactic rules only, at least two different attachment sites will be possible: the noun phrase (NP) and the verb phrase (VP) that includes the verb and the NP. In some cases, only one of these attachments reflects a plausible interpretation of meaning. Previous approaches to disambiguation have achieved limited success. I propose and test a new Semantic + Syntactic Competitive Scoring (SSCS) approach with PP-attachment rules based on the selectional properties of individual prepositions plus five different verb types and the hypernyms (more abstract categories) of the polysemous meanings of nouns (for example, car IS A vehicle IS AN entity). A computerized classification program derives the verb types after examining VPs in large corpora. Noun hypernyms are taken from Princeton's WordNet, a computerized lexicon which already contains over 65,000 nouns. SSCS PP-attachment rules apply to VP ... NP ... PP structures, where the NP may be a complement of the verb or of an intervening preposition and any number of PPs may appear between the VP and the NP and between the NP and the PP to be attached. To develop and test these rules, I created separate randomized design data and test files from 1,648 VPs containing in/on/at prepositions. The VPs were taken from four different Penn Treebank preparsed texts. SSCS rules achieved an overall 92% success rate for the design data and an 82% success rate for the test files. However, a few modifications of underspecified verb types and alternative attachment sites plus a little more consideration of syntax and of the semantics of compound nouns and coordinate structures raise these success rates to 95% for the design data and 94% for the test files. Based on these results, I estimate that only 5-6% of all VPs containing in/on/at PPs need considerations from context of discourse and/or world knowledge to predict PP-attachment sites successfully. In addition to their implications for PP-attachment disambiguation, these results also have implication for other types of structural disambiguation and for future development of robust lexicons and parsers able to process multiple varieties of English in large corpora.

Download or read book Language Processing in Spanish written by Manuel Carreiras and published by Psychology Press. This book was released on 2013-05-13 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a set of contributions to the current flow of psycholinguistic research, with new and challenging data gathered from Spanish that may illuminate issues about the generality of language processing models. Although it is possible to find a considerable amount of papers on psycholinguistic research with the Spanish language published in English-speaking journals, unfortunately, the scientific community does not have access to an overview of psycholinguistics in Spain. This book overcomes these limitations because it brings together state-of-the-art descriptions of the research and theory of the different subareas of psycholinguistics currently being studied in Spain. Spanish, the third most widely-used language in the world, differs from English in a number of important respects. Since English has been predominant in psycholinguistic research, contrasting properties of Spanish may help to test the generality of language processing mechanisms and to refine their description. The set of contrasting features considered in this book includes acoustical and syllabic transparency, shallow orthography, a much richer morphology, flexibility in word order, less variability in intonational contours, and the existence of null pronominal subjects for inflected verbs. There are also interesting contrasts in the frequency of different linguistic units, whose impact on language processing is also evaluated. One of the main lines of argument throughout this book deals with the tension between universality and variation as a way of characterizing the functioning of language capacities and processes. The variety of topics covered by this book ranges from one end of the spectrum of language related behavior to the other: speech perception, lexical access in word recognition, relations between phonological and orthographic representations, sentence processing, discourse comprehension, and language production. All chapters focus on questions of general interest within each topic, and in most cases they appeal to one particular feature of the Spanish language that is relevant for a given question. Most chapters show the indisputable importance of crosslinguistic research in psycholinguistics to improve understanding on whether universal cognitive mechanisms and language specific routines underlie the ability of understanding and producing language.

Download or read book Dependency Parsing written by Sandra Kübler and published by Morgan & Claypool Publishers. This book was released on 2009 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dependency-based methods for syntactic parsing have become increasingly popular in natural language processing in recent years. This book gives a thorough introduction to the methods that are most widely used today. After an introduction to dependency grammar and dependency parsing, followed by a formal characterization of the dependency parsing problem, the book surveys the three major classes of parsing models that are in current use: transition-based, graph-based, and grammar-based models. It continues with a chapter on evaluation and one on the comparison of different methods, and it closes with a few words on current trends and future prospects of dependency parsing. The book presupposes a knowledge of basic concepts in linguistics and computer science, as well as some knowledge of parsing methods for constituency-based representations.

Download or read book Introduction to Natural Language Processing written by Jacob Eisenstein and published by MIT Press. This book was released on 2019-10-01 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: A survey of computational methods for understanding, generating, and manipulating human language, which offers a synthesis of classical representations and algorithms with contemporary machine learning techniques. This textbook provides a technical perspective on natural language processing—methods for building computer software that understands, generates, and manipulates human language. It emphasizes contemporary data-driven approaches, focusing on techniques from supervised and unsupervised machine learning. The first section establishes a foundation in machine learning by building a set of tools that will be used throughout the book and applying them to word-based textual analysis. The second section introduces structured representations of language, including sequences, trees, and graphs. The third section explores different approaches to the representation and analysis of linguistic meaning, ranging from formal logic to neural word embeddings. The final section offers chapter-length treatments of three transformative applications of natural language processing: information extraction, machine translation, and text generation. End-of-chapter exercises include both paper-and-pencil analysis and software implementation. The text synthesizes and distills a broad and diverse research literature, linking contemporary machine learning techniques with the field's linguistic and computational foundations. It is suitable for use in advanced undergraduate and graduate-level courses and as a reference for software engineers and data scientists. Readers should have a background in computer programming and college-level mathematics. After mastering the material presented, students will have the technical skill to build and analyze novel natural language processing systems and to understand the latest research in the field.

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 348 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.

Download or read book The Syntax of Silence written by Jason Merchant and published by . This book was released on 2001 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: A primary goal of contemporary theoretical linguistics is to develop a theory of the correspondence between sound (or gesture) and meaning. This sound-meaning correspondence breaks down completely in the case of ellipsis, and yet various forms of ellipsis are pervasive in natural language:words and phrases which should be in the linguistic signal go missing. How this should be possible is the focus of Jason Merchant's investigation. He focuses on the form of ellipsis known as sluicing, a common feature of interrogative clauses, such as in 'Sally's out hunting - guess what!'; and'Someone called, but I can't tell you who'. It is the most frequently found cross-linguistic form of ellipsis. Dr Merchant studies the phenomenon across twenty-four languages, and attempts to explain it in linguistic and behavioural terms.

Download or read book Second Language Sentence Processing written by Alan Juffs and published by Routledge. This book was released on 2014-12-02 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: This addition to the Cognitive Science and Second Language Acquisition series presents a comprehensive review of the latest research findings on sentence processing in second language acquisition. The book begins with a broad overview of the core issues of second language sentence processing research and then narrows its focus by dedicating individual chapters to each of these key areas. While a number of publications have discussed research findings on knowledge of formal syntactic principles as part of theories of second language acquisition, there are fewer resources dedicated to the role of second language sentence processing in this context. This volume will act as the first full-length literature review of the field on the market.

Download or read book Lexical Ambiguity Resolution written by Steven L. Small and published by Elsevier. This book was released on 2013-10-22 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most frequently used words in English are highly ambiguous; for example, Webster's Ninth New Collegiate Dictionary lists 94 meanings for the word "run" as a verb alone. Yet people rarely notice this ambiguity. Solving this puzzle has commanded the efforts of cognitive scientists for many years. The solution most often identified is "context": we use the context of utterance to determine the proper meanings of words and sentences. The problem then becomes specifying the nature of context and how it interacts with the rest of an understanding system. The difficulty becomes especially apparent in the attempt to write a computer program to understand natural language. Lexical ambiguity resolution (LAR), then, is one of the central problems in natural language and computational semantics research. A collection of the best research on LAR available, this volume offers eighteen original papers by leading scientists. Part I, Computer Models, describes nine attempts to discover the processes necessary for disambiguation by implementing programs to do the job. Part II, Empirical Studies, goes into the laboratory setting to examine the nature of the human disambiguation mechanism and the structure of ambiguity itself. A primary goal of this volume is to propose a cognitive science perspective arising out of the conjunction of work and approaches from neuropsychology, psycholinguistics, and artificial intelligence--thereby encouraging a closer cooperation and collaboration among these fields. Lexical Ambiguity Resolution is a valuable and accessible source book for students and cognitive scientists in AI, psycholinguistics, neuropsychology, or theoretical linguistics.

Download or read book Computational Lexical Semantics written by Patrick Saint-Dizier and published by Cambridge University Press. This book was released on 1995-02-24 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lexical semantics has become a major research area within computational linguistics, drawing from psycholinguistics, knowledge representation, and computer algorithms and architecture. Research programs whose goal is the definition of large lexicons are asking what the appropriate representation structure is for different facets of lexical information. Among these facets, semantic information is probably the most complex and the least explored. Computational Lexical Semantics is one of the first volumes to provide models for the creation of various kinds of computerized lexicons for the automatic treatment of natural language, with applications to machine translation, automatic indexing, and database front-ends, knowledge extraction, among other things. It focuses on semantic issues, as seen by linguists, psychologists, and computer scientists. Besides describing academic research, it also covers ongoing industrial projects.

Download or read book Zero Syntax written by David Michael Pesetsky and published by MIT Press. This book was released on 1996 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis and theory developed in Zero Syntax is an important contribution to the understanding of Universal Grammar. The overriding theme is the notion that the availability and syntactic positioning of arguments is not a matter of chance but arises from laws governing the structure of lexical entries and from laws governing syntactic structures themselves. Along the way, Zero Syntax also examines issues of broad significance to current theoretical linguistic research in syntax and lexical semantics. Zero Syntax develops two main topics: a simple view of syntactic linking regularities that it defends in the domain of Experiencer predicates (predicates such as annoy), and a theory of syntactic constituency that involves two parallel modes of structural organization (one of which is the Cascade syntax). The theme that ties these issues together is the supposition that phonologically null (zero) morphology is present in structure, detectable through its syntactic and morphological consequences. The arguments inZero Syntax will be relevant to debates about such issues as empty elements in syntax and morphology, whether syntactic structures should be binary branching, the structure of double-object constructions, and whether verbs have multiple meanings related by lexical rules or abstract/general meanings that are ambiguated in particular constructions.
